Platform Engineer (AI-First)

Bloom; Aarhus; On-site; DKK 700,000 - 900,000; Full time

Job summary

Aleta, an AI-first wealth intelligence platform, seeks a Platform Engineer to keep a high-availability system in Aarhus. You’ll manage the end-to-end ingestion pipeline and ensure correct calculations from nightly batch runs.

You’ll work with the founders and tech lead to shape architecture, debugging production issues at odd hours. Strong TS skills are essential; Rust is a plus, and AI-centric thinking is valued.

Qualifications

• Own something in production, on call or on-call responsibility.
• Solid ground beneath the application layer: Linux, networking, deployment, databases.
• SQL and data modelling at a level where you can tell a query is 'wrong'.
• Strong in TypeScript; Rust welcome but not required.
• AI is already your primary engineering method, with opinions on where it fails.
• Based in or near Aarhus, this role sits with domain knowledge.

Responsibilities

• Keep it running: identify what happened at 03:14 from logs, metrics and traces.
• Own the ingestion chain: bank files, custodian feeds, changing formats.
• Review what the agents ship: read code quickly and spot subtly wrong outputs.
• Notice when figures look off: ensure data accuracy, not just crashes.

Job description

Would you enjoy keeping the WealthTech platform behind DKK 100 billion in assets running? – then this might be the role for you!

On behalf of our client Aleta, we are looking for a technically ambitious and AI-First Platform Engineer to keep the platform running.

The company Aleta is a wealth intelligence platform headquartered in central Aarhus for family offices and their advisors. They consolidate data across banks, custodians, asset classes and entity structures, and turn it into reporting that owners use. They have an established business, strong revenue growth and offices in Aarhus, New York and Bangkok.

Most of their code is now written by AI agents. That hasn’t removed the engineering work — it has moved it. Knowing whether the service is correct, and keeping it alive at three in the morning, is not. That second part is this job.

About the platform

Rebuilt from scratch with TypeScript and Next.js on the application layer, Rust for the calculation engine, Postgres on Neon, WorkOS for auth, fully serverless. No legacy systems to work around.

Every night it ingests data from banks and custodians, runs the calculations, and produces reports that have to be right by morning. When that chain breaks, someone has to find out why — quickly.

What you’ll do

• Keep it running: You’re the person who can answer “what happened at 03:14?” from logs, metrics and traces — and who makes the answer easier to find next time.
• Own the ingestion chain: Bank files, custodian feeds, the formats that change without warning. Most of what goes wrong, goes wrong here first.
• Review what the agents ship: You read code faster than you write it, and you’re constructively suspicious of output that looks plausible. Catching the subtly wrong matters more here than writing the elegantly right.
• Notice when a number looks off: Aletas systems rarely fail with a stack trace. They deliver a quiet, incorrect figure. Wanting to know whether the data is actually right is a core skill, not a nice-to-have.

You’ll work alongside the founders and the technical lead. On architecture you help shape it, but don’t have to own alone.

Who are you?

We care more about what you’ve learned and what you’ve owned than the number of years on your CV.

The important checks are:

• You’ve ‘owned’ something in production, not just built it. You’ve been on call, or you’ve been the person people called.
• Solid ground beneath the application layer: Linux, networking, deployment, databases. You debug downwards, not only sideways.
• SQL and data modelling at a level where you can tell a query is ‘wrong’, not just slow
• Strong in TypeScript. Rust is welcome, not required
• AI is already your primary engineering method, and you have opinions about where it fails
• Based in or near Aarhus. This role sits with the people who hold the domain knowledge

More about how they work at Aleta

‘AI-first isn’t a slogan here’

It’s how the whole company runs. Every task is a written goal with an explicit definition of done, and the rules are files in the repo, not aspirations.

‘Deliberately small’

‘Direct and honest’

At Aleta, they argue about the work, openly and without politics — including with the founders.

What Aleta offers

You’ll have direct access to the people making product and technical decisions, and you’ll see the impact of your work immediately. With a small team comes real ownership, short feedback loops, and the opportunity to influence both the platform and how engineering is done.

We’re more interested in understanding how you think than reading a polished CV. Tell us about something you’ve actually solved. We want to know what you actually did.
