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.
