Security Engineer

About the role

Nooks is the Agent Workspace for Sales, where reps and AI agents execute and decide next moves together across 1M+ interactions per day. This role involves owning security reviews and threat modeling for new and existing product surfaces, building and improving core security processes, hardening cloud and application infrastructure, and supporting enterprise customer trust.

Responsibilities

• Own security reviews and threat modeling for new and existing product surfaces.
• Build and improve core security processes (secure SDLC, detection & response).
• Harden our cloud and application infrastructure and drive remediation of high-priority risks.
• Help define how we secure AI agents and govern their use — guardrails, data exposure, prompt-injection and abuse risks.
• Support enterprise customer trust: compliance (SOC 2), and customer-facing security needs.
• Partner closely with product and infra engineering to embed security into how we ship.

Requirements

• 4 - 5+ years of hands-on information security experience.
• Experience at a startup or early-stage company; comfort with ambiguity, autonomy, and high ownership.
• Strong fundamentals in application and/or cloud security (AWS/GCP).
• Pragmatic judgment — able to prioritize risk and do more with less.
• Clear communication and a collaborative, low-ego style.

Qualifications

• Experience securing AI agents / LLM systems or governing AI agent use within an organization.
• Enterprise compliance experience (SOC 2, ISO 27001).

Skills

• Security architecture and design.
• Cloud security (AWS/GCP).
• Application security.
• Threat modeling and risk assessment.
• Secure software development lifecycle (SDLC).
• Incident response and forensics.

Benefits

• Frontier security problems.
• Securing AI agents and how they operate inside organizations is largely unsolved territory — you'll help define how it's done.
• Top-of-market compensation.
• Paid time off.
• Flexible work schedule.
• Professional development opportunities.
• Comprehensive benefits package.

Pay

The target salary range for this role is $200,000 - $315,000. On top of base salary, we also offer equity, generous perks and comprehensive benefits.
