Senior / Staff Software Engineer, Infrastructure

Role details

ABOUT THE ROLE Join a small team building AI-powered products and infrastructure for business users. You will own major product modules end to end, turning open-ended goals into simple, production-ready tools that customers can use independently. WHAT YOU'LL DO - Build and own user-facing products across AI agents, app building, mobile experiences, and headless SaaS capabilities such as identity, content management, files, email, and commerce. - Take ownership of broad product areas, shaping solutions from initial goals through launch and refinement based on user feedback. - Partner with company leadership to define requirements and iterate on products for technical and non-technical users. - Design straightforward experiences that help users manage critical business systems. - Lead features through product design, architecture, data modeling, API design, production launch, and post-launch iteration. - Build core SaaS capabilities including billing, entitlements, analytics, experimentation, feature flags, internationalization, and notifications. - Use AI coding tools in your daily development workflow to work efficiently and move quickly. WHAT WE'RE LOOKING FOR - Typically 2 to 10 years of experience in infrastructure, platform, or backend engineering, with demonstrated growth into senior or staff-level scope. - Strong full-stack skills, especially frontend development, with experience using TypeScript, React, and production databases such as Postgres, Redis, or ClickHouse. - Evidence of owning and shipping a complete product module, not only small features or bug fixes. - Production experience with Temporal or a comparable durable workflow orchestration system. - Experience managing infrastructure as code with CDK or Terraform and orchestrating server or container fleets using tools such as Kubernetes or Docker on AWS. - Strong production database skills, including schema design, scaling, and performance tuning. - Daily experience with AI coding tools and the ability to explain your workflow. - At least one year at a fast-growing startup or high-bar product or developer tools company, or relevant founder experience. - Experience building infrastructure for AI agents or machine learning workloads is a plus.
