Full Job Posting

Key Responsibilities

  • GNC & Embedded Software Development
  • Design, implement, integrate, and verify mission-critical missile software, focusing heavily on GNC algorithms, autopilot loops, and flight control laws.
  • Translate complex mathematical flight dynamics models into high-performance, deterministic, real-time code.
  • Utilize Model-Based Design (MBD) frameworks (e.g., MATLAB/Simulink auto-coding) to transition control algorithms seamlessly into target hardware.
  • Hardware-in-the-Loop (HWIL) & Simulation Management
  • Architect, maintain, and expand HWIL test environments, integrating flight computers, inertial measurement units (IMUs), actuation systems, and sensor suites.
  • Plan and execute rigorous HWIL test campaigns to validate software performance against simulated aerodynamic threats, target profiles, and environmental disturbances.
  • Troubleshoot complex, multi-domain system failures spanning software logic, digital/analog signal interfaces, and physical hardware behavior.
  • Verification, Validation, & Accreditation (VV&A)
  • Lead VV&A activities for simulation environments, software-only test beds, and HWIL facilities to ensure high fidelity and traceability to system requirements.
  • Develop automated test scripts and regression suites to support continuous integration and rapid deployment of software updates.
  • Pre-Flight Support & Mission Planning
  • Collaborate with systems engineering and flight test teams to execute pre-flight activities, including missile flyout predictions, trajectory simulations, and safety analysis.
  • Define and optimize Restricted Operating Zones (ROZ), range safety limits, and mission scripts for live-fire or captive-carry tests.
  • Field Deployment & Discrepancy Resolution
  • Apply deep flight-dynamics and systems-level knowledge to root-cause analysis, anomaly investigation, and discrepancy resolution during test execution.
  • Deploy to remote test ranges, proving grounds, or integration facilities as required to support pre-test checkouts, launch operations, and post-flight data reduction.
  • Required Qualifications & Technical Stack
  • Experience: 10+ years of professional software engineering experience specifically within aerospace, defense, or missile systems.
  • Education: B.S., M.S., or Ph.D. in Computer Science, Aerospace Engineering, Electrical Engineering, or a related technical discipline.
  • Core Programming Languages: Advanced proficiency in C and C++ for real-time embedded environments; familiarity with Python or MATLAB for scripting and analysis.
  • Real-Time Operating Systems (RTOS): Experience developing safety-critical software on RTOS platforms (e.g., VxWorks, Linux with PREEMPT_RT).
  • Domain Knowledge: Strong working knowledge of flight dynamics, 6-DOF (Degrees of Freedom) simulation, aerodynamics, and control theory.
  • HWIL & Lab Equipment: Proven background managing HWIL labs using real-time simulation hardware (e.g., dSPACE, National Instruments PXI/CompactRIO, Speedgoat) and communication protocols (MIL-STD-1553, Ethernet/UDP, ARINC 429, RS-422).
  • Clearance: Must be eligible to obtain and maintain a Secret

Desired Qualifications

  • Experience with safety-critical software development standards (e.g., DO-178C or equivalent military standards).
  • Familiarity with Agile development workflows, configuration management tools (Git, SVN), and requirements traceability tools (DOORS, Jira).
  • Hands-on experience with sensor simulation or seeker-in-the-loop (SIL) testing.
  • Radiance Technologies is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or protected veteran status.
