As a Senior Software Engineer , you will play a key role in leading the design and evolution of large-scale distributed systems within your team, and influencing technical decisions in close collaboration with adjacent teams. While we value experience with our tech stack, we are confident that engineers who are eager to learn will be successful here — and we will teach you Clojure as our main backend language.

You will build and evolve:

• Leading technical direction for your team and partnering with adjacent teams to keep solutions aligned with our architecture and business strategy

• Driving pragmatic innovation while ensuring resilient, secure, and flexible solutions that scale across products and geographies

• Mentoring engineers within and around your team and helping maintain a high technical bar

• Writing, testing, instrumenting, documenting, and maintaining high-quality code

• Pairing and participating in code reviews to support the growth of others in and around your team

• Collaborating closely with Product, Design, and Engineering leaders to build new end-to-end experiences

• Ensuring comprehensive observability, performance monitoring, and robust error handling across your team’s services

• Participating in on-call rotations for your team and responding to incidents as necessary

• Focusing primarily on backend applications

We are looking for a person who has

• At least 6 years of experience developing digital products in complex environments

• Deep expertise in distributed systems , microservices architecture , and cloud technologies

• A proven track record of designing and delivering large-scale systems that serve thousands or millions of users

• A strong background in object-oriented or functional programming languages , with the ability to work across multiple languages

• Demonstrated ability to lead technical initiatives end‑to‑end within a team and in collaboration with partner teams

• Experience mentoring engineers and raising the technical bar in their teams

• Practical knowledge of agile software development methodologies and prior experience with CI/CD

• Strong communication skills to identify and prevent risks, and explain trade-offs clearly to both technical and non-technical stakeholders

• Advanced English skills
