You’ll collaborate closely with our CTO, cross-functional teams, and model providers to translate complex ideas into elegant, production-ready software. This is a hands-on leadership role where you’ll influence system design, mentor other engineers, and set the bar for engineering quality in a fast-moving, AI-native environment.

  • Evaluate new technologies, model APIs, and prompting strategies to enhance agent performance and alignment.
  • Collaborate cross-functionally with design, product, and GTM teams to define roadmaps and prioritize development.
  • Drive internal engineering standards through mentorship, documentation, and code reviews.

Requirements

  • 6+ years of experience in software engineering, with demonstrated leadership on complex technical projects.
  • Strong command of modern fullstack frameworks—especially Typescript, React, NextJS, and NodeJS.
  • Track record of shipping scalable systems in high-growth or startup environments.
  • Strategic thinker who can balance speed and quality while driving technical vision.
  • Bonus: experience with LLMs, agent orchestration frameworks, or AI infrastructure.
