Passionate about building secure, innovative solutions powered by data and data?

About the team:
We are a small, high-impact team with big responsibility, we own the full stack for DNB's communication services across web and mobile channels. Working in a BizDevOps model, we sit at the intersection of business, development and operations, making sure our decisions are driven by both customer needs and technical excellence. With lean structure comes real ownership: every team member has a meaningful voice in how we build, ship and run our services. You'll be joining a tight-knit group where collaboration is close, the work is varied, and your contributions are visible.

What will your day look like? You'll take end-to-end ownership of what you build, from scoping and specifying requirements together with stakeholders, through design and development, all the way to deployment and production operations. No handoffs, no silos. You'll work across the full backend lifecycle: designing APIs, building services, reviewing incidents and iterating quickly on feedback. Because we're a small team, you'll often be the one driving a feature from the first conversation to the last deploy. You'll collaborate directly with frontend engineers, product owners and business stakeholders to make sure what we ship is both technically sound and genuinely useful.

What kind of developer are we looking for? We're looking for someone who wants real ownership, not just a ticket to close, but a problem to solve. You're comfortable stepping into ambiguity, asking the right questions, and turning business needs into concrete technical solutions. You take responsibility for the full lifecycle of your work and don't wait for someone else to define the next step. At the same time, you're a team player who communicates openly, shares knowledge, and helps the team grow. You thrive in a small team environment where autonomy and accountability go hand in hand.

Your knowledge and skills:

Strong expertise in Kotlin and Java, with solid knowledge of multithreading, Kotlin Coroutines, and functional Programming

Hands-on experience building and deploying production services on AWS using Infrastructure as Code (Terraform or CDK), with deep understanding of API Gateway, Lambda, SQS, ECS, EC2, VPCs and networking

Proven ability to design, build and operate high-performance, low-latency distributed systems, troubleshooting at scale comes naturally to you

Strong data modelling skills across both SQL (PostgreSQL) and NoSQL (DynamoDB)

Experience with CI/CD pipelines and a DevOps mindset, you're comfortable owning services end-to-end in production

Familiarity with serverless architectures is a plus

Working knowledge of Go, auth protocols, OPA, Kubernetes and K6 is a significant advantage

Fluent in English, written and verbal; Norwegian is a plus

Relevant higher education or equivalent experience

What's in it for you?
Challenging tasks that allow you to grow professionally, competitive terms, a strong engineering culture, and good career opportunities. We offer good pension conditions, employee terms on DNBs products, insurance schemes, access to resorts in Norway, sports, cultural and other activities plus a wide range of discount schemes. In addition, knowledge and experiences are our most important assets, so you will have the opportunity to participate in courses and conferences such as JavaZone and NDC, both to build your own competency and to represent DNB externally. We also have flexible working hours, extra days off and reduced working hours from May to August (summertime).
