About the role

We are looking for a Senior Software Engineer to join our Business Expense Management team. You’ll own everything related to the process of tracking, submitting, and managing business expenses as smoothly and hassle-free as possible. We help businesses collect receipts and information about expenses in the most convenient way, so our customers can focus on their work. You’ll have an opportunity to build solutions that help employees easily submit their expenses, ensure compliance with company policies, make expenses transparent for monitoring and keep bookkeeping clean.

How we work

For everything we do, we keep our customers' needs in mind. To provide the best experience for businesses, we prioritise projects using deep research based on the data, collect the feedback from customers and learn from our mistakes. At Wise, we believe in independent teams where we define our priorities ourselves and everyone can come up with ideas and suggestions.

We operate on a strong belief in automation, programmatic implementation, and reusable design. We’re looking for people who can step back and think holistically about the ecosystem, but also follow through and help implement the design; drawing on the resources across the rest of the global product tribe.

We need to sustain this growth by continuously iterating on the services we run, with a focus on availability, security, and ease of use. We’re looking for an engineer with relevant experience who can analyse complex requirements and deliver simple solutions to help our teams achieve our mission with speed and confidence.
