Descrizione del lavoro

Pandektes is building the largest AI-powered legal database in the world. Behind it is a backend that has to ingest, structure and search a huge database of legal information.

We’re looking for a Senior Backend Engineer to help us making sure that the legislation and volume of data stays stable so we can scale our services so we can ingest larger volumes of data, more efficiently.

We have recently closed our Series A round and joining now means you will have a big impact how we grow in the future. This role is based in our Copenhagen HQ.

About Pandektes

Our mission is to rebuild legal research from the ground up. Lawyers still lose countless hours to fragmented sources, outdated systems, and databases that fight them at every turn. We're building the largest AI-powered legal database in the world to make that friction disappear.

We're a team of 45+ based in our Copenhagen HQ, Zurich, London, and Hamburg. We’re a small team with high trust and flat structure. We move fast, argue our positions, and ship. If your input is good, it gets implemented - often within hours, not sprints.

Pandektes has raised more than €17.5 million and most recently closed a €13.5 million Series A round (October 2026) led by Alstin Capital, PROfounders and Scale Capital. Pandektes already serves more than 450 customers across Denmark, Germany and Switzerland.

The experience you’ll bring

• You’ve built and operated backend systems that real customers depend on. You can work through questions about data, APIs, performance, and security, and explain the consequences of your decisions.
• Experience integrating AI technologies like OpenAI and Pinecone into production systems to build innovative, data-driven solutions. Experience with vector databases, transformers, NLP and LLMs is a plus.
• Our stack includes TypeScript, NestJS, GraphQL, Postgres, and Prisma. We also work with OpenAI and Turbopuffer. Experience with these tools is useful; we’re especially interested in what you’ve built with them and the decisions you made along the way.

What we value

“How fast can we ship this?” comes up a lot at Pandektes. So does “we should take our time with this one.”

Knowing which question to ask is a big part of being an engineer here.

Knowing when it’s good enough

We like getting things into customers’ hands quickly. That means making trade-offs, questioning scope, and accepting when something is good enough for now. There’s usually another approach to explore or another prompt to try. At some point, you have to ship.

We use AI throughout our development process. AI code reviews, feature flags, and remote coding agents running end-to-end tests help us move quickly with confidence. Deciding what to build, what to check, and when it’s ready still takes judgment.

We value people who can find a smaller version worth shipping, explain the trade-offs, and follow through once customers start using it.

Knowing when to slow down

Some decisions deserve more time. Getting them right makes everything that follows easier. Getting them wrong means paying for the same mistake repeatedly.

Our default is to move quickly, so slowing down takes discipline. Sometimes it means pushing back when the rest of us want to get something out. We value someone who can explain why the extra work matters, challenge an approach, and help us decide where to spend our time.

You’ll have room to make those calls here, and teammates who will question them. We expect you to do the same for us.

Make time to experiment

We enjoy trying things before we know whether they’ll work. A new tool, a different way to use an agent, an idea that might turn out to be useless. Finding out is part of the work.

Once a month, we get together to demo our setups, show what we’re experimenting with, and share what we’ve learned. Sometimes we invite people from outside the team to show us how they work. Those sessions have changed how we build software.

We value curiosity and the generosity to bring other people along. If you find something useful, show us. If an experiment fails, we’d like to hear about that too.

We try to watch this video once a month to keep this value top of mind.

What we offer

You’ll join at a point where there’s still a lot to shape. We offer competitive pay and equity so you can share in the success you help create.

• Your own Pleo card for the tools and work expenses you need
• 25 vacation days a year
• public holidays
• paid parental leave when your family grows

We also make time to get together away from our usual work. Our last team trip was to Barcelona, and we’d love to have you along for the next one.

We believe diverse teams build better products and stronger teams. We embrace and encourage people from all backgrounds to apply regardless of race/ethnicity, colour, religion, nationality, gender, sex, sexual orientation, age, marital status, disability, socio-economic status, culture or beliefs.
