The mission for this role

Our engineers are embedded in cross-functional product squads, collaborating closely with Product, Design and Data Science to discover, design, and deliver their squad’s quarterly goals. Engineers work to deliver services and features that will have real impact on our OKRs and our business. They care about shipping high quality, readable, code and reliable, scalable, systems. Collaborating with stakeholders across the business, our engineers care about our customers’ experience of our platform, and strive to make sure our product meets their needs.

Our engineers are working on a product vision that will take our business to the next level, including:

  • Developing a brand new self serve experience for our customers to enable them to move faster.
  • Increasing engagement by allowing our customers to do more with their insights (for example by allowing them to track and compare multiple data sets over time).
  • Expanding the range of the audience our customers want to reach and using ML to improve the quality of the answers the audience gives.

On top of squad work, our engineers play an active part in the vibrant backend chapter, collaborating with other backend colleagues across the whole of R&D to improve the way we work as a function. Engineers contribute by: maintaining coding standards by pairing with colleagues; reviewing (and contributing towards) proposals for new services; taking part in communal learning sessions eg mob programming or tech talks; mentoring others. 


Your focus will be to...

  • Work within a squad collaborating with the whole team to identify and create best-in-class products.
  • Deliver features regularly, be comfortable with ambiguity, and push for code quality while balancing pace vs perfection.
  • Participate in planning, stand-ups and retrospectives.
  • Explore innovative ways to solve problems, and become an expert in complex systems.
  • Design highly efficient architecture that scales around user demand.
  • Play an active part in our backend chapter, reviewing colleagues’ code, participating in chapter discussions, creating and reviewing proposals for new services, working to improve our operational excellence.


We’d love to hear from you if…

  • You have expertise in either Golang or Java or any similar language.
  • You have expertise in building and maintaining a distributed, event-driven architecture.
  • You have expertise in developing, testing & debugging  complex systems.
  • You have experience with databases: PostgreSQL / mySQL / DynamoDB / Redis.
  • You have experience with infrastructure technologies: Kubernetes, AWS, Kafka, Terraform.
  • You are a team player: collaborative, self-motivated, creative, entrepreneurial & thoughtful style.
  • You have experience of working within a deeply complex domain: you will enjoy the challenge of simplifying the collection, analysis, and presentation of, complex data sets for our users.
  • You enjoy solving complex data & architecture problems efficiently.
  • You are a confident and thoughtful communicator, both verbally and in writing, able to adapt your style to different audiences and in different contexts.
  • You are curious and possess rigour in your way of thinking, using data and your experience to make informed and balanced decisions.
  • You like to contribute towards a culture of improvement and learning - continually learning yourself, and also passing on your experiences on to others. 

We care deeply about building a place where engineers love to work. You can read more about our approach in our Engineering Handbook and our R&D blog.
