Build the future of enterprise knowledge intelligence. Lead a world-class team. Ship bulletproof APIs.

The Mission

We’re building the definitive enterprise knowledge platform—a state-of-the-art API ecosystem that transforms how organizations aggregate, synthesize, and operationalize their collective knowledge intelligence. As Principal Architect, you’ll engineer the foundation that enables developers to rapidly build compliant, sophisticated agentic experiences powered by trusted answers.

What You’ll Own

• Platform Architecture: Design and build a fail-safe SaaS platform that handles enterprise-scale knowledge aggregation and synthesis with zero compromise on reliability
• Team Leadership: Recruit, build, and lead a small team of world-class engineers who share your obsession with architectural excellence
• API Excellence: Create developer-friendly APIs that make complex knowledge synthesis and consumption feel effortless while maintaining enterprise compliance and security standards

Technical Vision: Drive architectural decisions that balance cutting-edge innovation with production stability and scalability

The Challenge

This isn’t just another API platform. You’re building the nervous system for enterprise knowledge—where milliseconds matter, compliance is non-negotiable, and failure isn’t an option. Your platform will power mission-critical agentic applications that organizations depend on for their most important decisions.

What We’re Looking For

• Proven architect with 10+ years building enterprise-scale platforms, with at least five at a cloud startup
• Team builder who attracts A-players and creates environments where they do their best work
• API craftsperson with deep experience designing developer experiences that feel magical

Enterprise mindset with hands-on experience in compliance, security, and fail-safe system design

Technology polyglot comfortable with modern cloud-native architectures, microservices, and emerging AI/ML infrastructure

Why This Role Matters

Every API call your platform handles could be powering a decision that affects thousands of employees, millions in revenue, or critical business outcomes. You’re not just building software—you’re building the trusted knowledge infrastructure that makes AI enterprises smarter, faster, and more capable.
