- Mentoring engineers across teams and helping maintain a high technical bar organization-wide
- 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 teams
- 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 team services
- Participating in on-call rotations for your team and responding to incidents as necessary
- Focusing primarily on backend applications, while being open to contributing to mobile and frontend development according to business needs
We are looking for a person who has
- At least 8 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 across multiple teams, even without direct authority
- Experience mentoring senior engineers and raising the technical bar across organizations
- 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
