The Role:
- We are looking for an AI-native Senior Product Engineer who combines product taste, user empathy, strong technical judgment, and hands-on engineering ability.
- This is a combination of an engineering role and a Product Manager role, enabled by AI.
- You should be able to talk to users, identify high-leverage problems, design thoughtful solutions, write requirements, build prototypes, ship production features, and use AI tools to move dramatically faster.
- You should be comfortable reading and writing code, especially in React and Node.
- Your real superpower is shipping insanely fast using AI for research, design, implementation, testing, debugging, QA, and iteration.
- You will own major parts of the Kickoff product experience and help define how AI transforms fitness, wellness, and preventative health.
What You Will Do:
- Use AI and agentic harnesses in every part of your work, allowing you to ship faster and expanding the product surface where you can make an impact.
- Own product areas end-to-end: discovery, user research, prioritization, specs, design direction, implementation, QA, launch, and measurement.
- Build delightful consumer and coach-facing product experiences across web and mobile surfaces.
- Work directly with coaches and clients to understand pain points, workflows, and opportunities.
- Develop AI-powered features that help coaches deliver better, more personalized guidance.
- Improve our ability to personalize workouts, nutrition recommendations, habits, sleep interventions, and behavior-change support.
- Build systems that identify meaningful patterns in client data, including workouts, meal logs, messages, habits, and wearable data.
- Define clear success metrics, test plans, and evaluation frameworks for AI-powered product features.
- Contribute to a high-agency, in-person NYC team obsessed with helping people get healthier.
Example Problems You Might Work On:
- How can we help a coach instantly understand what happened with a client in the last day and what to do next?
- How can we generate workout recommendations that adapt over time based on adherence, injuries, preferences, goals, and progress?
- How can AI help coaches give better meal-log feedback that actually changes behavior?
- How can we detect early signs that a client is losing motivation and help the coach intervene?
- How can wearable data inform better guidance around sleep, recovery, workouts, and mood?
What We Are Looking For:
- You are an AI-native builder, building incredible products that users love at high speed using AI and agentic tools every day.
- You also have strong full-stack engineering skills, especially with React and Node.
- You have experience improving LLM outputs over time with evals and fine tuning.
- You can move from user interview to prototype to production-quality implementation quickly.
- You are excited by fitness, wellness, nutrition, behavior change, preventive health, and healthcare.
- You are motivated by helping people improve their lives in measurable ways.
- You are high-agency, low-ego, and comfortable operating in a fast-moving startup.
- You are excited to work in person with a tight-knit team in NYC.
Bonus Points:
- You have built health, wellness, fitness, or other relevant consumer products with excellent UX.
- You have strong design instincts or experience using AI tools for wireframes, prototypes, and visual exploration.
- You are active in the NYC tech/startup community.
- You have been a founder or early startup employee.
- Note: although this posting is open to applicants across the US, this is a hybrid role based in New York, NY (524 Broadway) — not fully remote. We support relocation costs for candidates moving from outside the area.
