About The Position

Our client is hiring a Senior Platform Engineer to improve the systems engineers use to build, deploy, observe, and operate production software. This role owns engineering enablement across the company. You’ll build the environments, tools, workflows, infrastructure, and standards that help engineers — and coding agents — understand the codebase, make changes, validate work, and ship safely. This is a high-impact role for someone who enjoys platform engineering, developer experience, infrastructure automation, observability, and building systems that make engineering teams faster without sacrificing safety or reliability.

Requirements

5+ years of relevant platform, infrastructure, DevOps, SRE, or backend engineering experience
Experience building and operating production systems on AWS
Strong knowledge of containers, infrastructure as code, CI/CD, networking, and observability
Experience with container orchestration and automated delivery workflows
Experience improving developer environments, CI performance, service templates, or internal engineering tools
Ability to write software and automation rather than relying on manual procedures
Daily experience with coding agents or AI-assisted development tools
Evidence of building tools, context, documentation, or workflows that make coding agents more reliable
Experience measuring or improving engineering throughput, CI time, test quality, or self-service adoption
Experience diagnosing production incidents and driving follow-up improvements
Strong judgment across reliability, security, cost, and delivery speed
Clear communication skills across engineering teams

Nice To Haves

Experience with AI infrastructure or AI-native engineering workflows
