Senior DevOps Engineer — AWS Infrastructure & Platform Operations

FenixCommerce | Noida, India (Remote / Hybrid) | Full-time

——

We power the delivery promises on pdp, cart, and checkout pages for brands like VUORI, Steve Madden, Negative, and KUIU. Hundreds of millions of API requests per year.

We're hiring the person who takes over our already reliable and robust platform infrastructure to next level - making it foolproof, cheaper and faster to run and operate

——

THE ROLE

You're not joining a DevOps team. You ARE the DevOps function. Every infrastructure decision — architecture, tooling, vendor, cost trade-off — is yours to own.

Three outcomes define success:

→ Zero manual ops. Auto-scaling, self-healing, anomaly-based alerting. No more 2am firefighting on ELK connection storms or thread pool exhaustion.

→ 80%+ infrastructure cost reduction.

→ Infra to support Sub-15ms P99 API latency.

——

WHAT YOU'LL WORK WITH

The stack:

• ECS production tasks across multiple clusters

• Elasticsearch clusters, Thousands of indices (active ES 7.9 → Elastic 8 migration)

• Java microservices: Java 11/17, Spring Boot 2.x/3.x, WebFlux

• Maven → Docker → ECR → ECS deployment pipeline

• AWS MSK (Kafka), Glue/Athena/S3 data lake, CloudFront CDN

• Terraform (expanding coverage), Route 53, ALB, WAF, IAM

• ECS Fargate (zero capacity planning)

• DynamoDB for key-value order lookups

• SQS FIFO + Lambda for async bulk writes

• ElastiCache Redis + Caffeine L1 for multi-tier caching

• CloudFront edge caching for PDP responses

• CloudWatch anomaly detection replacing manual monitoring

——

WHAT WE NEED

Must have:

• 5+ years in DevOps/SRE/Cloud Infrastructure with deep AWS experience

• Production ECS management (EC2 and/or Fargate) at scale

• Hands-on Elasticsearch/OpenSearch admin — cluster ops, index lifecycle, migrations

• Java/Spring Boot CI/CD pipelines (Maven, Docker, ECR)

• AWS networking: VPC, ALB, Route 53, IAM, security groups

• Terraform or CloudFormation

• A track record of eliminating operational toil through automation

Nice to have:

• Serverless architecture: Lambda, Fargate, SQS, DynamoDB, EventBridge

• Kafka/MSK administration

• AWS Glue, Athena, S3 data pipelines

• Python deployment (FastAPI, ML model serving, ONNX)

• Ecommerce or SaaS platform ops experience

——

WHAT SUCCESS LOOKS LIKE

30 days: You understand the full architecture. Observability layer is deployed on ES clusters.

——

WHY THIS ROLE

• Ownership — you're not one of 50 DevOps engineers. You're THE infrastructure owner.

• Impact — your work directly enables enterprise deals worth millions in ARR.

• Greenfield — we're actively rearchitecting from legacy to serverless. You're building it, not maintaining someone else's decisions.

• Scale — hundreds of millions of requests, multi-carrier optimization, real-time delivery promises. These are engineering problems, not configuration tasks.
