The Role

We're looking for a Senior Full Stack Engineer responsible for systems — from the user-facing experience to the services and AI-powered APIs that bring it to life. Our stack spans Django, Angular, Postgres, and AWS, and we're leaning into AI on two fronts: to amplify how our engineering team builds and ships, and to deliver new AI-powered capabilities that make our customers dramatically more productive. You'll partner closely with product managers, designers, and fellow engineers to shape what we build and how it comes together. Planning, shipping, and learning are the traits we value most — along with the judgment to own a system end-to-end and make it better with every release.

Responsibilities:

Full Stack Feature Delivery - Discuss, plan, design, build, and ship features across the full stack - from polished user-facing interfaces to the backend services and AI-powered APIs that drive them. Work on capabilities that thousands of businesses rely on every day.

System Ownership - Own the end-to-end quality of your system, including quality, reliability, performance, and the user experience your work delivers. Help evolve the architecture as we migrate modules into independent services.

Cross-Functional Collaboration - Partner with engineers, designers, product managers, and other stakeholders to define both the user experience and the technical approach that brings it to life.

Quality and Craft - Manage code reviews through Pull Requests and uphold a culture of moving fast while maintaining strong unit tests and code quality. Triage and fix bugs, often working directly with users to understand the problem and close the loop.

Get Creative with AI - Use AI tools, workflows, and automations to accelerate how you design, write, test, and ship - and bring that same sensibility to the AI-powered features we build for our customers.

Requirements

The ideal candidate should have…

• 6+ years of professional experience building web applications using modern software engineering processes.
• Proficiency in Python and Django on the backend.
• Proficiency in working on the front end, ideally with Angular, with hands-on experience working within a design system or shared component library.
• Experience using AI coding tools (Claude Code, Cursor, or similar) as part of their daily workflow - and a point of view on where they help and where they don't.
• A track record of building performant and scalable systems across both frontend and backend, making pragmatic tradeoffs, with prior work to point to.
• The instinct to debug complex issues wherever they live - from frontend rendering quirks to database performance problems.
• A habit of thinking critically about your work and asking questions to improve the product, not only on its technical implementation but also on how well it serves users' needs.
• Strong communication skills, with the ability to explain complex technical topics clearly to the entire team.
• An eagerness to jump in when things inevitably break and drive issues to their root cause.

Nice to haves:

• Fintech, accounting, or ERP integrations experience.
• Experience building features powered by LLMs or AI APIs.
• Familiarity with AWS and modern DevOps practices.
• Product sense - an instinct for what makes a feature genuinely useful.
• Required Skills
• Angularpython
