Chainguard - Staff Software Engineer, Chainguard Harness
Requirements
• 10+ years of experience in software development • A track record of building and operating production services where security and data confidentiality were hard requirements, not afterthoughts • Experience designing systems that hold confidential customer data end to end • Experience shipping software into air-gapped, disconnected, or highly restricted environments • Deep experience with cloud infrastructure on GCP and/or AWS, including IAM, KMS, networking, and infrastructure as code (Terraform) • Hands-on experience with virtualization and workload isolation, such as KVM, QEMU, Firecracker or Cloud Hypervisor, gVisor, nested virtualization, or bare-metal hosts • A working knowledge of applied cryptography: envelope encryption, key management and rotation, HSM/KMS-backed keys, and signing • Proficiency with Go • Experience with AI tooling and a genuine enthusiasm for applying it to hard problems; experience building agentic systems is a plus • Strong communication skills and proficiency in English. You can explain a security model to an engineer, a security reviewer, and a customer's CISO, and you work autonomously, take initiative, and ask for help early. • A background in offensive security, vulnerability research, penetration testing, or application security, and a sense of what separates a real, exploitable finding from noise • Experience building and running arbitrary third-party code across many languages and build systems • Familiarity with vulnerability data and disclosure: CVE and OSV formats, triage and deduplication, and coordinated disclosure • Experience distributing self-hosted software: Kubernetes and Helm, signed artifacts, SBOMs, and supply-chain provenance • Experience with GitHub or GitLab app integrations • Experience evaluating LLM output quality and managing model cost at scale
Responsibilities
• Own major parts of the system end to end, from design through implementation, rollout, and operation • Build security into the foundation: protecting customer code end to end, least-privilege access, and auditing everything the system and its operators do. Partner with Product and Security on threat models and reviews. • Make Harness a reliable, observable, production-grade service, making sound long-term tradeoffs around scale, cost, technical debt, and build versus buy. • Work directly with customers, Product, and our field team. You'll join customer calls and turn feedback into the roadmap. • Raise the bar for the team through design docs, code review, and mentoring, and by showing how AI tooling can make a small team move fast without cutting corners on security.
