Software Engineer - XIL Platform

Meet the team:

The XIL Platform team is the vital bridge between our software and the real-world environment. We are part of the Software Foundations & Architecture organization, and our core mission is to build the Middleware, Testing, Simulation, and Hardware-in-the-Loop (HIL) infrastructure  for Glydways. We don't just write test scripts; we build the overarching frameworks that allow those tests to run seamlessly across software, simulation, and physical hardware. We ensure that the software powering our autonomous transit systems is safe, performant, and reliable before a vehicle ever hits the track.

Roles & Responsibilities:

As part of this role you’ll be responsible for:

• Design and architect unified testing frameworks that enable seamless portability of test cases across Software-in-the-Loop (SIL), Hardware-in-the-Loop (HIL), and simulation environments.
• Build, configure, and maintain physical HIL benches and associated hardware interfaces (e.g., CAN adapters) to simulate real-world vehicle environments.
• Integrate automated HIL testing directly into the Continuous Integration (CI) pipelines, ensuring code stability and preventing regressions prior to merging.
• Collaborate closely with software engineering teams to understand their needs, identify and implement improvements in our  Hardware-in-the-Loop (HIL) Infrastructure and Continuous Integration (CI) systems.
• Monitor and report on runtime performance, system health, and reliability metrics across all HIL testing platforms.

Knowledge, Skills and Abilities:

• Professional C++ experience building and maintaining libraries and test frameworks — not just modifying existing code. Our framework is C++ end to end: test fixtures, simulators, monitors, and every test case. This includes fluency with GoogleTest or an equivalent (fixtures, parameterized tests) and diagnosing flaky, timing-sensitive failures. You will write C++ on day one.
• Deep understanding of Hardware-in-the-Loop (HIL), Software-in-the-Loop (SIL), and simulation testing strategies, particularly for safety-critical systems.
• Python and Bash for CI tooling, bench automation, and scripting is a plus.
• Strong knowledge of CI/CD best practices and principles. Direct experience with Buildkite is a plus.
• Hands-on ability to troubleshoot physical test benches, including reading electrical schematics and using lab tools like oscilloscopes, multimeters, and PCAN adapters.
• Experience using infrastructure-as-code and environment management tools (specifically Nix, or similar tools like Docker/Ansible) to ensure reproducible test environments.
