Sr. Tooling Designer, Injection Molding

Bastrop, TX
Full Time On-site

SpaceX is leveraging its experience in building rockets and spacecraft to deploy Starlink, the world's most advanced broadband internet system. Starlink is the world's largest satellite constellation and is providing fast, reliable internet to 10M+ users worldwide. We design, build, test, and operate all parts of the system - thousands of satellites, consumer receivers that allow users to connect within minutes of unboxing, and the software that brings it all together. We've only begun to scratch the surface of Starlink's potential global impact. As we continue to upgrade and expand the constellation, we're looking for best-in-class engineers to join the team.

As part of the materials engineering team, you will provide expertise and capabilities to developing processes for the production of plastic injection molds. You will make an impact on SpaceX's Starlink product components alongside a strong group of mechanical and process engineers. The goal of the team is to develop new manufacturing methods, commission equipment and qualify processes to be introduced into production.

RESPONSIBILITIES:

  • Own parting line development and surfacing of in-house molds and components
  • Responsible for all design for manufacturability (DFM) studies on plastic injection molded components
  • Own and manage the feasibility and surfacing of critical mold components
  • Interpret mold filling simulations and cooling analyses to drive feasibility and tool design
  • Design tools to be manufactured in-house
  • Support external tool designs and attend mold trials at vendor shops
  • Ensure designs are safe, effective, and manufacturable

BASIC QUALIFICATIONS:

  • 5+ years of professional experience as a designer
  • 3+ years of feasibility and mold flow analysis
  • Experience with Siemens NX
  • Experience with designing injection molds

PREFERRED SKILLS AND EXPERIENCE:

  • Extensive knowledge of standard mold components
  • Experience with hot runner systems
  • Knowledge of mold flow analysis
  • Experience with multi-shot, compression and other tooling
  • Knowledge of drafting practices and principles
  • Understanding of strength of materials, automation, part assembly and process control techniques

ADDITIONAL REQUIREMENTS:

  • Must be willing to work extended hours and weekends as needed
  • Must be willing to travel (up to 25%) to external suppliers and other SpaceX facilities

ITAR REQUIREMENTS:

  • To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C.

About SpaceX

SpaceX

SpaceX is one of the most influential aerospace companies in the world, transforming space launch, satellite communications, and deep-space transportation. Founded by Elon Musk, SpaceX designs and manufactures advanced rockets and spacecraft, including Falcon 9, Falcon Heavy, and Starship, alongside the Dragon spacecraft and the Starlink satellite internet constellation. The company plays a major role in U.S. space access, national security launch capabilities, and commercial space infrastructure.

For job seekers, SpaceX offers opportunities across some of the most demanding engineering disciplines in the industry, including aerospace engineering, propulsion, software development, avionics, manufacturing, robotics, materials science, and mission operations. The company is especially attractive to engineers, technicians, and builders who want to work in a high-intensity environment focused on rapid iteration, vertical integration, and hands-on hardware development at scale.

Unlike traditional aerospace contractors that rely heavily on long development cycles, SpaceX operates with a fast-paced, vertically integrated engineering culture where teams design, build, test, and fly systems in rapid succession. Employees often work directly on flight hardware and production systems, contributing to programs that routinely push the boundaries of reusability, launch frequency, and cost reduction in space access.

As global demand for satellite communications, space infrastructure, and national security launch services continues to grow, SpaceX remains one of the most important employers in aerospace and defense-adjacent technology. For professionals seeking a highly challenging, mission-driven career at the cutting edge of spaceflight and advanced engineering, SpaceX stands out as one of the most ambitious and impactful companies in the world.
