We enable scalable, production-like validation across hardware, firmware, and distributed software systems to ensure our devices behave correctly in real-world conditions and that critical customer journeys function reliably before reaching production.

We are seeking a Software Engineer to lead TPS’s technical vision while leading a team of engineers. This role combines hands-on architectural ownership with people leadership, execution accountability, and technical mentorship.

This is a highly collaborative position partnering closely with Infrastructure, Backend, Firmware, and Monitoring teams to ensure our validation platforms evolve alongside product and system complexity. It’s ideal for a leader who wants to remain deeply technical while shaping a high-impact engineering team responsible for validating complex, distributed systems at scale.
