SDE3, Infrastructure Security Engineer (DevSecOps)
BengaluruFull-timePosted today
About the role
Infrastructure security-focused SDE3 role responsible for defining and enforcing security baselines across Kubernetes, cloud accounts, CI/CD, and supply chain; build automation and AI-assisted security workflows; partner with compliance; on-call and incident leadership.
Responsibilities
- Define and enforce security baselines for Kubernetes, cloud accounts, container images and CI/CD across all clouds
- Write the policy gates in the delivery pipeline (OPA / Conftest, Kyverno or equivalent): network exposure, IAM, image provenance, secrets, data residency
- Own secrets and workload identity: Vault or cloud-native equivalents, rotation, short-lived and scoped credentials, no long-lived keys
- Build detection and response: runtime security (Falco / Tetragon or equivalent), log-based detections, alerting and playbooks
- Run the finding-to-fix loop for security findings: triage, assign, fix, add a detection, retest
- Use LLMs and AI agents in security work: triaging findings, reviewing infrastructure changes, tuning detections, drafting incident timelines — and secure the agents themselves with scoped, short-lived permissions and audit trails
- Harden the supply chain: image signing and scanning, dependency policy, SBOMs
- Automate compliance evidence (CERT-In, ISO 27001, SOC 2, DPDP) together with the compliance team
- Set the security standards other engineers follow and review security-relevant changes
- Take part in on-call and lead security incidents
Qualifications
- 5–9 years in DevOps, platform or security engineering, with at least 2 in a bank, fintech, payments company or other regulated environment
- Strong Kubernetes and Linux fundamentals; has run production clusters on at least one major cloud
- Hands-on with Terraform / OpenTofu and GitOps (ArgoCD or Flux)
- Has built security automation, not only operated tools: policy-as-code, secrets rotation, CI/CD security gates or detection pipelines
- Working knowledge of IAM, network security, TLS and secrets management across clouds
- Scripting and tooling in Python or Go
- Has been through security audits and knows what evidence auditors need
- Has built or used AI-based automation in infrastructure or security work, and understands the risks of AI agents: prompt injection, over-broad permissions, unreviewed actions
- Nice to have: Vault, SPIFFE / SPIRE, Falco or Tetragon, Cloudflare WAF, incident response lead experience, multi-cloud experience
