Software Engineer, Compute

About the role

About Vercel:

Vercel is the agentic infrastructure company, freeing people and agents to ship what's next. For more than a decade we've helped builders move from idea to production with speed, security, and exceptional developer experience.

Now we're scaling our products for both agents and people to ship and run software, built in the open and trusted by OpenAI, PayPal, Ramp, Supreme, and millions of developers worldwide.

About the role

Developers are building faster than ever. Humans and agents are deploying more than 6 million times a day on Vercel, spinning up over 2 million Sandboxes and serving a trillion requests per month. Every single one is powered by our own compute infrastructure.

The Persistence team sits within Vercel's Compute division. This team owns the deep infrastructure within Hive (our compute platform) focussing on storage and state for all our workloads (Builds, Sandboxes and Functions). This work is redefining compute with features like Fluid Compute, Persistent Sandboxes, and Custom Images.

As a Software Engineer on the Persistence team, you'll work on the infrastructure that runs 100s of instances across every region where our customers deploy code, rethinking low-level primitives and contributing to platform features that improve the experience for thousands of developers every day.

This role is based in London, UK. If you're within commuting distance of our London office, the role includes in-office anchor days. If you're located further afield within the UK, the role is fully remote. For location-specific details, please connect with our recruiting team.

What you'll do

- Manage and improve our fleet of clusters, running 100s of instances deployed in every region where our customers deploy and run their code.

- Write Golang on a daily basis and use Terraform to provision infrastructure; you'll get to know Nomad as our scheduler for managing workloads.

- Rethink the primitives of our infrastructure — working with virtual filesystems, Linux primitives, and low-level virtualisation.

- Own the reliability and performance of our compute platform, including on-call coverage for a team where every improvement has outsized impact at scale.

- Collaborate across teams to drive the convergence of all compute at Vercel.

What you need

- 5+ years of software engineering experience, with Golang strongly preferred.

- Deep experience with virtual machines, file systems and Linux — you like knowing how things work under the hood (tcpdump, strace, and iptables are familiar tools).

- Experience building and operating distributed systems at scale; you design for performance and reliability.

- Experience with schedulers and orchestrators for managing containers and non-containerised workloads (e.g. Nomad, Kubernetes).

- Excellent problem-solving and communication skills, with a genuine enthusiasm for digging into problems that don't have obvious solutions.
