Job description

Zof AI is seeking a Full Stack Software Engineer to build and ship whole features across our control plane for software quality. This role spans the Next.js, React, and TypeScript surfaces where customers review agent findings and the Node and Postgres services that store runs, evidence, and validated fixes. If you have worked as a Software Engineer, Product Engineer, Web Developer, or Application Developer, this is that discipline at Zof AI. The ideal candidate has shipped real features to real users, moves fast without leaving quality behind, and already builds alongside AI coding agents every day.

Engineering · Mid-level · Full-time · On-site · San Francisco, CA

Responsibilities

• Build and ship whole features end to end, from interface to database.
• Develop the React and Next.js surfaces where customers review agent runs, evidence, and proposed fixes.
• Design Node services and Postgres data models that keep run history and evidence trustworthy.
• Own features through design, review, release, and the follow-up after they land.
• Write tests and instrumentation so regressions surface in our own product before customers hit them.
• Partner with design and product to turn rough direction into working software.
• Use AI coding agents daily to raise throughput without lowering quality.
• Improve performance, accessibility, and reliability across the stack.

Requirements

• Experience building and shipping web applications in production.
• Working fluency with JavaScript or TypeScript, React, and Node.
• Comfort writing SQL and reasoning about relational data models.
• Ability to work across the stack rather than a single layer.
• Willingness to use AI coding tools as a daily part of the job.
• Strong ownership and follow-through on the work you pick up.
• Clear written and verbal communication.
• Comfort operating in a fast-moving environment.

Nice to have

• Experience with Next.js, Prisma, Postgres, or similar technologies.
• Experience using Cursor, Claude Code, Codex, or similar AI coding tools.
• Experience with test automation, CI pipelines, or developer tooling.
• Portfolio, GitHub projects, or open-source contributions.

Daily, hands-on use of AI coding tools in your normal development workflow is required
