If you are looking for hands‑on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward‑thinking individuals to join our team.

We are seeking a highly motivated Turbomachinery Engineer II to support the design, development, and testing of next‑generation rocket propulsion systems. In this role, you will be responsible for creating and optimizing critical turbopump hardware from initial concept through flight‑ready implementation. Working closely with multidisciplinary engineering and manufacturing teams, you will contribute to the rapid development of high‑performance propulsion technologies in a fast‑paced environment where hands‑on problem solving, technical rigor, and continuous innovation are essential to mission success.

Job Duties and Responsibilities

• Design and develop a variety of turbopump parts, including cryogenics pumps, turbines and seals. Create models and drawings of parts and assemblies. Perform calculations and analyses with team support.
• Own requirements definition, architecture trades, and system‑level integration for assigned subsystems.
• Create schematics and document processes.
• Perform CFD and FEA analyses to evaluate performance parameters such as efficiency, head curves and mechanical integrity under operating conditions.
• Work with manufacturing team to create finished turbomachinery parts. Support parts through 3‑d printing, machining, post processing, and inspection. Incorporate feedback to improve design for manufacturing.
• 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.
• 3+ years of experience in aerospace propulsion systems or related areas.
• Hands‑on proficiency in CAD tools (Siemens NX, SolidWorks).
• 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.
• Willing to make mistakes, take responsibilities, work independently and be transparent about your work.
• Excellent written and verbal communication skills.

Preferred Experience

• Prior experience designing turbopump parts, including cryogenic pumps, turbines and seals, 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.
