Remote Jobs

What it's all about The Team: JobLeads helps millions of professionals across 40+ countries find their next role, matching them against millions of live jobs. We are building what we believe will be the best job search on the internet - one that understands what a candidate is actually looking for, even when they can't put it into a keyword. Search, matching, and recommendations sit at the core of our product, and applied AI is how we are already winning there. Your Role: As an Applied AI Engineer, you will build the intelligence behind how candidates and jobs find each other: semantic search, resume-based matching, LLM-driven query understanding, and recommendations. The role evolves with the mission: whatever it takes to make our search the best job search on the internet is what you'll work on next. That makes out-of-the-box thinking a feature of the job, not a nice-to-have - we expect you to bring new approaches, methods, and frameworks to the table, whether they come from commercial model providers or straight from current research. If a paper published last month suggests a better way to retrieve, rank, or evaluate, we want you to be the person who spots it, tests it, and tells us whether it holds up on our data. What stays constant is the way of working: form a hypothesis, benchmark it rigorously against the status quo, make it tangible in a prototype people can play with, ship the winner to production, and prove it in an A/B test. You'll work closely with the people who make the decisions and present your results to them directly - your benchmark can become a production experiment within days. What You'll Be Doing: • Design and improve retrieval systems over a large, messy real-world corpus at scale: embeddings, hybrid search, ranking, and re-ranking • Shape the design of our vector search backbone: how jobs and resumes are represented, which embedding models to use, the right vector dimensionality for each purpose, etc. • Build LLM pipelines for understanding queries, resumes, and jobs — extraction, enrichment, rewriting, matching - choosing the right model and technique for each step • Own evaluation as a scientific discipline , not a checkbox: • Curate benchmark datasets that capture both the failure modes you're fixing and the healthy cases you must not regress • Design LLM-as-judge setups you can defend - ground and calibrate the judge against human sanity checks, detect its biases (a conservative judge will punish a correct query expansion for not being literal), and iterate on the judge itself when it measures the wrong thing • Apply and adapt search-relevance methodology - precision@k, NDCG, pairwise preference testing - choosing metrics that resist gaming, and recognizing when a metric rewards degenerate behavior • Read results like a scientist: cumulative vs. independent effects, why two valid metrics can disagree, what a distribution's tail says that its mean hides • Quantify the full picture - quality, latency percentiles, and cost per query • Build interactive prototypes so product managers and stakeholders can test your approaches hands-on before anything ships • Partner with engineers to bring winners to production faithfully - no gap between what was benchmarked and what ships - and follow through into A/B test readouts • Track the fast-moving model and research landscape and re-evaluate as new models, techniques, and papers appear, keeping us on the best quality-per-euro frontier • See your work impact the way millions of job seekers find their next job in 42 countries • Be surrounded by colleagues who understand you and help you grow in your role What You'll Need: • Degree in Computer Science, AI, or a related field from a top-tier program (e.g., TUM, University of Tübingen, Saarland University, RWTH Aachen, LMU Munich, TU Berlin, KIT, University of Freiburg, University of Bonn, FAU Erlangen-Nürnberg, TU Darmstadt, University of Stuttgart, Heidelberg University, HPI (Hasso Plattner Institute, Potsdam), TU Dresden, Uni Paderborn, or equivalent) • Have hands-on experience building applied ML or LLM systems - retrieval, RAG, agentic pipelines, or traditional search - that real users touched • Have genuine data-science depth : you design experiments, build baselines, and reason about metrics and their failure modes before trusting a number • Are fluent in Python and comfortable owning a pipeline end to end: data, prompts, embeddings, retrieval, evaluation, and the glue in between • Don't trust a demo: you build a baseline, a dataset, and a metric before declaring victory - and you notice when your metric is measuring the wrong thing • Communicate clearly with non-ML colleagues and enjoy making your findings understandable, not just correct • Are pragmatic and 80/20-minded: you'd rather ship a simple approach that captures most of the gain than a complex one that looks better on paper Nice If You Have: • A track record of taking methods from research …

What it's all about The Team: At JobLeads, we believe careers should be shaped with purpose, confidence, and opportunity. That’s why we build technology that helps professionals around the world take control of their career journeys. Behind that mission is our Tech Team, a vibrant, globally distributed group of builders, thinkers, and collaborators who care deeply about the experiences we create. We’re a team that values curiosity, ownership, and human connection. We collaborate across borders and time zones, challenge each other to grow, and celebrate the wins, big and small, along the way. From your very first day, you’ll feel it: this is a place where ideas are welcomed, contributions matter, and people genuinely enjoy working together. Your Role: We’re looking for a Senior Back End Developer who thrives on building elegant systems and meaningful user experiences. In this role, you’ll help shape the architecture and performance of the platform that powers JobLeads, primarily working on our backend systems with PHP and Symfony. But this role goes beyond simply writing code. You’ll help drive technical decisions, influence the evolution of our platform, and play a key part in delivering products that empower millions of professionals worldwide. How We Build: Agentic engineering is how we work, not a pilot project. AI enhanced coding is part of everyday delivery, our merge requests run through an AI review pipeline in CI, and our tech leads each are constantly on the look out for ways to augment our team’s capabilities and to build agent fluency. Not all of us are equally far along yet, but the direction is settled. What we never do is ship code nobody understands. What You’ll Be Doing: • Design and develop scalable backend services using PHP and Symfony, ensuring performance, stability, and maintainability across the platform. • Collaborate closely with product managers, designers, QA engineers, and fellow developers to bring ideas from concept to launch. • Participate in thoughtful code reviews that elevate code quality, strengthen architecture, and support team learning. • Improve the conventions, hooks and review automation that agents rely on. • Take ownership of features from initial concept through implementation, optimization, and continuous improvement. What You’ll Need: • 5+ years of experience in back-end development, delivering production-ready applications. • Strong expertise in PHP and a deep understanding of software design principles and scalable architecture. • Extensive hands-on experience with the Symfony framework. • Routine hands-on work with agentic coding tools (Claude Code, Codex, Cursor or comparable) on production code, not IDE autocomplete. • Spec and verification discipline: quality is decided before the first line of code, and you close the loop with plans, tests and blocking checks rather than trusting output. • Deliberate context management, and real strength at reviewing agent-generated code, where the bottleneck now sits. • Proficiency with Git and modern collaborative development workflows. • Clear and effective communication skills, especially when collaborating with a distributed global team. Nice If You Have: • Experience working with MySQL and ORM frameworks such as Doctrine. • Experience making a large legacy codebase agent-friendly, or with MCP servers. What You Can Expect On Board: • Fully remote work - collaborate with us from wherever you do your best work. • Flexible hours designed to support both productivity and personal balance. • The freedom to choose your preferred equipment so you can work comfortably and effectively. • Competitive compensation aligned with your expertise and impact. • A diverse, supportive team culture that values openness, collaboration, and fresh ideas. • Premium agent tooling with real token headroom and no usage leaderboards. • Opportunities for professional growth through learning resources, training, and conference support. • The chance to build technology that genuinely improves the lives of job seekers around the world. • Memorable team experiences, from EU meetups to our annual company summer getaway. At JobLeads, your work won’t just power a platform, it will help millions of professionals discover new opportunities, pursue meaningful careers, and shape their futures with confidence. If you’re passionate about great technology, inspired by purposeful work, and excited to collaborate with a talented global team, we’d love to hear from you.

What it's all about The Team: We are building the analytical backbone of a company that believes decisions should be powered by clarity, not guesswork. Our Business Intelligence team builds on top of a data platform that has to be there every morning - healthy, current, and trusted. Making that happen takes a core data engineer who owns the operational reliability of our platform end-to-end. Someone the rest of the team can count on to keep the lights on, catch issues before they become incidents, and push the platform forward with us rather than just holding it in place. Your Role: This is a core data engineering role. You own the operational health of our data platform, and you keep making it better. Your working hours - 5 am-2pm CEST - put you in a timezone that naturally overlaps with our overnight processing window. That means overnight maintenance, failed jobs, and quality incidents land inside your normal working day, not at 5am in your bed. You catch them, fix them, and hand over a healthy platform before the European team logs on. We're looking for someone experienced enough to operate independently. You don't need a ticket telling you something is broken - you can read logs, trace through SQL and Python, and figure out what happened. You care about data quality as a craft, and you have the confidence to walk up to a data owner and say "this feed is wrong, here's why, and here's what we should do about it." This isn't a greenfield architecture role. The platform exists, but it is a long way from finished. Roughly half the job is keeping it healthy; the other half is leaving it better than you found it - new source domains modelled properly, quality gates where there are none today, slow queries made fast. Keeping the lights on is the floor here, not the ceiling. How We Work: A large share of what we build is AI-assisted, and some of it is AI-generated. Claude Code, MCP servers, and LLM tooling are part of the daily toolchain across BI, internal tooling, and data pre-processing. Everything lives in Git, ships through GitLab CI/CD, and gets reviewed. That only works because someone puts the rigour in behind it. Generated SQL still has to survive an execution plan. A pipeline an agent wrote still has to be correct at 4am when a source system quietly changes shape. This role is that layer: you will use these tools heavily, and you will be the person who checks what comes out of them - reading the query instead of trusting it, validating numbers against the source, catching the plausible-looking answer that is wrong. So we need someone fluent with AI tooling and unwilling to take its output on faith. Those two things aren't in tension here. Together they are the job. What You'll Be Doing Keep it running: • Monitor overnight processing, resolve failures, and hand a healthy platform to the European team each morning - you are the BI team's first line of operational defense during their off-hours • Keep the orchestration layer healthy: Airflow DAGs and the Python jobs behind them across Windows and Linux VMs - failed tasks, backfills, and dependencies that match how the data actually flows • Investigate and fix recurring issues in our on-prem Microsoft SQL Server environment, including cross-system access through linked servers, OPENQUERY, and PolyBase • Hunt down data quality gaps - stale feeds, broken joins, silently-changing source systems - and drive them to resolution with the data owner Keep making it better: • Extend the platform as the business grows: model new source domains into the warehouse and build data models analysts can use without needing a translator • Build automated data quality gates - freshness, volume, referential integrity, business rules - so bad data fails loudly at the door instead of surfacing in a dashboard three days later • Tune slow SQL - queries, stored procedures, indexes, execution plans - so the platform gets faster, not slower, as the company grows • Turn recurring fixes into permanent ones through better alerting, logging, runbooks, and automation, so the same incident stops coming back • Be the last check on AI-assisted work before it reaches production - review generated SQL and pipeline code, and build the tests that let the rest of the team move fast on top of it What You'll Need • 3+ years of core data engineering experience in a production environment • Microsoft SQL Server professional - stellar T-SQL plus real optimization depth (indexing strategies, execution plans, query tuning, partitioning), the instinct for which of those a slow query actually needs, and comfort reaching across system boundaries with linked servers, OPENQUERY, and PolyBase • Data modelling judgment - you can design warehouse tables and dimensional models that hold up as sources change and analysts ask new questions, and you know where to put a quality gate so it catches problems instead of generating noise • Strong Python and production Airflow - in-depth Python …
