Full Job Description
About This Role
The Senior Mechanical Design & Test Engineer, Automation builds bespoke test infrastructure that qualifies spaceflight hardware for orbit. They design, build, and own sophisticated ground support equipment (GSE) and test systems: propulsion test stands, environmental qualification chambers, spacecraft-level integration testing and more! Our stack is modern, including a custom PLC framework and Beckhoff EtherCAT tooling built in-house.
Enable high cadence, production enabling equipment is priority #1.
Integrate mechanical, electrical, fluid, and instrumentation systems into cohesive test platforms.
Implement solutions from concept through fabrication, assembly, commissioning, and ongoing support.
Manage both rapid R&D test setups and long-term test infrastructure improvements.
Responsibilities
Design, build, and maintain test systems and ground support equipment (GSE) for flight hardware qualification and manufacturing operations including data acquisition systems (Pelican DAQ, Load cell DAQ, Accelerometer DAQ, prop test stands, fill carts), thermal control systems (chillers, heaters, Ln2), PLC cabinets, and gas/liquid systems (valves, ducers, solenoids, flowmeters).
Test infrastructure achieves >99% uptime and predictable performance.
Be the "Responsible Engineer" for test infrastructure including centrifuges, TVACs, prop test stands, prop fill carts, prop gas benches, prop water flow stands and torch test stands.
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.
Read, deploy and make minor edits to Varda's internal PLC framework and EtherCAT tooling to support evolving program need.
Champion sustainable engineering practices that enable new engineers to ramp quickly on the tech stack and maintain production systems reliably. All systems are thoroughly documented, with clear, accessible procedures and schematics.
Basic Qualifications
Bachelor's degree in Mechanical Engineering, or related technical field.
5+ years of industry experience in mechanical design or industrial automation.
Extensive experience using Solidworks, NX CAD or comparable.
Experience with electrical wiring for cabinets, PLCs, harnesses, connectors, etc.
Experience with Altium or comparable electronic schematic design software. We are migrating to EPLAN!
Hands-on experience working with high-pressure gas or fluid systems.
Environmental test experience, including TVAC, thermal cycling, and vibration testing.
Experience developing propulsion test stands or other complex, multi-subsystem test infrastructure.
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 a demonstrated eagerness to develop deep expertise there.
Proven ability to thrive in a fast-paced startup environment where priorities shift, and end-to-end ownership of problems is expected.
Preferred Skills and Experience
Aerospace experience, particularly in spacecraft testing or GSE development.
Familiarity with spacecraft qualification standards and associated documentation requirements.
Experience developing safety-related control systems and evaluating proposed solutions for reducing safety-related risks.
Programming, either low level firmware or high-level Python.
Pay Range
Salary range: Senior: $140,333 - $179,314/ per year.
This role is on-site in El Segundo, CA.
Leveling and base salary is determined by job-related skills, education level, experience level, and job performance.
You will be eligible for incentives in the form of stock options and/or long-term cash awards.
