Senior Manager, Embedded Systems Engineering

About the role

Radiant is seeking a Senior Manager of Embedded Engineering to lead the embedded software engineering team through the critical path to commercialization, planning and executing the embedded software architecture for I&C systems with a direct line to Kaleidos' 2028 deployment target. You will build and develop a high-performing team, manage cross-functional stakeholder relationships, and own execution across the full program lifecycle as we move from development into commercial readiness.

The ideal candidate is a proven engineering leader who can operate at the intersection of people management, technical strategy, and organizational influence in an ambiguous early-stage environment. You will have the opportunity to shape the embedded software foundation of the first commercialized portable nuclear microreactor, technology that will redefine how the world accesses clean, reliable power.

Responsibilities

• Build, grow, and manage a team of embedded engineers, owning hiring, performance, career development, and team culture.
• Partner with embedded technical leads on embedded software architectural decisions, testing frameworks, validation methodology, documentation standards, establishing patterns, and safety requirements.
• Manage cross-functional stakeholder relationships with electrical, controls, hardware, and executive leadership, aligning on priorities, interfaces, and constraints.
• Own program execution across the embedded engineering lifecycle, setting team expectations, managing delivery milestones, and ensuring accountability from architecture through field implementation.

Requirements

• Bachelor's degree in computer engineering, computer science, electrical engineering, or a related field.
• 8+ years of industry experience in embedded software, including significant ownership of system-level architecture decisions, real-time operating systems, and low-level programming.
• 3+ years of engineering management experience, including hiring, performance management, and team development.
• Deep proficiency in embedded C/C++.
• Track record of translating technical strategy into team execution, setting priorities, removing blockers, and holding the team accountable for rapid delivery.
• Strong communicator who can represent the embedded team's work and needs clearly to non-technical and executive audiences.

Qualifications

• Masters degree or higher in computer engineering, computer science, electrical engineering, or a related field.
• 5+ years of engineering management experience, including hiring, performance management, and team development.
• Experience leading teams working with RTOS and bare metal applications.
• Experience overseeing Simulink Autocode C++ export and integration in a production context.
• Experience managing large, multi-target embedded builds using CMake.
• Ability to engage at the hardware/software boundary, proficient in reading schematics and guiding hardware/software debug efforts.
• Experience in safety-critical or high-reliability domains (aerospace, defense, medical, nuclear, or industrial).
