The role in a nutshell

A Senior Software Engineer in UNiDAYS is a hands-on software development role focused on building innovative solutions to delight our members and drive product success in a fast-paced company.

It’s more than just lines of code; we are looking for a commercially-minded Senior Software Engineer who can bridge the gap between user needs and business goals. You will have the ability to build resilient, cost-effective solutions and navigate evolving market demands.

You will be working closely alongside the rest of our product and engineering teams while defining, refining, building, and measuring the impact of the solutions you implement. These may be across our portfolio of marketplace products, identity products, or elsewhere as the business grows.

In order to be successful in this role, you will need to translate user needs into market-winning solutions, all while navigating technical challenges and ensuring commercial viability.

You will need an inquisitive mind as we continue to work with bleeding-edge technologies and split our core business logic out into Kotlin Multiplatform libraries (Note that prior experience with KMP is not required; on-the-job training/learning is fully supported).

  • Deliver impactful features with a pragmatic approach
  • Use your technical knowledge and experience to solve problems in the most appropriate way - balancing risks, constraints, user needs, and business needs
  • Championing user-centric solutions with a keen eye on market fit and profitability
  • Representing Android concerns within the team
  • Be an active contributor and promoter of the wider Android and Mobile team
  • You will work closely with your teammates to ensure the direction and standards set out for the team are delivered
  • Monitoring platform/feature performance & crashes, flagging issues, and writing tickets to address
  • Contribute to the design and architecture of software systems, ensuring that they are scalable, efficient, and maintainable
  • Collaborating with external stakeholders and peers
  • Support and challenge software engineers through pairing, knowledge sharing, documentation, and mentoring
  • From time to time - support our interview process by attending interviews, task assessments, and candidate feedback
