Trace Labs is an early-stage startup building data infrastructure for physical AI, specifically focused on transforming real-world human work into structured training datasets for robotics and foundation models. They are hiring experienced engineers (Full Stack, Computer Vision) for a fully remote, lean team with founders who have had a successful exit. The company aims to solve the data bottleneck for embodied AI.
What they want, where you stand, and the exact résumé edits to qualify.
Biggest lever: Demonstrating specific experience in building or contributing to data pipelines for robotics/physical AI, perhaps by leveraging their AI engineering and web skills.
A starter prompt for Claude Code, what you'll need, and how to reach them.
You are an expert full-stack developer. Your task is to build a minimal viable product (MVP) for a web-based data annotation platform specifically for embodied AI, focusing on video object tracking and event labeling. The core functionality should allow a user to upload a short video, define bounding boxes for objects, and label specific events within the video timeline. Use Next.js 16 App Router with React 19, Tailwind v4 for styling, and store annotations in a Neon Postgres database. For the video player, integrate a lightweight, client-side library like React Player. Here's the MVP scope: 1. **Video Upload/Management**: A simple interface to upload MP4 videos. Store video metadata (filename, duration) in Postgres. 2. **Video Player Component**: Display the uploaded video with basic playback controls (play, pause, seek). 3. **Object Tracking (Bounding Boxes)**: Implement functionality to draw and resize bounding boxes on video frames. Users should be able to advance frames and adjust bounding boxes per frame, with the system interpolating between keyframes. Each bounding box should have an associated label (e.g., 'robot arm', 'object'). Store bounding box coordinates, labels, and frame numbers in Postgres. 4. **Event Labeling**: Allow users to mark specific time ranges (start/end timestamps) in the video with descriptive event labels (e.g., 'grasp action', 'collision', 'successful pick'). Store event labels and time ranges in Postgres. 5. **Data Export**: A simple button to export all annotations for a video in a structured JSON format (e.g., similar to COCO format, but for video). Prioritize a smooth annotation UX. Focus on the front-end interaction and the Postgres schema for efficient storage and retrieval of annotations. Provide a clear `README.md` for local setup and a `/docs/api.md` explaining the annotation data structure.
Trace Labs | Remote (USA) | Full Time | https://tracelabs.ai/ Want to join a lean, ambitious, and fast growing startup? Trace is building the data infrastructure for physical AI. Robotics and embodied AI are bottlenecked by real-world data. We’re building the platform that turns real-world human work into structured training datasets for robotics and foundation model labs. We’re hiring engineers to help build the core product from end to end. Small, senior team. Fully remote. Experienced founders with a successful exit. Clear communicators. High trust, high bar. Open Roles - Full Stack Engineer: https://jobs.ashbyhq.com/tracelabs/963005ce-f4f1-4d54-957d-1... - Computer Vision Engineer: https://jobs.ashbyhq.com/tracelabs/774fbd47-20ce-4665-9bdb-5... What We Offer - Autonomy, impact, and ownership. As an early employee you’ll shape the product direction and company values. - Competitive salary and significant equity in a fast growing, early stage startup. - Remote employment - work where you want, when you want. - Generous vacation policy - take time whenever you need to recharge. Building a lasting company is a marathon, not a sprint.
Build a small project that takes real-world (e.g., simulated robot sensor) data, processes it via web services/AI, and outputs a structured training-like dataset. Focus on the data ingestion, transformation, and API design. (4-6 weeks to ship a demo/MVP).

“I'm a solo operator with deep experience in rapid prototyping and building composable software products, and I'm very interested in Trace Labs' mission. I've built a working MVP of a video annotation tool for embodied AI, showcasing object tracking and event labeling, which I believe aligns well with your data infrastructure needs. Happy to share a demo and discuss how my agile approach and AI-assisted development could accelerate your core product development.”
