C++ Embedded Mobile Developer

TEKsystems•Troy, NY

3d•$65 - $75•Hybrid

About The Position

This is an experienced individual contributor contract role embedded within a customer's Mobile Experience pod. The role involves working alongside and in support of full-time engineers who own the architecture and feature roadmap for mobile-to-vehicle communication. The primary focus is execution: taking well-scoped work and delivering it with the quality, discipline, and embedded systems fluency required for this domain. The ideal candidate possesses strong C++ proficiency and hands-on experience with vehicle communication protocols. While React Native is the delivery environment, the core challenges lie in low-level systems, requiring a candidate with a deep understanding of these aspects.

Requirements

7+ years of professional software development experience, with at least 3 years in mobile (iOS, Android, or React Native).
Strong C++ proficiency, including memory management, concurrency primitives, and low-level debugging. Ability to read firmware and ECU diagnostic specs without assistance.
Hands-on experience with CAN bus and UDS protocols. Experience writing production code that interfaces with hardware, not just APIs.
Proficiency in at least one modern application language (TypeScript, Kotlin, or Swift) in addition to C++.
Ability to work effectively within an established architecture, executing with high quality within a defined system and communicating clearly about gaps or risks.
Strong command of version control, code review, CI/CD, and testing practices in a mobile context.
Experience with automotive diagnostics concepts such as DTCs, DIDs, ODX/PDX specifications, or OBD-II tooling.
Bachelor of Science in Computer Science, Electrical Engineering, Computer Engineering, or equivalent professional experience.

Responsibilities

Implement mobile-to-vehicle communication features, including OTA software updates, key fob management, and diagnostics, across iOS and Android, working within the 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, which includes reading specs, reasoning about low-level behavior, and proactively identifying integration risks.
Contribute to end-to-end quality through unit tests, integration tests, and vehicle-in-the-loop tests on the software buck.
Participate in code reviews with a high standard, identifying complexity and correctness issues within their 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.
