About Trigger.dev

Trigger.dev is the platform for running reliable AI agents and workflows. Developers use it to build, deploy, and scale production systems with built-in tools for orchestration, scheduling, monitoring, and debugging.

Our Cloud product is a managed service where we deploy our users code and auto-scale from zero to millions of executions. Today, we serve thousands of teams building AI apps and agents, handling hundreds of millions of executions per month.

About the position

Were looking for a Senior Backend Engineer to help us build our Open Source and Cloud product. The ideal candidate will have deep expertise in Node.js, TypeScript, Postgres, Redis, and cloud infrastructure. This role requires both technical depth and the ability to think strategically about our platforms future.

What youll be doing

Youll do a variety of things including:

• Designing and implementing SDK and platform features. Shipping new capabilities end to end, from API surface to production rollout.

• Database design. Developing database schemas and data models that hold up as the product scales.

• Query performance and data access. Creating and optimising query performance and data access patterns.

• Building backend systems that stand up to production load. Reliability, throughput, and durability are part of the job, not someone elses.

• Scalable APIs and services. Designing and implementing API endpoints and services that handle real customer traffic.

• Security as a default. Applying security best practices in everything you ship.

• Monitoring, logging, and debugging. Implementing the observability tooling that lets us spot problems and fix them fast.

• Architecture and technical roadmap. Contributing to architectural decisions and shaping where the platform goes next.

We build in public, so you can see some of the things you might work on here.

Working at a Commercial Open Source Software company is more than just coding:

• We have an active community on Discord and GitHub. Everyone on the team helps customers, reviews PRs, and creates issues.

• Having great documentation is essential. Everyone writes docs.

• Were a product-led growth company, so everyone is expected to get involved in creating content like code examples, blog articles, videos, and tweets.

Requirements

You really need to have:

• Expertise in Node.js and TypeScript. We use Remix.

• Expertise with Postgres and Redis. Youve designed schemas, tuned queries, and run these in production.

• Cloud infrastructure experience. AWS, GCP, or Azure.

• Comfortable being on call. Reliability is a shared responsibility for the engineering team.

• Open to in-person events throughout the year. If youre remote, well arrange these so the team gets real time together.

Youll be an amazing fit if you have:

• A proven track record of contributing to open source projects.

• Previously been a venture-backed startup founder.

• Experience with React, or better still, Remix.

• Worked on a high throughput system.

• Designed SDKs for developers.

• Experience with self-managed Kubernetes.

• Familiarity with Linux.

• OTel or o11y experience.

• Worked at a developer tools company.

• Experience with Go.

• We care about our customers and the open-source community.

• Being a start-up, the work is challenging and fast-paced, but we also understand the importance of taking time off to recharge.
