The role

This company builds the intelligence layer that intercepts scams before payments clear. Their investigation engine classifies each payment, orchestrates a live multi-source investigation using AI agents, and returns a risk decision — in real time, to major banks. This isn't a theoretical problem. It's a critical, 24/7 platform, running on live payment flows, backed by leading investors and expanding internationally.

You'll be the first DevOps Engineer, owning the reliability of this critical system. This isn't a maintenance role. It's a foundational build. You'll define what observability looks like for AI-native infrastructure, where non-deterministic agents mean traditional monitoring falls short.

You'll set the incident response culture, evolve the Terraform estate on GCP, and make deployments safe enough for a fast-moving engineering team. This is the seat where you build the infrastructure the company scales from.

The work

• Design and implement observability for a 24/7, AI-native platform where non-deterministic agents challenge traditional monitoring.
• Own the reliability of systems processing live payment flows for major banks, where downtime directly impacts fraud investigations.
• Define and embed the incident response culture, processes, and tooling for a rapidly scaling engineering team.
• Evolve the Terraform estate on GCP, ensuring infrastructure is secure by default and built for international scale.
• Build and refine CI/CD pipelines that balance rapid deployment velocity with robust rollback safety.

What You Bring

• 5+ years in DevOps or SRE, with significant experience as a first or sole infrastructure hire in an early-stage environment.
• Deep expertise in Terraform, managing complex production infrastructure on GCP.
• A track record of designing and implementing observability for distributed systems, ideally including non-deterministic or ML-powered components.
• Proven experience leading incident response, including on-call duties, incident management, and process improvement.
• Strong security foundations: network security, least-privilege access, and secrets management.
