About Trainset.ai
n
Trainset.ai is building a compliance-first, enterprise-grade AI data labeling platform for companies that actually care about accuracy, security, and scale.
n
We already have:
n
n
Paying customers
n
Access to ~170,000 global freelance workers via existing micro-task platforms
n
Clear demand from AI teams needing human-in-the-loop labeling (vision, NLP, LLM evals, RLHF, etc.)
n
n
This is no longer an idea — it's an early business that needs a technical co-founder to help turn momentum into a real category-defining product.
n
Role
n
I'm looking for a CTO / Technical Co-Founder to own the technical vision and execution.
n
You'll be responsible for:
n
n
Architecting and scaling the core platform
n
Designing systems for QA, consensus labeling, auditability, and compliance
n
Making early technical decisions that will shape the company for years
n




Hiring and leading engineers as we grow
n
n
This is a builder role first, leadership role second.
n
Qualifications
n
Who You Are
n
n
A senior full-stack engineer or tech lead
n
Comfortable moving fast in early-stage chaos
n
Opinionated but pragmatic about architecture
n
Excited by AI tooling, marketplaces, or data infrastructure
n
Looking for real ownership, not just a job
n
n
Startup or scale-up experience is a big plus.
n
Equity & Compensation
n
n
50% equity, vesting over 4 years (standard founder vesting)
n
This is a true co-founder role — not a contractor, not "sweat equity theatre"
n
n
Why This Is Interesting
n
n
Real customers, real revenue
n
Clear path to enterprise deals
n
Solid leverage from existing worker network
n
Massive tailwinds from AI adoption
n
Opportunity to build something defensible, not just another SaaS wrapper
n
