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.
