SR. MECHANICAL ENGINEER (DIRECT TO CELL)

SpaceX is designing a revolutionary new satellite to deliver seamless cellular connectivity worldwide via the Starlink constellation. This satellite will feature SpaceX’s largest-ever phased array antenna – designed to launch on Starship and for high-rate production to enable rapid rollout of global coverage. As a Mechanical Engineer on the Direct to Cell team, you’ll be required to tackle a wide range of novel engineering challenges at the intersection of mechanical, electrical, thermal, and antenna design constraints. In this role, you will be given a large amount ownership scope and an unparalleled opportunity to influence the future of the Direct to Cell program alongside a small team of passionate, top-tier engineers. Your work will span the full hardware lifecycle, from defining design requirements and system architecture to detailed design, analysis, qualification testing, production process development, and on-orbit support.

Responsibilities

  • Design, prototype, test, and qualify mechanical assemblies in iterative cycles to mature the Direct to Cell system.
  • Collaborate with cross-functional teams to create innovative payload electromechanical interfaces, spanning scales from the full satellite and antenna array to intricate PCB-level details.
  • Partner with internal and external manufacturing teams to scale new projects and technologies into high-volume, cost-effective production.
  • Conduct mechanical analysis at an appropriate level of fidelity (from hand calculations to finite element analysis) to support design trades, optimizations, and decision-making for novel mechanical systems.
  • Demonstrate extreme ownership of the execution and outcomes of design, development, testing, and launch milestones across the hardware lifecycle.

Basic Qualifications

  • Bachelor’s degree in an engineering discipline.
  • 5 years of experience using computer aided drafting (CAD) software (e.g. NX, CATIA, or ProE).
  • 5 years of experience with finite element analysis (FEA).

Preferred Skills/Experience

  • Experience working the entire development lifecycle (ideation/concept, design, analysis, prototyping, testing, manufacturing/production, and operations/maintenance).
  • 5 years of engineering experience working in complex, multi-disciplinary design and build projects.
  • Strong experience using CAD for both modeling and GD&T compliant manufacturing drawings.
  • Project and/or research-based experience conducting detailed thermal or mechanical analysis with FEA software (e.g. ANSYS, NASTRAN, ABAQUS, etc.).
  • Experience in mechatronics or other cross disciplinary combination of mechanical, electrical, and software skill sets.
  • Prior programming experience (Python, Matlab, C/C , Excel, etc.).
  • Basic understanding of electrical engineering fundamentals.
  • Interest in working at a nimble engineering organization that requires a scrappy, entrepreneurial approach to accomplish tasks within time & budget constraints.
  • Strong interpersonal and collaborative skills with an enthusiasm for problem-solving.

Additional Requirements

  • Ability to work extended hours and weekends as necessary to support critical milestones
