Lead Infrastructure Engineer

About the role

AtoB is building a modern payments infrastructure for the trucking and logistics industry, described as "Stripe for Transportation". It is hiring a Lead Infrastructure Engineer in Montreal to own and operate its Kubernetes (EKS) infrastructure and to shape a greenfield data platform built on modern lakehouse foundations. The role sits at the intersection of platform engineering and data engineering.

Key responsibilities

• Scope and lead large, often ambiguous technical projects that lay the groundwork for early-stage products to evolve and scale
• Own and operate the Kubernetes (EKS) infrastructure, managed via the Porter orchestrator
• Apply and enforce Kubernetes best practices: resource management, health checks, autoscaling, pod disruption budgets and graceful rollout strategies
• Tune deployments and cluster configuration for zero-downtime releases and high availability
• Design and improve CI/CD pipelines for fast, reliable and safe delivery
• Contribute to observability, alerting and incident response practices across the platform

Required profile

• 8-12 years of experience
• Deep expertise in Kubernetes, including production operations, best practices and performance tuning for zero-downtime architectures
• Demonstrated hunger to learn modern data engineering topics such as lakehouse architectures, Iceberg and CDC
• Strong SQL skills and the ability to optimize queries for performance and cost
• Excellent cross-functional collaboration, including working directly with BizOps and other non-engineering stakeholders
• Ownership mindset, able to take systems from design through operation end to end

Required skills

• Strong CI/CD experience designing, building and maintaining pipelines at scale
• Nice to have: cross-region architecture (multi-region failover, DR, data replication) and cross-tenant architecture
• Nice to have: experience with Apache Iceberg, AWS Glue, EKS, Porter or similar Kubernetes management platforms
• Nice to have: familiarity with dbt, Snowflake, CDC tools (Debezium, Estuary) and fintech or regulated environments (PCI DSS, SOC 2)
