Job Description:

You deserve a personal BetterUp Coach, the most curious teammates on the planet, and a mission that pulls you out of bed every morning. At BetterUp, we pair world-class coaching with Generative AI to help millions live with clarity and purpose. Ready to engineer the models that make that magic feel personal? What you’ll do • Prototype, fine-tune, and evaluate LLM-powered features—from conversational insights to practice-moment nudges—using Python and Jupyter notebooks. • Own the production lifecycle: data prep, experiment design, offline/online evaluation, and weekly pushes to prod alongside a tight squad of ML/Backend/Full Stack Engineers. • Collaborate daily with Product, Coaching Science, and Learning Design to turn behavior-change research into delightful user moments. • Contribute to technical design by shaping model architectures, retrieval strategies, and safety guards—while staying hands-on in code. • Measure what matters: define success metrics, implement A/B tests, and iterate quickly on real coach feedback. • Ship end-to-end improvements to products like FocusFrame, our AI copilot that helps coaches deliver higher-impact sessions in real time. We are a hybrid company with a focus on in-person collaboration when necessary. Employees are expected to be available to work from one of our office hubs at least two days per week, or eight days per month. Our US hub locations include: Austin, TX; Chicago, IL; New York City, NY; San Francisco, CA; and the Washington, DC metro area. If this is a role based in Europe, our Europe hub locations are London, UK and Amsterdam, NL. Please ensure you can realistically commit to this structure before applying. What You’ll Bring Core • 4 years building and shipping ML systems in production, with at least 6–12 months hands-on with LLM fine-tuning, prompt engineering, or RAG pipelines. • Fluency in Python for AI development and comfort working in Jupyter/IPython. • Solid understanding of modern ML tooling (e.g., PyTorch, TensorFlow, or JAX) and containerized/cloud deployment basics. • Clear, approachable communication with both technical peers and non-technical partners. • Bias toward action, curiosity, and comfort navigating ambiguity in a fast-moving startup environment. Bonus (nice-to-have, not required) • Prior experience in coaching, learning-science, ed-tech, or behavior-change domains. • Exposure to RLHF, preference tuning, or multimodal models. Not sure you hit every bullet? We value growth mindsets—please apply anyway. AI at BetterUp Our team thrives at the intersection of human expertise and AI capability.

Benefits : At BetterUp, we are committed to living out our mission every day and that starts with providing benefits that allow our employees to care for themselves, support their families, and give back to their community. • Access to BetterUp coaching; one for you and one for a friend or family member • A competitive compensation plan with opportunity for advancement • Medical, dental, and vision insurance • Flexible paid time off • Per year: o All federal/statutory holidays observed o 4 BetterUp Inner Workdays o 5 Volunteer Days to give back o Learning and Development stipend o Company wide Summer & Winter breaks • Year-round charitable contribution of your choice on behalf of BetterUp • 401(k) self contribution
