Registered Dietitian / Nutrition Lead — Redefine Fitness (Stony Brook & Mount Sinai, Long Island)

20 hours per week GUARANTEED from day one. $50–52/hour — roughly 35% above the Long Island RD average. A defined path to a full-time salaried Nutrition Lead role at $90,000/year plus full benefits.

Redefine Fitness is a premium 1-on-1 personal training and wellness brand built on one principle: fitness is medicine. Nutrition is becoming a core pillar of our business, and we're hiring the Registered Dietitian who will lead it.

This is NOT cold selling and NOT lead generation. You'll work a warm pipeline: our existing personal training clients and trial nutrition clients, in-studio, face to face.

What you get:

- 20 hours/week guaranteed — stable, scheduled hours, not "as needed"

- $50–52/hr to start, by experience

- Growth bonus: 25% of the first payment on every new nutrition membership you bring on from our warm client base

- Quarterly performance bonus

- Defined full-time conversion: when the nutrition book reaches the full-time threshold, you convert to salaried Nutrition Lead at $90,000/year with health, dental, vision, and PTO — and you own the department and its future hires

- Part-time benefits now: 401(k), AFLAC, free gym membership, employee discount, flexible scheduling

What you'll do:

- Deliver 1-on-1 nutrition coaching: assessments, personalized macro/meal planning, weekly and bi-weekly check-ins, InBody/DEXA review, behavior-change coaching

- Convert trial nutrition clients from our existing training base into ongoing members

- Host a monthly nutrition webinar for our client community

- Help build client-tracking and retention systems as the department grows

- Split the week between our Stony Brook and Mount Sinai studios (about 15 minutes apart), including some evenings

What you need:

- Registered Dietitian (RD/RDN, CDR-registered); NY Certified Dietitian-Nutritionist (CDN) or eligible within 90 days

- 2+ years of counseling/coaching experience (private practice, outpatient, sports, or metabolic)

- Comfort with body-composition tools (InBody/DEXA) and behavior-change coaching

- A growth mindset — you want to build a book and a department, and be paid for what you build

Preferred: CSSD, functional/integrative, or longevity focus.

Redefine Fitness is an equal opportunity employer. Employment is at-will.
