Job Description

About the role

We're looking for an experienced DevOps Engineer to join our Cloud Infra team at Synthesia. Cloud Infra is a group that enables our Product engineers to build, and deploy Synthesia state of the art technologies.

You can expect to work across cloud infrastructure, CI/CD pipelines, observability, and tooling, with autonomy to identify and fix bottlenecks in a fast moving AI company.

This is a hands on senior IC role (roughly level 5 scope). You'll be joining a growing team that's shifting from enablement to direct execution, and you'll help shape how we scale our infrastructure over the next year.

What you'll do
  • Maintain and scale Kubernetes (EKS) clusters - managing workloads, deployments, and monitoring at production scale.

  • Manage and evolve our AWS (and some GCP) cloud environments, balancing reliability, cost, and velocity.

  • Own and improve our CI/CD systems (GitHub Actions on our self hosted AWS runners).

  • Define and implement Infrastructure as Code using Terraform and Terragrunt.

  • Strengthen observability via Datadog and enable teams to understand their systems in production.

  • Collaborate with Product Engineers to deploy and monitor production services.

  • Drive FinOps practices: vendor management, cost allocation, and financial feedback loops.

  • Contribute to internal tooling, automation, and reporting platforms that improve developer experience.

You'll thrive in this role if you have:
  • Deep hands on DevOps / SRE / Platform experience in a SaaS or high traffic product environment.

  • Strong Kubernetes experience - spinning up and managing clusters, not just consuming them.

  • Proven AWS and/or GCP expertise.

  • Proficiency with Terraform / Terragrunt, Linux, and Python scripting.

  • Strong understanding of CI/CD design patterns.

  • Experience with Datadog or similar observability tooling.

  • Comfortable operating autonomously in ambiguous environments.

  • A pragmatic mindset - focusing on scalable, maintainable solutions over theoretical perfection.

  • A bias toward execution and written communication, especially in remote contexts.

Bonus points
  • Familiarity with Temporal.io, or workflow orchestration frameworks.

  • Light frontend or tooling development experience (React, Node.js).

  • Previous work supporting AI research or data intensive environments.

Other important info
  • This is a remote role from an EU country, UK or Switzerland or hybrid from one of our London, Munich, Copenhagen, or Zurich hubs.

  • This is full time employment only - no contractors possible - usually through OysterHR or a local entity.

  • We only sponsor visas if you are in the UK or some EU countries already.
