Sr. Full-Stack Engineer

The Role Cruva is the operating system for TikTok Shop. Over 1,400 brands use us to find creators, manage affiliate programs, and run their commerce operations on the fastest-growing platform in the world. We ship fast, move massive volumes of data, and own our stack end to end. You will work across the full stack on the product that brands and creators depend on every day. That might mean designing a new ClickHouse schema to unlock a query pattern we could not run before, building a Next.js dashboard, or writing a Lambda that reliably scrapes a tricky TikTok Shop endpoint. You will architect, ship, debug in production, and have real say in what gets built next. We do not hand you a ticket backlog. We hand you problems and trust you to solve them. What You'll Do Design and build across the full stack: Next.js on the frontend, AWS (ECS, ECR, Lambda) on the backend, Postgres, ClickHouse, and MongoDB for data. Build and maintain web scraping pipelines and automations across TikTok Shop at scale. Architect new features end to end, from schema design through deployment. Debug in production and take ownership of system reliability. Contribute to technical roadmap decisions. We do not hand you tickets; we hand you problems. What You'll Bring Production systems that real users depend on, at real scale. Not toy apps or abandoned side projects. Deep full-stack range. You can take a feature from idea to deployed without handoffs. Strong AWS experience, especially containers (ECS/ECR) and Lambda. Experience with high-volume data systems. ClickHouse is a strong plus. Comfort building web scrapers and automations that do not break when a target page changes. A bias toward shipping. You would rather have something live and iterating than perfect in a doc. Compensation To be discussed depending on experience, plus meaningful early-stage equity. Location Remote (LA Preferred)
