Senior 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 Infrastructure Engineer based in Canada. This role offers the opportunity to shape the infrastructure and platforms that support large-scale, customer-facing technology products. You will take end-to-end ownership of critical infrastructure systems, from technical design and development through deployment, operation, and continuous improvement. The position combines cloud architecture, distributed systems, reliability engineering, observability, performance optimization, and developer tooling. You will partner closely with product engineering, security, and DevOps teams to build secure, resilient, scalable, and cost-efficient systems. As a senior technical contributor, you will also influence engineering practices, mentor colleagues, and help resolve complex infrastructure challenges. This is a strong opportunity for a systems-minded engineer who thrives with significant autonomy in a globally distributed, fully remote environment. Accountabilities: - Own a core infrastructure product or subsystem end to end, including design, development, deployment, operation, and production performance. - Define project goals and success metrics, align technical work with organizational objectives, and proactively identify and mitigate risks. - Translate product requirements and technical specifications into practical designs that address critical edge cases without unnecessary complexity. - Build secure, reliable, resilient, high-performing, and cost-efficient infrastructure for diverse applications and workloads. - Design, develop, and deploy production software and developer-facing tools that improve engineering workflows and reduce operational toil. - Manage infrastructure through code and configuration, primarily using Terraform and established architectural patterns.

- Partner with product engineering teams to design services for scale and resolve ambiguous technical requirements with stakeholders. - Participate in incident response and apply systematic debugging techniques to diagnose infrastructure and service issues. - Develop and improve monitoring and observability practices, using operational data to identify stability, performance, and reliability improvements. - Apply a security-focused mindset across infrastructure development, implementation, and peer reviews by proactively identifying potential vulnerabilities. - Serve as a technical resource for complex infrastructure challenges and mentor engineers through code reviews, pairing, and design feedback. - Drive collaboration across engineering and other stakeholder groups, facilitating discussions around technical decisions, processes, and infrastructure strategy. Requirements: - 6–10 years of experience in infrastructure, platform, or backend engineering, primarily within cloud-based environments; AWS experience is preferred. - Proven experience owning significant infrastructure products or subsystems through their full lifecycle, including design, implementation, deployment, and production operations. - T-shaped technical expertise, with deep specialization in one or two areas and sufficient breadth to navigate and contribute across wider systems with limited guidance. - Strong hands-on experience managing infrastructure through code and configuration using Terraform or an equivalent technology. - Deep understanding of cloud infrastructure fundamentals, including networking, load balancing, containerization, Kubernetes/EKS, and distributed systems. - Strong programming skills in Go, Python, or a comparable language, with the ability to develop production-ready software. - Hands-on production experience operating Redis or ElastiCache, including cluster and shard management, failover behavior, memory eviction policies, and scaling strategies.
