Requirements

  • 5+ years of relevant software engineering experience, including strong foundations in system design, production debugging, and scalable backend architecture.
  • Proven experience building and shipping LLM-powered or GenAI systems into production, with a deep understanding of real-world failure modes and system tradeoffs.
  • Strong programming skills in Python for AI/agent development and proficiency in JavaScript/TypeScript for frontend, creative tooling, or interactive applications.
  • Hands-on experience with multimodal AI systems, including image and/or video generation models, diffusion models, or related generative technologies.
  • Strong understanding of evaluation methodologies for AI systems, including offline metrics, human evaluation, and experiment design (A/B testing).
  • Ability to design systems that balance model intelligence with deterministic logic, including tooling, context engineering, and system safeguards.
  • Excellent communication skills with the ability to collaborate across technical and non-technical teams in ambiguous, fast-evolving environments.

Responsibilities

  • Architect and deliver end-to-end GenAI systems for ad creative generation, including multimodal pipelines, code generation components, and interactive playable ad experiences in production environments.
  • Rapidly prototype experimental AI solutions, validate performance against real creative use cases, and transition successful prototypes into scalable, production-ready systems.
  • Design robust evaluation frameworks for generative outputs, including human-in-the-loop review systems, A/B testing frameworks, and automated quality assessment metrics.
  • Build and maintain AI agent systems that optimize creative workflows, incorporating guardrails, fallback mechanisms, and quality control layers to manage model variability.
  • Partner closely with creative strategists, product managers, and cross-functional engineering teams to translate domain expertise into scalable AI-driven systems.
  • Research emerging developments in LLMs, vision models, diffusion models, and multimodal AI, and translate insights into new product initiatives and technical capabilities.
  • Mentor engineers and contribute to engineering best practices, fostering a culture of experimentation, feedback, and technical excellence across the team.
