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 Senior 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.
What You'll Own- 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 TypeScript 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, TypeScript, 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 <50 people) and know how to operate with autonomy, ambiguity, and limited resources.
- Strong product instincts. You think beyond the component; you consider the user journey, edge cases, accessibility, and how your work connects to business outcomes.
- Bias toward action with high standards. You move quickly without cutting corners. You know when to optimize and when to ship, and you're comfortable making that call.
- Pragmatic, clear thinking. You break down complex problems efficiently, make decisions with conviction, and communicate your reasoning to teammates.
- Collaborative mindset. You give and receive feedback generously, elevate the people around you, and care about the team's success as much as your own.
- Experience building rich text editors or real-time collaborative features (e.g., Slate, ProseMirror, Yjs, Liveblocks).
- Familiarity with a regulated domain or a product where data privacy and security are first-class concerns.
- Contributions to open-source projects or a track record of sharing knowledge with the broader engineering community.
