ABOUT US Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ ABOUT THE ROLE At Ruby Labs, we are looking for a Senior Desktop Engineer to own and drive a new cross-platform desktop product from first commit to production. This is a high-ownership role with an unusually deep systems component. The application is not a wrapped web app: it captures system and microphone audio in real time, renders an always-on-top overlay across the user's workspace, registers global shortcuts, and integrates with the operating system at a level that requires native code on both macOS and Windows. Our architecture is Electron for the application and UI layer, with native modules and helper processes in Swift and C++ where the platform requires it. You will own that boundary, deciding what belongs in TypeScript, what belongs in native code, and making the two halves behave as one reliable product. You will also own everything that happens after the build: code signing, notarization, entitlements, permission onboarding, auto-update, and crash reporting. On this product, those are not an afterthought; they are a significant share of the engineering work, and getting them wrong is what stops users from ever running the app. You will operate as the senior technical voice for desktop within your team, setting the engineering standard for the platform. KEY RESPONSIBILITIES DESKTOP APPLICATION & ENGINEERING QUALITY • Own the Electron architecture end to end — main, renderer and helper processes, IPC design, context isolation, process lifecycle — and deliver major features within agreed timelines. • Build transparent, frameless, always-on-top overlay windows that behave correctly across full-screen spaces, multiple displays and mixed-DPI setups, alongside global shortcuts, tray presence and low-latency UI under continuous background load. • Design a clean platform abstraction in TypeScript so the macOS and Windows implementations stay isolated and independently testable, and write idiomatic Swift and C++ in the native layer. • Keep the product reliable: defensive handling of unstable platform APIs, tests and code reviews, performance, memory and battery budgets, and remediation of security-review and penetration-test findings within agreed severity SLAs. NATIVE PLATFORM INTEGRATION • Build and maintain the native layer: Node addons (N-API / node-addon-api) and out-of-process helpers in Swift and C++. • Implement real-time system audio capture — Core Audio process taps and ScreenCaptureKit on macOS, WASAPI loopback on Windows — including device change handling, format negotiation and graceful recovery from driver-level failures. • Integrate with the Accessibility API (AXUIElement) on macOS and UI Automation on Windows to read application context reliably. • Own the IPC protocol and lifecycle between Electron and the native helpers, and keep the application working as Apple and Microsoft change their platforms. DISTRIBUTION, PERMISSIONS & RELEASE RELIABILITY • Own code signing and notarization on macOS — hardened runtime, entitlements, nested binary signing, provisioning profiles — and Authenticode signing, SmartScreen reputation and antivirus false positives on Windows. • Design the permission onboarding flow — microphone, system audio, screen recording, accessibility — so that grant rates stay high and failure states are recoverable. • Build and maintain the release pipeline: CI matrix builds, signing from CI with HSM-backed certificates, auto-update, staged rollout and rollback. • Own crash reporting and production telemetry for the desktop client, and act on what it tells you. QUALIFICATIONS • 6+ years of software engineering experience, including production-grade TypeScript/Node.js. • 3+ years building and shipping Electron applications to real end users, not internal tools or proofs of concept. • Hands-on native macOS development in Swift and/or Objective-C, with AppKit and at least one system-level framework such as Core Audio, AVFoundation, ScreenCaptureKit, or the Accessibility API. • Practical experience writing native Node addons (N-API / node-addon-api) or bundling and communicating with out-of-process native helpers. • Demonstrated experience with macOS code signing, notarization, entitlements, and the TCC permission model — you have debugged a rejected notarization and know how to read the log. • Working knowledge of the Windows desktop platform: Win32 APIs, Authenticode signing, and the practical realities of SmartScreen and antivirus reputation. • Strong grasp of multi-process architecture, IPC, and debugging issues that only …

ABOUT US Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ ABOUT THE ROLE We are building a category-defining document management platform. We are way past the MVP stage, battle-tested in production, recently profitable, serving hundreds of thousands of customers globally. We are rapidly scaling with multiple products and new funnels. Currently, we are looking for a Senior CRO Manager who thrives on ownership, speed, and building things that scale. Not a 9-5. Read on if you want challenge, autonomy, and fast growth. This isn't a hand-off role. You'll own the full optimization loop end-to-end: deep funnel analysis, hypothesis generation, high-fidelity wireframes and visual specs, working directly with engineers, and the performance outcomes that follow. We are not just looking at landing page optimizations, in this role you'll be working across the entire user journey, from acquisition through activation, retention, and monetization. The pace is fast and iterative. We ship in days, learn, and keep the engine running. We've built a compensation structure that directly rewards people who exceed targets. Top performers see meaningful financial upside tied to their impact. KEY RESPONSIBILITIES • Own end-to-end optimization cycles: research hypothesis design test rollout, while keeping the cycles short. • Use AI tools daily to accelerate research, ideation, design, analysis, and documentation. This is core to how we work, not an afterthought. • Perform deep funnel and product analysis across the full user journey - acquisition, activation, retention, monetization - plus competitive benchmarking to surface high-impact opportunities. • Design high-fidelity wireframes and visual specs that clearly communicate your vision while protecting brand integrity. We're a code-first team - design is built in Next.js and TailwindCSS, not Figma. • Partner with engineers to ensure flawless test implementation and rapid deployment. • Analyze results with statistical rigor and make confident scaling decisions. • Document learnings and maintain a continuously prioritized testing roadmap. • Present insights and results clearly to stakeholders, building alignment and momentum. QUALIFICATIONS • Proven CRO results: 3+ years of hands-on CRO experience, ideally with subscription or SaaS funnels, with documented performance lifts. • Funnel + product thinking: You don't just optimize landing pages. You think about the full user journey and how product decisions compound with funnel decisions. • AI-native workflow: You actively integrate AI into your daily process - prompting, prototyping, analyzing, drafting - and have opinions about what actually works. Almost a must. • Design taste: Strong UI/UX sensibility and the ability to recognize and create ideas that convert. You can build compelling, detailed visual specs yourself. • Speed and iteration: Bias for shipping. You'd rather get two well-designed tests live today than one perfect test in a week, and you keep the cycle moving. • Analytical depth: Skilled in Mixpanel, GrowthBook, Google Analytics, or similar. • Execution excellence: Remarkable attention to detail in fast-moving environments. • Ownership: Self-driven, proactive, fully accountable for outcomes. • Fluent English: strong written and verbal communication. NICE TO HAVE • Exposure to marketing attribution models, UTM parameters, and ROAS measurement. • Strong project management skills with the ability to prioritize and execute quickly. • Bachelor's degree in a relevant field.
