Senior DevOps / Infrastructure Engineer (Americas, US time zones)

Startale builds onchain finance products including blockchain networks, stablecoins, payments, and consumer applications. The Senior DevOps / Infrastructure Engineer will own the architecture, deployment, operation, security, and reliability of production infrastructure supporting StartaleApp, Strium, and other ecosystem products during US time-zone coverage.

Responsibilities:

• Own infrastructure architecture and operations for StartaleApp, Strium, and other production systems
• Design, build, and operate highly available cloud infrastructure on AWS: Kubernetes clusters, networking, storage, scaling, upgrades
• Manage everything as code: Terraform, GitOps, and CI/CD pipelines with safe rollouts and rollback
• Operate PostgreSQL in production: availability, replication, backups, performance, recovery
• Build observability across infrastructure, applications, databases, and blockchain nodes, with alerting that catches incidents early
• Run blockchain infrastructure (nodes, RPC services, indexers) and monitor it down to protocol level: sync, connectivity, transaction processing
• Design disaster recovery and failover for critical systems, and harden security: access control, secrets, vulnerability management, monitoring
• Diagnose production incidents across the full stack, and remove operational bottlenecks with automation instead of manual procedure

Requirements:

• You must be physically based in a US time zone (UTC-8 to UTC-5), whether in the US, Canada, or Latin America
• 5+ years in DevOps, SRE, platform, or infrastructure engineering
• A track record of building and operating production infrastructure for highly available systems, where availability directly affected users or the business
• Deep hands-on Kubernetes, AWS, and Linux experience
• Infrastructure as code with Terraform, GitOps practices, and CI/CD pipeline design
• Solid networking fundamentals: DNS, load balancing, TLS, service discovery
• PostgreSQL in production: replication, backups, recovery, performance
• High-availability design, incident response, root-cause analysis, and capacity planning
• Hands-on experience operating blockchain infrastructure (nodes, RPC, indexers, validators, or data pipelines) and an understanding of how distributed blockchain networks fail
• SecOps or cloud security experience, hardening production environments, AWS security services and IAM design
• bare-metal operations, Helm or ArgoCD, messaging systems such as Kafka or NATS, observability stacks such as Prometheus, Grafana, Loki, or OpenTelemetry
• operating chain infrastructure at significant scale; Ethereum, Polkadot, or L2 ecosystems
• financial, trading, or other latency-sensitive systems; using AI tools in infrastructure workflows; Go, Rust, or TypeScript
