Product Engineer (Front End) - Remote

Overview

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.

In Short

• 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 technologies.
• Implement complex React components: virtualized tables/lists, drag‑and‑drop editors, real‑time collaborative cursors/selections, rich text/data co‑authoring, and more.
• Evolve our real‑time collaborative editing model for experiences with low‑latency, conflict‑aware UX.
• Profile and improve app performance end‑to‑end: bundle strategy, render paths, memoization, concurrent features, scheduling, and network usage.
• Shape new UI patterns for autonomous agents in work‑centric interfaces: intent visualization, agent transparency, corrective control, and multi‑agent collaboration.
• Establish state‑of‑the‑art cross‑browser and cross‑device testing so our experiences “just work” every time.
• Make clear trade‑offs balancing user experience, delivery speed, and business impact—and influence these decisions across the org.

Requirements

• Significant experience shipping production web apps with meaningful contributions to design, architecture, and performance.
• Deep expertise in frontend technologies: TypeScript, JavaScript, React, and CSS (modern layout, animations, variables, architecture).
• Hands‑on experience with complex UI problems: virtualization, drag‑and‑drop, real‑time collaboration, rich editors, canvas/WebGL, or data‑dense UIs.
• Proven ability to optimize at the system level: asset pipelines, code‑splitting, hydration strategies, caching, and profiling.
• End‑to‑end product development: ideation, product spec, prototyping, design partnership, implementation, and iteration.
• Track record of raising the bar for technical standards, performance, reliability, and operational excellence.
• High autonomy and accountability; can do large amounts of meaningful work quickly with little oversight.

Benefits

• Taste: You sweat the details—type, motion, density, affordances, empty states—and you know when to cut scope to protect quality.
• Velocity: You operate at an unreasonable pace without leaving a mess. You default to simple designs that scale.
• Judgment: You pick the right tools, patterns, and abstractions—and resist the wrong ones.
• Systems thinking: You design components and data flows that compose; you remove complexity, not just add features.
• Ownership: You lead projects from fuzzy idea → prototype → production → polish → impact.
• Experience: You have a proven record of exceptional achievements and impact.
• Adaptability: You have a willingness to work hard, move fast and grow quickly in a rapidly changing environment.
• Camaraderie: You have a humble attitude, an eagerness to help your colleagues, and a desire to do whatever it takes to make the team succeed.
• Smithing: Build tools to accelerate your own (and your teammates') workflows, but only when off-the-shelf solutions won't do.
