In this role, you will be the lead hands-on technical practitioner across mechanical hardware, real-time embedded software, computer engineering architectures, Guidance, Navigation, and Control (GNC) algorithms, and Control Actuation Systems (CAS).\nWorking under the direction of the Program Chief Engineer (who holds final airworthiness and system sign-off authority), you will serve as the primary hands-on technical architect and lead developer-translating top-level program requirements into production-ready flight code, integrated actuator mechanisms, low-latency bus architectures, and high-fidelity HWIL testbeds.\nKey Responsibilities\n1. Multidisciplinary Lead Development & Prototyping\nAct as the lead hands-on developer across mechanical structures, embedded software, onboard computer architectures, GNC algorithms, and CAS actuation subsystems.\nFormulate, model, and execute multi-domain trade studies-balancing mechanical mass/inertia constraints, aerothermal loading, computational throughput, and control loop latency for presentation to the Chief Engineer.\nDraft system and subsystem technical specifications, Interface Control Documents (ICDs), and qualification plans for review and approval by the Chief Engineer.\n2. Control Actuation Systems (CAS) & Mechanical Implementation\nLead the hands-on engineering, dynamic modeling, and laboratory integration of high-speed Control Actuation Systems (electromechanical, hydraulic, or cold-gas thrusters).\nAnalyze fin/nozzle dynamic response, thermal limits, high-torque gearbox compliance, and motor drive performance under extreme G-force and aerodynamic load environments.\nTroubleshoot complex physical-electrical-hydraulic failure modes, structural resonances, non-linearities (backlash, hysteresis), and mechanical compliance issues.\n3. GNC Algorithm Development & Flight Code Generation\nLead the formulation, numerical simulation, and code implementation of advanced GNC algorithms, autopilot loops, Kalman filters, and trajectory optimization routines.\nTranslate complex 6-DOF (Degrees of Freedom) flight dynamics models into deterministic, real-time C/C++ code executed on onboard flight processors.\nEvaluate missile maneuvering performance, dynamic stability, and guidance accuracy across subsonic through hypersonic regimes.\n4. Software Architecture & Embedded Computer Engineering\nArchitect low-level embedded software frameworks for onboard flight computers, processing units (FPGA, DSP, SoC), and real-time communication buses.\nImplement performance-optimized C/C++ code, managing RTOS task prioritization, memory allocation, multi-core synchronization, and interrupt service routines.\nConduct hardware/software co-design to ensure seamless interface timing between flight computers, Inertial Measurement Units (IMUs), seekers, and CAS drive electronics.\n5. HWIL Development, Testing, & Root-Cause Analysis\nDesign, build, and maintain Hardware-in-the-Loop (HWIL) and Processor-in-the-Loop (PIL) simulation setups to test flight software against physical actuators and hardware under test.\nImplement Verification, Validation, and Accreditation (VV&A) procedures for simulation tools and test beds.\nDeploy to remote proving grounds and flight test ranges to support pre-flight checkouts, real-time telemetry decoding, and post-flight anomaly root-cause analysis for the Chief Engineer.\nRequired Qualifications & Technical Background\nEducation: B.S. with 25+ years, M.S. with 15+ years, or Ph.D. with 10+ years of hands-on experience in Aerospace, Mechanical, Electrical, Computer Engineering, or Computer Science.\nHands-on Development Track Record: Demonstrated experience as a lead technical developer or primary architect on at least one guided weapon, missile, or interceptor program from initial code/cad through flight test.\nMechanical & CAS Skills:Practical expertise in missile mechanical structures, aerothermal heating considerations, structural dynamics, and electromechanical actuator (EMA/CAS) integration.\n\nGNC & Flight Mechanics:Advanced capability in control theory, 6-DOF modeling, trajectory design, and guidance implementation.\n\n Software & Embedded Systems:Advanced proficiency in C / C++, Python, and MATLAB / Simulink (including automated flight code generation via Embedded Coder).\nHands-on RTOS development (VxWorks, Linux PREEMPT_RT, Green Hills INTEGRITY) and embedded bus integration (MIL-STD-1553, ARINC 429, Ethernet/UDP, PCIe, CAN, SPI, RS-422).\n\nSecurity Clearance: Must possess an active US DoW Secret security clearance\nDesired Qualifications\nWorking knowledge of MIL-STD-882 (System Safety) or DO-178C software development practices.\nExperience interfacing directly with Chief Engineers, IPT Leads, and DoW customer technical teams during design reviews (PDR/CDR).\nRadiance 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.","description_format":"text","description_chars":5289,"description_truncated":false,"requirements":{"experience_years_min":15,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["National Security","Engineering Services"],"lifecycle":[{"event":"open","at":"2026-10-25T02:40:59Z"}],"visa":[],"liveness":{"score":99,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.993,"p_room":1,"age_days":4,"expected_fill_days":34,"reasons":["conf:3","urgency","velocity","win:early"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/radiance-technologies-subject-matter-expert-sme-lead-developer","json_url":"https://alion.io/job/radiance-technologies-subject-matter-expert-sme-lead-developer.json","meta":{"generated_at":"2026-10-28T04:52:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6361,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":1845002},"rest":"https://alion.io/mcp/rest/get_company?id=1845002"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fradiance-technologies-subject-matter-expert-sme-lead-developer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fradiance-technologies-subject-matter-expert-sme-lead-developer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fradiance-technologies-subject-matter-expert-sme-lead-developer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/radiance-technologies-subject-matter-expert-sme-lead-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fradiance-technologies-subject-matter-expert-sme-lead-developer"}]}
