Senior GenAI Software Engineer

What You'll Do

• Architect and ship AI systems that generate ad creatives end-to-end - including interactive playables - combining code generation, multimodal asset generation, and runtime quality into production-grade pipelines
• Rapidly prototype against real creative problems, then take what works from proof-of-concept to production at speed
• Partner closely with creative strategists, content leads, and builders to translate craft expertise into systems that scale
• Design robust systems that handle the inherent variability of AI-generated output through thoughtful guardrails, fallbacks, and quality gates
• Build evaluation infrastructure tailored to creative output, spanning subjective quality assessment, human-in-the-loop review, and A/B testing against real ad performance
• Drive innovation by researching new model capabilities and proposing new initiatives as the frontier moves
• Mentor the team and raise the bar on engineering practices, fostering an environment of open feedback and shared learning

• Strong in Python for AI/agent work and fluent in JavaScript/TypeScript for creative and playables work; HTML and gaming experience a plus
• Has shipped LLM-powered systems to production, learned the failure modes firsthand, and makes deliberate choices about what the model handles versus what belongs in code, tools, or context
• Treats evals as first-class infrastructure and brings hands-on production experience with multimodal AI, specifically image and/or video generation models, with battle-tested intuition for where they excel and where they break
• Clear communicator who collaborates well across teams and disciplines, navigating ambiguity and adapting as priorities shift
