Job Summary:

We are seeking an experienced Backend Engineer to build and operate AI products across AWS/Azure/GCP using Python Flask and containerized services on ECS. Your mandate: make things work endtoend, quickly—from API to DB to network—prioritizing throughput and latency in practice over ceremony.

Key Responsibilities (debuggingfirst, e2e outcomes):

· Own e2e flows: API auth service queue/cache DB network deployment; deliver working software fast.

· Debug quickly: isolate problems across app, DB, infra, and network layers; produce clear RCAs and durable fixes.

· Spinup speed (TTFD): bootstrap a new Flask on ECS service with CI/CD, secrets, logs, metrics, health checks, and runbook within 1 business day.

· Golden signals & SRE hygiene: define and track MTTD 15 min, MTTR 2 hrs (Sev2), alert routing, and error budgets; prevent regression with tests and deployment guards.

· Networking you can trust: VPC/subnets/NACLs/SGs, ALB/NLB listeners/target groups/health checks, Route 53/DNS, TLS/mTLS, NAT/VPC endpoints/PrivateLink, ECS awsvpc port mappings.

· Performance in practice: reduce tail latency (p95/p99), eliminate headofline blocking; tune queries, caching, connection pools, and gunicorn worker models.

· Observability for debugging: highsignal logs, correlation IDs, metrics, and traces to cut MTTR; dashboards and actionable alerts.

· Ship & operate: IaC (Pulumi/Terraform), CI/CD (AWS CodePipeline or equivalents), safe rollouts/rollbacks; oncall with runbooks and postmortems.

Required Skills & Experience:

· Bachelor’s degree in CS/SE or related field; 6 years as a Backend Engineer.

· Cloud: build on AWS or Azure; containers on ECS (Fargate or EC2).

· IaC: Pulumi/Terraform (2 yrs); CI/CD with AWS CodePipeline or equivalents.

· Python + Flask: blueprints, dependency injection, config management; WSGI and gunicorn worker tuning; can stand up a minimal service in hours.

· Debugging expert: `pdb/ipdb`, `py-spy`, `cProfile`, `tracemalloc`, flamegraphs; log/trace correlation; binary search through systems; proven MTTR 2 hrs for Sev2 class incidents.

· Networking expert: VPC/subnets/route tables/NACLs/SGs, ALB/NLB, TLS/mTLS, Route 53, NAT, VPC endpoints/PrivateLink; ECS service discovery and port mapping; can explain 502/504 causes and fixes.

· Auth & security: Auth0/Cognito

· OAuth2/OIDC, secret mgmt, leastprivilege IAM.

· Data: SQL (Postgres/MySQL) one NoSQL; schema design, indexing, query tuning, connection pooling.

· Proven experience building production products with ECS Flask Python; collaborates well with FE/ML/Data.

· Experience with multithreading through celery, multiprocessing, and equivalent.

· 2+ years of experience in Serverful & Serverless.

· 2+ years building complex ECS tasks on AWS.

· Follows TDD & BDD best practices for development

Preferred Qualifications:

· Security experience (threat modeling, IAM reviews, remediation).

· Strong AWS knowledge; certification (e.g., SAA) is a plus.

· Packetlevel debugging or SRE background; React experience is a plus (not required).
