Security Engineer

Hark • San Jose, CA

66d • $150,000 - $300,000

About The Position

We're hiring a Member of Technical Staff (Security Engineer) to own security engineering at Hark. You'll threat-model our systems, harden our cloud and product infrastructure, build detection capabilities, and lead incident response when things go wrong. As AI agents become a core part of our product, you'll also be on the frontier of LLM and agent security — a space with very few established playbooks. This role is hands-on; you'll be building and operating, not managing or auditing.

Requirements

• 4–8 years of hands-on security engineering experience.
• Deep fluency in cloud security (AWS/GCP, IAM, Kubernetes, network hardening).
• Experience with detection engineering and incident response — you've triaged real alerts and contained real incidents.
• Ability to read and review infrastructure-as-code (Pulumi, Terraform, or similar) for security issues.
• Genuine curiosity about LLM and agent security — this is new territory and we want someone excited to figure it out.

Nice To Haves

• Experience at a cloud security company (Wiz, Orca, Datadog, Snyk) or a security-forward startup (Stripe, Figma, Ramp, Netflix).
• Familiarity with zero-trust networking (Tailscale, Cloudflare, HashiCorp Vault).
• Prior exposure to AI/agent security threat modeling.

Responsibilities

• Threat-model Hark's infrastructure, product, and agent/LLM attack surfaces.
• Harden cloud infrastructure (EKS, IAM, network access paths) and review IaC for misconfigurations and vulnerabilities.
• Build and maintain detection and alerting pipelines; lead triage and containment during incidents.
• Partner with engineering to embed security into the development lifecycle.
• Define and evolve Hark's security posture as the product and team scale.

Benefits

• The US base salary range for this full-time position is between $150,000 - $300,000 annually.
• The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience.
