About Contra Labs
Contra Labs sits at the intersection of human creativity and AI. We partner with leading AI labs and product companies to improve their tools across design, video, development, and beyond. Our research is grounded in how top creatives actually work, studying the patterns behind what gets created, what gets chosen, and what resonates. We believe human input will always be at the center of net new creation, and our mission is to help shape technology so human creativity can be amplified to create what today is unimaginable.
By joining the Contra Labs network you gain access to paid projects with some of the most innovative companies building the next generation of creative and AI-powered tools.
How It Works
This is an application to join the network and be eligible for roles as they arise. Projects are staffed on an as-needed basis, typically 5 to 10 hours at a time, though some may extend into longer engagements. In unique cases, we may have full-time roles available as well. When a project matches your skill set, we'll reach out with details and timeline.
To Join the Network
Portfolio review - We'll assess your Contra profile and portfolio for strength in content design, with a focus on ad creative and performance-driven visual content.
Record a 30 second intro video - Share a quick 30 second introduction so we can get to know you.
Complete profile - Once you’ve applied, we recommend completing your profile for better job matches and setting up your wallet so you can get paid when a job comes through.
What You May Work On
Evaluate AI-generated 3D scenes, interactive environments, simulations, and spatial experiences for visual and technical quality
Provide clear, structured feedback on scene composition, lighting, materials, physical dynamics, asset integration, interaction, and overall visual coherence
Help define quality benchmarks and evaluation criteria for what great AI-generated 3D experiences should look and feel like
Identify common failure modes in AI-generated 3D work, from broken physics and interactions to poor spatial composition or inconsistent visual feedback
Create reference examples, prototypes, or "golden" outputs that demonstrate best-in-class 3D execution
Contribute to research exploring how AI models can better understand and generate interactive 3D experiences
What We're Looking For
- Strong portfolio showcasing high-quality 3D design, interactive environments, or spatial experiences
Strong understanding of 3D composition, lighting, materials, animation, and visual coherence
Ability to articulate creative and technical feedback clearly and constructively
Strong 3D design instincts and awareness of contemporary visual culture, 3D trends, and emerging digital aesthetics
Comfort working in fast-paced, experimental environments (experience with AI, 3D tools, or creative technology is a plus)
