Responsibilities
- Design, develop, test, and maintain firmware for reactor instrumentation, control, monitoring, and electrical support systems.
- Develop embedded software for microcontrollers, embedded processors, and real-time hardware platforms.
- Bring up new hardware, debug board-level issues, and validate firmware with laboratory equipment including oscilloscopes, logic analyzers, multimeters, and power supplies.
- Implement SPI, I2C, UART, CAN, Ethernet, RS-485, and similar communication interfaces.
- Develop sensor acquisition, actuator control, telemetry, diagnostics, fault detection, and system health-monitoring functionality.
- Collaborate with electrical engineers on schematics, board design reviews, signal integrity, interface definitions, and hardware/software requirements.
- Support hardware-in-the-loop testing, automated test frameworks, data acquisition systems, and integration campaigns.
- Create firmware test plans, verification procedures, and documentation for configuration-controlled releases.
- Analyze failure modes, define safe states, and implement embedded fault-handling logic.
- Drive root-cause investigations for firmware, electrical, and integration issues through bench and system-level debugging.
Requirements
- Bachelor’s degree in Computer Science, Computer Engineering, Software Engineering, or a related technical field.
- At least two years of production software development experience in C, C++, Python, Rust, or similar languages for hardware-integrated, distributed, embedded, robotics, aerospace, automotive, industrial, or mission-critical systems.
- Experience developing multi-threaded or multi-process systems involving IPC, networking, message passing, or publish/subscribe architectures.
- Experience integrating software with sensors, controllers, data acquisition systems, power supplies, embedded systems, or other hardware-facing interfaces.
- Strong debugging skills across software, hardware, and system-integration boundaries.
- Ability to design software interfaces, data models, state machines, and testable system behaviors.
- Preferred experience with real-time systems, RTOS-based development, bare-metal firmware, or safety-critical embedded software.
- Preferred experience with hardware bring-up, board-level debugging, root-cause analysis, firmware validation, sensors, actuators, power electronics, control systems, data acquisition, or telemetry systems.
- Preferred familiarity with bootloaders, firmware update mechanisms, device drivers, low-level peripherals, embedded communication stacks, and configuration-controlled systems.
- Preferred familiarity with safety-critical standards and practices including IEEE, IEC, DO-178C, DO-254, IEC 61508, ISO 26262, and DOE nuclear standards.
- Preferred experience contributing to design reviews, hazard analyses, verification plans, qualification documentation, hardware-in-the-loop testing, automated test frameworks, simulation environments, or embedded continuous integration.
- Ability to take ownership of ambiguous embedded-systems problems and drive them to closure.
- Applicants must meet applicable ITAR requirements or be eligible to obtain required U.S. Department of State authorizations.
Benefits
- Work focuses on first-of-a-kind microreactor technology for terrestrial, underwater, and space applications.
- Collaborative work across electrical, controls, reactor software, safety, test, systems, and licensing teams.
- In-person collaboration is emphasized, with travel to meet customers, users, or stakeholders when needed.
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.
