Senior Platform Engineer

As a Senior Platform Engineer, you’ll shape the tools and systems that help engineers move faster, build smarter, and deliver high-quality software at scale. You’ll work at the intersection of developer experience, platform engineering, and AI-driven innovation, creating solutions that improve how teams build, test, review, and ship code. From modernizing workflows to introducing intelligent automation, you’ll help raise the bar for engineering efficiency across the organization. You’ll also play a key role in influencing technical direction, strengthening development standards, and making everyday engineering work more seamless and effective.

• You’ll design and build developer-focused tools and services that improve the software development lifecycle, including workflow automation, continuous integration and continuous delivery enhancements, and integrated development environment or tooling integrations.
• You’ll implement AI-driven capabilities across engineering workflows, including code assistance, documentation generation, test automation, and code review support.
• You’ll improve the developer experience by identifying friction points, streamlining workflows, and delivering scalable solutions that increase engineering productivity.
• You’ll promote best practices for developer tooling, local development environments, and platform adoption through clear documentation, practical examples, and hands-on support.
• You’ll design, deploy, and maintain the core AI platform infrastructure to enable the safe, efficient, and observable operation of production grade AI agents.
• You’ll participate in design and architecture discussions, contribute thoughtful technical guidance, and help strengthen engineering standards across teams.
• You’ll collaborate closely with engineers and cross-functional partners to deliver reliable, maintainable systems that support long-term platform growth.
