Senior Site Reliability Engineer (SRE) I

About Consensys

Consensys Incorporated is an independent blockchain infrastructure company, spun out of Consensys Software Inc. — one of the world's leading blockchain technology companies and the primary development organization behind the Ethereum ecosystem.

We build and operate neutral, institutional-grade blockchain infrastructure that connects banks, asset managers, custodians, and financial market infrastructures to digital asset networks, meeting the non-negotiable standards of institutional finance: privacy, scalability, resilience, security, and regulatory readiness.

Headquartered in Miami, Florida, and operating across the US, Europe, and Australia, Consensys Incorporated launched as an independent entity in September 2026 and is building the team to match its ambition.

Why this role exists

Consensys Incorporated operates production blockchain infrastructure for financial institutions. Those networks don't stop at 18:00 CET, and today our infrastructure team sits mostly in Europe. This role closes that gap: you are our engineer on the ground when Europe is asleep.

This is a coverage-first role. Roughly 60% incident response, monitoring and operational hardening; 40% build work on the platform. If you want a pure greenfield engineering job, this isn't it — but you will be the first person in the timezone, which means you help design the rota rather than inherit it.

What you'll own

• Front-line operational coverage for production networks during APAC hours — monitoring, triage, escalation, and running incidents to resolution.

• Participation in (and help designing) a follow-the-sun on-call rota alongside the European team, replacing the arrangement we're transitioning off.

• Deployment and maintenance windows scheduled in APAC hours: node upgrades, chain releases, coordinated maintenance.

• Runbooks, alert tuning and observability improvements — specifically, turning the things you get paged for into things nobody gets paged for.

• Platform build work between incidents: Kubernetes, GitOps, IaC, CI/CD pipelines.

• Being the operational contact for APAC-based client and partner teams.

First 90 days

• Ramp on the stack. Realistically this takes three months — Kubernetes, ArgoCD/GitOps, Ethereum clients, the Linea stack (sequencer, coordinator, prover), ZK proving. We will not put you on a pager before you're ready.

• Shadow European incidents, then run them.

• Take the first APAC on-call shift and write the runbook gaps you find.

What we are looking for

• 4+ years in DevOps/SRE/platform engineering, including real production on-call for a system with an external SLA.
