Senior Platform & DevOps Engineer

Auctionet is a marketplace where auction houses from Sweden, Great Britain, Finland, Spain, Germany, and Denmark sell furniture,

art, design objects, collectibles, and much more. We are now looking for a Platform & DevOps Engineer who wants to build the

infrastructure our engineers — and increasingly our AI agents — run on.

The foundation is familiar work: the infrastructure behind a marketplace used by over a million buyers, the pipelines our product

teams ship through, and the developer experience that decides whether shipping feels easy or heavy.

The new part is AI infrastructure. We're building internal tooling and automation with AI agents, and we need to decide how those

agents are hosted, sandboxed, authenticated, and given controlled access to our data and our product. That means building real

applications and APIs, not only configuring things. It's close to greenfield — you'd be part of shaping it rather than inheriting

it.

You'd be the third engineer in Platform & Infrastructure, alongside our Lead — who owns technical direction for the platform — and

a senior engineer. Three people supporting a tech department of around 30, plus systems used well beyond Tech. That means you get

real ownership early, and it means judgment about what to automate matters more than raw throughput.

• Building internal APIs and platform applications so agents, automations, and internal tools have a stable, documented,

permissioned way into Auctionet's data and product.

This role is based in Stockholm, hybrid (partly remote possible). Working language is English, and we'd like to start as soon as

possible. On-call is voluntary and compensated.

We run our own Kubernetes on Hetzner, with additional infrastructure on AWS and an assortment of smaller services around the main

stack. The platform carries around 1 million end customers, 80 auction house customers, and roughly 1,000 admins working in the

auction house system every day — so this is real production traffic with real business hours behind it.

Our product teams build in Ruby on Rails, with Turbo, Stimulus, and PostgreSQL. We also have systems built with Elixir and

Phoenix. We care about how we build: maintainable code, solid test coverage, continuous deployment, and the kind of

well-established best practices that keep a codebase healthy over years rather than months.

Auctionet runs the leading online marketplace for European auction houses — art, design, furniture, and antiques. We have around

170 employees and are the parent company of a wider group with roughly 400 colleagues across multiple countries. Our main office

is near Stureplan in central Stockholm, with logistics centres in Malmö, Stockholm, Gothenburg, Westbury, and Köln.

• Solid infrastructure and operations experience, with infrastructure-as-code as your default rather than a project you keep

meaning to start.

• Kubernetes experience with a genuine understanding of what's underneath it — we run our own clusters, so this isn't abstracted

away.

• Real software engineering ability — you build and maintain applications and APIs, not only configuration. This role writes

code.

You don't need to have done the AI part before. Nobody has been doing it for long. If you've built platforms for other engineers

and you're curious about this, that's a strong start.

We see hiring as a two-way thing. We're mindful of your time, but we also want to spend enough of it together for both of us to

get a real feel for working as a team — a short intro call, then two or three conversations with the team, and a small take-home

exercise you can do in your own time. No whiteboard puzzles — we'd rather talk through real work together.

If you're excited about this role but don't tick every box, we'd still love to hear from you. Very few people match every point —

so if you're close and motivated, please apply.

In 2021 Auctionet acquired the auction house Stockholms Auktionsverk, and we are now by far the largest auction marketplace in the

Nordics, and one of the larger auction marketplaces in the world. With this acquisition, Auctionet owns and operates both the

oldest auction house in the world (1674) and the second oldest (1681), which means we have been working with sustainability for

350(!) years.
