Software Engineer - Full Stack, Ad Product

About Luma AI Luma'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. So, 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.

Where You Come In We are building the founding engineering team for a new product focused on AI-powered ad creation. The vision is to create a copilot AI tool for ad agencies. This is a cursor-like AI agent and platform that will interact with and automate complex creative workflows on behalf of users. As a founding Full Stack Engineer, you will be responsible for building the core application from the ground up. This is a high-autonomy role for a product-minded generalist who thrives on shipping 0-to-1 products and interfacing directly with customers in a fast-paced, ambiguous environment.

What You'll Do Build the primary application, including scalable, low-latency backend APIs and the user-facing interface that will define a new workflow for creative professionals. Design and build robust integrations with major ad platforms. Work across the full stack to ship new, user-facing products from scratch, demonstrating a "builder" mindset and a passion for creative tools. Collaborate directly with customers (ad agencies) to translate their creative needs and workflows into an intuitive and powerful product.

Who You Are You are a full-stack generalist with strong proficiency in backend languages like Python and familiarity with modern frontend frameworks like React and TypeScript. You have a proven track record of building 0-to-1, user-facing products from scratch. You have direct experience building AI agents, platforms, or tools that leverage large language models (LLMs). You have a strong product sense for creative tools and an intuition for building experiences that empower creative professionals. You have 5+ years of hands-on experience working on an ad-related product, such as an Ads Manager, a demand-side platform (DSP), or an ad exchange. You have hands-on experience with containerization and orchestration technologies like Docker and Kubernetes, and have deployed and managed systems on cloud platforms such as AWS, GCP, or Azure.

What Sets You Apart (Bonus Points) Experience as a founding engineer or demonstrated ability to thrive in a fast-paced, ambiguous environment. A high-energy, proactive approach to solving problems and a genuine passion for building creative tools that make a difference for our customers.
