Every day, billions of NOK move through our systems, and our engineering teams build the foundations that make those experiences possible. Our team The Channel Capabilities tech family consists of three platform teams responsible for the shared foundations behind DNB's digital customer channels: Nucleus – DNB's modern web platformDigital Platform – foundational platform capabilitiesEufemia – DNB's design system We're looking for experienced Software Engineers to join the Nucleus team and help shape the future of web development at DNB. What We Build Nucleus provides the core capabilities that enable modern web development across the bank. Rather than building customer-facing features, we build the platform that hundreds of engineers rely on to deliver them. Our platform includes: A serverless runtime platform on AWS that composes independently deployed microfrontends through self-service configuration.Frontend discovery and runtime orchestration services.Authentication and authorisation integrations.Shared tooling, libraries, and CI/CD workflows that establish the golden path for development, testing, deployment, observability, and code quality.Platform abstractions that support multiple brands, products, markets, and authenticated customer journeys. Our work spans frontend, backend, infrastructure, developer experience, and cloud platform engineering. We solve problems that require balancing performance, reliability, security, developer productivity, and long-term maintainability. The platform serves multiple types of consumers: engineering teams building applications, product teams delivering customer journeys, and ultimately millions of end users. Building solutions that work well for all of them is what makes the role both technically challenging and rewarding. Although our platform is technology-agnostic by design, our current ecosystem includes React, TypeScript, Node.js, Vite, AWS, Terraform, and modern cloud-native technologies.
