About the role

What You Will Do

As a Senior Solution Engineer you are responsible for defining Klarna product solutions for our biggest merchants and partners based on their needs. You work closely with the sales team to provide technical product knowledge and support during the sales process.

You are a trusted advisor for both internal and external stakeholders and own all of the technical aspects of the pre-sales process as well as delivery of solution proposals to clients. This includes leading product demos and presentations, providing technical input into customer proposals and translating product and business requirements into innovative solutions.

When a customized solution requires development, the Senior Solution Engineer will be the one to define the needs of the client, architect the solution together with the client, and lead the realization effort.

Who You Are

  • Minimum 6 years experience in working with and/or implementing technical solutions.
  • Experience integrating with or supporting Payment Service Providers (PSPs), gateways, or acquirers.
  • Experience leading technical deep-dives and pre-sales discussions and managing client expectations.
  • Outstanding problem solving ability, eagerness to learn and curiosity.
  • Adaptable attitude and personality that is ready for continuous change.
  • Familiar with at least one modern back-end language (Java, TypeScript/Node.js, C#/.NET or Go) and very comfortable with API patterns and design (REST, webhooks, OAuth) for e-commerce/checkout integrations.
  • Experience with modern payment tech stacks (eComm platforms, PSPs/gateways, orchestration layers, etc).
  • Some sales or account management experience.

Awesome to Have

  • Proud of the way you can communicate complex solutions to both technical and non-technical audiences of senior stakeholders.
  • Familiarity with card network–style concepts (settlement, tokenization, disputes, transaction monitoring) is a plus.
  • Not only good at the tech stuff but can easily present your solutions together with the responsible Account manager to the client.
  • Excited to work in a rapidly evolving ecosystem with constant change in priorities, partners, and technical standards.
  • Thrive in an environment where you get the opportunity to use your quick and creative mind.
  • High enthusiasm and drive, which will help you and your team to deliver great solutions.
  • Humble and committed person with a desire to always exceed expectations.
