Staff Rails Engineer

We're looking for a Staff Backend Engineer to own and scale the Ruby on Rails layer of our AI-native data platform. You'll be responsible for the core B2B SaaS experience: dashboards, APIs, auth, permissions, and the product surface that both humans and AI agents rely on every day.

• 7+ years of backend engineering experience, with deep experience in Ruby on Rails

• Strong track record building B2B SaaS products with complex dashboards and workflows

• Deep understanding of PostgreSQL (schema design, migrations, performance, data integrity)

• Hands-on experience designing and operating APIs at scale

• Solid knowledge of authentication & authorization systems (OAuth, SSO, permissions)

• Strong grasp of system design, API boundaries, and long-term architectural trade-offs

• Product-minded, autonomous, and comfortable operating with high ownership and ambiguity

Bonus points

• Experience with multi-tenant SaaS architectures

• Built or maintained design-system-backed dashboards used by technical and non-technical users

• Familiarity with event-driven systems and background job processing (Sidekiq, Faktory, etc.)

• Experience working closely with frontend teams (React, GraphQL clients)

• Exposure to AI-powered features or systems used by automated agents

• Prior work in data, analytics, or developer tooling

• Own the Rails backend powering our B2B SaaS product and internal APIs

• Design and evolve a clean, expressive GraphQL API used by both the web app and AI agents

• Build robust systems for auth, permissions, organizations, billing, and environments

• Partner with frontend engineers to deliver high-quality dashboards and workflows

• Ensure correctness, performance, and maintainability of our Postgres data models

• Make architectural decisions that balance product velocity and long-term scalability

• Shape engineering culture, raise the bar on code quality, and mentor others

• Act as a technical owner for large product areas, from conception to production
