Frontend Software Engineer

Concourse builds AI agents for corporate finance teams.
We connect core enterprise data sources and deploy AI agents that can analyze the data through natural language, deliver insights in seconds, and enable our customers to make better decisions. Since launching less than a year ago, Concourse has grown extremely rapidly. Our AI agents are deployed across hundreds of high-growth companies, unicorn startups like Persona, Front, Lightmatter, and large public companies - including 2 Fortune 500 customers.
Concourse is backed by Andreessen Horowitz, CRV, YC, BoxGroup, and 50+ angel investors from companies like Brex, Rippling, Flywire, Deel, Jeeves, and DoorDash.

We’re hiring a Frontend Engineer to shape how customers interact with Concourse’s AI agents.
Your mission is to turn complex financial data and AI workflows into intuitive, fast, and delightful product experiences. You’ll build the interfaces through which finance teams explore insights, run analyses, and understand their business, and your work will define how our customers experience the power of Concourse.
You’ll work across React, TypeScript, and our design system to ship high-quality UI quickly. As an early engineer, you’ll help define frontend architecture, product patterns, and the standards for speed, polish, and craftsmanship. You’ll work directly with founders, engineering, and customers to iterate rapidly and create a world-class product surface.
This role is ideal for someone who obsesses over UI quality, loves building beautiful interfaces, and wants to play a foundational role in shaping a category-defining product.

• Craft Exceptional Interfaces: Build pixel-perfect UIs with a meticulous attention to detail and a high bar for user experience.

• Own Frontend Architecture: Develop with advanced TypeScript patterns, type-safe architectures, and clean, scalable React structure.

• Use Modern Frontend Tools: Work with Next.js, React Query, Zustand, Zod, and other modern frameworks to build fast, reliable product surfaces.

• Ship Quickly with High Quality: Move fast while maintaining performance, accessibility, and frontend best practices.

• Collaborate Closely with Customers: Engage directly with customers and users to understand feedback and translate insights into product improvements.

• Own Projects End-to-End: Take full ownership of features and projects, driving them from concept to launch with a high-ownership mentality.

• 3+ years building production React applications with a strong track record of shipping polished interfaces quickly

• Exceptional eye for detail, you care deeply about pixel-perfection, usability, and crafted UI

• Strong TypeScript skills and comfort with modern React tooling (hooks, state management, query layers, etc.)

• Self-directed builder who thrives in fast-paced, ambiguous environments with high ownership

• Excellent problem solver who enjoys breaking down complex workflows and turning them into intuitive product experiences

• Strong communicator who can work closely with engineering, design, GTM, and customers

• Experience with AI or enterprise SaaS (preferred but not required)

• Experience with full-stack or Node.js development (preferred but not required)

Joining Concourse is an incredible opportunity to get in at the ground level of a high-growth, category-defining AI company. Every person we hire meaningfully shapes the product, culture, and trajectory of the business, and we compensate accordingly with top-of-market salary and equity.
You’ll have a high degree of ownership from day one. We move fast, build aggressively, and operate with very little bureaucracy. You’ll work directly with the founders and engineering team, ship impactful work weekly, and define the product experience for our customers.

We're in person 5 days a week in our new NYC HQ in Flatiron, where we collaborate tightly, iterate quickly, and build an environment that's both high-energy and deeply focused. We believe the best work, and the fastest learnings, happen together.

We care about your growth. You’ll get direct mentorship, stretch into new skills across engineering, design, and product, and be part of a team that wants you to succeed. This is a place to accelerate your career, build your craft, and make outsized impact.
