ABOUT US
Caddie Intelligence builds software for analytical testing laboratories and other regulated industries.
WHAT WE'RE BUILDING
Something meaningful, in an industry that quietly touches billions of lives and almost nobody thinks about.
The work inside it is slow, manual and consequential and the decisions being made every day deserve to be faster, more consistent, and easier to stand behind.
THE ROLE — you will build it end to end:
The review surface — TypeScript, React, SVG and Canvas over tens of thousands of data pointsInteraction — pointer events, drag, requestAnimationFrame, state that never disagrees with what is drawnBinary data in the browser — ArrayBuffer, DataView, typed arrays, Web WorkersClient-side exports — ZIP, XLSX and PNG generated in the browser, byte-exactThe platform screens — configuration, review queues, audit trail, adminThe plumbing — Vite, component and end-to-end tests in Playwright, CI that blocks regressions
WHAT YOU'LL NEED
Strong TypeScript and React, and an eye for how something should look and feelYou have built a data-heavy interface that stays fast — not a CRUD app with a chart library dropped inRendering performance as a skill: SVG, Canvas, and knowing when the browser is lying to youEnough backend ability to ship an endpoint yourself — Python, Postgres, an AWS service or two.
Nobody is handing you a finished APIYou use AI tooling hard, and you are ruthless about reviewing what it writes (Cursor, ClaudeCode, Codex, etc..)
WHO YOU ARE — critical thinker who pushes back · proactive, nobody is going to hand you a ticket · wants ownership of the schema, the screen and the alarm that wakes you up · fast without being sloppy · ability to handle adversity
