Job Description

We're seeking a Test Development Engineer to lead end‑to‑end testing for Brill Power's Battery Intelligence Platform, covering BMS and DC/DC systems. You'll design test strategies, build automation (Python, GitLab CI), and execute environmental, reliability, and compliance campaigns to generate high‑quality evidence for product confidence and certification. Working closely with electronics, firmware, and manufacturing, you'll root‑cause issues, validate fixes, and contribute to qualification against relevant standards.

The Role

Own test strategy and plans for BMS/DC/DC features, safety functions, and system performance. You'll design test strategies, build automation (Python, GitLab CI), and execute environmental, reliability, and compliance campaigns to generate high‑quality evidence for product confidence and certification. Working closely with electronics, firmware, and manufacturing, you'll root‑cause issues, validate fixes, and contribute to qualification against relevant standards.

Job Overview and responsibilities

• Develop automated test frameworks and pipelines (Python, GitLab CI) for firmware, HIL, and system testing.
• Design and execute environmental, reliability, and compliance test campaigns; analyze results and drive corrective actions.
• Build and maintain instrumentation setups (oscilloscopes, power analyzers, DAQ) and data workflows.
• Author clear test artefacts: procedures, scripts, datasets, reports, and traceability.
• Partner with design, firmware, and manufacturing to root‑cause issues and validate fixes.
• Contribute to qualification toward relevant standards (e.g., DO‑160, IEC 61508, UN 38.3, functional safety).

Skills and Experience

What you'll bring (we don't expect every box ticked)

• Hands‑on with instrumentation (oscilloscopes, power analyzers, DAQ) and data analysis
• Familiarity with reliability, environmental, and compliance testing (e.g., DO‑160, IEC 61508)
• Strong documentation, version control, and CI/CD practices for test artefacts
• Collaboration with design, firmware, and manufacturing to root‑cause and resolve issues
• Structured problem‑solving, clear communication, and a bias for action

Successful candidates will have experience with the following:

• Experience with hardware/software test development (Python, GitLab) and test automation

• Structured problem‑solving, clear communication, and a bias for action

Nice to Have

• Experience with HIL frameworks, CAN/Ethernet test tooling, and embedded logging
• Exposure to aerospace battery standards (DO‑311A), UN 38.3 transport tests, or AS9100 QMS practices
• Power electronics test of DC/DC converters, fault injection, and thermal characterization

Working Style

• Fast-learner, eager to pick up new technologies
• Pragmatic; comfortable with ambiguity and changing requirements
• Able to work autonomously
• Comfortable working in a small team with a diverse range of responsibilities
