➔ Description de la mission

Are you an entrepreneurial engineer with experience building apps in a fast-paced environment? Are you excited to apply those skills on something with positive benefits to society: using technology to get people off their screens? Outgoing is looking for a full-stack engineer, comfortable across the database, backend, and mobile app layers, ready to operate at startup velocity, on a cool, consumer-facing product that's good for the world.

What You'll Do

As our Full-Stack Engineer, you'll lead designing, developing, and deploying features across the board, from our crawler to our ranking and retrieval systems to our generative UI. Key opportunities and responsibilities include:

  • Own End-to-End Development of Features: We're looking for someone independent, who can take full ownership of key features from concept to deployment, developing robust systems in a fast-paced environment. We value experimentation over perfection -- this isn't a theoretical role, we're trying to quickly deliver value to our users.

  • Scale Web Crawler and Ingestion Pipeline: Leverage LLMs, parsers, and distributed systems architecture to ingest, enrich, and store activity data from a wide variety of online and offline sources.

  • Optimize Indexing and Retrieval: Help evolve and scale our content index to support a global catalog of unique, real-world activities, across a wide variety of user query intents. Implement new information retrieval, ranking, and recommendation algorithms in collaboration with our AI/ML leads.

  • Drive Technical Architecture & Tooling Decisions: We're an early-stage startup so there's loads of opportunity for contributing and owning strategic technical decisions like system architecture, technology stack, and platform evolution.


➔ Profil recherché

What We're Looking For

  • 3+ years of hands-on engineering experience working on multiple layers of complex, user-facing products

  • Experienced with Python (including Pydantic), PostgreSQL, Flutter/Dart, and React/Next, with bonus points for familiarity with FastAPI, Google Cloud Platform, vector & graph databases, and open-source information retrieval frameworks

Our Culture

We’re a team that values collaboration, proactive problem solving, and strong empathy. You’ll thrive here if you

  • Are a proactive builder: You don’t wait for perfect specifications: you prototype, iterate, and drive solutions forward

  • Embrace learning & teaching: This moment in technology is moving incredibly fast; our team wins when we stay on top of the latest trends and share learnings with each other

  • Communicate with clarity: Particularly as a remote team, articulating complex technical and product concepts simply is paramount. We favor async design discussions when possible.

  • Are obsessed with our users: Building a consumer product is about putting our users first above technology; we’re using tech to build something that truly delights

Work Setup

We are a remote-first team operating in the European time zone (HQ in Paris) and communicating in English. This is a full-time role with competitive salary, benefits and equity.

Whom You'll Work With

We're seasoned entrepreneurs and engineers from some of the largest consumer technology companies, so you'll have a chance to collaborate and learn with an experienced, technically-deep, mission-driven team, including:

Mark, Rob, Juan, JF, Ludo, Matt, Naveen, and more.

Does the idea of building AI that brings people together excite you? We’d love to hear from you!
