Dust

ABOUT DUST Work is being rewritten, and the people holding the pen are the ones who actually run it. With enterprise-grade governance, flexible model choice, and a collaborative interface for humans and agents to work together, Dust empowers AI Operators at the world’s fastest-moving companies to rewire how work gets done. With 70%+ weekly active users, people stick with Dust as much as they do with Slack and Notion. We don't get piloted and shelved. We land once, and spread. We're at an exciting stage of our journey, and growing fast. We're serving great customers like Datadog, 1Password, Cursor, Clay, Vanta and Persona, and aim to x5 our growth by the end of 2026. Dust is backed by Sequoia with a determined team of optimists (coming from Stripe, OpenAI, and Stanford) who like to focus on users, ship fast, and don't take themselves too seriously while doing so. The Generalist named us among the Future 50. TL;DR We are looking for an experienced frontend engineer who feels comfortable working on backend tasks as needed. In this role, you will collaborate closely with our product designer team, contributing ideas to shape the user experience while implementing features in our React-based frontend. On the backend side, you’ll contribute to REST API work and infrastructure improvements and ensure a smooth developer experience across our codebase. OUR CULTURE * Product-First: Unlike others focused on building foundation models, we're laser-focused on creating delightful product experiences with existing LLMs. Think “No GPUs before PMF”. * Small, High-Impact Team: Join a team of alumni from Stripe, Front, OpenAI, and other top tech companies. We're intentionally keeping our team small and mighty – every individual has massive scope and impact. * Transparency & Collaboration: Our repository is open source, and we leverage serendipity between team members. We believe the best ideas emerge when the team shares information and insights openly. * Proactive Problem-Solving: If you see something broken, fix it—without waiting for permission. We don't wait for solutions - we create them. * Ship to Learn: We move fast and learn from real user feedback. * Intellectual Humility: We value strong convictions balanced with open-mindedness. Team members confidently advocate for their ideas while remaining receptive to new perspectives and evidence that might change their minds. If new data emerges, we adapt quickly. WHAT YOU’LL DO * Create delightful frontend experiences end-to-end: Design and implement visually engaging interfaces that define how users interact with Dust. * Frame and lead frontend technical projects to completion: Balance performance, accessibility, and maintainability—all with a full-stack perspective in mind. * Collaborate closely with users and product designers: Brainstorm interface solutions, gather feedback, and iterate rapidly to build delightful user experiences. * Build for scale: Architect frontend systems that gracefully handle increasing complexity while preserving simplicity and speed. * Champion best practices: Advocate for code quality, guide our design system’s evolution, and ensure every feature meets high standards of excellence. * Dive into the backend: Use Next.js (Node/TypeScript) to handle REST APIs, data retrieval, and integration tasks. TECH STACK HIGHLIGHTS * Dust for Dust: We use Dust for Coding, debugging, knowledge search (runbooks, codebase), incident management, and task automation (i.e., creating issues). * Programming languages: TypeScript, Rust (not a requirement, we’re open to people expert in other programming languages). * Other relevant tools and technologies: * Frontend: React, shadcn * Backend: NextJS, Kubernetes, Terraform/Helm * Database: PostgreSQL, QDrant, Elasticsearch * DevOps: Datadog monitoring, Github actions based CI/CD BENEFITS & COMPENSATION * Competitive compensation: €30K - €150K* base salary * We offer substantial support for relocation, including a stipend up to €10k, finding an apartment in Paris, and supporting you with all residence and work permit-related procedures * Significant equity package in a Sequoia-backed startup * Health insurance for you and your dependents * New MacBook Pro or Linux machine, monitor, keyboard, etc. * Beautiful office in the heart of Paris * Opportunity to travel to the US multiple times a year * Regular team events and offsite DUST ENGINEERING SALARY GRID Regarding compensation culture, we're going to lean towards Netflix's early philosophy: we are happy to review levels and compensation as early and as often as it makes sense to do so, not when the calendar says so. Regarding expectations associated with levels, we're including a very broad definition of each level below. When attributing a level at hiring, the expectation is for you to perform comfortably at this level within your first year. We'll set up catch-up times throughout that first year to keep track of your progress and communicate clearly whether you're matching these expectations. - Level I: Limited prior experience, learning the ropes - Level II: Level I + Autonomy - Level III: Level II + Rigorous dependability - Level IV: Level III + Excellence - Level V: Level IV + Leadership - Level VI: Level V + Impact on company trajectory *We can go higher for outstanding profiles. LOCATION We're prioritizing building our team with an in-person culture at our offices in Paris, San Francisco, and New York because we value the magic that happens when talented people work closely together. We have an office-first culture. Some of the best things about building at Dust are the energy, the fast decisions, and the unexpected conversations that unlock a hard problem, which happen because we are in the same room. Being together is not a formality, it is how we do our best work, and it is something we actively protect. That said, we hire people with strong judgement and we extend that trust to how they manage their time. When working from home makes more sense for what you need to get done that day, we trust you to make that call. WHY DUST The models are powerful enough. What's missing is the product layer where AI meets how companies actually work. That's what we're building: the infrastructure that lets any team turn scattered knowledge and tools into coordinated execution with agents they build, own, and run themselves. We use Dust ourselves every day. We get to shape how humans and agents collaborate while solving our own problems with the product we ship. That loop is rare, and it's why we move fast. If you're excited about defining a new category and want to join a determined team of optimists who focus on users, ship fast, and don't take themselves too seriously, we'd love to talk. Even if you don't check every box in our requirements, we encourage you to apply. We value diverse perspectives and backgrounds, and we're more interested in your potential and passion than a perfect match to our checklist. Learn how we think and work. * Our product constitution, a story about our mission * Agents at work - Latent Space, podcast with our cofounder, Stanislas Polu, 2024 * LLMs reasoning and agentic capabilities over time - dotAI, podcast with our cofounder, Stanislas Polu, 2024

PROFILE * Strong programming skills in iOS (Swift/SwiftUI), with 4+ years of experience. * Product mindset: you obsess over user needs, think in metrics, and make data-driven decisions. * You can both hack together a quick prototype and build production-grade systems. * Strong UI/UX design skills: you can go from wireframe to polished, high-fidelity screens. Proficiency in Figma is required. * You're hyper-analytical: you test your hypotheses rigorously and let data guide your priorities. * You're passionate about B2C mobile apps and have a track record of shipping meaningful features or products. * You're highly driven, autonomous, and results-oriented. * You're fluent in English (French is a plus). BENEFITS * Competitive salary upon experience * Swile Lunch voucher * Gymlib (100% borne by Voodoo) * Premium healthcare coverage SideCare, for your family 100% borne by Voodoo * Wellness activities in our Paris office * €1,000 annual budget for attending tech conferences and professional events
