Posted on Saturday, August 26, 2023
We are on a mission to liberate humanity from all the meaningless time spent managing their purchases and finances, so they can do more of what they love. Klarna was founded on a bold belief: that people are capable of achieving the extraordinary, even when faced with the seemingly impossible. Our journey has been one of continuous learning, facing immense challenges head-on, dedicating countless hours of hard work, and never wavering in our commitment or resilience - and now we are looking for individuals to join us on our journey and contribute to our mission.
Klarna provides Shopping & Marketing services to its Partners to improve their customer journeys, through a unique Web SDK and via several backend APIs. As a Software Architect or Engineering Manager, you are responsible for the partner’s experience when integrating and using this API. You strive to simplify the integration from a Partner’s point of view and by working together with several product teams. You make sure that new products are not introducing new complexities for our Partners. You work directly with product owners, solutions engineers and technical writers to improve the experience of our partners.

Key Responsibilities:

  • Architectural Leadership: Design, develop, and evolve the overarching API architecture, ensuring it aligns with the Klarna's technology strategy, scalability needs, and future business objectives.
  • Solution Design: Create comprehensive API specifications, including endpoints, data models, authentication/authorisation mechanisms, and error handling, to ensure optimal functionality, security, and performance.
  • Technical Strategy: Collaborate with stakeholders to define the technical direction for API development, selecting appropriate technologies, frameworks, and tools that align with industry best practices.
  • Scalability and Performance: Define strategies for scaling APIs to accommodate increasing user loads and ensuring high availability, low latency, and optimal response times.
  • Security and Compliance: Implement robust security measures, including data encryption, authentication, authorisation, and access controls, to ensure the confidentiality and integrity of user data. Ensure compliance with relevant industry standards and regulations.
  • Documentation: Create comprehensive documentation for APIs, including usage guidelines, integration procedures, and code samples, enabling internal and external developers to effectively utilise the APIs.
  • Code Quality and Review: Lead code reviews and provide technical guidance to the development team to maintain high coding standards, optimise performance, and address architectural concerns.
  • Integration Strategy: Collaborate with cross-functional teams to define integration strategies, ensuring seamless communication between various systems and services.
  • Problem Solving: Identify and address technical challenges, performance bottlenecks, and architectural limitations proactively, proposing innovative solutions to complex problems.
  • Mentorship: Provide mentorship and guidance to junior developers, fostering their professional growth and encouraging best practices in API design and development.

Who you are:

  • Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field (or equivalent work experience).
  • Proven experience as a Software Architect or similar role, with a strong focus on designing and developing APIs.
  • In-depth understanding of API design principles, RESTful architecture, GraphQL, and other relevant API paradigms.
  • Proficiency in programming languages such as Java, Python, Node.js, or similar.
  • Hands-on experience with API management tools, versioning, and documentation platforms.
  • Strong knowledge of security protocols, authentication, authorisation, and data protection.
  • Familiarity with cloud technologies and microservices architecture.
  • Excellent problem-solving skills and the ability to think strategically while also being detail-oriented.
  • Strong communication and collaboration skills, with the ability to work effectively across diverse teams.
  • Experience with Agile methodologies and continuous integration/continuous deployment (CI/CD) pipelines
  • Demonstrated track record of successfully delivering complex API projects from conception to production.
