Spacecraft, NX Administrator

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge.

For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles.

Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more.

We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet.

Apex is building spacecraft at scale, and our ability to move fast depends on a world-class design environment. We’re looking for a CAD Systems Engineer who can own, elevate, and continually improve our Siemens NX ecosystem so our mechanical, avionics, and manufacturing teams can iterate quickly and reliably.

• Own Apex’s Siemens NX environment, ensuring it remains stable, performant, and optimized for rapid hardware development

• Define and maintain modeling standards, drafting conventions, customer defaults, and attribute requirements that drive high-quality CAD data

• Expand automated checks (Check-Mate, NX Open tools, etc.) to enforce consistency and reduce downstream rework across design and manufacturing

• Act as the go-to expert for engineers across mechanical, MEOP, avionics, and manufacturing to troubleshoot complex NX issues (assembly performance, WAVE links, translations, data handoff, etc.)

• Develop and deliver onboarding, training, and best-practice playbooks to accelerate user adoption and proficiency

• Partner closely with designers to understand real pain points and translate them into system improvements

• Collaborate with our Teamcenter admin to strengthen and scale a fully managed NX environment

• Ensure seamless integration between NX, Teamcenter, ERP, and MES to support accurate BOMs and manufacturing readiness

• Continuously re-evaluate and redesign CAD processes to remove friction, automate repetitive tasks, and unlock new capabilities across the product lifecycle

• Bachelor’s degree in engineering, computer science, or related field (or equivalent experience)

• 5+ years of hands‑on Siemens NX experience (implementation, configuration, administration, troubleshooting)

• Strong background supporting NX in Teamcenter‑managed environments

• Familiarity with aerospace‑specific modules and large, complex assemblies

• Demonstrated ability to train, mentor, and enable CAD users

• Proficiency in scripting/automation (NX Open, Python, ITK, or similar)

• Excellent communication and problem‑solving skills

• Ability to translate user pain points into scalable, maintainable system solutions

• Comfortable operating in a fast‑paced, highly iterative environment

Apex believes in creating a work environment that you look forward to embracing every day. Our employees love working at Apex, and we want you to love it too. We're a fast‑growing startup backed by $200M in Series D funding, and we invest heavily in our people from day one.
