Spacecraft Ground Support Equipment Software Engineer
About The Position
Low Earth orbit is open for business. Varda is accelerating the development of commercial space infrastructure, from in-orbit pharmaceutical processing to reliable and economical reentry capsules. From life-saving pharmaceuticals to more powerful fiber optics, there is a world of products used on Earth today that can only be manufactured in space. Varda is accelerating innovation in the orbital economy by creating both the products and infrastructure needed so space can directly benefit life on Earth. Our mission is to expand the economic bounds of humankind. Our team is uniquely suited to accomplishing this goal, with leadership and staff comprised of veterans from SpaceX, Blue Origin, major pharmaceutical companies and Silicon Valley. Varda was founded in January 2021 by Will Bruey and Delian Asparouhov with significant backing from world class investors including Khosla Ventures, Lux Capital, Founders Fund, Caffeinated Capital, General Catalyst, and Also Capital. Varda is headquartered in El Segundo, California, where we have offices and a production facility where our vehicles, equipment, and materials are built, integrated, and tested. Varda also has offices in Washington, DC and Huntsville, AL. Join Varda, and work to create a bustling in-space ecosystem.
Requirements
- Bachelor's degree in computer science, math, physics, engineering or equivalent technical experience in safety critical software.
- 5+ years of industry experience in test automation, controls, or industrial automation.
- Strong Python skills, particularly for hardware control or test automation applications.
- Hands-on experience integrating with industrial hardware over protocols like EtherCAT , Modbus ( TCP/TRU) , serial (RS232/485) , or similar.
- Experience with at least one modern PLC ecosystem, ideally Beckhoff TwinCAT 3 with structured text (IEC 61131-3) or willingness to develop deep expertise there.
- Comfort working across the stack: writing control software, designing electrical panels, wiring cabinets, debugging hardware.
Nice To Haves
- EtherCAT experience beyond consumer-level usage — DC sync, ENI configuration, master implementation, or driver-level work.
- Production experience with TwinCAT 3, structured text, and the broader IEC 61131-3 languages.
- Experience designing deterministic, hard real-time control loops (sub-millisecond cycle times).
- Understanding of when to use real-time PLC code vs. higher-level orchestration in Python.
- Bare-metal or embedded firmware experience.
- Experience with time-series data acquisition and visualization (Grafana, InfluxDB , or similar).
- Environmental test experience: TVAC, thermal cycling, vibration.
- Hands-on experience with high-pressure gas or fluid systems.
- Experience developing propulsion test stands or other complex test infrastructure.
- Experience developing safety- related control systems and evaluating proposed solutions for reducing safety- related risks.
Responsibilities
- Design, build, and maintain test systems and ground support equipment for flight hardware qualification and manufacturing.
- Integrate with a wide range of external hardware: thermal vacuum chambers, ovens, chillers, pressure systems, data acquisition hardware, and instrumentation.
- Develop and extend our internal PLC framework and EtherCAT tooling.
- Contribute to architecture decisions on real-time control implementation, including evaluation of PLC-based (TwinCAT 3) vs. Linux-based approaches for high-frequency control applications.
- Build cabinets, wire panels, and own systems end-to-end from electrical design through commissioning.
- Partner with propulsion, avionics, GNC, and manufacturing teams to deliver test infrastructure that meets their needs on aggressive timelines.
- Demonstrate sustainable engineering practices that help onboard new engineers to the tech stack and maintain production systems.
Benefits
- Equity in a fully funded space startup with potential for significant growth (interns excluded)
- 401(k) matching (interns excluded)
- Unlimited PTO (interns excluded)
- Health insurance, including Vision and Dental
- Lunch and snacks provided on site every day.
- Dinners provided twice a week.
