Job description

Do you want to build digital products that make a meaningful difference across Novo Nordisk's global operations? Are you a highly experienced software engineer who enjoys working across the full technology stack while helping shape the future of modern cloud-based solutions? If so, this could be your opportunity to join a team where your technical expertise will directly influence how thousands of colleagues plan and operate critical business activities every day.

Your new role

As a full-stack developer for NN Planner, you will help shape, develop, and drive the implementation of digital solutions in Planning Solutions, ultimately addressing some of the biggest business opportunities we have at Novo Nordisk. You will join a small agile team that develops Novo Nordisk’s workforce planning solution, focused on improving efficiency across production, QA, QC laboratories, warehouses, and other functions. We do this using a tech stack consisting of AWS services, a containerised Python backend and a frontend web application using React/TypeScript. Our application has more than 4,000 users and we expect our user base to double within the coming years.

Your Responsibilities Will Include

• Contribute to a production Python backend, balancing ongoing feature delivery, quality improvements, and the migration from legacy patterns to modern architecture.
• Build and evolve our frontend application by developing maintainable, type-safe React/TypeScript solutions, shaping frontend architecture and API boundaries, and ensuring a responsive and reliable user experience as the platform scales.
• Write and review production code daily, helping to define best practices for how we build, test, and deploy software.
• Evolve our data layer by improving schema design, query performance, and migration strategies in PostgreSQL using SQLAlchemy 2.0 and Alembic, including zero-downtime migrations in live production environments.
• Modernise legacy systems incrementally using approaches such as the Strangler Fig pattern, while maintaining uninterrupted service for users.
• Manage and evolve our AWS infrastructure (ECS Fargate, ECR, ALB, S3, IAM, and SSM) using Terraform, with a strong focus on reproducibility and consistency across environments.
• Drive a strong quality culture by maintaining comprehensive automated testing with pytest, including unit, integration, and BDD-style tests that support compliance requirements within our QMS.
• Share knowledge and support the growth of fellow engineers by contributing meaningful code reviews, strengthening technical practices, and fostering a culture of continuous improvement.

We build end-to-end digital solutions on AWS using Python and React/TypeScript, supported by CI/CD pipelines for continuous delivery. As part of Novo Nordisk’s digital transformation journey, we encourage you to challenge existing approaches, drive innovation, and help raise engineering standards across the organisation.

Your new department

Planning Solutions is part of the Enterprise Platforms organisation at Novo Nordisk — the team responsible for the digital platforms that power Novo Nordisk's operations at scale. We sit at the heart of the company's most business-critical applications, building and maintaining the solutions that thousands of colleagues rely on every day.

As a member of Planning Solutions, you will join a team dedicated to driving the development, adoption, and scaling of our digital planning solutions. We work closely with the business to ensure our platforms not only meet today's needs but are built to grow with the organisation. This means working on a product that is already in the hands of thousands of users and scaling fast.

We offer a modern working environment, a high bar for technical quality, and the satisfaction of seeing your work make a real impact across Novo Nordisk's global operations.

Discover the cutting-edge technologies behind Novo Nordisk's life-changing innovations at TechLife at Novo Nordisk. From AI to quantum computing, our digital experts push boundaries and make a tangible impact on lives across the globe. You don't want to miss it.

Your Skills And Qualifications

To succeed in this role, you bring strong full-stack engineering experience combined with a passion for building scalable digital solutions. You are comfortable working across technologies, influencing technical direction, and balancing long-term improvements with day-to-day delivery.

We Imagine That You Have

• 10+ years of professional software engineering experience, including substantial experience in senior roles, with a strong track record of building, operating and incrementally modernising production systems.
• Deep hands-on expertise in Python, alongside strong React and TypeScript experience, with sound full-stack architectural judgement about how responsibilities should be distributed across frontend, backend and supporting services.
• Strong PostgreSQL and relational database expertise, covering data modelling, schema design, query optimisation, indexing, transactions and data integrity, including experience safely evolving schemas in live production environments.
• Practical experience designing and operating cloud-native applications, ideally on AWS, using Docker, infrastructure as code such as Terraform, and CI/CD practices that support safe, continuous delivery.
• Strong testing and code review discipline across unit, integration and end-to-end testing, with tests that clearly reflect user and business requirements and enable confident changes to existing applications.
• A pragmatic, collaborative approach: favouring simple, maintainable solutions, communicating technical decisions clearly, helping other engineers develop, and applying sound judgement when using AI-assisted and agentic development tools.
