Senior DevOps / Infrastructure Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior DevOps / Infrastructure Engineer based in United States . As a Senior DevOps / Infrastructure Engineer, you will own the infrastructure, deployment, and operational systems supporting high-scale products across a rapidly evolving technology ecosystem. You will design, build, and operate production infrastructure end to end, spanning AWS, Kubernetes, CI/CD, databases, observability, security, and distributed systems. The role is highly hands-on and gives you significant ownership over architectural decisions and operational reliability. You will support demanding user-facing and financial technology products operating under high availability, security, throughput, and latency requirements. Experience with blockchain infrastructure is particularly valuable, while cloud security or SecOps expertise is a strong advantage. Working as the infrastructure owner during US hours, you will provide critical operational coverage across a globally distributed engineering organization.

Own infrastructure architecture and operations across production applications and services, including cloud, Kubernetes, databases, deployment systems, and blockchain infrastructure. Design, build, and operate highly available AWS environments, including Kubernetes clusters, networking, storage, scaling, upgrades, and related infrastructure services. Manage infrastructure as code using Terraform and GitOps practices, while designing and maintaining CI/CD pipelines that support safe deployments and reliable rollbacks. Operate PostgreSQL databases in production, with responsibility for availability, replication, backups, recovery, and performance optimization. Build comprehensive observability across infrastructure, applications, databases, and blockchain nodes, including monitoring and alerting capable of identifying incidents early. Operate blockchain infrastructure such as nodes, RPC services, and indexers, monitoring systems at the protocol level for synchronization, connectivity, and transaction processing. Design disaster recovery and failover strategies for critical systems while strengthening security through access controls, secrets management, vulnerability management, monitoring, and related safeguards. Diagnose complex production incidents across the full technology stack, from Kubernetes and networking through databases and blockchain systems. Identify recurring operational bottlenecks and replace manual procedures with reliable automation. Contribute to architectural decisions and long-term infrastructure strategy, treating infrastructure as a product with defined reliability, maintenance, and user requirements. Requirements 5+ years of professional experience in DevOps, SRE, platform engineering, infrastructure engineering, or a closely related discipline. Proven track record of building and operating production infrastructure for highly available systems where reliability directly impacts users or business operations. Deep hands-on experience with Kubernetes, AWS, and Linux. Strong infrastructure-as-code experience with Terraform, combined with GitOps practices and CI/CD pipeline design. Solid networking fundamentals, including DNS, load balancing, TLS, and service discovery. Strong production PostgreSQL experience covering replication, backups, recovery, performance, and availability. Experience with high-availability architecture, incident response, root-cause analysis, and capacity planning. Hands-on experience operating blockchain infrastructure such as nodes, RPC services, indexers, validators, or blockchain data pipelines. Understanding of how distributed blockchain networks operate and how they can fail under real-world conditions. Strong ownership mindset, with the ability to take responsibility for problems from architecture through production. Comfortable designing for high load and partial failure and automating recurring operational tasks. Strong diagnostic and problem-solving skills across multiple infrastructure layers. Security or SecOps experience, including production environment hardening, AWS security services, and IAM design, is a strong asset. Experience with bare-metal operations, Helm or ArgoCD, messaging systems such as Kafka or NATS, or observability tools including Prometheus, Grafana, Loki, or OpenTelemetry is an asset. Experience operating blockchain infrastructure at significant scale, particularly within Ethereum, Polkadot, or Layer 2 ecosystems, is a strong plus. Exposure to financial, trading, or other latency-sensitive systems is beneficial. Experience using AI tools in infrastructure workflows is a plus. Familiarity with Go, Rust, or TypeScript is an additional advantage. Must be based in a US time zone (UTC-8 to UTC-5) while physically located in Canada. Benefits Fully remote position for candidates based in Canada and working within the required US time-zone range. Opportunity to own infrastructure supporting high-scale applications and distributed systems. Broad technical scope spanning cloud infrastructure, Kubernetes, databases, CI/CD, observability, security, and blockchain. Significant ownership and direct product impact within a small, highly technical engineering team. Opportunity to work on infrastructure supporting a decentralized exchange designed for high-throughput and low-latency trading. Exposure to complex distributed systems and production environments operating under demanding reliability and security requirements. Competitive compensation. Equity opportunity. Collaboration with a globally distributed engineering team working across multiple regions and time zones.
