Senior Full Stack Engineer (Frontend), Agentic AI Applications

About the role

We're building the next generation of the Auditoria platform and there is a lot of surface area to cover. As a Full Stack Engineer with a strong frontend focus, you'll own a significant portion of the UI layer powering our AI-driven finance automation platform, while having enough backend fluency to unblock yourself when needed. This isn't a role where the frontend is an afterthought. The full scope of what needs a great UI is substantial: workflow builders, action libraries, observability dashboards, low-code tooling, data type management, and more. You'll be deeply involved in shaping how enterprise finance teams interact with sophisticated AI/ML systems translating complex capabilities into polished, intuitive interfaces that users actually love.

We're looking for someone hungry to own their work end-to-end, collaborate closely with product, design, and backend engineers, and move fast without sacrificing quality. Key Responsibilities:

• Frontend (Primary 70%): Build and maintain a scalable, enterprise-grade design system and component library using React and TypeScript
• Develop rich, interactive UIs for core platform surfaces, including: Workflow creation: low-code builders, auto-complete, agent flow visualization, and more
• Action definitions: creation, discovery, and installation from a library
• Testing, logging, and observability: dashboards and tooling for monitoring AI agent behavior
• Data type management: resolvers, masking, references within workflows and actions
• Translate high-fidelity design mockups into polished, production-ready components with strong attention to detail: loaders, empty states, micro-interactions, and motion
• AI-powered "SmartBot" interfaces that surface intelligent automation for AP/AR, vendor management, procurement controls, and inbox triage for the Office of the CFO
• Champion frontend quality, maintainability, and performance across the team
• Backend (Supporting 30%): Expose and consume REST endpoints and integrate with internal APIs to support frontend features
• Collaborate with backend engineers on data contracts, API design, and integration points
• Unblock yourself on backend tasks: debugging, light service work, or wiring up new resources without needing to hand off for every integration

Qualifications

• 5+ years of software engineering experience, with a clear frontend-heavy track record (3+ years considered for candidates with strong internship or co-op experience)
• Deep proficiency in React and TypeScript, including component architecture, state management, and performance optimization
• Experience building or contributing to design systems, including theming, tokenization, and reusable component patterns
• Comfortable working with REST APIs (reading, writing, and debugging integrations on both sides of the stack)
• Strong ownership mentality with a demonstrated history of driving features from design to production
• Collaborative by nature (you work closely with designers, PMs, and engineers and leave things better than you found them)
• Must be currently authorized to work in the United States without employer sponsorship, as we are unable to sponsor or transfer visas for this position

Preferred Qualifications

• Experience with low-code or workflow builder UIs (node-based editors, drag-and-drop frameworks, visual DAG tools, etc.)
• Familiarity with AI-powered or ML-integrated products, and comfort surfacing complex backend data in intuitive UI patterns
• Background in FinTech, B2B SaaS, or enterprise finance environments
• Exposure to observability or developer tooling products (logging UIs, monitoring dashboards, etc.)
• Some experience with Python or backend services (FastAPI, Node.js, etc.)
