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

As a Senior DevOps / Infrastructure Engineer at Startale, you own the infrastructure, deployment, and operational systems behind StartaleApp, Strium, and other products across the Startale ecosystem. You design, build, and operate production infrastructure end to end, from cloud and Kubernetes to CI/CD, databases, observability, and security. You will anchor infrastructure coverage in US hours for a globally distributed engineering team, serving as the infrastructure owner awake when most of the team is not.

What you'll do

• 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, and upgrades.
• Manage everything as code using Terraform, GitOps, and CI/CD pipelines with safe rollouts and rollback.
• Operate PostgreSQL in production: availability, replication, backups, performance, and 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, and transaction processing.
• Design disaster recovery and failover for critical systems, and harden security: access control, secrets, vulnerability management, and monitoring.
• Diagnose production incidents across the full stack, and remove operational bottlenecks with automation instead of manual procedure.

What you bring

• 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 experience with Kubernetes, AWS, and Linux.
• Infrastructure as code with Terraform, GitOps practices, and CI/CD pipeline design.
• Solid networking fundamentals: DNS, load balancing, TLS, and service discovery.
• PostgreSQL in production: replication, backups, recovery, and performance tuning.
• 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.
• You must be physically based in a US time zone (UTC-8 to UTC-5), whether in the US, Canada, or Latin America.

Nice to have

• SecOps or cloud security experience, hardening production environments, and AWS security services and IAM design.
• Bare-metal operations, Helm or ArgoCD, messaging systems such as Kafka or NATS, or observability stacks such as Prometheus, Grafana, Loki, or OpenTelemetry.
• Operating chain infrastructure at significant scale, particularly in Ethereum, Polkadot, or L2 ecosystems.
• Experience in financial, trading, or other latency-sensitive systems, using AI tools in infrastructure workflows, or programming in Go, Rust, or TypeScript.

What we offer

• Competitive compensation and equity.
• Remote work in US time zones.

About Startale

Startale builds onchain finance as a vertically integrated stack: the chains, a JPY stablecoin, payments, and a consumer app. With SBI Group they are building Strium, a fully onchain exchange; they issued JPYSC, Japan's first trust-licensed JPY stablecoin; with Sony Group they operate Soneium; and StartaleApp, used by 210k monthly users, serves as the front door to all of it. The team is approximately 70 people across 20 nationalities, with English as the working language of engineering.
