Alembic · San Francisco
About Us
Alembic is the pioneering Causal AI platform — helping Fortune 100 companies like Nvidia, Delta, and Mars prove what actually drives outcomes, not just what correlates. Backed by a $145M Series B and running one of the world's fastest private supercomputers.
About the Role
We think the performance of the team is the performance of the company, and we're investing in it directly. This is a hands-on training and wellness role embedded with our team onsite — designing and delivering individual programs, coaching people through them, and keeping honest track of what's working. You'll have a defined, consistent schedule and a partner on our side to build the program alongside you.
What You'll Do
Run 1:1 training sessions with team members onsite, on a consistent daily schedule
Design individualized programs across strength, conditioning, mobility, and recovery
Assess new participants and re-assess on a regular cadence, adjusting programs to the data
Keep clean, timely session notes and progress records within your scheduled hours
Coach the habits around the training — sleep, movement, stress, and recovery
Help shape the program's structure and rhythm as participation grows
What Will Help You Succeed
Certified (NASM, ACSM, NSCA, ACE, or equivalent) with current CPR/AED
Real 1:1 coaching experience with a range of ages, abilities, and goals
Comfort working with high-performing, time-constrained professionals — and holding them to the plan
Disciplined about documentation and running on time
Corrective exercise, mobility, or recovery specialization is a plus
The role is right for you if:
You'd rather go deep with a small group of people over time than churn through short-term clients
You like having a say in how a program is built, with support rather than a blank page
Why You Might Be Excited About Alembic
Depth over volume: A consistent roster you get to know, program for, and actually move — not a revolving door of one-off sessions.
A company that means it: Wellness here is a funded commitment from leadership, not a perk on a slide.
A more predictable schedule: Defined onsite hours with time built in for notes and programming.
Voice in the program: You'll help shape how this works, with a partner on our team to build it with you.
A front-row seat: You'll spend your days inside one of the more interesting companies in AI, working with the people building it.
Why You Might Not Be Excited
The program is young. Some things will get figured out as we go, and you'll be part of figuring them out.
It's onsite and in person — this is a hands-on coaching role, not remote programming.
Your roster is our team, not the general public, so you won't be building an outside book of business here.
