Whether people and businesses are sending money to another country, spending abroad, or making and receiving international payments, Wise is on a mission to make their life easier and save them money. As part of our team, you will be helping us create an entirely new network for the world's money. For everyone, everywhere.

Job Description

Wise Platform helps banks, software companies, and large enterprises leverage Wise's infrastructure to offer their customers world-class payment products. We’re a cross-functional team across sales, account management, product, engineering, compliance, analytics, and many other functions. We’re based across the world - from New York to London, to Singapore, and beyond.

We’re looking for a Product Engineer to join our growing API Experience team in London. The API Experience team is responsible for some of the most critical systems at Wise, the public API gateway and authorization systems used by our own systems and our partners. Our goal is to increase efficiency during integration with our platform by setting the gold-standard for intuitive, consistent, enterprise-ready APIs, and to enable seamless integration of those APIs with developer-friendly tools.

• Operational Efficiency and Reliability: Enterprise customers require APIs that are exceptionally reliable and efficient. Banks and financial services handle large volumes of sensitive transactions that must be processed accurately and quickly.
• Robust Security and Compliance: Financial grade security measures ensure that our enterprise partners can trust our platform. Compliance with industry regulations and standards also reduces the risk of legal issues.
• Scalability and future-proofing: Our APIs need to be designed to handle increasing loads without performance degradation, ensuring that companies can scale their operations smoothly.
• Competitive Advantage: A high-quality API can be a significant competitive differentiator.

As part of this role, you will:

• Learn about the challenges for our large API partnerships, and help solve them.
• Balance practical challenges in improving API design, implementation and best practices.
• Work across the tech stack, supporting on frontend and infrastructure.
• Assist partners in the implementation phase, defining technical solutions and documenting requirements.
• Participate in feature definition, prioritisation, and long-term strategy planning with the team.
• Collaborate with Implementation Managers, Product Managers, and other Engineers.
• Improve integration experience through documentation, APIs, SDKs, code samples, and reference implementations.
• Design and develop new features for Wise services and expose them on the public API when needed.
• Travel to meet with our engineers in Tallinn as well as other travel opportunities.

Who you are

We are fully aware that it is uncommon for a candidate to have all skills required and we fully support everyone in learning new skills with us. So if you have some of those listed below and are eager to learn more we do want to hear from you!

• Extensive experience in designing, building and maintaining public APIs for commercial purposes.
• Hands-on experience designing, developing, and deploying scalable backend microservices using Java and Spring Boot.
• Familiarity with common design patterns and architectural principles.
• A strong independent thinker who is also eager to accept feedback and collaborate.
• Considers more than just customer impact; also the long term financial and architectural costs of the solutions we build.
• Puts the customer above technology, while finding ways to leverage technology to improve experience.

Nice to have:

• Understanding of payments systems, financial technology, and the complexities of funding, settling, and sending payments internationally.
• Ability to design, optimise, and maintain databases using a variety of technologies, particularly relational databases (MySQL, PostgreSQL).
• Can communicate complex technical concepts to a non-technical audience.

What do we offer:

We believe teams are strongest when they are diverse, equitable and inclusive. We’re proud to have a truly international team, and we celebrate our differences. Inclusive teams help us live our values and make sure every Wiser feels respected, empowered to contribute towards our mission and able to progress in their careers.
