United States onlyLuma AI's mission is to build multimodal AI to expand human imagination and capabilities. We believe that multimodality is critical for intelligence. To go beyond language models and build more aware, capable and useful systems, the next step function change will come from vision. We are working on training and scaling up multimodal foundation models for systems that can see and understand, show and explain, and eventually interact with our world to effect change.
Our Dream Machine app is at the forefront of this vision, bringing powerful multimodal AI capabilities to users in an intuitive, delightful mobile experience. A product mindset: you care how things feel, not just if they work. As a lean, focused team backed by top-tier investors, we move quickly and give our engineers significant ownership over impactful projects.

Your Path to Joining
Our interview process is streamlined to respect your time while thoroughly evaluating fit:
Initial conversation with our founding team
Technical discussion focused on iOS development and system design
Practical coding exercise relevant to our product challenges
Virtual (or physical) onsite with team members from engineering, design, and product
Final discussions about role expectations and team fit
This is an on-site role in Palo Alto, California. Given our collaborative work style and the inventive nature of the products we are building, we’re fortunate to have a product team working together in-person. We find our hybrid work schedule ideal in allowing for periods of collaboration and discussion as well as time for focused solo work during each week.
We're committed to building a diverse team and strongly encourage candidates from all backgrounds to apply, especially those underrepresented in technology.
