About North:

It offers a secure and customizable environment, allowing companies to deploy AI while maintaining control over sensitive data. North integrates seamlessly with existing workflows, providing a trusted platform that connects AI agents with workplace tools and applications.

Why this role:

The Data Abstractions & Tools team is the group inside North responsible for how users bring their data into the platform and put it to work. We own the systems that let users upload, organize, and share their files and knowledge bases, the framework for extending agents with skills and third-party integrations, and the data-sync pipeline that connects enterprise data sources to North's agents.

We are a small team owning a wide surface area, and we need a senior generalist who can move freely across backend and frontend as the roadmap demands. You will pick up any layer of a feature, from API design and database schema to the frontend that sits on top of it, and own it end-to-end.

In this role, you will:

• Design, build, ship, and maintain features across the full stack for our roadmap surfaces: large-scale file upload and management, shared knowledge bases, the agent extensibility framework (skills and integrations), and the pipeline that syncs external enterprise data into the platform.
• Own features end-to-end, from technical design through implementation, testing, launch, and iteration.
• Write and ship minimal code that runs in low-resource environments with stringent deployment mechanisms. As security and privacy are paramount, you will sometimes need to re-invent the wheel and won't be able to use the most popular libraries or tooling.
• Collaborate closely with Product, UX, and the modeling team to validate requirements and prototype quickly.
• Raise the engineering bar: patterns, testing discipline, code review, and mentoring across the team.
• Use AI actively in your work, while staying accountable for the quality and reliability of what you ship.

You may be a good fit if:

• Have shipped (lots of) fullstack code (Python and React) in production
• You excel in fast-paced environments and can execute while priorities and objectives are a moving target
• You have strong coding abilities and are comfortable working across the stack.
• You have built and deployed extremely performant client-side or server-side RAG/agentic applications to millions of users.
• You think like a product owner, not just an engineer. You ask "should we build this?" before "how do we build this?"
• You have strong opinions on what makes a great user experience and aren't afraid to push back on designs or specs that don't serve the user.
• You've owned features end-to-end: from understanding the user problem, to shipping, to measuring impact.
