Delivery & execution — Build, ship, and maintain backend services and web interfaces in production. — Deliver new features end to end — from requirements to release. — Optimize applications for performance, scalability, and reliability. — Ensure high code quality through reviews, testing, and clean architecture.
Quality, testing & reliability — Write and maintain unit, integration, and end-to-end tests. — Improve test coverage and reliability of existing systems. — Identify performance bottlenecks and drive optimization initiatives. — Ensure secure coding practices and basic application security.
Collaboration & product delivery — Partner with product managers, designers, and engineers to deliver business outcomes. — Translate requirements into technical solutions with clear trade-offs. — Contribute to planning, estimation, and iterative delivery in Agile environments. — Share technical context and documentation with the team.
Team contribution & growth — Mentor junior engineers and support technical growth within the team. — Participate in technical discussions and continuous improvement initiatives. — Stay current with modern JavaScript, Node.js, and web development practices.
