Senior PKI & HSM Engineer

We're looking for a Senior PKI & HSM Engineer to own our cryptographic infrastructure end-to-end. This is a deeply technical role for someone who lives and breathes certificates, keys, and HSMs — and who can bring automation and DevOps sensibilities to modernize how we operate them.

What You'll Do

Manage Public Key Infrastructure across its full lifecycle, including certificate issuance, renewal, revocation, and policy enforcement at enterprise scale
Integrate and maintain Hardware Security Modules (HSMs) for secure cryptographic key storage and operations, ensuring high availability and regulatory compliance
Administer Certificate Lifecycle Management (CLM) platforms to automate provisioning and eliminate expiration-related outages
Enforce secure key management practices around rotation, storage, auditing, and policy compliance
Lead L3-level troubleshooting for PKI, HSM, and CLM issues across cloud, on-prem, and containerized environments
Develop automation using Python, Bash, and RESTful APIs to streamline certificate operations, key rotations, and compliance reporting
Work across AWS, Azure, and GCP, integrating native key management services (KMS, Key Vault, Cloud KMS) with our PKI ecosystem
Partner with application, infrastructure, and security teams to embed cryptographic best practices across the organization

Nice to Have (DevSecOps Exposure)

Beyond the core PKI/HSM work, you'll have opportunities to contribute to our broader security engineering efforts. Familiarity with any of the following is a plus:

Designing secure CI/CD pipelines with Jenkins, GitLab CI, or GitHub Actions
Containerized workloads using Docker and Kubernetes
Security platforms like Trend Micro Vision One and container security tooling
Observability stacks like ELK, monitoring, and incident response workflows
Vulnerability detection and remediation across the SDLC

What We're Looking For

Deep, hands-on experience managing enterprise PKI (issuance, revocation, OCSP/CRL, trust hierarchies)
Strong working knowledge of HSMs (Thales, Entrust, AWS CloudHSM, or similar) and PKCS#11
Experience with Certificate Lifecycle Management platforms (Venafi, AppViewX, Keyfactor, or equivalent)
Solid scripting skills in Python and Bash, plus comfort working with RESTful APIs
Working knowledge of at least one major cloud provider's key management services
L3-level troubleshooting experience across Linux, Windows, and networking
A security-first mindset and a track record of automating manual cryptographic operations

Location: Bangalore

Working Mode: WFO (5 days a week)
