Working closely with product, operations, and engineering teams, you will translate business requirements into production-ready technical solutions in a fast-paced environment.

Key Responsibilities

• Design, develop, and maintain scalable integrations between internal and external systems using RESTful APIs and webhooks.
• Build full stack applications (backend + frontend) to support integration requirements with high quality and minimal team dependencies.
• Implement CI/CD pipelines and contribute to deployment automation using Docker and containerization.
• Ensure integrations meet security standards and performance benchmarks for production environments.
• Collaborate with product, operations, and engineering teams to translate business needs into technical solutions.
• Mentor on best practices through code reviews and drive standards for integration and full stack development.
