The role involves providing technical consulting and product guidance to partners integrating [Employer hidden] products, focusing on post-sale support, defining technical solutions, and managing integrations.

About the role

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

Through our API, we help partners to architect and build integrations to our world class-leading international finance products, which in turn improves [Employer hidden] Platform by increasing the capabilities of our public API.

This role will facilitate growth, troubleshoot and enhance the product offerings of [Employer hidden].

What will you be working on?

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

You'll be:

  • Acting as a trusted advisor and conduit between partners and [Employer hidden] 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.

You’ll also focus on proactively identifying common integration challenges faced by banks and addressing them through resources and support by:

  • Enhancing the integration experience for banking partners by developing comprehensive, user-friendly documentation, robust APIs, readily available SDKs with practical examples, clear code samples, and detailed reference implementations.
  • Working closely with the technical pre-sales team to provide expert technical guidance and support throughout the sales cycle, playing a critical role in securing new partnerships, demonstrating the technical expertise and showcasing the benefits of [Employer hidden]'s solutions through conducting technical presentations, demonstrations, and answering complex technical questions from potential partners.
  • Optimising and streamlining internal processes to enhance team capacity and overall efficiency. You would do this by identifying areas for process improvement, develop and implement new workflows, and leverage automation tools to reduce manual tasks to improve turnaround times.
  • Designing and developing innovative new features that expand the functionality of [Employer hidden]'s services and exposing these features through the public API, enabling seamless integration with partner systems to empower them to leverage the full potential of [Employer hidden]'s platform.
  • Diagnosing and resolving complex technical issues within the [Employer hidden] product stack, providing second-line support to the API support team and ensuring timely resolution of partner inquiries and technical challenges such as sharing in-depth knowledge and technical information of the platform and debugging.
  • Serving as the technical lead for complex partnerships and acting as a intermediary between [Employer hidden]'s engineering teams and the partner's technical teams to facilitate communication, coordinate technical activities, and ensuring alignment on technical requirements and solutions.
  • Establishing a robust feedback loop between the partner and [Employer hidden]'s product teams to gather valuable insights and drive continuous product improvements by  collecting partner feedback, analysing usage patterns, and working with product managers to prioritise and implement enhancements that meet partner needs.

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

This role offers you the opportunity to:

  • 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 [Employer hidden] 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.
