You will play a key role in building, maintaining, and scaling a core backend API platform. This is a highly hands‑on leadership role, where you will spend most of your time writing production code while guiding technical decisions and setting backend engineering standards. You will own the backend lifecycle, ensuring systems are robust, secure, and designed to scale.

• Lead by example through hands‑on development of robust, scalable, and secure RESTful and event‑driven APIs using FastAPI and OpenAPI 3.0+.
• Own backend architecture and technical execution, serving as a primary contributor to the codebase.
• Establish and enforce best practices for API design, versioning, documentation, and maintainability.
• Design and build modular, extensible backend systems integrating multiple services, databases, and third‑party clients.
• Develop high‑performance, low‑latency APIs using async/await patterns, FastAPI, Pydantic, and SQL Alchemy.
• Build reusable microservices, internal libraries, and backend components to support a distributed architecture.
• Engineer for scale using asynchronous processing and task queues (Celery, Rabbit
  
  MQ, Kafka).
• Design and implement integrations with relational (Postgre
  
  SQL) and No
  
  SQL (Redis) data stores.
• Build cloud‑native backend services leveraging containerization (Docker) and orchestration (Kubernetes).
• Implement authentication, authorization, and security best practices (OAuth2, JWT), ensuring compliance with industry standards.
• Collaborate closely with product managers, frontend engineers, and QA teams to deliver high‑impact features.
• Mentor backend engineers through code reviews, technical guidance, and best‑practice enforcement.
• Own the full backend lifecycle from design and development through deployment, monitoring, and optimization.

• 8+ years of hands‑on backend engineering experience with Python, focused on API and service development.
• Expert‑level experience with FastAPI, OpenAPI/Swagger, Pydantic, and SQL Alchemy.
• Strong mastery of asynchronous programming in Python (asyncio).
• Deep understanding of RESTful API design, versioning strategies, and API documentation.
• Solid experience with Postgre
  
  SQL, Redis, and modern ORM patterns.
• Proven experience building and running containerized services using Docker.
• Practical experience with Kubernetes concepts and cloud platforms (AWS preferred).
• Strong understanding of CI/CD pipelines, infrastructure‑as‑code, and observability tooling.
• Hands‑on experience implementing API security standards (OAuth2, JWT) and mitigating common vulnerabilities.
• Strong commitment to code quality, testing, and peer review.
• Demonstrated technical leadership through mentorship, code reviews, and collaborative problem‑solving.
• Excellent communication skills and ability to clearly explain technical decisions.
