Learn more about our story at: /p h3About The Role /h3 pAt 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. /p pThis 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. /p pOur 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. /p pYou 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. /p pYou will operate as the senior technical voice for desktop within your team, setting the engineering standard for the platform. /p h3Desktop Application Engineering Quality /h3 ul liOwn the Electron architecture end to end — main, renderer and helper processes, IPC design, context isolation, process lifecycle — and deliver major features within agreed timelines. /li liBuild 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. /li liDesign 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. /li liKeep 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. /li /ul h3Native Platform Integration /h3 ul liBuild and maintain the native layer: Node addons (N‑API / node‑addon‑api)
and out‑of‑process helpers in Swift and C++. /li liImplement 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. /li liIntegrate with the Accessibility API (AXUIElement) on macOS and UI Automation on Windows to read application context reliably. /li liOwn the IPC protocol and lifecycle between Electron and the native helpers, and keep the application working as Apple and Microsoft change their platforms. /li /ul h3Distribution, Permissions Release Reliability /h3 ul liOwn 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. /li liDesign the permission onboarding flow — microphone, system audio, screen recording, accessibility — so that grant rates stay high and failure states are recoverable. /li liBuild and maintain the release pipeline: CI matrix builds, signing from CI with HSM‑backed certificates, auto‑update, staged rollout and rollback. /li liOwn crash reporting and production telemetry for the desktop client, and act on what it tells you. /li /ul h3Qualifications /h3 ul li6+ years of software engineering experience, including production‑grade TypeScript/Node.js. /li li3+ years building and shipping Electron applications to real end users — not internal tools or proofs of concept. /li liHands‑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. /li liPractical experience writing native Node addons (N‑API / node‑addon‑api) or bundling and communicating with out‑of‑process native helpers. /li liDemonstrated 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. /li liWorking knowledge of the Windows desktop platform: Win32 APIs, Authenticode signing, and the practical realities of SmartScreen and antivirus reputation. /li liStrong grasp of multi‑process architecture, IPC, and debugging issues that only reproduce on a user's machine.
/li /ul h3Nice to have /h3 ul liReal‑time audio pipelines — buffering, resampling, mixing multiple sources, or streaming to speech‑to‑text services. /li liSigning from CI with hardware‑backed certificates (Azure Key Vault, DigiCert KeyLocker, or similar), and antivirus whitelisting or SmartScreen reputation building for a new product. /li liAuto‑update infrastructure such as Squirrel, electron‑updater or Sparkle, including staged rollouts. /li liCrash reporting and symbolication for native code (Crashpad, Sentry, or similar). /li liPrior experience shipping a consumer desktop product at meaningful scale. /li /ul h3Location /h3 pRuby Labs operates within the CET (Central European Time) zone.
