Python Developer

Hiring Python / Backend Engineer, Plano, TX- Fulltime role, NO C2C, Onsite 5 days a week.

This role requires deep expertise in network programming, async Python, and cloud infrastructure to design and operate a latency-sensitive, policy-driven gateway that handles massive concurrent streaming connections at scale.

What we are looking for

• Async Python & Network Programming (3 + yrs) – Strong hands on experience with asyncio, aiohttp/anyio, low level TCP/UDP sockets, WebSocket & SSE servers, TLS handshake, connection pooling, keep alive, and zero copy buffering.

• Streaming & Large Payload Handling – Ability to manage chunked transfer, bidirectional streaming, back pressure and high throughput data paths for real time LLM inference.

• Protocol Knowledge – Working familiarity with HTTP/2 & HTTP/3 (multiplexing, HPACK), gRPC, and occasional custom protocol parsers.

• FastAPI Based Backend (3 + yrs) – Design, develop and test production grade REST/Streaming APIs; pragmatic use of Pydantic, dependency injection and OpenAPI docs.

• Containerization & Kubernetes – Docker, AKS/EKS/GKE deployment experience; HPA/VPA scaling, rolling updates, and service mesh (e.g., Istio/Envoy) basics.

• Async Messaging & Event Driven Design – Production use of Redis Streams, RabbitMQ or Kafka for decoupled task queues, retries and back off logic.

• PostgreSQL & Vault – Advanced query tuning, partitioning, PgBouncer pooling, plus HashiCorp Vault (dynamic secrets, transit encryption) for key management.

• Cloud Networking & Security – L4/L7 load balancing, TLS termination, reverse proxy (NGINX/Envoy), mTLS between services, and automated cert lifecycle (ACME/Let’s Encrypt).

Work experience desired

• Enterprise Security Gateways – Integration with CASB/DLP/WSS or similar edge security platforms; centralized logging & audit trails.

• IAM & SSO – Configuring Azure AD/Entra ID, Okta, SAML 2.0 or OIDC SSO flows; managing Conditional Access & SCIM provisioning.

• AI/LLM Pipelines – Building prompt engineering workflows, PII anonymisation, and monitoring Azure OpenAI (or comparable) usage, rate limits & cost.

• API Gateway Operations – Custom webhook/REST integrations, circuit breaker patterns, rate limiting, auto retry and health checking.

• Observability & FinOps – End to end monitoring with Datadog, Prometheus/Grafana or Azure Monitor; proactive cost optimisation and 24/7 incident response (SLA/SLO).
