This position is in Zama’s Developer Platform 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 Principal Platform Engineer to take ownership of our platform architecture and establish the technical vision for our developer portal, API management layer, and relayer/oracle backends. You will be the authority on API standards, reliability, and security, directly shaping a scalable and trusted platform through your deep expertise and technical leadership.

What you will do

• Own platform architecture & API governance: Define gateway policies (auth, rate limits, quotas), versioning/deprecation, multi-tenancy and abuse protections, request/response contracts, idempotency, and error semantics. Make crisp trade-offs that keep delivery moving under real deadlines.

• Uplevel software practices via code reviews & standards: Lead cross-repo reviews and mentorship across our developer portal, API management layer, and relayer/oracle services to elevate technical excellence.

• Drive reliability & release engineering: In partnership with SRE/DevOps and QA, set SLOs, error budgets, and actionable alerting; implement CI/CD, canary deployments, and safe rollbacks; and ensure on-call readiness with clear runbooks.

• Deliver security-by-default: Architect OIDC/OAuth2 flows, secure token lifecycles, least-privilege IAM, secrets management, audit trails, and robust edge protections.

• Shape metering & billing foundations: Ensure accurate usage capture and reconciliation for usage-based products; lead the integration with billing engines like Stripe.

• Guide on-chain ↔ off-chain integration: Set patterns for reorg-aware relayer and oracle services (owned by Dev Platform); collaborate with the Zama Protocol team on contract interfaces and upgrade cadence.
