This company builds the intelligence layer that intercepts scams before payments clear. They protect major banks from fraud in real‑time, a high‑stakes problem with immediate impact. Backed by leading investors, they're rapidly expanding their platform internationally. You'll be the first dedicated DevOps Engineer, owning the reliability of a 24/7 investigation engine that runs on live payment flows. This isn't a maintenance role; it's about building the foundations for AI‑native infrastructure, defining incident response culture, and evolving a complex Terraform estate on GCP. You'll solve a harder version of the observability problem: monitoring non‑deterministic AI agents where “correct” isn't always identical.
The work
- Design and implement observability for a 24/7 real‑time system, specifically tackling the challenge of non‑deterministic AI agents.
- Own the Terraform estate on GCP, evolving infrastructure as the platform scales to new financial institutions.
- Define and embed the incident response culture, building processes that ensure rapid resolution and continuous improvement.
- Build and refine CI/CD pipelines, ensuring high deploy velocity without compromising safety for a fast‑moving engineering team.
- Establish security best practices across the infrastructure, from network security to secrets management, making secure‑by‑default the standard.
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 with Terraform, managing complex production infrastructure on a major cloud provider (GCP preferred).
- A proven track record designing and implementing observability for distributed systems, ideally including non‑deterministic or ML‑powered components.
- Hands‑on experience with incident response, including on‑call duties, leading incidents, and building robust processes.
- Strong foundations in infrastructure security: network, access control, secrets management, and secure‑by‑default principles.
