About Workeron AI

Workeron AI is an AI Product Builder and AI Transformation partner. We create AI agents, multi-agent systems, internal AI tools, and AI-powered digital employees for founders, teams, and businesses.

We build fast, execution-focused AI products at the intersection of business, automation, and applied intelligence. Our goal is not just to develop software, but to launch working AI solutions that generate measurable value in real workflows.

We are looking for a strong senior-level builder who can independently design, prototype, and launch AI products, agentic systems, and scalable technical foundations for future growth.

Role mission

Your mission is to lead the technical creation of AI agents, multi-agent systems, and rapid product prototypes - from architecture and first implementation to deployable MVPs and pilot-ready solutions.

This is not a narrow executor role. We are looking for a senior engineer with strong product sense, system thinking, and startup execution speed - someone who can take raw ideas, shape technical solutions, build quickly, and help turn prototypes into real products.

What you will do

• Lead development of AI agents, multi-agent systems, and AI-powered product features
  
   
• Design and build production-minded MVPs and prototypes with high speed
  
   
• Define and implement client-server architecture for agentic products and workflows
  
   
• Build backend systems for orchestration, memory, tool execution, logging, permissions, and integrations
  
   
• Integrate LLMs, APIs, data sources, vector search, automations, and external services
  
   
• Create lightweight but strong user-facing products, internal tools, dashboards, and landing pages
  
   
• Make architecture decisions that balance speed, flexibility, and future scalability
  
   
• Work directly with founder and product direction to validate product hypotheses fast
  
   
• Bring technical clarity into ambiguous product ideas
  
   
• Improve system reliability, observability, evaluation quality, and iteration speed
  
   
• Support deployment, testing, iteration, and evolution from demo to stable product
  
   
• Contribute to technical standards, stack decisions, and engineering best practices inside the product builder
  
   

What we expect

Core requirements

• 5+ years of commercial development experience
  
   
• Strong hands-on experience in Python and/or JavaScript/TypeScript

• Experience building agents, multi-step reasoning systems, or multi-agent workflows
  
   
• Understanding of prompt engineering, memory design, context handling, evaluation, guardrails, and hallucination mitigation
  
   
• Understanding of latency, token economics, cost optimization, and AI system tradeoffs
  
   
• Experience with relevant frameworks such as LangChain, LangGraph, LlamaIndex, CrewAI, AutoGen, or similar
  
   
• Practical understanding of how to make AI systems useful, reliable, and commercially testable
  
   

Backend / system design

• Ability to design modular, pragmatic, and extensible architecture
  
   
• Strong understanding of auth, access control, logging, monitoring, and failure recovery
  
   
• Ability to build systems that are fast to launch but clean enough to evolve
  
   

Frontend / product packaging

• Ability to build simple, clean, and functional UI for MVPs, internal tools, and demos
  
   
• Experience with React, Next.js, or similar frontend stack
