We are looking to add a
Senior Valve Design Engineer I to our team. If you enjoy working in a startup environment and have experience in the design of the valves for different pneumo-hydraulic systems, we would like to hear from you.
In this role, you will be responsible for driving design decisions, mentoring engineers, and ensuring our vehicle systems meet performance, reliability, and safety standards. The ideal candidate will have a strong background in CAD systems, CFD and FEA simulations, combined with hands-on experience in experimental development and testing of all types of valves (inc. cryogenic).
JOB DUTIES AND RESPONSIBILITIES- Design and develop a variety of valves, including pneumoactuated, electropneumatic, electrohydraulic check valves, throttles, and regulators.
- Own requirements definition, architecture trades, and system-level integration for assigned subsystems.
- Generate technical documentation, including reports, specifications, and contributions to PDRs and CDRs.
- Perform CFD and FEA analyses to evaluate performance parameters such as pressure drops, hydraulic characteristics and mechanical integrity under operating conditions.
- Develop and execute test programs, analyze experimental data, and apply findings to optimize designs.
- Collaborate across mechanical, aerospace, and controls engineering teams to deliver flight-ready hardware.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
- 4+ years of industry experience in aerospace propulsion systems or related areas.
- Hands-on proficiency in CAD tools (Siemens NX, SolidWorks)
- Strong expertise in Ansys CFX, Fluent, and Mechanical for simulation and analysis.
- Demonstrated expertise in structural or mechanical design for flight hardware.
- Experience in early-stage vehicle architecture and design trades.
- Strong analytical and problem-solving skills with high attention to detail.
- Excellent written and verbal communication skills.
PREFERRED EXPERIENCE- Master's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
- Prior experience designing cryogenic valves for liquid rocket engines or other rocket systems.
- Practical experience in test bench setup and performance diagnostics.
- Hands-on engineering (Full-stack: computer to wrench to broom)
- Geometric dimensioning and tolerancing (GD&T)
- Familiarity with aerospace safety and reliability practices.
- Experience in a start-up or rapid development environment.
