About the Job

Requirements

  • A B.S. in Aerospace Engineering, Mechanical Engineering, or a related discipline is required; equivalent professional experience is considered.
  • At least 6 years of hands-on experience designing, qualifying, or owning fluid components for spacecraft, launch vehicles, or comparable high-pressure hardware, on either the vehicle or component-supplier side.
  • Working understanding of component design fundamentals, including sealing, force balance, spring sizing, friction, flow paths, materials compatibility, material finishes, and wear.
  • Mechanical design proficiency in CAD, assembly management using PLM software, detailed drawings with GD&T per ASME Y14.5, and tolerance analysis.
  • Experience with component pressure and leak testing and ATP/QTP execution per SMC-S-016 or an equivalent standard, including authoring procedures and establishing pass/fail criteria.
  • Hands-on experience building and testing pressurized hardware alongside technicians.
  • A proven record of technical ownership, driving nonconformances and anomalies to root cause and corrective action across teams and suppliers.
  • Willingness to travel to suppliers and test sites as needed, typically under 10% of the time.

Responsibilities

  • Serve as responsible engineer for a significant portion of the bus propulsion component portfolio, from requirements and specification generation through development, qualification, production, and flight, in partnership with the broader engineering team.
  • Design Varda-owned propulsion components, including CAD, detailed drawings with GD&T per ASME Y14.5, tolerance analysis, seal and spring design, and supporting structural and fluid analysis.
  • Specify, source, and qualify purchased components; serve as a technical lead with suppliers, review qualification and acceptance data, and drive corrective action and/or second sourcing.
  • Author and execute acceptance and qualification test (ATP/QTP) campaigns per SMC-S-016; characterize component performance across the pressure and temperature envelope, feed results back into system requirements, and document results with clear test reports.
  • Support vehicle build, integration and test, and flight operations; disposition nonconformances and lead component issue or anomaly investigations to root cause and closure.
  • Represent components in design reviews, FMEAs, hazard analyses, and range safety interactions; contribute to the shared component knowledge base, qualification records, and lessons learned.
  • Mentor engineers and help set the component design and test standards used by the propulsion team.

Desired Qualifications

  • At least 10 years of spacecraft or launch vehicle fluid component experience, including clean-sheet design of a valve, regulator, or similar component through qualification and flight.
  • Experience with low-leakage, on-orbit propulsion components and with HTP, other strong oxidizers, or high-pressure gas systems.
  • Analysis skills for component design, including FEA of pressure-containing parts, 1D fluid network modeling, valve dynamics, and fatigue and fracture control.
  • Electromechanical and instrumentation fundamentals, including solenoid valve coil and driver interfaces, and pressure transducer and RTD calibration, excitation, and error budgets.
  • Supplier management for COTS and build-to-print aerospace components, including source selection, audits, and data package review.
  • Familiarity with AIAA S-080 and S-081 and AFSPCMAN 91-710 range safety requirements.
  • Knowledge of precision manufacturing and inspection for fluid hardware, including machining and deburring, welding, electropolish, precision cleaning, CMM, and NDE.
  • Experience standing up testing capabilities for propulsion components (development, qualification, and ATP), particularly in a high-cadence, high-component-throughput environment.
  • Prior experience leading a technical sub-discipline, formally or informally, and developing engineering standards within a propulsion organization.
  • Exceptional technical communication, precision, and clarity in specifications, test procedures, data package reviews, and engineering memos.

About the Company

Varda Space

In-orbit manufacturing with reentry return services

Varda Space Industries provides in-space manufacturing by operating production facilities in low Earth orbit and returning finished goods to Earth using reentry capsules. Clients send materials or designs to Varda’s in-orbit production line, where microgravity enables manufacturing processes not possible on Earth. After production, capsules re-enter Earth's atmosphere to deliver goods back to customers, supported by in-orbit equipment and reliable reentry systems. The company aims to make low Earth orbit accessible for multiple industries by building end-to-end space manufacturing infrastructure and industrializing orbit for commercial use.
