-- Senior Full Stack Engineer — C$180k–200k

Own major product surfaces end-to-end, from talking to customers and scoping through architecture, implementation, and iteration. No PM layer — engineers closest to the problem own the solution. Looking for 8–10 years full stack, deep React/Next.js, strong Node.js in production at scale, advanced Postgres (multi-tenant, query optimization), auth/RBAC in multi-tenant B2B, and BullMQ or similar (Sidekiq, SQS, Temporal). Real product instincts required.

You may know us from our open-source roots (Fluentd/Embulk.) We’re an enterprise CDP and agentic experience platform that unifies fragmented customer data from multiple sources and allows for complex marketing workflows. Our engineering team is distributed across Canada, Japan, and the USA.

Our core stack is Rails, Typescript/Lambda, React, and Kotlin.

We're building the operating system for the digital infrastructure of government. Authorium is a GovTech SaaS platform that unifies the messy, high-stakes workflows (procurement, grants, budgeting) that keep state and local governments running. We replace fragmented docs, spreadsheets and decades-old legacy systems with a unified data layer managing billions in public funds. Customers include California's CDSS, CalPERS, and EDD, plus major agencies in NY, Florida and Washington.

We're >40 people, growing 45% YoY, with a clear path to profitability in 2026. Real product-market fit, scale, and impact.

We're standing up our SF office as the war room for our hardest problems: modularizing our core domain, designing the next-gen workflow engine, building versioning and approval systems that hold up across dozens of customer configurations. You'd whiteboard, debug, and ship in person alongside a high-caliber team.

Stack: Ruby on Rails BE, Hotwire and Next.js FE, enterprise form and document capabilities. We're leveraging AI in our development process: Claude Code for specs, agentic testing, automated reviews.

Two roles open:

- Full-Stack Engineer (3+ yrs) | $148,750-$201,250 + equity | https://jobs.ashbyhq.com/Authorium/b59ff28c-3e3c-4190-abaa-a... - Senior Full-Stack Engineer (6+ yrs) | $170,000-$230,000 + equity | https://jobs.ashbyhq.com/Authorium/dc83e0dd-9279-4381-9930-f...

Both value deep fundamentals (system design, database optimization, clean architecture) over specific syntax. Bonus for Rails, document-heavy systems, or regulated-industry experience (GovTech, FinTech, HealthTech).

Benefits: 100% employee coverage, 401(k), flexible PTO, home office + commuter stipend.
