Project Brief
We are looking for a Solutions Architect and Team Lead to serve as the technical backbone of a new Model Context Protocol (MCP) project for one of our clients in the marketing and communications industry. This is the first and most critical hire for this project — you will own architecture decisions, lead the technical team, and act as the main technical voice with the client. This role requires staying hands-on: you'll be writing code and reviewing PRs yourself, not just directing others.

AI Expertise — 2–3+ years of hands-on experience in AI projects, including LLM ecosystems (OpenAI, Anthropic), orchestrators (LangChain / LangGraph), and RAG architectures
MCP Experience — Direct hands-on experience with Model Context Protocol (MCP)



or building agent-to-tool integration layers — this project is specifically building MCP infrastructure
AWS Mastery — Expert-level AWS across Lambda, S3, API Gateway, ECS/Fargate, SQS, Cognito, and more
Certifications — Must hold AWS Certifications (Solutions Architect Professional or equivalent)
Infrastructure & DevOps — Advanced Terraform (modules, remote state, multi-environment) and solid Docker containerization experience, including CI/CD pipelines via GitHub Actions
Programming — Strong Python proficiency for pipelines, API development, and data processing (Java backend knowledge a plus)
Data Architecture — Experience with Vector Databases, including index design, metadata schemas, and hybrid search
Communication — Exceptional English communication, able to navigate executive conversations and technical deep-dives equally well
Nice to Have
Multi-Agent Systems — Experience with agent orchestration frameworks (CrewAI, Strands, Bedrock AgentCore) beyond basic LangGraph implementation
