Job description

Factbird helps manufacturers turn real-time production data into decisions they can actually act on. Since 2016, we've helped manufacturers in 28 countries cut waste, boost uptime, and run smarter — from the shop floor to the boardroom. Over 300 companies trust us to make sense of their operations, and we're a team of 80+ people across Copenhagen and the US who care about making complex things simple.

Department: Cloud

Location: Copenhagen

About the role

We're open on where your strengths sit. Some of these roles will lean more toward the back end — APIs, data pipelines, cloud infrastructure. Others will lean more toward the front end — the interfaces our customers use every day. What matters is that you're genuinely full stack: comfortable owning a feature end to end, and willing to work across the stack when the team needs it. We're not looking for anyone who only does front end or only does back end.

We’re looking for confident independent contributors that lean into ownership, are keen to shape architecture, and invest in mentoring others.

You’ll fit right in if you've got a pragmatic, get-it-done mindset, a good instinct for testing and clean design, and you’re just as happy explaining a technical trade-off to another engineer as to someone outside engineering.

What you’ll do

• Operate within a Nix-backed ecosystem from development tooling to cross-compiled build artifacts
• Own features end to end — from a rough idea or user story through to a shipped, tested, monitored piece of production software
• Build and maintain frontend features in React and backend services in TypeScript on Node.js and Rust, backed by a multi-account orchestrated AWS environment (Lambda, API Gateway, RDS, DynamoDB, EKS, and more, depending on the team)
• Write infrastructure as code (e.g. AWS CDK) for the systems you build

Team & growth

• Take part in code reviews—giving and receiving feedback that makes the codebase better
• Contribute to sprint planning, story breakdown, and demos
• Design systems and data pipelines from scratch, mentor other engineers, author RFCs and architecture decisions, and help set technical standards for the team

About you

We’re looking for engineers who’ve seen more than one way of doing things, and who’ll bring that perspective to challenge how we do things here — with a pragmatic, get-it-done mindset that can turn ambiguity into a plan.

The ideal background

• At least five years experience since graduating from a relevant Masters program
• Solid, hands-on experience across the full stack — frontend (React or equivalent) and backend (Rust/Node.js, or equivalent) — even if you have a natural preference for one side
• Comfort working with AWS or another major cloud provider
• A track record of shipping features independently, with a good instinct for testing, code quality, and clean design
• Good communication — you can explain a technical trade-off clearly, whether you’re talking to another engineer or someone outside engineering. And you can do all this with strong English fluency.
• Experience designing systems from scratch, mentoring other engineers, or driving architecture decisions through to a decision

We welcome applicants from people eager to move to Denmark so long as you already have the legal right to live and work here. We can contribute to relocation costs for the right candidate.
