The future of AI — whether in training or evaluation, classical ML or agentic workflows — starts with high-quality data.

At HumanSignal, we’re building the platform that powers the creation, curation, and evaluation of that data. From fine-tuning foundation models to validating agent behaviors in production, our tools are used by leading AI teams to ensure models are grounded in real-world signal, not noise.

Our open-source product, Label Studio, has become the de facto standard for labeling and evaluating data across modalities — from text and images to time series and agents-in-environments. With over 250,000 users and hundreds of millions of labeled samples, it’s the most widely adopted OSS solution for teams working on building AI systems.

Label Studio Enterprise builds on that traction with the security, collaboration, and scalability features needed to support mission-critical AI pipelines — powering everything from model training datasets to eval test sets to continuous feedback loops.We started before foundation models were mainstream, and we’re doubling down now that AI is eating the world. If you're excited to help leading AI teams build smarter, more accurate systems — we’d love to talk.

HumanSignal is building the world's first dedicated data creation labs—facilities where expert annotators, domain specialists, and AI trainers create the highest-quality training data in the industry.

We're hiring an AI Trainer Onboarding and Support Specialist to be the first point of contact for our growing community of AI trainers. You'll help new trainers get started, answer their questions, resolve issues quickly, and make sure everyone has what they need to do their best work.

This role is all about people. You'll be the friendly voice (or message) that helps someone navigate their first annotation task, troubleshoot a technical issue, or understand their payment. You'll work across time zones to support a global workforce, and you'll play a key role in making HumanSignal a place where talented people want to contribute.

If you're someone who genuinely enjoys helping people, thrives on solving problems, and wants to be part of building something new, we'd love to hear from you.

You will:

Respond to support tickets from AI trainers across multiple channels—email, chat, and internal platforms
Guide new trainers through onboarding: answering questions, troubleshooting setup issues, and helping them get started on their first tasks
Handle questions about payments, scheduling, task assignments, platform navigation, and general policies

Create and maintain help documentation, FAQs, and onboarding materials based on common questions
Track support metrics and identify patterns that can improve the trainer experience
Work closely with operations and product teams to communicate trainer feedback and help improve our systems
Maintain a fixed schedule that may include night or weekend shifts to support trainers across time zones
Help build a welcoming, supportive community for our global network of AI trainers

You have:

2+ years of experience in customer support, onboarding, or community management roles
Genuine passion for helping people and solving their problems
Excellent written communication skills—you're clear, friendly, and empathetic
Strong problem-solving skills and the ability to think on your feet
Comfort with technology and the ability to learn new tools quickly
High attention to detail and organizational skills
Ability to work a fixed schedule, including potential night or weekend shifts
Experience working independently and managing your own workload
Patience and professionalism, even in challenging situations

Nice to have:

Experience supporting remote or distributed workforces
Familiarity with support ticketing systems (Zendesk, Intercom, etc.)
Background in data annotation, AI/ML, or tech platforms
Multilingual capabilities, especially Spanish, Portuguese, or other widely spoken languages
Experience creating help documentation or training materials
Interest in AI and machine learning

Compensation:

The base salary range for this full-time position is $60,000–$80,000 USD, plus benefits. This role is open to candidates internationally. Final compensation will be determined by experience, skills, location, and interview performance.
