About the Role

Are you an entrepreneurial software engineer eager to build impactful, mission-driven, consumer-facing AI products? Join Outgoing, a dynamic AI startup based in Paris, founded by seasoned entrepreneurs. We believe the best moments happen offline. In a world increasingly tethered to screens, we're building the antidote: an AI-powered concierge that helps people get off their screens to discover, plan, and enjoy real-world activities.

The Opportunity

As an early team member, you'll directly shape Outgoing's core product. This is hands-on, applied AI, not theoretical research: We need engineers fluent in implementing and experimenting with the fast-evolving open-source LLM space, ready to operate at startup velocity, on a consumer-facing product.

What You'll Do

You’ll lead designing, developing, and deploying the core AI systems for Outgoing's personalized recommendations engine. Key responsibilities include:

• Implementing & Optimizing LLM-Powered Features: Integrate and fine-tune open-source Large Language Models (LLMs) to enhance natural language understanding, content generation, and conversational interfaces.
• Developing Advanced Ranking & Recommendation Algorithms: Design and implement generative and traditional ML to deliver highly personalized and contextually relevant activity suggestions.
• Owning End-to-End Development of Scalable Platforms: Take full ownership of key features from concept to deployment, developing robust systems that ensure high performance, scalability, and reliability in a fast-paced environment.
• Driving Technical Architecture & Tooling Decisions: Contribute significantly to strategic technical decisions, including system architecture, technology stack, and platform evolution.

What We're Looking For

• 5+ years of hands-on engineering experience scaling complex, user-facing products
• Proven hands-on experience applying Large Language Models (LLMs) in production environments, ideally including fine-tuning and quantizing open-weight models (e.g. Gemma, Llama, Qwen)
• Strong familiarity with ranking algorithms and recommendation systems, with experience in their design, implementation, and optimization, similar to roles at companies like Perplexity AI or Google's YouTube
• Proficiency with Python (including Pydantic), modern backend frameworks like FastAPI, Google Cloud Platform (GCP), and relational, NoSQL, vector, and graph databases.
• Bonus: Experience with Flutter, Node.js, Rust

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
• 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.
