Job Summary
Kakegroup is hiring a remote candidate for Senior Fullstack Engineer (Next.js/AI Agents). This is a contract position. Work location: USA. The role typically involves technologies such as React, Next.js, REST, Figma, Design Systems, Artificial Intelligence (AI). We're looking for a product-minded fullstack engineer to join a fast-moving team building AI-powered products at the intersection of great UX and applied AI. This role is heavy on product thinking, UI craft, and building with multi-agent systems and LLMs - not on infrastructure or distributed systems work. You'll be working across a modern Next.js/React stack while designing agentic workflows and MCP server integrations, so strong instincts for both clean interfaces and reliable AI system design are essential. This is a great fit for someone who loves building polished, delightful products and is excited to work at the leading edge of applied AI (multi-agent systems, RAG, voice agents).
Key Responsibilities
Design, build, and ship fullstack features across the product, from UI to backend logic
Build and maintain agentic workflows, including multi-agent systems and MCP server integrations
Collaborate closely with design to implement polished, animated, high-quality UI using Material UI and Figma specs
Build and maintain RAG pipelines and integrations with multiple LLM providers (Gemini, GPT, Claude, Perplexity)
Work with async job processing (Inngest) and Postgres-backed data models
Contribute to internal tooling and back-office workflows (Retool)
Partner with product and design to translate requirements into technical solutions
Write clean, maintainable code and participate in code review
Core Requirements
Strong experience with Next.js (Pages Router) and React 18
Experience building and reasoning about multi-agent AI systems and agentic workflows
Solid backend experience with Postgres and building APIs (e.g., Next.js API routes)
Strong product sense and a genuine interest in UI quality, animation, and design systems
Experience integrating with LLM APIs ( e.g., OpenAI, Anthropic, Gemini) and/or RAG pipelines
Excellent written and verbal communication skills in English
Ability to work independently in a remote, fast-paced environment
Nice-to-Have
Experience designing or building MCP (Model Context Protocol) servers
Experience building voice agents
Familiarity with Material UI and translating Figma designs into production UI
Experience with async job frameworks like Inngest
Familiarity with Qdrant or other vector databases for RAG
Experience using AI coding tools like Codex or Claude
Code Experience with Retool or similar internal tooling platforms
Additional US Timezone Overlap
Required overlap with 9am-3pm PT (GMT-7)
Product-Focused Role
This role is not infrastructure-heavy - you won't be working on massive distributed systems or large-scale data problems. The ideal candidate is more energized by product craft, UI polish, and applied AI than by backend scale challenges.
