As part of our team, you will be helping us create an entirely new network for the world’s money.

We are looking for a Senior Solutions Engineer to join our growing Wise Platform team in London. The Wise Platform team works with top tier global financial institutions and major tech companies to offer Wise products and services directly to their customers.

This role will facilitate growth, troubleshoot and enhance the product offerings of Wise.

As part of the Wise Platform team, you’ll play a key role in providing technical consulting and product guidance to top tier banks and other partners integrating Wise into their products, primarily in a post‑sale capacity.

• Acting as a trusted advisor and conduit between partners and Wise where your technical expertise will enhance the product development and integration process.
• Defining technical solutions, gathering requirements and supporting the delivery of integrations tailored to each partner’s needs.
• Supporting partners during the bespoke implementation collaborating across teams to ensure smooth delivery.
• Managing multiple integrations in parallel and navigating ambiguity.

• Enhancing the integration experience for banking partners by developing comprehensive and user‑friendly documentation, robust APIs, readily available SDKs, practical examples, clear code samples, and detailed reference implementations.
• Working closely with the technical presales team to provide expert technical guidance and support throughout the sales cycle, playing a critical role in securing new partnerships by demonstrating the technical capabilities and benefits of Wise's solutions.
• Optimizing and streamlining internal processes to enhance team capacity and overall efficiency.
• Designing and developing innovative new features that expand the functionality of Wise's services and exposing these features through the public API.
• Diagnosing and resolving complex technical issues within the Wise product stack, providing second‑line support to the API support team.
• Serving as the technical lead for complex partnerships, acting as a crucial intermediary between Wise's engineering teams and the partner's technical teams.
• Establishing a robust feedback loop between the partner and Wise's product teams to gather valuable insights and drive continuous product improvements.

You should be someone who can think holistically about the ecosystem, while also being hands‑on when required.

• Define your own path to success, with autonomy to create and drive your vision forward.
• The opportunity to shape and innovate financial products across regions.
• Identify problems and unlock opportunities for Wise and its partners through technology solutions.
• Inspire teams internally and externally with your ideas, knowledge, and proactive attitude.
• Travel to work with teams in Tallinn and London, as well as visit partners across the EMEA region.

If you thrive in a fast‑paced, innovative, and at times chaotic environment and are excited about working with a diverse team to shape the future of financial integrations, this could be the perfect role for you.

• Strong problem‑solving and organisational skills, able to handle ambiguity and competing priorities.
• Familiarity with common design patterns and architectural principles, including domain‑driven design (DDD), event‑driven architecture (EDA), and microservices architecture.
• Familiarity with Java (Spring), Kubernetes, AWS, and service mesh architectures and technologies such as RESTful APIs, API design, Swagger, OpenAPI, and OAuth2.
• Familiarity and working experience with relational databases (e.g. MySQL, PostgreSQL) and non‑relational databases (e.g. MongoDB, Cassandra).
• 6+ years in customer‑facing engineering roles ideally within financial services or similar domain.
• Clear communication and strong interpersonal skills.
• Customer‑centric approach.
• Ability to convey technical concepts to non‑technical audiences and work effectively with both technical and non‑technical stakeholders.
