Full-Stack Engineer

About the Role
We're building a cross-platform Electron desktop application for real-time instrument control and signal visualization TypeScript and React in the renderer, and a Node main process owning device I/O, session state, and persistence. You will work on both sides of that boundary and on the IPC contract itself, while also owning our real-time data interfaces, hardware/processing integrations, and the release pipeline that ships the app to end users.

Responsibilities

• Own application architecture across the renderer/main process boundary, including the IPC contract: message schemas, lifecycle, error propagation, and backpressure.
• Build real-time data interfaces — live signal plotting, frequency-domain and band-power views, spectrograms, a node-graph pipeline editor, and dockable multi-viewport layouts.
• Handle continuous multi-channel streams at kilohertz sample rates through decimation, buffering, worker offloading, and canvas/WebGL render loops held to a frame budget.
• Optimize for sustained throughput under load, not just one-off performance wins.
• Integrate the application with instrument hardware and a separate signal-processing engine across process and network boundaries.
• Work through native interfaces where a JavaScript path isn't suitable.
• Define and version wire contracts, handle binary payloads, and diagnose faults that cross process/network boundaries.
• Own build, packaging, and release: signed and notarized installers for macOS, Windows, and Linux.
• Manage artifact publication and an OTA update channel for installed clients.
• Maintain and troubleshoot automated cross-platform CI/CD pipelines, including their failure modes.

Requirements

• 3+ years building production web or desktop applications.
• Strong TypeScript and modern React, with a solid grasp of renders, effects, and state boundaries.
• Real Node.js experience, either server-side or in a desktop main process.
• Demonstrated ability to own a feature end-to-end — data layer, UI, and the release that ships it.
• Working knowledge of CI/CD — able to read a pipeline, diagnose a failed job, and fix it.
• Git fluency and clear written communication, since project context lives largely in commits and tickets.

Strongly Desirable

• Experience with Electron, including its process model and IPC security.
• Desktop packaging and release experience — installers, versioning, code signing, notarization.
• Auto-update / OTA implementation for desktop applications.
• Cloud delivery experience — publishing and hosting build artifacts, along with related access control.
• CI pipeline authoring, ideally with cross-platform builds.

Nice to Have

• VS Code extension development or other editor/IDE tooling experience — we're growing our internal developer tooling.
• C++ or another systems language — our processing engine is written in it, and the ability to read, trace, or contribute to it is valuable.
• Native build tooling — CMake, cross-platform compilation, dependency management, and build debugging.
• Native addons or FFI from Node, bridging native libraries into a JavaScript runtime.
• Real-time data visualization experience — canvas/WebGL charting or a signal-processing background.
• Monorepo tooling at scale.
• Storybook and design-system work.
• Exposure to scientific instruments, medical devices, or hardware-adjacent software.
