WHAT YOU'LL DO:

The Security Foundations organization at CoreWeave keeps CoreWeave Cloud secure

by design, from data centers and GPU fleets to the platform layers powering our

customers' AI workloads. The PKI & Secrets team owns the cryptographic

infrastructure underpinning the confidentiality, integrity, and authenticity of

CoreWeave's data and systems: PKI, secrets management, HSMs, key management, and

code signing.

We partner with teams across the company to deliver cryptographic services that

are secure, reliable, and easy to use at scale.

ABOUT THE ROLE:

As a Senior Security Engineer on the PKI & Secrets team, you will shape how

CoreWeave manages cryptographic infrastructure across its global fleet. You'll

design and operate PKI hierarchies, secrets management platforms, HSM

infrastructure, and key management systems; working hands-on with engineering

teams to integrate these capabilities into their services and workflows.

IN THIS ROLE, YOU WILL:

* Contribute to the design, implementation, and operation of CoreWeave's PKI

infrastructure, including CA hierarchies, issuance policies, certificate

lifecycle management, and trust distribution across Kubernetes clusters and

bare-metal hosts.

* Manage and evolve secrets management platforms, including access policies,

secret lifecycle governance, and integration patterns using External Secrets

Operator and cert-manager.

* Operate and scale HSM infrastructure, including PKCS#11 integration, key

ceremony procedures, and high-availability designs backing our certificate

authorities and signing services.

* Contribute to the design of key management and data encryption solutions for

internal and customer-facing use cases, including envelope encryption and KMS

API design.

* Deliver PKI-based solutions supporting workload identity, mutual TLS, and

hardware attestation.

* Maintain and extend code signing infrastructure for firmware images, UEFI

binaries, container images, and application binaries.

* Develop and enforce cryptographic best practices and policies, and contribute

to post-quantum cryptography readiness.

WHO YOU ARE:

* (5)+ years of experience in security engineering or infrastructure

engineering.

* Strong understanding of PKI concepts including CA hierarchies, certificate

profiles, issuance policies, revocation, and trust distribution.

* Hands-on experience operating HashiCorp Vault or similar secrets management

platforms in production.

* Experience with hardware security modules (HSMs), PKCS#11 interfaces, and key

ceremony procedures.

* Solid understanding of applied cryptography: symmetric and asymmetric

algorithms, digital signatures, envelope encryption, and TLS.

* Proficiency in Go, Python, or similar languages, with the ability to build

production tooling and automation.

* Experience with Kubernetes, including cert-manager, trust-manager, or

External Secrets Operator.

* Demonstrated ability to drive cross-functional initiatives across

infrastructure, platform, and product teams.

PREFERRED

* Experience operating PKI backed by HSMs in a cloud provider or hyperscaler

environment.

* Familiarity with code signing workflows (Authenticode, Cosign/Sigstore,

transparency logs, timestamping).

* Experience with KMS design, including customer-managed keys and multi-tenant

key isolation.

* Understanding of hardware attestation and workload identity (TPM, SPDM,

SPIFFE/SPIRE).

* Exposure to post-quantum cryptography standards and migration planning.

WONDERING IF YOU'RE A GOOD FIT?

We believe in investing in our people, and value candidates who can bring their

own diversified experiences to our teams, even if you aren't a 100% skill or

experience match. If some of this describes you, we'd love to talk.

* You think deeply about how trust is established in complex distributed

systems — and you enjoy making that infrastructure invisible to the teams

that depend on it.

* You're comfortable operating at multiple levels of abstraction, from HSM key

ceremonies to Kubernetes operator design and developer experience.

* You're a pragmatic builder who ships durable solutions in fast-moving

environments.
