Lead Engineer - AI Studio

The role

You will lead technical direction for the AI Studio app generation engine, an AI-based React application builder that creates websites and apps from natural language. You will design systems and write production code, and mentor engineers as an individual contributor.

What you will do

• Own architecture and scaling decisions for core AI Studio platform components
• Lead cross-cutting initiatives to improve system responsiveness, generation accuracy and robustness
• Build scalable, fault-tolerant LLM pipelines for content generation, layout creation and AI-driven user guidance
• Design distributed systems that handle high-throughput generative and analytical workloads
• Build and optimize embeddings pipelines, retrieval-augmented generation and multi-agent orchestration
• Drive observability improvements and establish SLOs for latency, correctness, safety and uptime
• Strengthen resiliency and failover strategies for traffic spikes and model load variations
• Implement hallucination mitigation strategies and collaborate on data governance and privacy
• Mentor engineers through code reviews, design discussions and pairing
• Partner with PMs, designers and engineering leaders on the roadmap; take part in on-call rotations

Required qualifications

• 6+ years of backend engineering experience, including distributed system design and high-scale platform development
• Strong proficiency in Go (Golang) for concurrent backend services, alongside Node/NestJS experience
• Hands-on experience with Cloudflare Workers and Cloudflare KV (or comparable edge compute and distributed key-value stores)
• Deep expertise in event-driven architectures, asynchronous workflows and high-throughput data pipelines
• Strong command of PostgreSQL and NoSQL data models, query optimization and transactional data
• Fluency in LLM integrations, vector search, embeddings, RAG patterns and generative AI frameworks
• Familiarity with frontend architecture using Vue and a solid understanding of UI/UX principles
• Experience with monitoring, alerting and incident response for production systems
• Strong instincts for scaling, latency optimization and reliability under real-world load
• Experience implementing structured generation, verification layers, retrieval grounding and guardrails
• Understanding of prompt engineering patterns, context injection and model evaluation
• Exceptional communication and cross-functional leadership capabilities
