Ditto AI is building the agentic social network where AI agents run the system, continuously learning and improving outcomes. In this Senior Full-stack Engineer role, you’ll help bring Ditto’s autonomous matchmaking and engagement engine to life, building customer-facing experiences and the internal tools that humans and AI rely on to observe, debug, and improve agent behavior. This is not a traditional full-stack role—you’ll collaborate with product, research, and infrastructure to shape the core of Ditto’s agentic platform.

What youll do

• Build agent-driven product flows across matching, chat, scheduling, and re-engagement.
• Own customer-facing social experiences powered by autonomous AI systems.
• Design and implement AI-orchestrated pipelines that replace manual workflows.
• Create internal tools for humans and AIs to inspect system state.
• Create internal tools for humans and AIs to debug agent behavior.
• Create internal tools for humans and AIs to evaluate outcomes.
• Create internal tools for humans and AIs to steer system direction.
• Implement feedback loops connecting user behavior, agent decisions, and real-world outcomes (matches, replies, dates, retention).
• Optimize the system for reliability, speed, and scale.

What Ditto AI is looking for

• 3+ years of software engineering experience.
• Experience contributing to AI-powered or agentic systems and automated workflows.
• Strong CS fundamentals with ability to design and build reliable, scalable systems.
• Familiarity with modern web tech stacks and full-stack development.
• Industry experience in consumer social networks, matchmaking, or AI-powered platforms is a plus.
