• Break down large, ambiguous problems into deliverable increments and sequence them with product partners.
• Set and enforce engineering standards for code quality, testing, security, observability, and operational readiness.
• Own performance and scalability of your area: profile, find bottlenecks, and optimize under production load, including real-time data streaming.
• Mentor intermediate and junior developers through code reviews and pairing.
• Partner with Product, UX, Enterprise Architecture and Security on scalable, resilient and compliant designs.
• Take part in incident response and on-call rotations, and drive blameless post-incident reviews to closure.

• Proven experience with RESTful APIs and microservices or service-oriented architectures.

• Experience leading technical initiatives across several developers without formal authority.
• Strong communication skills in English, able to explain technical trade-offs to engineering and cross-functional audiences.
• Bachelor's degree in Computer Science, Software Engineering or a related field, or equivalent practical experience.
