About the role

As a Software Engineer at Madden, you'll own features end to end - following a problem wherever it lives and fixing it there, rather than handing it off at a service boundary. The work is backend-weighted and that's where you'll spend most of your time, but some of it will land in the frontend, and you should be comfortable going there when a feature or a bug takes you there. Madden's tech team is a collaborative, tight-knit group where creativity, teamwork, and initiative are highly valued. We foster a culture where learning, personal growth, and mutual support are encouraged.

Your tasks will include:

• Collaborating with leadership, product design, and other developers to improve solutions.

• Building and owning our backend (Golang, Postgres, ClickHouse), and the frontend on top of it (React, TypeScript).

• Working with data at scale - designing the schemas, queries, and pipelines that keep large volumes of retail and e-commerce data fast to query as our customers grow.

• Building LLM-powered features in the product - assistants, agents, and natural-language querying over customer data - and taking them from prototype to something we can run in production.

• Sharing your expertise in architectural discussions, technical discovery, and daily conversations with your team members.

• Optionally, contributing to cloud infrastructure (GCP) and our forecasting and predictive modelling work, depending on your experience.

Location: Office-first, in central Stockholm. Close collaboration and shared problem-solving are core to how we work, so the default is being in together - with flexibility when life requires it.

Who we're looking for

• Someone who works well in a small team and drives their own work - comfortable taking ownership and moving things forward without being asked, and equally comfortable pulling others in when that gets to a better answer.

• An interest in building scalable applications that handle large data sets.

• Curiosity about applying LLMs in real products - where they work, where they don't, and what it takes to make them reliable enough to put in front of a customer. Hands-on experience is welcome but not a requirement.

• Several years of professional experience building and running backend services in production. We care more about what you've built and shipped than the exact number of years.

• A degree in computer science, engineering, or a related field - or equivalent knowledge acquired another way.

• Depth on the backend, plus enough frontend to find your way around. You've worked in a modern component framework at some point and can take on a React and TypeScript task - it doesn't have to be where you're strongest, but it shouldn't be new to you.

• Bonus: an interest in consumer retail, e-commerce, and analytics.

Why join Madden Analytics?

• You'll contribute to solving critical problems for leading brands and retailers.

• Be part of a supportive, highly experienced team that values knowledge sharing and continuous learning.

• Join a startup with strong traction and exciting growth opportunities, where your contributions directly influence the product's direction.

• We have a dynamic and creative work environment with a focus on quick iterations and a test & learn/fail fast mindset for learning and improvement.

• Flexible hours, and a pragmatic attitude to the days when life gets in the way.

• Competitive compensation, including salary and stock options.
