Senior Full-Stack Developer

[…] shows businesses how they appear in AI-generated answers. We track citations, sentiment, and visibility across every major AI engine, and we process billions of crawler logs and AI responses in real time. Thousands of companies use the product to make decisions every day.

In this role you own features from start to finish. You scope them with product and design, build the schema and the API, ship the UI, and keep an eye on them in production. You work directly with the founders, with no management layers between you and the decisions.

The stack is a TypeScript monorepo (React, Next.js, Fastify, Prisma, tRPC) on Postgres, Elasticsearch, Redis, and ClickHouse, running on Google Cloud. It's split into several services, including the API server, an AI gateway, ingest pipelines, and log processing, and each one has its own scaling problems.

• Take features from problem definition to production: scope with product and design, build the schema, write the API, ship the UI, and monitor it once it's live
• Design and improve the data pipelines that move millions of records a day through Postgres, Elasticsearch, Redis, and ClickHouse
• Build and run services on Google Cloud (Cloud Run, Pub/Sub, CI/CD) and keep them observable with Sentry, structured logging, and custom dashboards
• Help shape how we work: code review standards, testing (Vitest, Playwright), and technical direction
• Work directly with the founding team on what to build and how
