Principal Platform Engineer | Fintech | London | Up to £200k + Equity | London (Min 4 days per week in office)

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 Principal Platform Engineer to drive the infrastructure behind mission-critical systems: think active-active, five-nines uptime, and real-time observability at global scale.

What You'll Do:

• Own platform architecture for our next-gen ledger infrastructure
• Scale multi-region Kubernetes environments across cloud & on-prem
• Harden distributed systems (Kafka, Redis, CockroachDB) for global banking workloads
• 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:

• Expert with Kubernetes and Distributed Systems
• Experience building production infrastructure at scale (multi-region, high-availability)
• Extensive experience building both on-Prem & Cloud infrastructure at scale from scratch.
• Strong SRE mindset: SLOs, SLIs, incident response
• AI-curious or AI-native: excited to build agent-powered ops
• Someone who is currently hands on (not someone primarily focused on strategy & people management)
• Passion for open-source, clean architecture
• Software Development experience (Bonus points for Go(Golang))
• Bonus: background in financial systems, core banking, or regulated infra

Why join:

• Huge ownership: build core infra from scratch.
• Work with a high-caliber team, fast-paced and product-minded founders who have worked in some of the most recognised tech businesses in the world.
• Help define an open-source platform from day one.
• Clear path to tech unicorn status with fruitful equity included.
• Recently raised 8 figures in funding.
