What we'd build
Five things we'd build for Radiant's talent team.
Four come straight from your intake. The fifth only works for a company building microreactors. We show companies and titles here; the names come back in the pull.
01
Know the week a past candidate is ready to hear from you.
From your intakeRun it this week
Your warmest pipeline is the people who said "not now". Load past candidates from Ashby once, and Crustdata watches each one for a new title, a new employer, a team change or a tenure mark. The Anduril outflow shows why timing matters: the median EE left after 18.5 months. We confirmed 243 electrical engineers at Anduril today. Of the 240 with a start date, 93 are already past that mark, and 13 reach two years between now and mid-January.
How it runs
- Pull past candidates' profile URLs from Ashby and enrich them once with
person_enrich.
- Watch every profile for job and title changes with
watch_create. A weekly check flags the tenure marks you pick: 18 months, two years, four.
- Each alert names the change and the reason to reach out now. Anyone already in process in Ashby is skipped.
Re-engagement stops being a calendar reminder. The list tells you who moved, and who's about to.

02
When a leader leaves, call the team they left.
Signal · leadership change
When leadership shifts, ICs start listening. Since July, 38 directors, heads, VPs and chief engineers left Anduril or SpaceX. Many ran hardware teams: propulsion, optical engineering, quality, production, air defense engineering. Two already went to nuclear, to Valar Atomics and Kairos Power. Each exit points at a team worth a call this month, and the new employer shows where the next wave may follow.
How it runs
- Watch director-and-above exits at the companies you hire from with
watch_create.
- For each exit, pull the engineers in that function who stayed, with
person_search on current company, function and title.
- Rank them against your open reqs in Claude, skip anyone already in Ashby, and draft the note.
You reach the team in the weeks after the change, while they're deciding whether to stay.

The rest run programs, operations, supply chain, security, finance and growth. Names come back in the pull.
03
See which nuclear peers are growing, and which are losing engineers.
From your intakeSignal · departures
Radiant's profile count is up 30% in six months. Peers are moving at very different speeds. Since April, 30 engineers left TerraPower, for Zap Energy, Blue Origin, Helion, Framatome, ZettaJoule, Hadron Energy and Ocean Atomics. Kairos Power and X-energy lost 7 each, Kairos to Astranis, Antares and Inertia among others. A team losing people is a team to recruit from.
How it runs
- Track headcount by function at each peer with
company_enrich.
- List engineering departures every month, and where each person went, with
person_search on past company and end date.
- Flag the spikes, then pull the teammates who stayed. The same run covers aerospace peers like SpaceX and Anduril.
A monthly brief on the peers you compete with for talent, instead of hearing about a reorg from a candidate.

Advanced nuclear peers · engineering profilesOct 15, 2026
Engineering profiles in our index, not company headcount, as of early September. Departures: engineer titles that ended since April, checked live and in our index through Oct 15, interns and moves to sister companies removed.
04
Size the pool before you open the req.
From your intake
Every function Radiant hires for has its own market. In the US, 348 people have turbomachinery in their current title, and 93 of them are in California. Embedded and firmware has more than 29,000. That gap decides whether a req is a sourcing problem or a closing problem, and how wide the search has to go on day one.
How it runs
- Turn each open req into title, skill and past-employer filters with
person_search.
- Count by region and seniority, then by the companies the pool sits at.
- Re-run monthly so the kickoff numbers stay current as the market moves.
Every req kickoff starts with a real number: how many people fit, where they are, and who employs them.

People by current title · US and CaliforniaOct 15, 2026
A first cut on current titles, with interns, students and technicians removed. Roles from Radiant's recent postings. The skill tightens each count with skills, seniority and past employers.
05
Find the people who've already built a microreactor.
Only Radiant can run this one
Microreactor experience is the rarest line on a nuclear resume. 248 engineers and leaders in the US, outside Radiant, list microreactor work at a nuclear company or national lab, on programs like Westinghouse's eVinci, Idaho National Laboratory's MARVEL and BWXT's Project Pele. 146 of them have already left the employer where they did that work, so they do move. Only 8 live in California, so this one runs as a national search.
How it runs
- Search role descriptions for microreactor programs with
person_search, interns and students removed.
- Enrich and score each person against the req (core physics, thermal-hydraulics, I&C, power conversion) with
person_enrich.
- Watch the list for moves and tenure marks with
watch_create, and add new matches as profiles change.
The shortest list in nuclear, kept current. No job board hands you this one.
