Senior DevOps / Infrastructure Engineer (Americas, US time zones)
Startale Group, Remote
The role
Remote (Americas, US time zones) · Full time
We are looking for a Senior DevOps / Infrastructure Engineer to own the infrastructure, deployment, and operational systems behind StartaleApp, Strium, and other products across the Startale ecosystem. This is a senior, hands-on role: you design, build, and operate production infrastructure end to end, from cloud and Kubernetes to CI/CD, databases, observability, and security.
You will work primarily on two demanding products. StartaleApp is a user-facing Web3 wallet and application platform whose backend combines traditional cloud services and databases with blockchain nodes, indexers, and transaction processing. Strium, built with SBI Group, is a next-generation decentralized exchange bringing Japanese equities onchain, with a fully onchain order book and a consensus layer purpose-built for low-latency, high-throughput trading.
Both run under high load, strict availability and security requirements, and real production conditions. We want someone who builds infrastructure rather than maintains it: comfortable making architectural decisions, automating everything that repeats, and diagnosing complex production issues. Experience running blockchain infrastructure is a significant advantage, and a SecOps or cloud security background is a major plus.
What you will 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, 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.
What you need
- 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.
