About the role

Mirendil

Mirendil is a tech-first company focused on solving core bottlenecks that unlock step-change acceleration across science and technology. Our first goal is to democratize frontier AI R&D across scientific disciplines. We are building a frontier AI research company and training our own models end-to-end.

The Role

We are looking for a Security Engineer. You'll work across cloud infrastructure, ML systems, and product surfaces to ensure privacy and security measures. Some example areas you might work on (not limited to):

  • Design and implement measures to protect against external threats
  • Design and implement protective measures around data transfer, external attacks, secret management, identity verification
  • Architect systems that protect sensitive assets including model weights, customer data, and training datasets
  • Build secure sandboxed execution environments for AI-generated code and agentic workflows
  • Develop frameworks for safely handling AI agent interactions with external systems and tools
  • Investigate across the stack to respond to security incidents
  • Conduct security design reviews for engineering teams, and implement/maintain security related features for a fast moving product

If you're excited about solving security problems at the frontier of AI - where the threat surface is novel and the stakes are high - we'd love to hear from you.

We offer a base salary of $300,000–$400,000 USD and a meaningful equity grant, depending on experience and background, along with competitive benefits.
