- Must have deep contributor-level expertise in Python 3.x. Should have implemented TCP socket-based modules (e.g., for order entry or FIX engine integration), worked with multithreading (e.g., threading, asyncio), and written production-grade code.

- Should have delivered end-to-end RESTful APIs using FastAPI, including request validation, routing, and async support. Familiarity with FastAPIs dependency injection and OpenAPI documentation is expected.

- Must have hands-on experience deploying services to at least one public cloud (e.g., App Engine, ECS, AKS). Should understand service accounts, IAM, monitoring logs, and basic infra scripting. GKE (Google Kubernetes Engine) preferred .

- Must have built and deployed multi-container apps. Should know Dockerfile optimization, layered image strategies, and secure secrets handling.

- Should have written and deployed Helm charts, understood templating logic, values.yaml structure, and release management best practices.

- Must have knowledge with Kafka as producer/consumer, understood offset handling, basic topic configuration, and consumer group patterns. Not required to manage Kafka clusters.

- Exposure to parsing and sending messages via FIX/FIXP using TCP/IP or similar protocols. Understanding of tag-value encoding and session management expected.

- Comfortable with CLI commands, file permissions, log reading (journalctl, dmesg), shell scripting (bash/python).
