About Flatfile

Flatfile is revolutionizing enterprise data handling through AI automation. We're building an AI-native data mapping, cleaning, and transformation platform that tackles the most stubborn data problems for the world's largest organizations.

What is a "Developer Experience Lead" at Flatfile?

The future isn’t fixed. It’s built. We realize the future at the rate that builders are able to build. We believe that the future of software development lies in abstracting away the tedious and repetitive tasks developers waste time on, while creating reusable components that act as a force multiplier for developers and projects. The result is not just productivity, but good software by default. And that’s a mission worth striving for.

If you agree, we have an extraordinary opportunity to join our mission.

Flatfile provides AI-powered tools for migrating data to thousands of companies and developers, from startups to Fortune 500 companies. With growing traction in the enterprise sector, Flatfile has already achieved strong product-market fit and is looking to take it to the next level with a world-class developer experience.

Skills you’ll need to bring

A drive to make developers’ lives better

You have a strong interest in keeping engineers in their flow state through better tooling. You like to think critically about the workflows engineers use in their day-to-day work, finding bottlenecks and thinking outside of the box to find ways to pave a better golden path for engineers to follow.

A focus on user experience

You bring care and craft to the user experience you build into your products. Your work emphasizes simplicity, supportability, and ease-of-use, and you communicate clearly with other teams and engineers to get feedback on where we can make building with Flatfile the most elegant builder experience.

Multitasker and present

You like interruptions, especially if they block engineers. You switch fluidly between your project work and daily developer experience challenges.

Interest in learning how things work

You love to learn how the tools you use work at a fundamental level. You get excited at the idea of digging into third-party source code to understand how they work and find new ways to use them.

Pragmatic and business-oriented 

You care about business impact and prioritize projects accordingly. You don't just go after cool stuff—you understand the balance between craft, speed, and the bottom line. To you, technologies and programming languages are about tradeoffs. You may be opinionated, but you're not ideological and can learn new technologies as you go.

Collaborative

You partner with customers, developers, and our success team to understand their needs, provide technical guidance, and showcase how our platform solves real-world challenges in building data exchange systems into their applications and workflows.

Feedback machine

You collaborate closely with product, engineering, and marketing teams to relay community insights, advocate for developer needs, and ensure our platform evolves to meet user expectations.

Our tech stack

In this role, you’ll primarily work with TypeScript/JavaScript, Node.js, and Flatfile’s APIs and SDKs. You’ll collaborate with teams working in Go, Python, and React, and interface with tools such as OpenAPI, GitHub Actions, LLM inference engines, and cloud platforms like AWS or GCP.
