Senior Infrastructure Engineer

You'll build and run Somnia's key backend services, including the L1 and node fleet, RPC and indexing layers, product backends, and developer-facing services that teams depend on. This is an SRE-minded role where you make reliability measurable, rollouts safe, and infrastructure repeatable, so every team can move fast without breaking things. You'll treat infrastructure as a product: automating relentlessly, measuring everything, and leveraging AI to accelerate development, operations, and incident response. You'll rotate between embedding with engineering teams and building the shared platform, tooling and operational standards that underpin the wider organisation.

Responsibilities

• Define and maintain SLOs, SLIs, and error budgets
• Build observability including metrics, logs, traces and alerts that catches regressions before users do
• Build repeatable, self-service infrastructure through infrastructure-as-code, CI/CD and golden paths
• Own rollouts end-to-end including progressive delivery, canaries, safe migrations and clean rollbacks
• Operate the systems behind Somnia's nodes, validators, RPC and indexing, tuning for performance and cost across regions
• Lead incident response and on-call
• Run blameless postmortems and continuously harden the platform
• Partner with product and protocol teams to design and operate production-ready services

Requirements

• Strong experience operating production infrastructure at scale (cloud and/or bare metal), with deep Linux fundamentals
• Experience with infrastructure-as-code such as Terraform or Pulumi, alongside configuration management
• Experience running containers and orchestration platforms (Docker, Kubernetes) in production
• Strong programming skills, ideally in Go and/or TypeScript, for building automation and internal tooling
• Experience with observability stacks (Prometheus, Grafana, OpenTelemetry or equivalents)
• Experience operating and monitoring distributed systems, including capacity planning and performance tuning
• Comfortable operating in high-stakes production environments and responding to incidents
• Genuine interest in crypto and on-chain systems
• Experience operating blockchain node infrastructure (validators, RPC, archive nodes) for an L1/L2
• Experience with high-performance networking, low-latency systems or load balancing at scale
• Multi-region and geo-distributed deployments with failover strategies
• Security and key management (HSMs, secrets management, hardening)
• EVM tooling and the wider Web3 infrastructure ecosystem

Benefits

• Remote work
• Token incentives
