Python Infrastructure Engineer - Backend Platform

About the Role:

We are looking for an experienced Python Infrastructure Engineer / Backend Platform Engineer to design, develop, and enhance a new Device Boot Service. The service will manage server/device boot and provisioning requests through REST APIs, persist request and device data in a database, execute long-running boot/provisioning operations using asynchronous workers, and track each request through a state-machine-based workflow. The successful candidate will work closely with engineering and infrastructure teams to finalize the data model, API architecture, state-machine design, and migration strategy, and will be responsible for implementing reliable, scalable, and production-ready service components. The role requires strong backend engineering skills combined with an understanding of infrastructure, server provisioning, device management, and automation technologies.

Key Responsibilities:

• Design and develop production-grade backend services using Python.

• Design and implement RESTful APIs for device/server boot and provisioning workflows.

• Contribute to the design and finalization of:

• Data models and database schemas

• API contracts and endpoint design

• State-machine workflows and state transitions

• Database migration strategy

• Background processing architecture

• Develop API endpoints, request/response models, serialization, validation, and error handling.

• Implement database models and migrations using appropriate Python ORM frameworks.

• Develop asynchronous/background processing using technologies such as Celery, RQ, Dramatiq, or equivalent.

• Implement reliable long-running workflows with:

• Retry mechanisms

• Idempotent task execution

• Scheduled jobs

• Failure handling and recovery

• Concurrency-safe operations

• Design and implement state-machine-based workflows to track boot/provisioning request lifecycle.

• Integrate the service with internal boot, provisioning, BMC, and infrastructure management systems.

• Ensure safe and consistent state transitions in concurrent and distributed environments.

• Write comprehensive unit, integration, and API tests using pytest or equivalent frameworks.

• Implement application observability through:

• Structured logging

• Application and business metrics

• Prometheus

• Grafana

• Health/readiness checks

• Alerting and monitoring

• Troubleshoot production issues and improve system reliability, performance, and scalability.

• Participate in code reviews, architecture discussions, and technical design sessions.

• Prepare and maintain runbooks, technical documentation, API documentation, and operational procedures.

• Collaborate with DevOps, infrastructure, QA, and platform engineering teams to deliver production-ready solutions.

Required Technical Skills :Python & Backend Development :

• 5 to 15 years of overall software development experience, with strong hands-on experience in production Python backend development.

• Strong proficiency in Python 3.x and object-oriented/programming fundamentals.

• Hands-on experience building production-grade backend services.
