Principal Thermal Protection System Engineer

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

We are looking for a Principal TPS Engineer to lead the definition, development, and delivery of the Thermal Protection System (TPS) for Nyx. This role combines deep technical ownership with subsystem leadership, ensuring robust, traceable, and flight-ready TPS solutions aligned with overall spacecraft needs.

Key Responsibilities

• Own the TPS architecture and design, ensuring consistency with system-level constraints and interfaces (structures, avionics, propulsion, etc.).

• Lead trade-offs and technical decisions, balancing performance, reliability, manufacturability, cost, and schedule.

• Drive modelling and analysis activities, ensuring high-quality predictions, assumptions traceability, and correlation with test results.

• Define and oversee TPS hardware development and qualification, including supplier interaction and flight model delivery.

• Establish and execute verification and test strategies, from component level to integrated system validation.

• Manage technical risks, reviews, and progress tracking, ensuring timely escalation and mitigation actions.

• Lead and mentor the TPS engineering unit, defining priorities, supporting growth, and ensuring delivery excellence.

• Act as a hands-on technical leader, actively contributing to design, analysis, test preparation and troubleshooting, with strong proximity to integration and MAIT activities.

• Own and structure the TPS laboratory environment, ensuring the right capabilities, workflows, and test practices are in place to support development, qualification, and iteration speed.
