Lead Engineer - Full Stack
Copenhagen
We're helping our client hire a Lead FullâStack Engineer to join a globally distributed engineering organisation building real, productionâcritical platforms used daily by customers and partners across multiple markets.
This is a productâcentric environment with longâlived systems, modern engineering practices, and meaningful technical ownership. You'll work on a large, cloudânative omnichannel platform supporting web, transactional, and operational workflows at scale.
How engineering works
* Pragmatic delivery: iterative development, measurable outcomes, and intentional refactoring
* Writtenâfirst culture: design docs and async communication to align teams across locations
* Autonomy with standards: clear technical guardrails without bureaucracy
* Customer proximity: engineers regularly see their work live in realâworld environments
The role
As a Lead Engineer (Full Stack), you'll play a key role in shaping the future of a suite of Reactâbased applications, ranging from bespoke customer experiences to highâtraffic B2B and B2C platforms.
This is a handsâon leadership role combining deep technical work with influence across teams. You'll own frontend architecture, raise engineering standards, and collaborate closely with Product, Backend, and Delivery stakeholders.
What you'll do
* Lead and mentor multiple teams delivering complex web applications, dashboards, portals, and userâfacing platforms
* Own frontend architecture across new and existing React applications
* Define shared foundations: design systems, component libraries, tooling, CI/CD pipelines, and modern AIâassisted developer workflows
* Improve engineering quality through strong design docs, code reviews, documentation, and retrospectives
* Partner with Product and business stakeholders on roadmap planning and delivery
* Make architectural decisions that balance shortâterm delivery with longâterm maintainability
* Influence API contracts, performance strategies, authentication, and security patterns across the stack
What we're looking for
* 3+ years of handsâon React experience, ideally in complex or largeâscale environments
* Proven experience in a technical leadership capacity (formal or informal)
* Strong understanding of API consumption and design patterns
* Excellent communication skills and comfort working crossâfunctionally
* Demonstrated endâtoâend ownership, from problem definition to production and monitoring
* Experience coordinating work across multiple teams or systems
* Full professional proficiency in Danish and English
Nice to have
* TypeScript
* Experience with commerce, transactional, or dataâheavy platforms
* GraphQL and/or REST APIs
* Cloudânative runtime experience
* Observability and monitoring tooling
* Security and performance awareness
* Familiarity with modern React tooling and ecosystem
* Exposure to AI / LLMâassisted development workflows
What's on offer
* International engineering environment
* Seniorâlevel scope with real technical and organisational influence
* Modern, cloudânative technology stack
* Competitive compensation package including pension and benefits
* Strong social culture with team events and shared activities
* Opportunity to shape both the role and the platform as the organisation grows
