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.
As a Lead Software Engineer, you will be responsible for leading the development and optimisation of our software applications, with a strong focus on scalability, reliability, and performance. You will be at the helm of driving technical decisions, managing projects, and ensuring the delivery of high-quality code. This role requires a blend of technical expertise, leadership abilities, and a forward-thinking approach to handle challenges effectively and contribute to the strategic direction of our engineering efforts.

  • Database Mastery: Show expert-level knowledge of databases, especially PostgreSQL and DynamoDB, including design, optimisation, and management.
  • Project Leadership: Lead projects with a self-driven approach, managing stakeholders, anticipating technical debt, and crafting a technical roadmap to navigate and mitigate these challenges efficiently.
  • Mentorship and Collaboration: Mentor colleagues, enhancing team capabilities, and fostering a collaborative environment. Conduct demos, presentations, and contribute to the creation of comprehensive documentation.
  • Quality and Testing: Uphold a strong commitment to quality through extensive knowledge of testing methodologies and an unwavering attention to detail.

To succeed in this role, we think you should have:

  • Demonstrated experience in leading complex software projects.
  • A strong advocate for technical excellence, innovation, and continuous learning, with a track record of mentoring engineers towards achieving their career goals.
  • Exceptional analytical and strategic thinking skills, with the ability to balance short-term goals with long-term vision.
  • Proven ability to navigate complex organizational dynamics and build consensus among stakeholders with differing viewpoints.
  • Cross-Functional Collaboration: Work closely with other engineering teams, product management, design, and operations to ensure our technology stack integrates seamlessly
  • Strategic Technical Leadership: Play a pivotal role in shaping the technological direction of the team by contributing to the strategic planning and decision-making processes.

Some of the technologies you’ll get to work with:

  • JavaScript/ TypeScript
  • Node.js and Express.js
  • Jest
  • React and React Native
  • AWS, Splunk, Ansible, Terraform, Jenkins, Docker and Kubernetes
