Principal Software Engineer

WHAT YOU’LL DO 1. Act as the technical lead for large parts of the scanner platform: system architecture, codebase structure, and long-term maintainability. 2. Own core runtime foundations: distributed control, state management, fault handling, and reliability. 3. Drive engineering rigor: testability, code quality, review standards, performance regression prevention, and release processes. 4. Build robust observability: logs, metrics, traces, and replayable diagnostics (with privacy constraints). 5. Collaborate with hardware and recon/ML teams to define interfaces, data contracts, timing/synchronization, and failure modes. 6. Lead complex refactors (e.g., message passing / RPC boundaries, modularization, concurrency model) without halting forward progress. WHAT WE’RE LOOKING FOR • Deep software architecture experience for real-world systems: robotics, instrumentation, medical devices, or other complex distributed products. • Strong Python and concurrency background (asyncio, multiprocessing, profiling, performance engineering). • Track record of shipping systems that are observable, debuggable, and resilient. • Strong technical leadership: clarity, pragmatic trade-offs, and mentoring. USEFUL EXPERIENCE • Building but rock-solid systems: clear interfaces (gRPC/protobuf or equivalent), strong state modeling, and failure handling. • High-leverage engineering habits on a lean team: good tests, CI, reproducible dev environments, and fast code review. • Practical performance + concurrency work in Python (asyncio, profiling, multiprocessing) and comfort debugging distributed behavior. • Security-minded device software: safe defaults, encrypted data paths, and disciplined handling of PII/PHI. • Operational thinking: remote updates/management, excellent logging, and diagnostics that make real hardware debuggable.
