Frontend Engineer

About The Team

Adaptive ML is a frontier AI startup building a Reinforcement Learning Operations (RLOps) platform that enables enterprises to specialize and deploy LLMs into production with measurable impact. We provide the core infrastructure to tune, evaluate, and serve specialized models at scale — pioneering task-specific LLM development and running production-ready workflows that serve millions of requests while optimizing for cost and performance across distributed systems.

Our tightly-knit team was previously involved in the creation of state-of-the-art open-access large language models. We raised a $20M seed led by Index Ventures and ICONIQ in early 2024, and we are already live in production with customers including Manulife, AT&T, and Deloitte across travel and financial services — with much more to be announced soon.

About The Role

As a Frontend Engineer on our Product Team, you will help transform our technology into exceptional products. Our products allow companies to build more singular generative AI experiences with deeper personalization through reinforcement learning. We prioritize product quality, with a bias for clarity, responsiveness, and robustness — achieved through meticulous attention to detail across every layer of the user experience.

You will join a frontend team of two, collaborating closely with Backend Engineers and Technical Staff to bring new features to life. Challenges may include building interfaces that surface complex, real-time AI workloads (e.g., streaming inference, live training feedback) in an intuitive and performant way, and creating scalable UI abstractions that hold up as our product grows. We are looking for self-driven, ambitious individuals who care deeply about craft and want to contribute to a highly technical product that prioritizes robustness, accessibility, and responsiveness.

This is an in-person role based out of our Paris Office.

Your responsibilities

• Design, iterate, and implement the frontend of our products;
• Develop high-quality TypeScript/React software, with elevated standards of performance and user experience;
• Build and maintain a cohesive design system and component library that scales with the product;
• Construct systematic processes for frontend development, helping remove unknowns in our strategy;
• Contribute to our product roadmap, bridging the needs of our Commercial Team with the latest capabilities from our Technical Team;
• Report clearly on your work to a distributed collaborative team, with a bias for asynchronous written communication.
  
  

Your (ideal) background

• Significant experience in frontend or frontend leaning full-stack software development;
• Strong engineering skills with a focus on performance, accessibility, and UI robustness;
• Proficiency in modern frontend tooling — React, TypeScript, and the broader ecosystem;
• A track record of shipping ambitious, polished products under tight deadlines;
• A deep concern for user experience, with an eye for detail at the intersection of design and engineering;
• Passionate about the future of generative AI, and eager to build foundational technology to help machines deliver more singular experiences.
• Comfortable leveraging AI-assisted programming tools (e.g. Cursor, Claude Code, or similar) as part of an established personal workflow to ship faster and with greater confidence.
