Senior DevOps/infrastructure engineer (AWS, Terraform)

We are looking for a Senior DevOps / Cloud Infrastructure Engineer to design, build, and operate AWS infrastructure for an agentic research assistant in the Pharma / Life Sciences domain, with planned expansion into other research areas.

This is a hands-on infrastructure ownership role, covering cloud architecture, Kubernetes operations, CI/CD, and production reliability.

We are recruiting on behalf of the client. Full project details will be shared with shortlisted candidates.

Project Scope

• Design, build, and operate AWS infrastructure for a production-grade agentic research assistant
• Own Infrastructure as Code (Terraform) across multiple environments (dev / stage / prod)
• Build and maintain CI/CD pipelines for infrastructure and application deployments
• Ensure reliability, security, observability, and cost control
• Prepare runbooks, support incident response, and improve operational maturity
• Collaborate closely with backend and data teams (Python / Java, APIs, data products)

Responsibilities

• Design and operate scalable, secure, and reliable AWS infrastructure
• Own and evolve Terraform codebase (modules, environments, state)
• Build CI/CD pipelines using GitHub Actions for infra and app deployments
• Operate and support Kubernetes (EKS) clusters in production
• Implement observability, alerting, and operational best practices
• Participate in incident handling, root cause analysis, and postmortems
• Work closely with engineering teams to support deployment and runtime needs

Must-Have Requirements

AWS (Production Experience)

Hands-on experience with:

• EKS: cluster setup and operations, node groups, upgrades, autoscaling, ingress, IAM/OIDC
• ECR: image publishing, lifecycle policies, CI integration
• VPC: subnets, routing, NAT / IGW, security groups, NACLs, endpoints, peering (as needed)
• RDS (PostgreSQL): provisioning, HA, backups & restore, basic tuning, monitoring
• Neptune: operational understanding (networking, access control, backups, monitoring)
• EC2: supporting workloads or legacy components when required
• IAM: least-privilege access models, roles & policies, secure access patterns

Infrastructure as Code (Terraform)

Strong hands-on experience with:

• Terraform module design
• State management and remote backends
• Workspaces / environment separation
• Plan / apply workflows
• Secrets and configuration management patterns
• Change management and safe rollouts

Kubernetes & Packaging

• Strong Kubernetes operations experience
• Helm for packaging and deployments (charts, values management, release lifecycle)

CI/CD

Practical experience with GitHub Actions:

• Build / test / deploy pipelines
• Environment promotion and approvals
• Secrets management
• Infrastructure pipelines (terraform fmt / validate / plan / apply)

Operations & Quality

• Observability fundamentals: logging, metrics, tracing, alerting
• SLO / SLA thinking
• Incident handling, postmortems, and runbooks
• Security best practices: secure networking, secrets handling, access control, auditability

Nice-to-Have (Strong Plus)

• Experience with event-driven or distributed systems
• Familiarity with Python (enough to support infra tooling and collaborate on deployments)
• Experience supporting Java services in containerized / Kubernetes environments
• Strong AWS cost optimization skills (rightsizing, autoscaling, storage lifecycle)

Engagement Details

• Level: Senior
• Domain: Pharma / Life Sciences (research-focused product)
• Work format: Remote
• Recruitment: On behalf of the client (details shared later)
