Commitment:
Part-time

Compensation:
Equity only (founding-team level)

We spend at least a third of our lives working.

We believe that time should matter.

Jolo.ai is building a new kind of hiring and job discovery platform—one designed to reduce unconscious bias, improve retention, and help people find work they genuinely care about. Instead of optimizing for keywords, pedigree, or résumé theatrics, Jolo matches people and employers based on values, purpose, intrinsic motivation, and behavioral alignment—using behavioral science as our foundation and AI as our amplifier.

We’re early, thoughtful, and intentional. Our public beta is live, and we’re now building the intelligence layer that will power meaningful, fair, human-centered matching at scale.

We’re looking for a Data Scientist / Machine Learning Engineer to join Jolo as a founding technical partner and help shape the core of our matching and learning systems.

This is not a “take tickets and build models” role.

This is a chance to help define what should be modeled in the first place.

You’ll work closely with the founders to translate behavioral science concepts into real, production‑grade machine learning systems—and help decide what should not be automated.

• Designing and iterating on matching models that go beyond skills and keywords
• Translating behavioral science frameworks into features, signals, and representations
• Building and evaluating early‑stage ML models (classification, ranking, clustering, embeddings, etc.)
• Experimenting with anonymized data pipelines that reduce bias by design
• Helping define ethical, transparent, and human‑first AI principles for the platform
• Collaborating on product decisions where data, psychology, and UX intersect

• Have strong experience in data science, machine learning, or applied AI
• Are comfortable working with imperfect, early‑stage data
• Care deeply about how and why models are used—not just performance metrics
• Have experience with Python, ML frameworks, and modern data workflows
• Are excited by ambiguity and shaping something from zero to one
• Believe hiring should be fairer, more human, and more meaningful
• Titles matter less than mindset. We care more about curiosity, judgment, and integrity than about buzzwords.

• Equity only:
  This is a true ownership role, not a contract gig
• Founding impact:
  Your decisions will shape the core of the product
• Mission‑driven:
  We’re solving a real human problem, not chasing ad clicks
• Thoughtful AI:
  Behavioral science leads; machine learning supports
• Long‑term vision:
  We’re building for alignment, retention, and happiness—not just hires

People don’t fail jobs—jobs fail people when there’s misalignment.

If you want to help build technology that helps people find work they love and helps organizations build teams that last, we’d love to talk.
