Develop and evolve RESTful APIs and web applications with a strong focus on scalability, maintainability, and performance.
Contribute to architectural decisions, prototype solutions where needed, and help separate major components and subsystems as products evolve.
Partner effectively with Product, QA, DevOps, Security, and other engineering teams to ensure smooth delivery of working software into production.
Champion code quality through thoughtful code reviews, automated testing, documentation, continuous improvement of engineering practices, and sensible use of AI tools for coding, debugging, and prototyping with appropriate human validation.
Mentor other engineers, share knowledge across the team, and help raise the bar on technical execution and delivery discipline.

Strong communication skills and the ability to work effectively with both technical and non-technical stakeholders.
Ability to mentor peers, contribute to engineering standards, and help break down larger initiatives into executable work.
Working knowledge of SQL and data modeling, with the ability to reason about application performance and persistence-layer design.

Preferred Experience/Skills

Experience working with AWS-based systems and modern cloud deployment patterns.
Experience with message queues, asynchronous processing, or event-driven integration patterns.
