Senior Automation and Controls Engineer - Beckhoff & Python Verified today

What you will do

Our Automation and Controls team builds bespoke test infrastructure that qualifies spaceflight hardware for orbit. You will design, build, and own sophisticated ground support equipment (GSE) and test systems including propulsion test stands, environmental qualification chambers, and spacecraft-level integration testing. Our stack is modern, including a custom PLC framework and Beckhoff EtherCAT tooling built in-house. You will have a meaningful impact on architecture decisions and define standards that will outlast any single program.

• Design, build, and maintain test systems and ground support equipment (GSE) for flight hardware qualification and manufacturing operations.
• Integrate with external hardware including thermal vacuum chambers, ovens, chillers, pressure systems, data acquisition hardware, and precision instrumentation.
• Develop and extend Varda's internal PLC framework and EtherCAT tooling to support evolving program needs.
• Contribute to architecture decisions on real-time control implementation, including evaluation of PLC-based (TwinCAT 3) versus 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 on aggressive timelines.
• Champion sustainable engineering practices that enable new engineers to ramp quickly on the tech stack and maintain production systems reliably.

What you will bring

• Bachelor's degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or a related field.
• 5+ years of industry experience in test automation, controls, and/or industrial automation.
• Hands-on experience integrating with industrial hardware over protocols such as EtherCAT, Modbus (TCP/RTU), RS-232/485 serial, or similar communication standards.
• Experience with at least one modern PLC ecosystem, ideally Beckhoff TwinCAT 3 with structured text (IEC 61131-3), or demonstrated eagerness to develop deep expertise there.
• Comfort working across the full stack: writing control software, designing electrical panels, wiring cabinets, and debugging hardware.
• Proven ability to thrive in a fast-paced startup environment where priorities shift and end-to-end ownership of problems is expected.

What would be a plus

• Strong intuition for when to use real-time PLC code versus higher-level Python orchestration, and understanding of the tradeoffs between the two.
• Experience working with custom or in-house control frameworks, rather than relying solely on vendor-provided stacks.
• Advanced EtherCAT expertise beyond consumer-level usage, including DC sync, ENI configuration, master implementation, or driver-level work.
• Production experience with TwinCAT 3, structured text, and the broader IEC 61131-3 language suite.
• Experience designing deterministic, hard real-time control loops with sub-millisecond cycle times.
• Familiarity with time-series data acquisition and visualization tools such as Grafana, InfluxDB, or similar platforms.
• Aerospace experience, particularly in spacecraft testing or GSE development.
• Environmental test experience, including TVAC, thermal cycling, and vibration testing.
• Hands-on experience working with high-pressure gas or fluid systems.
• Experience developing propulsion test stands or other complex, multi-subsystem test infrastructure.
• Familiarity with spacecraft qualification standards and associated documentation requirements.
• Experience developing safety-related control systems and evaluating proposed solutions for reducing safety-related risks.

Compensation

• Salary range: $140,000 to $179,000 annually.
• Eligible for incentives in the form of stock options and/or long-term cash awards.
• This role is on-site in El Segundo, California.
• Base salary determined by job-related skills, education level, experience level, and job performance.
