Other Engineering
Sunnyvale, CA, USA
Posted on Tuesday, January 31, 2023
The Company
Astra’s mission is to Improve Life on Earth from Space® by creating a healthier and more connected planet. Today, Astra offers one of the lowest cost-per-launch dedicated orbital launch services of any operational launch provider in the world, and one of the industry’s first flight-proven electric propulsion systems for satellites, Astra Spacecraft Engine™. Astra delivered its first commercial launch to low Earth orbit in 2021, making it the fastest company in history to reach this milestone, just five years after it was founded in 2016. Astra (NASDAQ: ASTR) was the first space launch company to be publicly traded on Nasdaq.
The Team
The space products engineering team is producing low-cost, reliable, highly efficient, Hall-effect thruster propulsion systems for modern satellites and spacecraft. Our thrusters will be used in Low Earth Orbit, Medium Earth Orbit, Geostationary Orbit, Lunar missions, and beyond. The team includes talented engineers who have designed and launched into orbit over 1,000 satellites over the course of their careers. Comprehensive design, prototype production, qualification, and acceptance tests are conducted within our Alameda, Mountain View and new Sunnyvale facilities.
The Opportunity
You will work with an interdisciplinary team of other mechanical engineers, propulsion engineers, machinists, electrical engineers, and technicians to bring designs to life. This position is for a Fluid Systems / Feed System Mechanical Design Engineer. New programs come in frequently. You will be a primary contributor on a team that develops new systems/modules and launches them into orbit.

How You'll Fulfill Your Mission

  • Design, Development and Qualification of high pressure and low pressure fluidic components: manifolds, valves, tanks, tubing
  • New development (clean-sheet design) of next generation in-space propulsion system components
  • Generate 3D models, fully dimensioned drawings, and interface control documents per ASME Y14.5 GD&T standards using Siemens NX CAD tool
  • Perform initial structural analyses in NX Simcenter / hand calculations and coordinate with System Analysis team
  • Perform fluidic analyses to determine pressures, flow rates, valve cycle counts, etc
  • Document & update testing procedures, test & analysis results, inspection reports, FMEAs, requirement documents, work instructions, etc.
  • Ensure best practices in our Product Data Management system including design documentation, process documentation, inspection, and quality control
  • Deliver efficient designs capable of high-volume production throughput
  • Conduct mechanical peer reviews of models and drawings
  • Set, implement, and maintain schedules and budgets to ensure project completion


  • You have 5+ years of professional experience in mechanical design and analysis using CAD & PLM tools (Siemens NX preferred)
  • You have experience with hands-on fabrication, assembly, and/or testing of fluidic components and aerospace hardware

  • You have strong mechanical engineering fundamentals
  • You can critically analyze problems and are excited by new design challenges
  • You are self-motivated and have excellent written and verbal communication skills

Desired Multipliers

  • You have 10+ years of professional experience in mechanical design
  • Experience with production tooling or product design in either prototype or volume environments
  • Familiarity with space systems
  • Experience with high pressure pneumatics/fluid management systems and designs including latch valves, piezo valves, and regulators
  • Critical thinking applied to root cause investigation and corrective actions
  • You have experience with structural FEA tools (NASTRAN preferred)
  • You have experience with thermal and CFD tools (Thermal Desktop and Star-CCM preferred)
  • Be comfortable working in a fast-paced, self-driven entrepreneurial workplace where you get your hands dirty working directly with hardware
