About KiwiRank

KiwiRank does SEO for small and medium businesses. It reads a business’s website, researches its competitors and the questions its buyers ask, then writes illustrated articles made to be found on Google and in AI answers.

Customers connect their site once and KiwiRank publishes to it, on WordPress, Shopify and more. They get articles on their site without hiring a writer or an agency.

What you’ll do

• Ship features across our React app, Cloudflare Workers and Supabase Postgres.
• Own the long-running research and writing jobs on Cloudflare Workflows: retries, cost ceilings, and failures handled before a customer sees them.
• Build and harden the integrations that publish articles to customers’ own sites, starting with WordPress and Shopify.
• Work on the AI pipeline: Claude for research and writing, image models for illustrations, and the checks that keep every link pointing at a page we fetched.
• Write the migrations, tests and rollback plans that let each small, reviewed release ship on its own.

What we look for

• You have five or more years building production web apps and have owned both the front end and the back end.
• You write strong TypeScript and React and are at home in SQL: Postgres functions, row-level security, migrations.
• You have run serverless or edge code in production. Cloudflare Workers is a plus.
• You have built on LLM APIs and know where they fail.
• You care about what the customer sees: copy, empty states, error messages.
• You write clear English and explain a trade-off in plain words.
