About The Position

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. 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 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 Effects Engineer will proactively identify radiation driven risks, manage component level and system level effects analyses, and partner with program management, design engineering, and suppliers to embed radiation resilience throughout the development lifecycle.

Requirements

• 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 TID, SEE, SEU, SEL, SET, DDD, and dose rate effects on microelectronics.
• Proficiency in radiation modeling tools (e.g., GEANT4, MCNP, FASTRAD) and device level analysis methodologies.
• Demonstrated experience developing and executing radiation test campaigns at accredited facilities.
• Strong communication, leadership, and cross-functional collaboration skills.

Nice To Haves

• Experience with spaceborne electronics, rad hard design, FPGA radiation characterization, or microelectronics reliability.
• Advanced degree (MS or PhD) in radiation physics, microelectronics 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.

Responsibilities

• Define product radiation environments (TID, SEE, displacement damage, dose rate, etc.) and perform system/component level effects assessments.
• Model radiation transport and shielding effectiveness to inform system architecture decisions.
