Los Angeles, CA, USAEntry Level / Mid Level
Base Salary
$120k - $160k/yr
Responsibilities
- Develop reactor software for data acquisition, telemetry processing, command handling, state management, fault response, operator interaction, and automated test environments.
- Own features end to end from test specifications and interface definitions through implementation, review, integration, and documentation.
- Build consistent controls and interfaces for real instruments and in-memory simulations across simulation, bench, HIL/HITL, and reactor environments.
- Implement timeline scheduling, event and gate handling, mode transitions, command validation, command feedback, and telemetry streaming.
- Create software interfaces for hardware adapters, telemetry sinks, DAQs, sensors, controllers, operator tools, and external data systems.
- Implement telemetry validation and quality states including valid, invalid, stale, unavailable, and suspect.
- Develop fault detection, classification, containment, recovery, reset, diagnostics, logging, and observability behavior.
- Write automated tests for real system behavior and hardware-facing workflows where practical.
- Support simulation, HIL/HITL, hardware bring-up, integrated reactor testing, and software-hardware debugging.
- Collaborate on interface control documents, communication schemas, data dictionaries, integration test plans, design reviews, code reviews, test readiness reviews, and root-cause investigations.
Requirements
- A bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, Software Engineering, or a related technical field is required.
- Software Engineer I requires 0-2 years of experience, while Software Engineer II requires 2-5 years of experience.
- Experience developing maintainable production or project software for hardware-integrated, distributed, embedded, robotics, aerospace, automotive, industrial, or mission-critical systems is required.
- Strong Python 3 fundamentals, including typed code, structured data models, exceptions, testing, and idiomatic code organization, are required.
- Knowledge of data structures, object-oriented design, and readable, testable, maintainable software interfaces is required.
- Familiarity with concurrent, asynchronous, or multi-process patterns such as asyncio, threads, multiprocessing, event loops, IPC, networking, or message passing is required.
- Experience integrating software with sensors, controllers, DAQs, instruments, power supplies, embedded systems, simulations, or other hardware-facing interfaces is required.
- Ability to design data models, state machines, command flows, and testable system behaviors is required.
- Strong debugging skills across software, hardware, and system-integration boundaries are required.
- Experience with Git, pull requests, code review, and technical documentation is required.
- U.S. person status or eligibility to obtain required export authorizations is required.
- Preferred experience includes hardware or instrumentation software, event-driven command-and-control systems, telemetry pipelines, state-machine architectures, fault-aware behavior, messaging and networking technologies, simulation, HIL, fault injection, test automation, continuous integration, Linux, containerized environments, modern Python tooling, C, C++, Rust, embedded interfaces, binary data formats, and safety- or mission-critical systems.
Benefits
- Base salary is listed by level: Software Engineer I $120k-$135k and Software Engineer II $135k-$160k.
- The role includes hands-on work across simulation, bench, hardware-in-the-loop, and full-scale reactor environments.
- Employees collaborate in person across software, electrical, controls, embedded systems, safety, test, and systems teams; travel to meet stakeholders may occur.
About Antares
Energy abundance unlocks progress. It powers missions, grows economies, strengthens national security, and expands what’s possible on Earth and beyond. But in the places where power is most critical, it’s often the hardest to deliver. That’s the problem we’re solving. At Antares, we’re building compact nuclear microreactors to deliver reliable, mobile energy where it’s needed most: remote military bases, austere industrial sites, and, one day, deep space and underwater missions. The U.S. nuclear industry hasn’t seen true momentum in decades. We’re moving it forward with urgency, humility, and a commitment to building what’s needed now. Our team includes engineers and operators from SpaceX, Relativity Space, Ursa Major, the White House, MIT, Rigetti Computing, and the U.S. Air Force. Backed by over $600M from top-tier investors, we’re focused on shipping hardware, not hypotheticals.
