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 exercise physiology within the practice.
About the Role
As an Exercise Physiologist at Aeternitas, you will play a central role in translating physiologic data into actionable, individualized exercise strategies designed to improve long-term health, resilience, and functional longevity.
This role sits at the intersection of diagnostics, clinical reasoning, and patient communication. You will administer and interpret advanced exercise and performance testing, design evidence-based exercise prescriptions, and follow patients longitudinally as they work to improve fitness metrics that meaningfully impact healthspan and mortality risk.
You will also be an early team member in a growing practice. That means helping shape workflows, refine protocols, and contribute to how precision exercise physiology is delivered at scale all while maintaining a calm, professional, and premium patient experience.
This role is ideal for someone who is excited by the longevity space, prioritizes evidence and mechanism, and wants to apply exercise physiology to midlife and aging populationsnot just performance or aesthetics.
Whether part-time or full-time, this role is ideal for a clinician who wants to grow with a mission-driven practice, contribute meaningfully during its early phase, and participate in the financial upside of building something exceptional from the ground up.
What You Will Do & How You Will Spend Your Time
Evaluation & Testing (30%)
- Administer and troubleshoot advanced physiologic and performance testing, including VO max, ensuring accurate setup, calibration, protocol execution, and safety monitoring.
- Conduct and support functional and performance diagnostics such as DEXA, motion analysis, grip strength, and related assessments.
- Clearly explain procedures to patients, maintain a composed testing environment, and monitor for safety concerns or red flags.
- Follow standardized testing protocols and QA checklists to ensure high-quality, reproducible data over time.
Interpretation & Exercise Prescription (30%)
- Interpret physiologic and functional outputs (e.g., VO metrics, thresholds, recovery patterns, movement findings).
- Translate results into clear, individualized exercise prescriptions focused on improving cardiorespiratory fitness, strength, durability, and metabolic health.
- Modify recommendations based on medical history, labs, imaging, contraindications, and physician guidance.
- Collaborate closely with the physician and care team to ensure exercise programming aligns with the broader preventive care plan.
Longitudinal Care & Follow-Up (25%)
- Conduct scheduled follow-up visits to assess progress, adherence, and barriers.
- Adjust exercise strategies over time based on objective data and patient feedback.
- Support continuity across annual reassessments and long-term health planning.
Operational Excellence & Program Development (15%)
- Help refine repeatable protocols, documentation standards, and quality-assurance processes.
- Contribute ideas to improve clinical workflows, patient experience, and care delivery systems.
- Maintain accurate, timely documentation in accordance with clinic standards.
Experience & Skills
Required
- Bachelors degree in Exercise Physiology, Kinesiology, Exercise Science, or related field
- Prior experience working with adult clients or patients in a clinical, performance, or health-focused environment - (New graduates are not a fit for this role.)
- Strong foundation in exercise physiology, cardiometabolic health, and evidence-based programming
- Excellent verbal and written communication skills
Preferred
- Experience conducting metabolic or cardiopulmonary exercise testing (VO max strongly preferred)
- ACSM certification (especially ACSM-CEP) or a clear pathway and intent to obtain
- Experience working with middle-aged or older populations
- Familiarity with body composition and motion analysis tools (training provided)
Who Thrives in This Role
Were looking for someone who is motivated by longevity, healthspan, and prevention-focused care, and who enjoys applying exercise physiology as one important lever within a broader, physician-led precision health model.
You think in terms of long-term risk reduction, not short-term outcomes. You are comfortable working with complex data, uncertainty, and individualized decision-making, and you understand that guidelines inform carebut do not replace clinical judgment.
You communicate clearly, calmly, and confidently with patients. You are able to explain complex concepts in an accessible way, challenge assumptions respectfully, and maintain a composed, professional presence in a high-touch clinical environment.
You value evidence, mechanism, and measurement over trends or ideology. You are intellectually curious, open to updating your thinking as new data emerges, and committed to continuous learning. You take pride in precision, consistency, and follow-through, recognizing that excellence is built through disciplined execution.
You are adaptable and comfortable in a growing practice. You enjoy helping build systems, refine workflows, and improve processesnot just executing what already exists. You take ownership of your work and are energized by the opportunity to contribute meaningfully as the practice evolves.
