Principal Radiation Effects Engineer

Position Title: Principal Radiation Effects Engineer Requisition ID: 1813 Position Location: Fairfax, VA / Sterling, VA / Littleton, CO Position Reports To: Engineering Vice President Supervises Others: No At Trident Systems Space Electronic Systems (SES) division, we believe in the power of using strong engineering principles to drive innovation and solve complex problems. We foster a culture of rigorous engineering and continuous improvement, leveraging the full knowledge of our organization through collaborative product development processes that include design and peer reviews. We combine our expertise in space electronics with right-sized development processes to create innovative, high-performance space-based electronic systems that meet our customers' evolving needs. We are a mission partner supporting DoD, Intelligence Community, and Civil space customers. We develop complex, radiation effects mitigated, designs that balance competing requirements in modern space programs, delivering cutting-edge solutions that enable our customers to achieve more in space. Position Summary The Principal Radiation Effects Engineer will serve as the technical authority for radiation environment definition, analysis, mitigation, and verification across advanced aerospace and defense programs. As a senior member of the engineering organization, this individual will lead radiation effects strategy for complex, integrated electronic systems-spanning semiconductors, boards, sensors, avionics, and spaceborne platforms. The successful candidate will leverage deep expertise in radiation and solid-state physics, and microelectronics reliability to guide design teams, assess mission environments, define test approaches, and ensure hardware survivability. Acting as both a hands‑on engineer and a cross functional leader, the Principal Radiation Survivability Engineer will proactively identify radiation survivability driven risks, manage component and system level effects analyses, and partner with program management, design engineering, and suppliers to embed radiation resilience throughout the development lifecycle. Duties and Responsibilities The Principal Radiation Survivability Engineer ensures mission success by providing rigorous technical leadership in radiation characterization, modeling, test planning, and design compliance verification. Radiation Environment & Effects Analysis Define mission radiation environments spectra (e.g. trapped particles, solar activity, Galactic Cosmic Radiation (GCR), etc.) and perform component and system level effects assessments. Model radiation transport and shielding effectiveness to inform system architecture decisions. Perform worst‑case analysis, margin assessments, and susceptibility evaluations. Mitigation Strategy Development Recommend component selection, shielding strategies, circuit level hardening techniques, and system level architectural approaches. Guide electronic design teams on layout, redundancy, error detection/correction, derating, and other resilience mechanisms. Testing & Verification Leadership Develop radiation test plans, including TID/ELDRS, DDD/TNID, and SEE testing. Coordinate with external radiation test facilities and oversee execution and data analysis. Document results, maintain compliance evidence, and communicate performance impacts and required mitigations. Cross Functional Technical Leadership Partner with design engineering, suppliers, reliability teams, and program management to ensure radiation requirements are flowed down and met. Identify risks early, recommend corrective actions, and support variance resolution. Provide technical leadership reviews and serve as the subject matter expert during customer engagements. Required Qualifications Bachelor's degree in Electrical Engineering, Physics, Nuclear Engineering, or related discipline (or equivalent experience). Minimum 10 years of experience in radiation effects engineering for aerospace, space, or defense electronic systems. Deep technical knowledge of radiation effects for EEE parts and other related materials Proficiency in radiation modeling tools (e.g., CREME96, SPENVIS, R-GENTIC, SEAM4, GEANT4, MCNP, FASTRAD, etc.) and device level analysis methodologies. Demonstrated experience developing and executing radiation test campaigns at accredited facilities. Strong communication, leadership, and cross‑functional collaboration skills. Preferred Qualifications Experience with spaceborne electronics, rad hard design, FPGA radiation characterization, and/or EEE parts reliability. Advanced degree (MS or PhD) in radiation physics, EEE parts reliability, or related field. Experience guiding multidisciplinary engineering teams and mentoring junior radiation engineers. Familiarity with aerospace program lifecycles, requirements development, and mission environment definition.
