Software Engineer - AI Agents

About LumaLuma’s mission is to build multimodal AI that expands human imagination. We’re creating the Creative Partner, an AI agent designed to amplify, not replace, human creativity.This is a rare opportunity to define and build a novel agentic system from the ground up. You’ll be working at the frontier, creating new interaction paradigms for a product that will reach millions, and turning ambitious research into something magical, reliable, and scalable.What You’ll DoThis is not a role for maintaining legacy systems or making incremental tweaks. This is a zero-to-one opportunity to build the future of creative interaction. You will:

• Invent from First Principles: Architect the core of our agentic stack, moving beyond standard patterns to create a truly novel visual reasoning system.
• Ship Frontier Prototypes: Rapidly prototype and ship breakthrough agentic workflows that explore the absolute edge of creative AI, pushing past the limitations of today's VLMs and RAG systems.
• Build for Scale & Magic: Own the systems that make these experiences possible, ensuring they are low-latency, high-fidelity, and reliable for millions of creators.
• Bridge Research to Product: Partner directly with our world-class research and design teams to transform bleeding-edge models into magical, intuitive product experiences.

What We’re Looking ForWe’re seeking a proven builder with deep technical skills, product intuition, and a passion for how AI can augment creativity.You might lean toward:

• Creative prototyping: building imaginative agent experiences from first principles.
• Systems scaling: architecting low-latency agentic platforms for millions of users.

Either way, you’ve shipped ambitious projects, think from the user’s perspective, and thrive in fast-paced, ambiguous environments. Above all, you are driven by a genuine curiosity to discover what's possible at the intersection of AI and human creativity.Who You Are

• 5+ years of professional engineering experience OR an equivalent portfolio of advanced, relevant projects.
• Demonstrated ability to build experiences that cross modalities, with VLMs, diffusion models, or other multimodal systems (speech, video, etc.)
• Strong proficiency in Python and a solid understanding of backend systems and databases.
• Deep experience with AI/LLM frameworks with a track record of pushing beyond their standard functionality.

What Sets You Apart (Bonus Points)

• Experience in Rust or Go.
• Experience with fine-tuning, reinforcement learning, etc.
• Familiarity with Kubernetes, Docker, or modern cloud infrastructure.
• Background in multimodal systems, especially creative tools involving video or images.
• Highly Encouraged: Portfolio links, open-source contributions, or notable hackathon projects.
