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.

Must-Haves

Leadership — 5–6+ years of proven experience in Team Lead and Solutions Architect roles, with a track record of leading cross-functional teams through the full SDLC, while remaining hands-on with code and architecture yourself

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





Industry Agnostic Experience — Background in data-driven decision-making within traditional industries such as Real Estate, Healthcare, Legal, or Marketing/Communications

Operational Data Flows — Familiarity with data orchestration for complex business models

Database Ecosystems — Knowledge of Snowflake, SQL Server, or PostgreSQL for robust data warehousing and orchestration

Full-Stack Awareness — Familiarity with Angular or modern frontend frameworks to ensure smooth data coordination across the entire stack

Legacy Systems Integration — Experience migrating or connecting data from traditional legacy systems to modern cloud environments

What You Will Do

Architectural Ownership — Set and own the cloud-native architecture on AWS for this MCP project, ensuring scalability and security from the ground up

Technical Team Leadership — Lead the technical team (engineers, AI specialists) building this project, staying hands-on with code and architecture decisions

Client-Facing Technical Voice — Be the primary technical point of contact with the client, translating complex architecture decisions into clear business value

Strategic AI Implementation — Define strategy for agentic workflows, RAG implementations, and MCP-based integrations

Quality & Mentorship — Conduct code reviews, enforce engineering best practices, and lead technical interviews to benchmark talent as the team scales

Why This Could Be Your Next Big Move

? Own the technical foundation of a new project — You'll be the first and most important technical hire, shaping the architecture and team from day one.
