Security Engineer - Member of Technical Staff
About The Position
Simile is seeking a Security Engineer who thrives on securing novel AI products. This role involves owning the security roadmap to ensure the platform is resilient, compliant, and stays ahead of evolving threats. The Security team acts as the guardian of the simulation's integrity, focusing on uncompromising privacy and world-class defenses at the intersection of application security, AI safety, and enterprise-grade privacy to protect foundation models and sensitive data. The team's work is organized into three core pillars: Application Security (shifting left, threat models, secure design reviews), Product and AI/ML Security (defending generative agents against prompt injection, data poisoning, model extraction), and Infrastructure & Compliance (hardening multi-cloud environments, automating identity management for SOC2 and HIPAA standards).
Requirements
- 5+ years of experience in application or infrastructure security within a high-growth environment.
- Deep expertise in securing AWS environments; experience with GCP or Azure is a major plus.
- Ability to think like an attacker to anticipate risks, paired with a collaborative spirit to help engineers remediate them.
- Experience with modern observability and a "you build it, you run it" mentality toward security infrastructure.
- Experience integrating agentic AI workflows into the developer lifecycle to provide real-time security feedback, enabling engineers to be "secure-by-design" as code is written rather than after the fact.
Nice To Haves
- Experience securing AI/ML workloads, specifically defending against prompt injection or protecting model weights.
- Strong K8s (EKS/GKE) experience, specifically around multi-tenant security and resource isolation.
- Proven track record of navigating SOC2, HIPAA, or similar regulatory frameworks in a cloud-native environment.
Responsibilities
- Partner with our largest enterprise customers to navigate the procurement process, leading technical discussions regarding security agreements, providing comprehensive posture overviews, and ensuring alignment on rigorous data handling requirements
- Conduct threat modeling and secure design reviews for new features, ensuring security is a core consideration from initial design through implementation.
- Develop tooling and "paved paths" that allow our engineering and research teams to ship code safely without sacrificing velocity.
- Oversee our bug bounty program and internal vulnerability scanning, prioritizing fixes based on actual risk to our foundation models.
- Build specific defenses against AI-novel risks, including protecting high-throughput inference systems and GPU-accelerated computing environments.
- Manage security configurations via Terraform/Pulumi, ensuring "security-as-code" is the truth across all multi-region environments.
Benefits
- Competitive compensation packages that include base salary, equity, and comprehensive benefits.
- Equity grants are available for eligible roles, subject to board approval.
- Comprehensive medical, dental, and vision coverage.
- Flexible time off policies to support work-life balance.
