Let's face it: if you're going to build the future of human transformation, you deserve more than a paycheck. You deserve a personal Better Up Coach, the most curious teammates on the planet, and a mission that pulls you out of bed every morning. At Better Up, 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 Focus Frame, 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;
New York City, NY;
San Francisco, CA; and the Arlington, VA metro area. 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, Tensor Flow, 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.
