Senior / Staff Software Engineer, Infrastructure
Confirmed on the employer's own hiring board on Oct 29, 2026. First seen by Alion on Oct 27, 2026.
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.
