Senior Software Engineer (Lisbon)

We are looking for a talented senior software / full-stack engineer to help our development team build state-of-the-art product offerings on top of our massive retail dataset.

With many of Europe’s biggest names in retail as our customers, we’re a young company experiencing rapid growth and your work will have an immediate impact. Our ideal candidate is engineering driven, deeply experienced across all layers of the stack and excited to bring their knowledge to our team.

Qualities that would make you a great fit for this role:

  • You believe passionately in code quality, the principles of DRY and leveraging best practices to deliver robust, performant, maintainable code.
  • You are interested in large datasets, building applications on top of this data and helping our data scientists turn their algorithms in to products that amaze our customers.
  • You enjoy working on and solving design challenges across all areas of the stack (from data pipelines and deployment orchestration through to API development and front-end work).
  • A love of and experience with Python – we use it extensively!
  • Advocate of modern tooling to automate “all the things” (CI/CD, Terraform, Ansible, Docker).
  • Familiar building on top of cloud providers (we use AWS) and using agile development methodologies (SCRUM & KANBAN).
  • Collaborative in nature and comfortable taking up the role of Product Owner (you love structuring issues, keeping an overview of the work involved in a project and communicating this with various stakeholders to help the company prioritise).

If this sounds like the perfect job, we’d love to hear from you! Our interview process doesn’t involve white boarding, riddles, or games – we want to understand how you’ll fit into our team and contribute to our mission, not how well you recall syntax under pressure.
