Senior IT Infrastructure & Systems Engineering - AWS

Overview

Senior Systems Engineer (AWS) on the IT Infrastructure & Systems Engineering team, owning the design, automation, and reliability of cloud and identity infrastructure across AWS and GCP, with hybrid identity spanning Okta, Active Directory, and Entra ID. This role covers infrastructure and identity only and does not include SaaS application administration or endpoint management.

What you'll do

• Design and operate AWS infrastructure: multi-account and multi-region structure, VPC and network design, IAM, compute, and storage, with security and cost in mind
• Plan and test high availability and disaster recovery, and run regular cost reviews
• Support GCP workloads, org-level IAM, and org policy
• Maintain consistent networking, connectivity, and guardrails across clouds and on-prem
• Own Terraform module design, remote state, and CI/CD-driven plan/apply with drift detection
• Use Ansible or equivalent for configuration management of Linux systems
• Automate operational and lifecycle work with Python, PowerShell, or Bash, vendor APIs, and workflow platforms (Okta Workflows, n8n, or similar), and track the toil removed
• Own Okta (Identity Engine) architecture: SSO (SAML/OIDC), SCIM lifecycle provisioning, MFA, authentication policy, and Device Trust
• Manage hybrid identity across Active Directory and Entra ID, including sync and federation
• Own service-account and machine-identity lifecycle, secrets management, and least-privilege role design across cloud and identity platforms
• Define SLIs and SLOs with service owners, and build the metrics, logs, traces, dashboards, and alerting that support them with low noise
• Work with paging and ITSM tooling (e.g., PagerDuty or Freshservice) and OpenTelemetry-based instrumentation
• Join the on-call rotation, lead major incidents, write RCAs, and drive fixes that prevent repeat pages
• Troubleshoot across network, OS, identity, and application layers
• Drive vulnerability remediation and hardening
• Own audit evidence collection and remediation for SOC 2 or similar
• Review and document risk exceptions
• Review designs and pull requests, mentor engineers, and maintain runbooks and architecture documentation
• Partner with security, DevOps, and application teams on infrastructure changes

What you'll need

• 6+ years in systems, infrastructure, or cloud engineering
• Production AWS architecture experience beyond basic provisioning, including multi-account design and DR
• Hands-on GCP experience (IAM, projects, org policy, networking)
• Terraform at scale: module design, state management, testing, and pipeline integration
• Production Okta experience: debugging SAML/OIDC failures, building SCIM integrations, and working with the Okta API
• Working knowledge of Active Directory and Entra ID in a hybrid environment, including LDAP
• Understanding of modern authentication standards (OAuth 2.0, FIDO2)
• Strong networking fundamentals (TCP/IP, DNS, VPN, load balancing, firewalls)
• Linux administration
• Proficiency in Python or PowerShell, plus Bash
• Experience with an observability stack (Datadog, Prometheus/Grafana, CloudWatch, ELK, or similar) and with defining SLOs
• Willingness to join an on-call rotation and lead incidents

Nice to have

• Okta Certified Professional or Administrator
• AWS Solutions Architect Professional, AWS Security Specialty, or equivalent
• GCP
• Okta Workflows, n8n, or other automation platform experience
• Zero trust or device-trust implementation experience
• Kubernetes (EKS) and CI/CD (GitHub Actions, Jenkins)
• Experience supporting SOC 2 or similar audits
• Windows Server

Details

• Location: Bengaluru, India; hybrid
• On-call: primary/secondary rotation, roughly one week in 4, including weekends; pages tied to defined severity levels
• Expect some out-of-hours coverage to support global operations
