Full Job Description
On the Automation and Control Engineering (ACE) team, you will design, build, and operate the software that connects our automated factory, test facilities, and launch systems. ACE is responsible for the full stack-from the central platform down to the device-level software running on controllers and equipment-and your work will directly shape how Terran R is built, tested, and flown.
  • * Own features end-to-end across the software development lifecycle: from problem framing and architecture through implementation, test, deployment, and operation
  • Build and maintain the platform services (real-time data pipelines, orchestration, UI, alerting), automation tooling and languages, and device-level software used by teams across the company to control and monitor real hardware
  • Partner directly with hardware, test, manufacturing, and launch teams to design, instrument, and continuously improve automation and control systems that are safe, observable, and resilient in production environments

About You:
  • You have 7+ years of experience in systems programming (C++ or Rust) and/or programming language implementation, with strong fundamentals in compilers, interpreters, or virtual machines
  • You have built or extended domain-specific languages or execution engines for hardware automation, scientific computation, trading, or other real-time domains where correctness, latency, and memory footprint matter
  • You are comfortable designing fast, low-allocation code paths and reasoning about performance in terms of cache behavior, allocation patterns, and data layout
  • You are excited to work on a proprietary language used for live hardware control and calculations, and to collaborate closely with users to evolve the language and runtime in a safety-critical context

Nice to haves but not required:
  • Academic or industry background in compilers, static analysis, formal methods, or programming languages research
  • Experience implementing type systems, bytecode interpreters, JITs, or code generation pipelines optimized for low latency and small memory footprints
  • Experience building scriptable automation frameworks or configuration/DSL layers on top of C++/Rust systems used to orchestrate hardware, tests, or complex workflows
  • Familiarity with real-time scheduling, concurrency models, and fault-tolerance techniques used when a language or runtime is responsible for controlling physical equipment


At Relativity Space, we are committed to transparency and fairness in our compensation practices. Actual compensation will be determined based on experience, qualifications, and other job-related factors.

Compensation is only one part of our total rewards package. Relativity Space offers competitive salary and equity, a generous PTO and sick leave policy, parental leave, an annual learning and development stipend, and more! To see some of the benefits & perks we offer, please visit here.
