Job description

Overview

Are you a seasoned backend engineer who thrives on building scalable, event-driven systems in a cloud-native environment? Do you want to be part of a team shaping the infrastructure and core services behind a leading e-commerce platform? Then please go on reading.

To our client Whiteaway Group, we are looking for a Senior Backend Engineer for their tech headquarters in Aarhus.

Here you will join a product-centric company that has scaled rapidly across Scandinavia, driven by a strong digital mindset and a focus on delivering outstanding customer experiences.

Whiteaway Group is a digital-first retail company shipping household appliances across Scandinavia. What started as a fresh idea in the backroom of a Danish kitchen store in 2003 has grown into a leading player in the market. At the heart of this growth is a modern, autonomous tech organization committed to quality, experimentation, and delivery. The team in Aarhus consists of 40 people in the tech department, divided into 7 squads. Five of these squads include developers, product managers, UX-designers, and architects.

Responsibilities

• Design, implement, and maintain microservices using TypeScript/Node.js running in a cloud-native (AWS) environment. If you have experience in another backend language such as C#, Java, or Python, this is fine—you’ll just need to go through a short learning period to use Node.js/TypeScript.
• Lead architectural decisions and shape the future of the backend platform using domain-driven design and event-driven patterns.
• Collaborate closely with product managers, developers, and DevOps engineers to deliver reliable and maintainable systems.
• Ensure performance, security, and observability are first-class concerns in all solutions.
• Mentor peers through pairing, mob programming, and code reviews.

Qualifications

• Solid experience building scalable backend systems using backend stacks such as Java, Kotlin, Go, C#, Python, or Node.js/TypeScript—combined with a willingness to work with Node.js/TypeScript going forward.
• We value strong engineering fundamentals over specific prior experience with Node.js.
• Strong grasp of system design, DDD, event-driven architecture, and RESTful/async APIs.
• Hands-on experience with cloud platforms (preferably AWS) and containerized environments (Docker/Kubernetes).
• Familiarity with both SQL and NoSQL databases.
• Experience with architectural principles and microservice orchestration.
• Comfortable working in agile teams, taking ownership of features and mentoring others.
• Experience with high-traffic e-commerce or logistics systems is a plus but not required.

Benefits

• A flat, informal, supportive leadership culture where developers have real ownership.
• A culture centered on experimentation and continuous learning.
• Hackathons, pair, mob programming, and access to learning resources.
• Work-life balance, an amazing lunch, and great colleagues.
• Location in Skejby, offering free parking.
