Zeno; Bengaluru; On-site; INR 1,500,000 - 2,500,000; Full time

Job summary

Zeno is building the backend platform powering our EV battery-swapping ecosystem, running on AWS with containerized microservices. We seek a DevOps Engineer to own infrastructure, CI/CD pipelines, and production reliability across staging and production environments.

Design and maintain AWS infrastructure (ECS, RDS, SQS, S3, IAM, CloudWatch, Secrets Manager). Own CI/CD using GitHub Actions and ECR, plus IaC with Terraform/CloudFormation.

Qualifications

• 5+ years in DevOps, SRE, or infrastructure roles.
• Hands-on AWS with ECS, RDS, SQS/SNS, S3, IAM, CloudWatch.
• IaC experience with Terraform or CloudFormation.
• CI/CD and containerization experience (GitHub Actions, Docker, ECS/Kubernetes).
• Scripting in Python, Bash, or Node.js for automation.
• Strong networking fundamentals (VPCs, load balancers, DNS, security groups).
• Monitoring/observability with CloudWatch/Prometheus/Grafana.
• Experience with PostgreSQL and ClickHouse or similar.
• Excellent troubleshooting and incident response skills.
• Strong communication and collaboration.

Responsibilities

• Design, build, and maintain AWS infrastructure for core backend microservices.
• Own and evolve CI/CD pipelines for containerized services to ECS, including ECR management.
• Create and maintain IaC for reproducible environments (Terraform/CloudFormation).
• Administer and scale Envoy Proxy for service communication and traffic management.
• Set up observability: CloudWatch logs, metrics, dashboards, alerting for production.
• Manage Redis for low-latency data serving within the VPC.
• Support ClickHouse cluster ops: data lifecycle, backups, performance tuning.
• Own DLQ monitoring and alerting for SQS-based workflows.
• Enforce security best practices across the VPC: IAM least-privilege, secrets, WAF rules.
• Manage environment promotion (stage → prod) and blue/green or rolling deployments.

Job description

Zeno is building the backend platform that powers our EV battery-swapping ecosystem — covering vehicle telemetry, swap station orchestration, wallet & payment transactions, and fleet partner management, all running on AWS across a set of containerized microservices. We're looking for a DevOps Engineer to own our infrastructure, CI/CD pipelines, and production reliability across staging and production environments.

What you'll do

• Design, build, and maintain AWS infrastructure (ECS, RDS, SQS, SNS, S3, IAM, Secrets Manager, CloudWatch, WAF, Route 53) supporting core backend microservices
• Own and evolve CI/CD pipelines (GitHub Actions) for build, test, and deployment of containerized services to ECS, including ECR image management
• Build and maintain infrastructure-as-code (Terraform/CloudFormation) for reproducible, version-controlled environments
• Administer and scale the Envoy Proxy layer for service-to-service communication and traffic management
• Set up and maintain observability — centralized logging (CloudWatch Logs), metrics, dashboards, and alerting for production services
• Manage and monitor Redis for low-latency live data serving, optimizing placement within the VPC to minimize cross-AZ data transfer costs
• Support ClickHouse cluster operations — data lifecycle policies (materialized views, TTLs), backups, and performance tuning for high-volume telemetry ingestion
• Own dead-letter queue (DLQ) monitoring and alerting for failed or incomplete transaction processing across SQS-based workflows
• Implement and enforce security best practices across the VPC — network segmentation, IAM least-privilege policies, secrets management, and WAF rules
• Manage environment promotion (stage → prod) and support blue/green or rolling deployment strategies with minimal downtime
• Collaborate with backend engineers to troubleshoot production incidents, perform root-cause analysis, and improve system reliability
• Set up and maintain database backup, disaster recovery, and scaling strategies for RDS and ClickHouse

What you bring

• 5+ years of experience in DevOps, SRE, or infrastructure engineering roles
• Strong hands-on experience with AWS services — ECS, RDS, SQS/SNS, S3, IAM, CloudWatch, Secrets Manager, Route 53
• Experience with infrastructure-as-code tools (Terraform, CloudFormation, or similar)
• Proficiency in building and maintaining CI/CD pipelines (GitHub Actions or similar)
• Experience with containerization and orchestration (Docker, ECS/Kubernetes)
• Working knowledge of scripting languages (Python, Bash, or Node.js) for automation
• Understanding of networking fundamentals — VPCs, load balancers, DNS, security groups
• Experience with monitoring/observability tools (CloudWatch, Prometheus, Grafana, or similar)
• Familiarity with relational databases (PostgreSQL) and exposure to time-series/columnar databases (ClickHouse or similar)
• Strong troubleshooting and incident response skills
• Good communication and collaboration skills

Nice to Have

• Experience with service mesh/API gateway technologies (Envoy Proxy)
• Exposure to message queue systems (SQS, SNS, RabbitMQ) and DLQ handling patterns
• Experience with Redis or other in-memory caching systems
• AWS DevOps Engineer Professional or Sys-Ops Administrator certification (or equivalent)
• Experience working in regulated/financial systems requiring auditability
• Exposure to IoT/telemetry-heavy or high-throughput data platforms

What You'll Gain

• Ownership of infrastructure and deployment pipelines for a fast-growing EV mobility platform
• Exposure to a modern microservices architecture spanning telemetry, payments, and fleet management
• Opportunity to shape DevOps/SRE practices from the ground up
• Collaborative environment working closely with backend, frontend, and product teams
