About the Role

• We’re looking for a Security Engineer to build the security foundation for Juicebox from first principles.
• You’ll work directly on the systems that secure our infrastructure, data, and products; designing secure-by-default primitives that scale with the company without slowing engineering down.
• You’ll operate across identity, cloud infrastructure, application security, observability, and internal platform systems.
• The ideal person has strong security instincts, a bias toward automation, and engineering experience.

You may be a fit if

• You're passionate about LLMs and securing agentic systems
• You have strong opinions about building systems that are both secure and developer-friendly.
• You have battle-tested infrastructure or platform engineering instincts.
• You think like an attacker and surface security vulnerabilities before they happen

• You’re comfortable working without heavy PM overhead; you will take ownership in solving the underlying business goal

Sample projects include

• Develop sandboxing and secure execution patterns for AI-powered workflows and agents.
• Implement secure-by-default infrastructure guardrails across AWS using Terraform and GitOps workflows.
• Build automated systems that reduce operational risk.
• Create paved-road security tooling that helps engineers ship securely by default.
• Build a unified identity and access system across internal tooling, infrastructure, and production systems.
• Design secrets management and credential rotation systems with strong auditing and least-privilege guarantees.
• Improve application security around authentication, authorization, API protection, and multi-tenant isolation.
• Build security observability pipelines for logging, detection, and incident response.

What we’re looking for

• Strong background in application security, infrastructure, DevOps, or platform engineering.
• Experience designing and shipping production systems end-to-end.
• Hands-on experience with AWS infrastructure and security primitives (IAM, networking, RDS, etc.).
• Experience with infrastructure-as-code tools like Terraform.
• Familiarity with identity systems such as SSO, IAM, or IdPs.
• Strong communication skills and the ability to drive projects independently.

Bonus Points If You…

• Interest in AI/LLM security, prompt injection, data poisoning, model extraction, etc. and mitigations.
• Experience with tools like Wiz, Doppler, or 1Password.
• Experience with SIEM or security event pipelines.
• Kubernetes or service mesh security experience.
• Experience with sandboxing or secure execution environments.

Why this role

• Build foundational security systems at one of the fastest-growing AI SaaS companies worldwide.
• Shape systems that will support the next decade of company growth.
• Work on hard technical problems with real ownership and impact.
• Join a small team that values speed, autonomy, and strong engineering taste.
