Product Engineer - Agent Platform

About Flatfile

Flatfile is revolutionizing how enterprises handle their most stubborn data problems. We’re building an AI-native data mapping, cleaning, and transformation platform that enables the world’s largest organizations to put messy, complex data to work fast.

Think of Flatfile as the missing operating system for enterprise data.

Start with a spreadsheet, a database, or an API, describe the outcome you need, and Flatfile goes to work: mapping columns, normalizing values, cleaning formats, enriching records, transforming structures, and preparing data for real business use.

Why we’re hiring for this role

We’ve made huge strides with AI features like automated data mapping and transformation, but we’re only scratching the surface of what’s possible.

We need engineers who can bridge the gap between powerful AI models and production-ready features that solve real customer problems. Flatfile builds resilient systems that tackle the toughest challenges in data handling: scale, reliability, messy inputs, distributed workflows, and more.

Flatfile is a small, talent-dense team of world-class builders, former founders, and leaders from companies like Google, Uber, Shopify, and Twitter.

If you’re excited to solve some of the hardest problems in data and AI, and to build products that change how the enterprise world works with data, we’d love to have you join us.

This role reports to: Jon Bell, VP of Product & Engineering

In this role you will:

• Drive full-stack feature development from conception to deployment, taking ownership of key product initiatives

• Ship a lot of product and talk directly to users

• Collaborate on design and implementation of user-facing features that improve user experience

• Build robust, scalable, and performant web applications using modern frontend and backend technologies

• Identify opportunities for optimization and enhancement in existing systems

• Contribute to architectural decisions that shape the future of our product

• Set the industry standard for the UX of agent products

• Optimize prompts, fine-tune model behavior, and evaluate performance

You will thrive in this role if you have:

• A proven record of exceptional achievements and impact

• Willingness to work hard, move fast and grow quickly in a rapidly changing environment

• An exceptional ability to learn

• Solid full-stack foundation: from building React components to developing APIs to integrating with third-party services

• Strong proficiency with TypeScript, React, and modern frontend development practices

• Experience working directly on user-facing products and understanding user needs

• Strong problem-solving skills and attention to detail

• Excellent communication skills and ability to work cross-functionally

• Have a humble attitude, an eagerness to help your colleagues, and a desire to do whatever it takes to make the team succeed

• Build tools to accelerate your own (and your teammates') workflows, but only when off-the-shelf solutions won't do

• Experience with Al/LLM integration in applications

Nice to have:

• Background building coding agents, multi-agent systems, or working on productivity tools

• Previous experience at a high-growth startup

• Contributions to open-source projects

• Strong opinions on agent orchestration and designing system prompts

This role may not be a fit if:

• You prefer working exclusively on backend systems without user interaction

• You're uncomfortable with the pace and changing priorities of a startup environment

• You require highly structured requirements and aren't comfortable with ambiguity
