Member of the Technical Staff - Platform Engineer

OpenCoreOS•London, NY

About The Position

About OpenCoreOS A "Thin Ledger," not a thick core: We provide a hyper-performant ledger using Go, Rust, and multi-region distributed databases. This gives banks a simple, powerful, and open foundation to build on, not a monolithic cage AI-native by design: AI isn't an add-on; it's woven into our fabric. We use it to power autonomous operations, create agentic development workflows, and build an intelligent, self-healing system Unbreakable and open: We engineer for five-nines reliability and bulletproof consistency, targeting the scale of a Tier-1 bank managing hundreds of millions of transactions daily. By building on open technologies and shaping new standards, we ensure our platform provides a foundation for innovation, not another form of lock-in Backed by proven industry builders: Our leadership team combines the strategic insight of ex-McKinsey banking, product, and engineering experts with the battle-tested experience of a founder who built and scaled a mission-critical enterprise fintech company serving the world's largest banks. This is paired with the firsthand operational knowledge of former global bank CIOs, giving us an unparalleled understanding of the market we are redefining What You Will Do Infrastructure: Build and scale multi-region Kubernetes infrastructure (EKS/GKE/AKS) for five-nines workloads. Architecture: Architect active-active distributed systems. GitOps: Implement Terraform, Helm, and GitOps (Flux) across cloud and hybrid environments. Resiliency: Own DR, failover, backup/restore, and multi-region resiliency. Security: Drive zero-trust security, identity, multi-tenant isolation, and cryptographic audit trails. Observability: Build and maintain stacks using Prometheus, Grafana, Loki and OTEL. AI-SRE: Lead AI-driven automation (auto-remediation, incident insights, AI-based root cause analysis). Deployment: Support on-prem/air-gapped deployments and legacy integrations. Why join us? Massive impact: Transform how T1 banks handle billions of transactions daily—on a truly open platform. High-caliber team: Join a small team of exceptional engineers who value both speed and stability. AI-native workspace: Experience an AI-first environment with LLMs integrated into every tool.
