• Own system integration across the stack — from embedded firmware and gateways to backend microservices and cloud infrastructure.
• Provide technical leadership and mentorship to software engineers; conduct code reviews and enforce engineering quality standards.
• Drive the development and optimization of CI/CD pipelines; ensure automated testing, deployment, and rollback strategies are robust and reliable.
• Collaborate closely with other engineers on technical roadmaps, architecture decisions, and resource planning.
• Ensure cloud and on-premise infrastructure is scalable, secure, and cost-efficient; oversee monitoring and incident response practices.
• Champion TDD or testing best practices; ensure teams write thorough unit and integration tests.
• Maintain comprehensive technical documentation and encourage good documentation practices across the team.
• Lead maintenance, troubleshooting and performance optimization efforts across existing backend services and databases.

Requirements:

• Strong background in both backend and frontend development.
• Proven experience leading or mentoring engineers in an Agile / Scrum team.
• Expert proficiency in TypeScript/JavaScript and Python.
• Strong experience architecting solutions with NestJS and/or FastAPI, including SQL and NoSQL database design.
• Deep understanding of React and React Native application architecture.
• Experience designing and documenting APIs via Swagger / OpenAPI.
• Solid understanding of communication protocols such as MQTT, HTTP, BLE, or similar.
• Strong knowledge of microservices architecture, distributed systems, and system integration patterns.
• Experience designing CI/CD pipelines, preferably using tools like GitHub Actions, Jenkins, or GitLab CI.
• Hands-on experience deploying and scaling applications on cloud platforms and on-premise.
• Excellent problem-solving, architectural thinking, and debugging skills.
• Strong communication skills and ability to collaborate across departments.
• Passion for building maintainable, high-quality systems and mentoring others to do the same.
