FwK29HC AbQ65FEF – AI Security Platform

Location: SF Bay Area (hybrid, 2–3 days a week on-site)

Employment type: Full-time, direct hire

About the company

Our client is a venture-backed AI security startup that recently raised a new funding round from top-tier security investors. Its founders came from a leading AI-native security company. The platform helps enterprises adopt AI tools like Microsoft Copilot and AI agents safely, by finding and fixing what those tools can access that they shouldn’t. Every security team is dealing with this problem right now, and this company is building one of the main products for it.

The role

You’ll be a core backend engineer on a small team, working directly with the founders. You’ll design, build, and scale the services behind the product, and you’ll own features from design through production as the platform grows with enterprise customers.

What you’ll do

• Design and build scalable backend services and APIs in TypeScript (NestJS) and Python

• Build integrations with Microsoft Azure and Microsoft 365 to analyze permissions, data exposure, and AI access risk

• Design data models and optimize performance in PostgreSQL

• Build services that process large amounts of enterprise data reliably and securely

• Work with the founders, product team, and customers to turn security problems into product features

• Help set engineering standards, architecture decisions, and best practices as the team grows

What we’re looking for

• Strong hands-on experience as a backend software engineer building production systems

• Real, hands-on Azure experience (required)

• Proficiency in TypeScript/Node.js and/or Python

• Solid experience with relational databases, ideally PostgreSQL

• Startup experience: you’re comfortable with ambiguity and with owning your work end to end

• A builder’s mindset: you like shipping product, not just maintaining systems

Nice to have

• Experience with Microsoft Entra ID, Microsoft 365, SharePoint, or Microsoft Graph APIs

• Background in identity, access management, or data security

• Exposure to AI or LLM-driven products

• Experience building enterprise B2B SaaS

Why join

• Get in early at a well-funded company in the fastest-growing area of cybersecurity

• Work directly with experienced founders and have real influence on product and architecture

• Competitive base salary plus meaningful equity

• Solve a problem that every enterprise security team is dealing with right now
