The Challenge
The Solution
Key Metrics
Core Features
1. Live open-role counter
The homepage opens with the number of open roles right now, next to a bar graph of the past five days. The heat reading shows at a glance whether hiring is picking up or slowing down, so a candidate knows the state of the market before they scroll.
2. Job sourcing via public APIs
The About page shows the pipeline in motion. Listings flow in from three public job APIs, pass through the rules engine, and land on the board. Every listing comes from a company’s own job system, and nobody enters data by hand.
3. Search and filter by seniority and industry
Candidates search by title and narrow results by seniority and industry. Because each role already has one of eight precise levels, a filter like “Senior” returns senior roles only, not the usual catch-all bucket.
Calls I Made
Rules first, UI second
Trust depends on getting the rules right, so I designed them before the interface. I wrote the spec as a 110-line rules file that the AI agents read on every request. Grok set up the front end and Neon database, Cursor Agent handled the first build, and Claude Code handled iteration.

Edge cases are where trust is won or lost
- “Lead” maps to Staff, or to Manager if the role has direct reports.
- “Head of Design” counts as Executive at a startup and Director at a larger company.
- A Senior title that asks for 3 years of experience gets a Stretch badge, so candidates don’t rule themselves out.
- Chip design, mechanical design, and design recruiter roles are filtered out.
Eighteen test files check each rule against real job titles.
A quiet interface
The interface stays plain so the listings stand out: Fjalla One headlines, Work Sans body text, thin borders, and pill controls. I chose the accent color by contrast. Green failed at 3:1, and blue (#0073e6) passes WCAG AA at 4.57:1.
A design system that enforces itself
Since agents wrote most of the code, a test fails any component that uses a raw hex value, a gradient, or a heavy shadow instead of a token.
Keeping every company fresh
Vercel’s 60-second function limit cut the nightly run off at company 89. I split the job into three staggered runs that each handle every third company, and the next night all 107 refreshed with no timeouts.
Results
Next: Saved roles with a free sign-up, and a weekly newsletter with 3–5 roles matched to each reader’s level.
