Backend developer Jobs in Warren, MI

The right candidate brings strong C++ proficiency and hands-on experience with vehicle communication protocols.

What You Will Work On

•Implement mobile-to-vehicle communication features — including OTA software updates, key fob management, and diagnostics — across iOS and Android, working within architecture and patterns defined by the feature owners.

• Write and review code that interfaces with ECUs and parses DID/DTC data via CAN bus protocols.

• Apply C++ knowledge to bridge ECU diagnostic specs and firmware interfaces into the mobile layer — reading specs, reasoning about low-level behavior, and flagging integration risks early.

• Contribute to end-to-end quality: unit tests, integration tests, and vehicle-in-the-loop tests on the software buck.

• Participate in code reviews with a high bar, flagging complexity and correctness issues within your areas of contribution.

• Collaborate closely with full-time engineers, vehicle engineering, and firmware teams to understand protocol constraints and translate them into clean, reliable implementations.

Required

• 7+ years of professional software development experience, with at least 3 years in mobile (iOS, Android, or React Native).

• Strong C++ proficiency — memory management, concurrency primitives, low-level debugging. You can read firmware and ECU diagnostic specs without needing a translator.

• Hands-on experience with CAN bus and UDS protocols. You have written production code that interfaces with hardware, not just APIs.

• Proficiency in at least one modern application language (TypeScript, Kotlin, or Swift) alongside C++.

• Ability to work effectively within an established architecture — you execute with high quality inside a defined system and communicate clearly when you see gaps or risks.

• Strong command of version control, code review, CI/CD, and testing practices in a mobile context.

• Experience with automotive diagnostics concepts: DTCs, DIDs, ODX/PDX specifications, or OBD-II tooling.

• Bachelor of Science in Computer Science, Electrical Engineering, Computer Engineering, or equivalent professional experience.

Nice to Have

• Experience with React Native in a production environment.

• Experience with CAN/Vector tooling (CANalyzer, CANoe, or equivalent).

• Experience on a software buck, HIL, or similar physical test environments.

• Familiarity with Datadog, k6, or similar observability and performance tooling.

- Test‑driven development mindset
