Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100.

Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US.

As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations.

Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion.

Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow.

Remote (US East Coast preferred, for timezone coverage) About the team Cloud Infrastructure owns the platform every Synthesia product runs on β€” AWS, Kubernetes, Mongo DB, Temporal, our observability stack, and the vendor and cost relationships underneath them.

We're a small, high-leverage team scaling toward a domain-ownership model: small groups that both build and operate the systems they're accountable for.

The role We're hiring a dedicated SRE to take real ownership of operational excellence across Cloud Infrastructure.

Today, too much critical operational knowledge β€” vendor relationships, cost management, and incident response β€” lives with one or two people.

Your mission is to take genuine ownership of those domains, make them resilient to any single person, and raise the bar on how reliably we run.

This is not simply a ticket-queue or keep-the-lights-on role.

You'll own domains end to end: understand them deeply, operate them well, and build the automation and tooling that make them boring.

We deliberately pair operational and engineering work so the role grows rather than narrows.

What you'll own Incident management comfortable with Mongo DB and scripting/automation in Python .

An operations-and-reliability mindset β€” you take pride in systems that run quietly β€” paired with the instinct to engineer the problem away rather than absorb it manually.

Sound judgement on incidents and risk; calm and clear under pressure.

Influences through relationships and evidence, not escalation; comfortable owning a domain and partnering across teams.

Bonus: vendor/cost management exposure, Temporal, observability tooling.

How we think about this role We don't letterbox engineers.

You'll have a clear primary mission (operational excellence) but real domain ownership and the mandate to build β€” not a fixed lane.

We expect the shape of the role to evolve as the team grows. #J-18808-Ljbffr
