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.
- AI at the core of everything - Agentic workflows, RAG, MCP integrations,



vector search - you'll be designing systems at the frontier of what's possible with AI today.
- Work directly with the Founder and technical leadership - High-trust, high-ownership role with direct exposure to product strategy and company-level technical decisions.
- Build the team as you lead it - You'll have a say in who gets hired and how engineering culture evolves as the project and team scale. Strong performance opens the door to leading future projects across our portfolio.

Benefits & Compensation

- $6,000-$7,000/month - paid in USD, bi-weekly via Deel
- Fully Remote - work from anywhere during 9am-5pm EST
- Full-time contractor role, tied initially to this specific client project, with strong potential to transition to other projects based on performance
- Paid PTO - accrual starts after a 3-month trial period
- Referral Program - earn a bonus for referring talent that gets hired

Please send your resume in English. Include the following depending on your role:

- LinkedIn Profile URL (always required)
- GitHub Repository - code samples or architecture work (required)
- Certifications - AWS or equivalent, if applicable
