Authorium | Full-Stack Engineer (Mid & Senior) | San Francisco, CA | ONSITE (Mon-Thu hybrid) | Full-time | $148k-230k + equity | https://authorium.com

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.

*Scribd | Lead Product Manager, AI Developer Platform | US, Canada | REMOTE*

Scribd, Inc. is on a mission to advance human understanding. Our four products — Scribd®, Slideshare®, Everand™, and Fable — help billions of people across the globe move beyond access and into insight, application, and expertise. We're a YC '06 company — one of the oldest still around — running one of the largest Ruby on Rails sites, serving 200M+ unique visitors a month with 2M+ paying subscribers.

I'm hiring a PM to own our *AI Developer Platform* — the internal product 200+ engineers build on every day. The platform spans the full agentic stack: the tools in each engineer's hands (Claude Code), a plugin marketplace and a library of skills that extend them, an internal app platform and agent runtime that teams build on, and the evals, canonical context, and conventions that make agents reliable across a polyglot codebase (Ruby, Go, TypeScript, Python; AWS/Databricks). You'll own the product strategy for developer experience and how we measure it, partnering directly with the Developer Platform and Data Platform engineering teams who build the underlying capabilities.

We're looking for a highly technical PM — quite possibly a former engineer — who is genuinely passionate about how developer platforms are evolving in the age of AI. You've shipped real products with modern agentic primitives (agents, evals, tool use, MCP, plugins/skills), and you can hold your own with engineers in technical discussions. This is the first PM seat at Scribd pointed inward, in a brand-new domain with no playbook to inherit. Reports to me (Director, Developer Platform).

Friendly, people-first, engineering-driven culture with competitive salary, great benefits, and real work-life balance.

Apply: https://jobs.ashbyhq.com/ScribdInc/ff2680ea-9a6d-436d-bdb0-3... — or email me directly at cktaylor at scribd.com (I've hired off these threads before). Recruiters/agencies, please don't.

Treasure AI | Staff Engineers (Fullstack/Backend) | HYBRID (Tokyo & Vancouver) | Full Time | https://www.treasure.ai/

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.

We need three Staff Engineers (two in Tokyo, one in Vancouver) to act as technical anchors. You’ll be a great fit if you’re a backend/distributed systems engineer who can architect a clean React frontend, or a pure distributed systems specialist happy to collaborate across the full stack.

The roles primarily deal with architecting systems to process and personalize massive marketing datasets in near real time, with a strong emphasis on being able to work cross functionally to deliver best-in-class agentic interactions deeply integrated with our systems.

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