The Company

Astra's mission is to improve life on Earth from space by creating a healthier and more connected planet. Astra delivered its first commercial payload into Earth orbit in 2021, making it the fastest company in history to reach this milestone, just five years after being founded in 2016. By achieving monthly, weekly, then daily launches, we'll create the infrastructure services our customers need in space to build a healthier and more connected planet. If you're excited by a sense of possibility, the chance to innovate, and make a difference here on Earth, we think you should work here too.

The Team

The Systems Analysis team analyzes designs, works with design teams to improve design integrity, works with architecture teams to define requirements & standards, develops custom tools & codes, provides support & training, continuously improves our wide variety of products including the launch vehicle, spacecraft, launcher and propulsion systems to improve life on earth from space. The team is comprised of talented engineers collaboratively working through the challenges of launch & space systems development.

All forms of rocket & spacecraft development, qualification and acceptance tests are conducted in-house in our rapidly expanding facilities.

The Opportunity 

You will be our resident expert developing structural simulations, performing vehicle dynamics analysis, conducting structural tests (quasi-static, acoustics, shock, and vibration), performing advanced linear and nonlinear analyses, flight data analysis and predictions, improving test and analysis methodologies, building post-processing tools, building custom codes, & supporting designer engineers. You will be our point of contact for contracted analyses, and we will rely on you to set the standards for analyses techniques.

How You'll Fulfill Your Mission

  • Build finite element models and/or statistical energy analysis models for use in dynamic simulations.
  • Perform various structural analyses required to design the product including modal, static, random vibration, transient shock, acoustic analysis.
  • Perform parametric design studies to improve design concepts & efficiency.
  • Generate test requirements (static and dynamic) as well as the overall qualification and acceptance test approach for avionics components and secondary structures.
  • Develop standards to be used on FEA; define tools & acceptable post-processing methods.
  • Execute testing (quasi-static, sine & random vibration, shock, and acoustic) from start-to-finish.
  • Analyze acceleration and pressure time history data from tests & flights for use in structural analysis.
  • Provide vehicle loads, dynamic design guidelines and requirements to mechanical designers in early phases of hardware development.
  • Be a key part of the engineering, analysis, and test cycle by interfacing with design and test engineers to perform analyses, conduct structural tests, interpret results, and iterate to solutions.
  • Help guide the selection and location of instrumentation for refining loads models based on flight and test environments.
  • Improve the existing analytical capabilities, processes, and tools
  • Develop and document the load cases and results in a clear, concise manner so that they can correlate to past analyses as well as inform future analyses.

Qualifications

  • Strong experience in aerospace, aircraft, or automotive loads and dynamics analysis
  • You are an expert in finite element modeling (NASTRAN preferred)
  • You are an expert in structural analysis and test, including a fundamental understanding of strength, stability and fatigue failure mechanisms
  • You have demonstrated ability of working with design engineers symbiotically to create efficient designs that satisfy broad requirements
  • You have demonstrated ability to validate FEA models with test data
  • You have a strong understanding of commonly used materials & their mechanical/thermal behavior
  • You are comfortable with data processing tools ranging from Excel to custom scripts built with VBA, Python, MATLAB, etc.
  • You own analysis projects from beginning to end, with minimal oversight
  • You’re excited to work in a fast-paced, self-driven, iterative startup environment
  • Self-motivated with strong organizational, communication and documentation skills
  • You have a Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Acoustics or related technical discipline

Desired Multipliers

  • Master’s degree in Mechanical Engineering, Aerospace Engineering, Acoustics or related technical discipline
  • You have experience in coupled loads analysis or random response analysis
  • You are knowledgeable in application of vibration/shock specification and test methodologies
  • Experience in modal testing and analysis
  • You have conducted random and quasi-static electro-dynamic vibration tests; measured and analyzed time histories of the system response
  • You have CFD & thermal analysis experience

ITAR Requirements: This position requires compliance with U.S. Government space technology  trade restrictions, specifically the International Trafficking in Arms Regulations (ITAR), Export Administration Regulations (EAR) and additional regulations governing satellite, launch vehicle, missile, and other related technologies.  All jobs restricted by these regulations will be contingent upon the applicant’s status as a documented U.S. Person or their ability to receive a trade license from the cognizant government agency; in addition to any required company background checks and in compliance with applicable U.S. and California laws.  Similarly, positions requiring the ability to work on government contracts or a security clearance are also contingent upon the applicants ability to receive the appropriate clearance and be allowed to work on U.S. government contracts.

You do not need to match every listed expectation to apply for this position. Here at Astra, we know that diverse perspectives foster the innovation we need to be successful, and we are committed to building a team that encompasses a variety of backgrounds, experiences, and skills.

San Francisco Applicants: Astra will consider applicants with arrest and conviction records (criminal histories) in a manner consistent with the San Francisco Fair Chance Ordinance.
