About the role
Every business runs on its books, and more of that work is moving to AI agents every day. Sumary is building the platform that work will run on. Leading accounting firms already trust us with their clients' books. The largest bring thousands of client books and millions of transactions each, with agents doing real work on them around the clock.
As an Infrastructure Engineer, you will join our infrastructure team and help build the backbone of Sumary: the databases, workflow engine, compute and observability everything else depends on. The challenges are big. You will make the platform scale across Europe, keep it fast, reliable and secure, and earn the trust of firms that handle some of the most sensitive data there is. You will be based in our Copenhagen office.
What you'll do
- Scale our production platform across Europe, from Postgres and Supabase to Temporal workers and Modal compute
- Build infrastructure as code, deployment pipelines and environments that are easy to reason about
- Own observability, from metrics, logs, traces and alerting to the on-call practices around them
- Scale the long-running workflows and sandboxes the AI CFO and our agents run on
- Work with our Compliance & Security Engineer on access control, encryption, backups and disaster recovery
- Keep cost and complexity in check as we grow
What we're looking for
- 3 to 5 years of experience running production infrastructure
- Hands-on experience with cloud infrastructure, containers and infrastructure as code
- Strong Postgres knowledge, from performance tuning to safe migrations
- Experience setting up observability and incident response
- A habit of automating anything you do twice
Nice to have
- Experience with Temporal, Supabase or Modal
- Experience running infrastructure under SOC 2, ISO 27001 or similar audits
- TypeScript
