We are committed to fostering a healthy work‑life balance and building meaningful connections, ensuring you have the tools, resources, and support needed to excel in any environment. Together, we’ll unlock your potential and create a lasting impact.

While this is the current structure and we currently have no plans to change, we reserve the right to make changes to the hybrid schedule as needed at the Company’s discretion.

• Develop and maintain automated test scripts and frameworks for firmware testing covering static analysis, unit, integration, and regression testing.
• Measure and increase test coverage over time, making sure to emulate edge cases and failure scenarios.
• With assistance from other teams, design and maintain automated hardware‑in‑the‑loop test hardware to support regression testing. This will include everything from verifying wireless network functionality to testing sensor behavior.
