Principal Software Engineering - Build System Modernization

Job Description

Vacancy Status: This posting is not for an existing vacancy within the organization and is open to new applications.

AI Disclosure: As part of the application process, Artificial Intelligence will be used in the hiring process for this role

Work Arrangement: Hybrid: This role is categorized as hybrid. This means the successful candidate is expected to report to Markham or Oshawa office three times per week, at minimum.

The Role: General Motors is seeking a software engineering leader to modernize and scale the build systems that support software-defined vehicles. This role will help lead the transition from a legacy Make-based system to Bazel, Google’s open-source build tool, improving speed, reliability, and robustness across the engineering organization. The successful candidate will drive this capability at scale, influence technical direction across teams, and help establish lofty platform capability goals.

What You'll Do: Lead software engineering productivity and effectiveness by identifying opportunities, shaping strategies, improving processes, guiding change, and connecting initiatives to deliver greater value through innovation, learning, and simplification.

Lead high-impact efforts hands-on, solve complex and unusual problems, and communicate effectively as a coach and mentor while balancing technical command with empathy.

Modernize a large embedded-software build and test system by transitioning legacy Make- or shell-based workflows to Bazel and establishing scalable, reproducible, secure, and developer-friendly infrastructure across repositories, toolchains, CI/CD, testing, and release processes.

Assess current build, test, dependency, toolchain, and hardware workflows to define a phased Bazel migration strategy and rollout model.

Design and implement reusable Bazel rules, macros, toolchains, platforms, configuration patterns, and repository standards, while migrating embedded applications, libraries, generated code, firmware, cross-compilation flows, and platform variants with validated build parity and reproducibility.

Integrate Bazel with enterprise CI/CD, testing, release, artifact, deployment, observability, security, and infrastructure workflows, and optimize the platform through caching, parallelism, reliability practices, documentation, training, legacy Make retirement, and continuous improvement.

Measure success through target repositories migrated with validated build and test parity; faster clean and incremental builds, CI queues, and developer feedback; increased reproducibility, approved hermetic-toolchain adoption, cache effectiveness, and CI capacity; and lower build, pipeline, and flaky-test rates.

Improve diagnosis and recovery time while ensuring complete artifact provenance, test evidence, and security-policy compliance for releases, strong developer adoption, reduced support burden, and measurable productivity improvement.

Hold a bachelor’s degree in software engineering or have equivalent experience, along with 15 years of software development experience.

Bring a deep understanding of real-time software architecture and experience shipping high-quality, safety-critical products in automotive, embedded, safety-related, calibration, or systems-engineering environments.

Demonstrate exceptional problem-solving and analytical abilities, keen attention to detail, and the ability to manage multiple projects and priorities in fast-paced, action-oriented decision-making environments.

Bring strong expertise building and maintaining production software systems, proficiency in Python and at least one additional engineering-tooling language, and experience with AI-assisted developer productivity, coding agents, code intelligence, knowledge retrieval, or workflow orchestration.

Evaluate AI-enabled engineering workflows using measurable quality, adoption, and productivity outcomes.
