Backend Engineer

Wise is seeking senior product engineers for its Grow squad, a team aiming to make the Wise Account the primary financial hub for customers. Although the listing is titled Backend Engineer, the content describes product-minded engineers who own what they ship and help shape what gets built alongside product managers, designers and analysts. Two streams of work are described: one scaling an existing product and one building from zero.

In the Assets stream, customers hold their balances in a current-account-style product that pays daily returns from government rates and global indices, while keeping instant access and no fixed terms. The product is already running in four markets spanning Britain, the EU, Singapore and Australia. The engineering task is to architect a high-availability yield engine handling very large balances, keeps custody protected and maintains near-instant liquidity.

The Investments stream starts from scratch. The goal is to let customers buy individual shares and run tax-efficient long-term pots such as ISAs and SIPPs inside the app. The engineer sets the technical base, brokerage infrastructure and trading screens from the beginning, and helps define the long-term code for that new pillar.

Strong fits will have shipped web apps and distributed systems into production, write clean, well-tested and fast code, explain technical concepts to non-engineers, and split large projects into steps that deliver customer value. Java, Spring Boot and message platforms such as Kafka are an advantage, though candidates still learning them are encouraged to apply. Starting pay is £87,500 to £111,000 plus RSUs. Relocation support is not provided, so only candidates already based locally are considered, though a transfer of visa sponsorship can be supported for them.
