What you will do

• Own tasks end to end by clarifying requirements, exploring code and data, and choosing solutions without detailed specifications.
• Influence product decisions through user-journey and feedback analysis, balancing UX, product consistency, and implementation costs.
• Define acceptance criteria, plan testing and rollbacks, cover key and edge cases with automated tests, and ship small merge requests behind feature flags.
• Build full-stack features across UI, backend, and database layers, safely modifying an existing large codebase.
• Delegate work to coding agents, provide context, and verify generated code, tests, and results.
• Review colleagues’ changes and improve shared skills, agent workflows, and automated engineering checks.

Requirements

• Commercial development experience with PHP and Vue, React, or a similar frontend framework.
• Hands-on experience using coding agents in real-world projects.
• Strong engineering fundamentals in transactions and concurrency, idempotency, time zones, access control and data ownership, N+1 queries, and tables containing millions of rows.
• Ability to identify risks, flag blockers, and propose solutions.
• English proficiency at B1 level or above.
• Experience working across the stated backend, frontend, data, and infrastructure stack, including PHP 8.3, Slim 4, Symfony Components, RoadRunner, Vue 3, TypeScript, Pinia, Vite, MySQL, Redis, ClickHouse, RabbitMQ, GitLab CI/CD, Docker, and Kubernetes.
