How it works
Set it up once. Zefra hunts every day so you don't have to.
Upload your resume & papers
Drop in your CV and a few representative papers — Zefra reads them and builds your matching profile from what you've actually done. Review it, edit it, done.
Zefra scans overnight
Every posting on 4,600+ boards is embedded and ranked against your profile; the finalists are scored by an LLM for genuine fit.
Review your matches
A scored dashboard with reasoning and concerns for each role. Mark what's not a fit — Zefra learns and stops showing you more of it.
Built for PhD careers
Generic job boards bury PhD-level researchers in irrelevant listings. Zefra matches on what you actually do — and knows a postdoc from a staff-scientist role.
◎Semantic matching
Embedding search over every posting — it understands "MLIP" and "electrocatalysis", not just keyword overlap.
✓Fit scores with reasoning
Each match is scored 0–100 with the skills that matched and the concerns worth knowing before you apply.
↺Learns from your feedback
Rejected roles become exclusion rules automatically — the feed gets sharper the more you use it.
⌁Dead links, handled
Closed postings are detected daily and cleared out, so you never draft a cover letter for a filled role.
◈Beyond the big boards
National labs, academic boards, and company career portals — sources the aggregators miss.
☾Runs while you sleep
Fully automated daily runs in the cloud. Open your dashboard with coffee; the scouting is done.
Stop searching. Start choosing.
