Description du poste

Job Description

This position is in Blockchain team.

Zama recently unveiled the Zama Confidential Blockchain Protocol, which enables confidential smart contracts on top of any blockchain L1 or L2 using Fully Homomorphic Encryption (FHE). The Zama Developer Platform (ZDP) is our managed gateway that lets internal teams and external developers use the open-source Zama Protocol through simple, authenticated HTTPS endpoints. Think Infura or Alchemy, but confidential by default.

We are looking for a hands-on DevOps/Site Reliability Engineer (SRE) to design, build, and operate the cloud and platform foundations of ZDP. You will help shape the front door to Zama’s privacy-preserving technology. Your work will remove complexity for developers, accelerate internal iteration, and underpin how confidential applications get built and scaled.

What you will do

• Own and operate the Zama Developer Platform API management layer and developer portal, including API key lifecycle, rate limits, quotas, and tenant policies.
• Write and maintain small services, CLIs and gateway plugins for the platform, primarily in Go or Rust, with tests and code reviews.
• Build reliable CI/CD, environment isolation, and release automation that supports frequent, safe changes for ZDP Relayer, client SDKs, and other components.
• Establish end-to-end observability with structured logs, metrics, traces, SLOs, and actionable alerting, then iterate based on what you learn.
• Deliver security-by-default: least-privilege access, secrets management, strong authentication on admin surfaces, audit trails, and appropriate edge protections.
• Create and maintain runbooks, contribute to on-call and incident response, and drive post-incident improvements.
• Reduce toil by automating runbooks and incident tooling, including load and failure testing.
• Profile performance and cost across the stack and make pragmatic optimisations.
• Shape our approach to multi-region and horizontal scaling, including data residency considerations such as GDPR and disaster recovery.
• Collaborate widely, contribute to technical direction, and help improve engineering practices over time.
