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:

1. Data models and database schemas

2. API contracts and endpoint design

3. State-machine workflows and state transitions

4. Database migration strategy

5. 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:

1. Retry mechanisms

2. Idempotent task execution

3. Scheduled jobs

4. Failure handling and recovery

5. 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:

1. Structured logging

2. Application and business metrics

3. Prometheus

4. Grafana

5. Health/readiness checks

6. 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.
