About Aeternitas

Aeternitas is a physician-led precision health and preventive medicine practice focused on longevity and healthspan optimization. Our mission is to reduce long-term risk of all-cause mortality by helping patients understand their individualized risk profile and act on it through data-driven, personalized care.

We take a prevention-first approach that looks beyond disease treatment alone. Using advanced diagnostics, clinical judgment, and longitudinal follow-up, we evaluate health across multiple domains — including cardiovascular, metabolic, musculoskeletal, cognitive, and emotional health — and develop tailored strategies to support long-term resilience and function. Exercise, nutrition, and behavioral support are key health optimization levers within a broader, integrated care model.

Care at Aeternitas is delivered by a collaborative, multidisciplinary team — including a physician, dietitian, exercise physiologist, and licensed mental health therapist — working together to create individualized, precision-focused plans that evolve over time. We emphasize scientific rigor, thoughtful execution, and a high standard of patient experience, applying precision medicine upstream of chronic disease to support durable health across the lifespan.

Aeternitas is in an early growth phase. Patient volume will ramp gradually through 2026, with expanding responsibilities and continuity as the practice grows. Early hires will have the opportunity to help shape standards, workflows, and the long-term delivery of precision nutrition care within the practice.

About the Role

As a Clinical Dietitian at Aeternitas, you will play a central role in translating complex diagnostic and lifestyle data into clear, individualized nutrition strategies designed to support metabolic health, cardiometabolic risk reduction, and long-term resilience.

This role sits at the intersection of nutritional biochemistry, clinical reasoning, and patient behavior change. You will integrate labs, body composition data, medical history, and—when applicable—continuous glucose monitoring to design nutrition plans that are practical, evidence-based, and sustainable.

You will also serve as a longitudinal partner for patients, helping them implement and adapt nutrition strategies over time while collaborating closely with the physician and care team. As an early team member, you will help shape nutrition frameworks, follow-up cadence, and care delivery systems—while maintaining a calm, professional, and premium patient experience. This position is well-suited to a clinician seeking the opportunity to share in the practice’s success as an early contributor.

This role is ideal for someone who is excited by the longevity space, prioritizes evidence and mechanism, and wants to apply nutrition science to midlife and aging populations—not rigid dietary ideologies or one-size-fits-all approaches.

What You Will Do & How You Will Spend Your Time

Design individualized nutrition strategies informed by caloric balance, macronutrient distribution, meal timing, and metabolic health markers.

Integrate physician guidance and medical constraints into nutrition planning.

Longitudinal Nutrition Care & Follow-Up (35%)

Conduct scheduled follow-up visits based on membership tier to assess adherence, barriers, and progress.

Adjust nutrition strategies over time using objective data, patient feedback, and evolving clinical priorities.

Serve as an accountability partner while appropriately challenging assumptions and behaviors that conflict with patient goals.

Diagnostics & Evaluation Support (10%)

Participate in initial evaluation days to meet patients, clarify nutrition history, and establish rapport.

Coordinate closely with the physician and exercise physiologist to align nutrition priorities within the broader care plan.

Operational Excellence & Program Development (20%)

Contribute to the development of standardized yet adaptable approaches to nutrition care across patient tiers.

Maintain accurate, timely documentation in accordance with clinic standards.

Experience & Skills

Required

Registered Dietitian (RD/RDN) credential

Prior experience providing nutrition counseling to adults in a clinical, medical, or outcomes-focused setting - New graduates are not a fit for this role

Strong foundation in nutritional biochemistry, macronutrients, caloric balance, and metabolic health

Excellent verbal and written communication skills

Preferred

Experience working with metabolic dysfunction, insulin resistance, dyslipidemia, or weight management

Experience using or interpreting continuous glucose monitoring (CGM) data

Comfort collaborating with physicians on nutrition strategy alongside pharmacotherapy

Experience working with midlife or older adult populations

Who Thrives in This Role

We’re looking for someone who is motivated by longevity, healthspan, and prevention-focused care, and who sees nutrition as a powerful—but not dogmatic—lever within a broader precision health model.

You think in terms of long-term risk reduction, not short-term dietary wins. You are comfortable working with complex data, uncertainty, and individualized decision-making, and you understand that guidelines inform care—but do not replace clinical judgment.

You communicate clearly, calmly, and confidently with patients. You are able to explain nutrition concepts in an accessible way, challenge assumptions respectfully, and support behavior change without rigidity or judgment.

You value evidence, mechanism, and measurement over dietary ideologies. You are intellectually curious, open to updating your thinking as new data emerges, and committed to continuous learning.

You are adaptable and comfortable in a growing practice. You enjoy helping build systems, refine workflows, and improve processes—not just executing what already exists. You take ownership of your work and are energized by the opportunity to contribute meaningfully as the practice evolves.
