Maze is partnering with a stealth-mode startup that's rebuilding core banking from the ground up. They’re creating the world’s first open-source, AI-native "Thin Ledger"—set to replace legacy infrastructure at Tier 1 banks.

We're looking for a Founding Platform Engineer to drive the infrastructure behind mission-critical systems: think active-active, five-nines uptime, and real-time observability at a global scale.

What You'll Do:

• Lead our AI-powered SRE approach: observability, remediation, and auto-response
• Enforce zero-trust, multi-tenant security and compliance (SOC2, ISO 27001)
• Define IaC foundations (Terraform, GitOps, Helm)

What We're Looking For:

• Expertise with Kubernetes and Distributed Systems
• Experience building production infrastructure at scale (multi-region, high-availability)
• Extensive experience building both on-premises & cloud infrastructure at scale from scratch
• AI-curious or AI-native: excited to build agent-powered operations
• Passion for open-source, clean architecture
• Software development experience (Bonus points for Go/Golang)
• Bonus: background in financial systems, core banking, or regulated infrastructure
• Strong ownership: build core infrastructure from scratch
• Ability to work with a high-caliber team, fast-paced environment, and product-minded founders with experience in top tech companies
• Help define an open-source platform from day one
• Clear path to tech unicorn status with fruitful equity included
