About Radiant
Radiant is an El Segundo, CA-based company building the world's only mass-produced, transportable nuclear microreactors. The U.S. grid is under growing strain, with power demand accelerating, driving higher utility costs, rising carbon emissions, and interconnection backlogs. Radiant has a solution, transportable, on-site power. Our first reactor, Kaleidos, is 1 megawatt: small enough to be factory-built, transported by land, sea, or air, and deployed wherever power is needed. 1 MW can power 1000 homes for five years. Ship it back and we refuel for a 20 year operating life. We made energy a product that can be used for critical infrastructure like military bases, data centers, hospitals, and remote sites, as well as the commercial main street businesses that keep America running. Founded in 2020, Radiant is under contract to deliver power to the U.S. Army, Navy and Air Force and has signed pre-order agreements with Equinix, with deployments beginning in 2028.
About the Role
We are seeking a Staff Reactor Systems Engineer to own the technical integration of a first-of-a-kind reactor. With no operating predecessor to copy and no mature supply chain, you will be the person who holds the whole machine together, making sure hundreds of design decisions across nuclear physics, thermal-hydraulics, controls, structures, materials, fuel, and licensing add up to a reactor that works safely and is delivered to customers on time.
You will be the technical authority for how the pieces of Kaleidos fit together: translating top-level product and safety requirements into subsystem requirements, owning interfaces, and making sure the integrated system performs, is safe, and can be built, tested, and deployed repeatably.
As a staff-level engineer, you will work across every engineering discipline, resolve the hardest cross-system tradeoffs, and set the systems engineering practices the team uses as Kaleidos moves from first-of-a-kind builds to scaled production. You will be instrumental in unlocking commercialization of the first mass-produced nuclear reactor.
Responsibilities & Duties
Own the Kaleidos system architecture and serve as technical authority for integrated system performance, safety, and reliability.
Define and manage system budgets (e.g., thermal, mass, power, reactivity, and volume) and allocate margins across subsystems.
Own interface definitions and interface control documents between subsystems, including reactor core, primary loop, power conversion loop, shielding, controls, and structures.
Maintain the technical baseline (requirements, configuration, change control, risk registers, and documentation) using lightweight processes scaled to a fast-moving startup.
Identify cross-cutting risks early and drive them to resolution before they become safety or schedule problems.
Define the verification and validation strategy and partner with Test Engineering to turn requirements into test plans, success criteria, and acceptance tests.
Correlate analysis and test results against system requirements, and drive resolution of discrepancies.
Support safety-basis and licensing or regulatory documentation as needed.
Mentor engineers across the organization in systems thinking, requirements quality, and interface discipline.
Communicate system status, risks, and tradeoffs clearly to engineering and program leadership.
Required Qualifications & Skills
Bachelor’s degree in engineering, physics, or a related technical discipline from an accredited institution.
10+ years of professional engineering experience, including meaningful time in systems engineering, integration, testing, engineering operations, or technical leadership on complex hardware.
Demonstrated experience owning requirements and interfaces for a complex system from concept through build, test, and operation.
Experience leading system-level trade studies and making sound decisions with incomplete information.
Strong working knowledge across several relevant disciplines, such as thermal-fluids, mechanical, structural, power systems, or controls.
Experience with verification and validation, and with hazard and risk analysis methods (e.g., FMEA, FTA).
Demonstrated technical leadership across multidisciplinary teams without relying on formal authority.
Strong written and verbal communication, including producing clear technical documents and presenting to varied audiences.
Desired Qualifications & Skills
Knowledge of nuclear reactor design, reactor safety, or nuclear regulatory frameworks.
Experience with high-temperature systems, thermodynamic power cycles, or power generation systems.
Experience with configuration management and change control for hardware programs.
Experience transitioning hardware from development builds to repeatable production.
Startup or fast-paced hardware development experience.

Tips for Your Staff Engineer Manager Job Search
Show scope and headcount on your resume
Staff engineer manager roles expect clear evidence of technical leadership at scale. Quantify the size of the engineering teams you led, the systems you owned, and the cross-functional initiatives you drove, so reviewers can assess scope without guessing.
Distinguish technical depth from management breadth
Many staff engineer manager postings screen out candidates whose resumes read as either pure IC or pure people manager. Make both sides explicit: highlight architectural decisions you owned alongside headcount, performance cycles, and hiring outcomes you drove.
Target roles that name your stack explicitly
Job descriptions that list your exact infrastructure, language, or platform signal a team that already knows what they need. Filter openings by the systems you know best rather than applying broadly, and your technical fit will come through clearly in interviews.
Apply early to roles that fit
Migrate Mate lists staff engineer manager openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Prepare a system design story for each role
Interviews for this role almost always include a staff-level system design round plus a leadership scenario round. Prepare a single end-to-end example that shows architectural tradeoffs you made, how you got team buy-in, and what you would do differently now.
Negotiate the technical charter, not just the title
When you receive an offer, ask directly what the team's technical roadmap looks like for the next year and who owns architectural decisions. The scope of your actual influence matters as much as compensation when evaluating whether the role is the right fit.
Staff Engineer Manager Jobs: Frequently Asked Questions
Which companies are hiring the most staff engineer managers?
The most active employers for staff engineer managers right now are Lockheed Martin, Northrop Grumman, and Google, and the most openings are in California, Texas, and New York, based on current listings on Migrate Mate as of November 2026. Demand is strongest at large technology companies and high-growth startups scaling their platform and infrastructure organizations.
How many staff engineer manager jobs are remote?
About 60% of staff engineer manager openings are fully remote or hybrid as of November 2026, reflecting the distributed nature of modern engineering organizations. Platform engineering, infrastructure, and developer tooling sub-specializations tend to have the highest share of remote-eligible openings compared to roles with heavy on-site hardware or lab dependencies.
How do you become a staff engineer manager?
Most staff engineer managers move into the role by first reaching a senior or staff individual contributor level, demonstrating technical leadership on high-impact projects, and then taking on people management responsibilities, often starting with a small team. Building a record of mentoring engineers, leading architecture decisions, and partnering with product leadership strengthens a path into the role. Some organizations also promote strong engineering managers who invest in deepening their technical depth.
How do you get hired as a staff engineer manager with limited experience?
If your direct management experience is limited, focus applications on companies that promote staff-level individual contributors into hybrid technical leadership roles, where you can build management scope gradually. Highlight any informal leadership you have done: running design reviews, onboarding engineers, or leading cross-team initiatives. Smaller engineering organizations and growth-stage startups are more likely to hire candidates who are earlier in their management progression.
What does the staff engineer manager interview process look like?
Most processes include a recruiter screen, a hiring manager conversation focused on leadership philosophy and team scope, a technical system design round that tests architectural judgment at scale, a cross-functional or behavioral panel with product and senior engineering partners, and a final executive or senior leadership conversation. Some companies also include a written take-home assessing how you would approach a real organizational or technical challenge relevant to their current roadmap.
