Backend Developer (~75 - 100 k/y, Helsinki-FI)
Join our interesting customer development project as a Senior Developer!
This is a long-term project (2–3 years, possibly longer) focused on a comprehensive renewal of the bank's interface architecture – a technically demanding initiative requiring a highly skilled professional.
You will join a team of around 40–50 people divided into four squads. Each squad consists of iOS and Android developers, backend developers, QA, squad leads/Product Owners, and designers. You will most likely join the Banking squad or the Foundation team, which handles architectural and component-level changes.
The role involves collaboration with the core banking system provider and the bank itself. Due to the nature of the project, security clearance will be required, with the expected start in August 2025, after clearance completion.
We are seeking a consultant who can raise the overall level of the team, not just through technical skills, but also by being proactive in documentation and communication. You should be comfortable producing clear technical documentation (such as API usage guides or possibly sequence diagrams) and actively contributing to architectural discussions.
