Senior Frontend Engineer

At Weave, our mission is to evolve how therapeutic knowledge is captured, transformed, and communicated throughout drug development. We do this by equipping human experts with AI instruments to enable drugs to be brought to patients as rapidly, safely, and inexpensively as possible.

The Weave Platform streamlines regulatory workflows from start to finish by intelligently, creatively, and effectively infusing every step with AI. Together with our customers, Weave is designing and building the AI workbench for the entire therapeutic lifecycle.

We’re building a collaborative document platform and we need a Frontend Engineer who obsesses over craft, usability, and shipping things that genuinely work for customers.

You’ll thrive here if you move fluidly from problem discovery to prototype to production, making smart tradeoffs along the way. We value simple, well‑tested, and reliable solutions over hype‑driven complexity. If you love turning ambiguous customer problems into polished, performant interfaces, keep reading.

• Customer‑centric problem solving. Deeply understand how customers use our product, then translate that understanding into intuitive, elegant frontend experiences.
• Collaborative product development. Partner closely with Product and Design to shape what gets built. You’ll have a seat at the table from ideation through delivery.
• Real‑time, collaborative editing. Architect and build a rich document editor with multiplayer collaboration features (think CRDTs, presence indicators, conflict resolution) that feels seamless at scale.
• High‑quality frontend code. Write performant, well‑tested Type Script and React that your teammates (and your future self) will thank you for. We value readability, maintainability, and thoughtful abstractions.
• Technical direction. Drive software design decisions on your projects, managing conceptual and technical complexity so the codebase stays healthy as the product grows.
• Continuous delivery of value. Balance speed with quality. Ship iteratively, measure impact, and refine based on real‑world usage.

• 5+ years of production experience building modern web applications with React, Type Script, and the broader frontend ecosystem (state management, bundlers, testing frameworks, design systems).
• AI‑augmented engineering expertise. You’re a skilled engineer first and you use AI‑powered tools (e.g., Cursor, Claude) to meaningfully accelerate your workflow. You know how to leverage AI for code generation, exploration, debugging, and documentation while applying the deep technical judgment needed to evaluate, refine, and take full ownership of everything you ship. We’re looking for engineers who treat AI as a force multiplier for their craft, not a substitute for it.
• Startup experience. You’ve worked at an early‑stage, product‑focused company (ideally
