Bazel Build & Tooling Engineer

As a Bazel Build & Tooling Engineer, you will shape the foundation of our entire engineering workflow. You design and maintain a scalable Bazel‑based build ecosystem that supports large monorepos, multiple languages and cross‑platform toolchains. Your work ensures our developers can build, test and ship software quickly, reliably and repeatedly.

You’ll own Bazel architecture, build logic quality, remote execution setups, multi‑mode build configurations and cross‑platform toolchains. You’ll collaborate closely with engineering teams to refine build behavior, enforce best practices, and troubleshoot complex build issues. In this role, you elevate build performance, improve developer experience, and ensure our build system remains robust as we evolve our software‑defined vehicle platform.

• Design and maintain clear, scalable Bazel build rules and workspace structure

• Improve build performance, dependency graphs and reproducibility

• Integrate remote execution, remote caching and CI build pipelines

• Support multiple build modes (debug, release, profiling, coverage, sanitizers)

• Contribute to consistent compiler and toolchain configurations

• Support cross‑platform build scenarios (e.g., Linux, Android, QNX)

• Troubleshoot build issues and improve build system reliability

You have strong experience working with Bazel in complex or large‑scale environments. You enjoy working close to the build chain, solving deep build‑related problems and enabling engineers to work efficiently. You value clarity, scalability and predictable build behaviour.

• Strong knowledge of hermetic, sandboxed and incremental build workflows

• Experience with remote execution and caching setups

• Understanding of multi‑language build environments

• Ability to optimize build graphs and diagnose build issues

• Experience in designing and enforcing compiler flag policies for C/C++, including security hardening (PIE, RELRO, stack canaries, FORTIFY) and sanitizer integration (ASan/UBSan/TSan).

• Good Python skills

• Knowledge of other build systems (CMake, Ninja, Make, Gradle, etc.)

• Experience with C++, Rust, Java or Go in Bazel‑based environments

• Familiarity with CI/CD scaling for large engineering teams

You will work at the core of our developer platform, impacting how engineers build, test and deliver software every day. Your work will directly improve productivity, stability and scalability across the organization.

Coretura is a joint venture between Volvo Group and Daimler Truck, building a standardized, open and scalable software‑defined vehicle platform for the next generation of commercial vehicles.
