Frontier
An engineering job board and a morning AI briefing that delete themselves — nothing on Frontier is older than seven days.
About
Frontier reads company career pages, open job feeds and freelance marketplaces every thirty minutes, files what it finds into nineteen engineering disciplines, and throws away anything older than seven days. Postings come from the source — Greenhouse, Ashby, Lever — never a middleman, and every listing links out to the company's own page.
What it does
A relevance gate reads the job title alone and discards about three quarters of what arrives, because a narrower board that is right beats a bigger one that is not. Nothing is kept that cannot be shown, so a closed role returns a real 404 instead of wasting the click. Beside the board runs a morning briefing on AI and startups drawn from around forty sources, with near-identical headlines collapsed into a single story. Next.js and TypeScript on Vercel, Supabase for storage and auth, Upstash Redis for rate limiting, and a Cloudflare Worker cron driving the thirty-minute refresh.
Everything open. Nothing stale.
