About the role
- Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, Blue Origin, and Apple.
- We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall.
- This is not a traditional test software role.
Responsibilities
- Design and build the software infrastructure that powers testing across Endurance, from component qualification through full integrated system validation
- Architect and implement hardware-in-the-loop (HITL) and simulation environments that allow firmware and controls software to be tested under realistic operating conditions and failure scenarios
- Develop software for automated test execution, operator interfaces, data acquisition, visualization, storage, and analysis
- Design and integrate the electrical and controls infrastructure behind new test systems, including DAQs, PLCs, VFDs, sensors, instrumentation, and industrial communication networks
- Partner closely with firmware, electrical, mechanical, controls, and systems engineers to rapidly develop new testing capabilities
- Build scrappy one-off test systems when speed matters, then evolve successful concepts into scalable engineering infrastructure
- Write production-quality software while establishing the architecture and engineering patterns that future test systems will build upon
- Own the technical foundation of Endurance's testing ecosystem as it grows from individual laboratory experiments to full power plant validation
- As a Senior Test Infrastructure Software Engineer at Endurance, you will build the software, controls, and electrical infrastructure that allows our engineering team to rapidly validate every component and every subsystem that goes into a subsea geothermal power plant.
- The next day you may be writing Python services, building hardware-in-the-loop (HITL) simulations, architecting automated test frameworks, or developing software that injects faults to break our control systems before the ocean does.
Requirements
- 5+ years of software engineering experience
- Experience interfacing software with physical hardware, instrumentation, embedded systems, or industrial equipment
- Comfort working hands-on in the lab, including wiring sensors, debugging electrical systems, integrating instrumentation, and bringing up new test hardware
- Track record building software for hardware systems, including automated testing, hardware-in-the-loop (HITL), industrial controls, robotics, aerospace, automotive, or other complex electromechanical products
- Technical fluency strong enough to hold credibility with mechanical, electrical, firmware, and systems engineers
- Ability to work onsite in Seattle and travel to deployment sites as required
Nice to have
- Strong software engineering skills, particularly in Python, with experience in C, C++, Rust, or similar systems programming languages preferred
Skills
- Experience building hardware-in-the-loop (HITL) or software-in-the-loop (SITL) environments
- Experience with industrial automation platforms including PLCs, DAQs, VFDs, National Instruments, Beckhoff, Siemens, or similar systems
- Familiarity with industrial communication protocols such as EtherCAT, CAN, Modbus, or OPC UA
- Experience designing data acquisition and telemetry systems for hardware development
- Background in aerospace, robotics, automotive, energy, defense, or other fast-paced hardware industries
