• Collaborate closely with product, design, and QA teams to deliver robust solutions
• Break down complex initiatives into well‑defined, actionable tasks and guide implementation
• Monitor systems and participate in a rotating on‑call schedule when required
• Promote secure coding practices and ensure code is free from known vulnerabilities
• Document architecture, decisions, and processes to support team‑wide knowledge sharing
• Mentor junior and mid‑level engineers and contribute to a strong engineering culture

Requirements

• 5+ years of professional experience with PHP (7.4 / 8+)
• 3+ years of hands‑on experience with the Symfony framework
• Strong understanding and practical use of design patterns
• Solid experience with unit and integration testing (PHPUnit, Behat, or similar)
• Hands‑on experience with Test‑Driven Development (TDD)
• Familiarity with static analysis tools (PHPStan, Psalm, or similar)
• Strong understanding of CI/CD pipelines, code coverage, and deployment workflows
• Excellent technical communication skills and ability to explain and defend technical decisions
• High ownership mindset and strong sense of accountability

Nice‑to‑Have

• Experience working with MongoDB
• Familiarity with JavaScript, React, Node.js, and/or TypeScript
• Experience with Docker and/or Kubernetes
• Experience working on high‑availability or mission‑critical systems

Benefits

• Fixed shifts: 12:00 PM – 9:30 PM IST (Summer) | 1:00 PM – 10:30 PM IST (Winter)
