Lead architecture and core runtime foundations for a distributed scanner platform, driving reliability, observability, performance, and engineering rigor while collaborating with hardware and ML teams and mentoring engineers.
The summary above was generated by AI
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.

What you need to know about the Calgary Tech Scene

Employees can spend up to one-third of their life at work, so choosing the right company is crucial, not just for the job itself but for the company culture as well. While startups often offer dynamic culture and growth opportunities, large corporations provide benefits like career development and networking, especially appealing to recent graduates. Fortunately, Calgary stands out as a hub for both, recognized as one of Startup Genome's Top 100 Emerging Ecosystems, while also playing host to a number of multinational enterprises. In Calgary, job seekers can find a wide range of opportunities.
