- Designing and implementing APIs and integrations using REST and GraphQL.
- Architecting microservices and event-driven systems with clear service boundaries and strong observability.
- Leveraging AI-assisted development tools to improve development speed, quality, and documentation.
- Acting as a senior technical authority through code reviews, mentoring, and architectural guidance.
- Collaborating closely with product managers, designers, and stakeholders to translate business requirements into technical solutions.
- Taking ownership of delivery quality, production stability, and long-term system health.

- Hands-on experience with microservices and event-driven architectures.
- Strong API design experience (REST and GraphQL).

- Systems thinker with a pragmatic approach to problem-solving.
- Comfortable making architectural decisions and taking ownership of outcomes.
- Strong communicator, able to influence both technical and non-technical stakeholders.
- Natural technical leader who enjoys mentoring and raising engineering standards.
- Proactive, accountable, and delivery-focused.
