Lightly AG is an ETH and HSG spin-off pioneering in machine learning and computer vision. Backed by Y Combinator and top-tier investors, our technology is used by global leaders in autonomous driving, medical imaging, and visual inspection.

We are looking for a working student to join our team as an AI Trainer, where your work helps improve the reliability and performance of AI systems. In this role, you’ll evaluate and refine AI-Models and their output, ensuring they meet quality standards, follow instructions, and respond appropriately to different contexts.

This is a great opportunity for a driven student who wants to gain hands-on experience in AI development while making a real contribution.

In this role, you will:

• Prompt-Response Evaluation: Assess if AI responses accurately address the prompt, follow instructions, and meet quality standards.
• Language & Context Check: Judge the AI’s understanding of English, including grammar, tone, and ability to handle nuance or ambiguity.
• Domain Relevance: Verify that responses fit within the expected domain (e.g., technical, general knowledge, conversational).
• Instruction Following: Identify when the AI deviates from the prompt or adds irrelevant information.
• Optional: If tasks involve visual outputs, check image accuracy and caption clarity (depending on project needs).

You’re a strong candidate if you:

• Excellent English skills (grammar, style, comprehension).
• Strong attention to detail and ability to apply guidelines consistently.
• Familiarity with AI and the use of LLMs
• Background in STEM, communications, education, or similar fields is a plus but not required.
• Are available for at least 20% (ideally 60%)

💡 Don’t meet every single requirement? That’s okay!

At Lightly, we believe in potential, growth, and learning. If you're excited about the role and think you could be a great fit, we encourage you to apply—even if your experience doesn’t match the job description 100%.

• Opportunity to work in a fast-paced, tech-driven environment.
• Career growth opportunities in a growing field of AI development and machine learning.
• Flexible work hours, pensums and remote work options.

Send us your CV and a short note about why this role excites you. If you’ve handled similar tasks before, we’d love to hear specific examples.

We look forward to hearing from you!
