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.
