Solution Architect

The Solution Architect Role

At Exelab we don't sell off-the-shelf products: we build custom solutions, treating every client engagement as a mini product cycle. The Solution Architect is a senior full stack engineer with broader responsibility: the technical owner of the engagement, accountable end-to-end for one or more parallel projects, and still hands‑on in the codebase.

Our stack is polyglot by design: NodeJS and Python are first‑class backend languages and the Solution Architect is expected to be fluent in both. Python in particular plays a central role across data integrations, automations, and AI/ML workflows—a meaningful share of what we ship has Python at its core.

In our delivery framework, the Solution Architect works in a duo with the Value Builder:

• Value Builder → owns business value, client outcomes, product direction
• Solution Architect → owns solution design, technical feasibility, delivery quality

The two roles are peers. The partnership between them is what makes our engagements work.

Key Responsibilities

• Solution design — translate business problems into well‑architected technical solutions, balancing time‑to‑value, scalability, and maintainability
• Project technical ownership — full accountability for the technical outcome of one or more projects in parallel
• Hands‑on engineering — build full stack applications across NodeJS, Python, React/TypeScript, and AWS, staying close to the code
• AI‑assisted engineering leadership — be a power user of modern AI coding tools and agentic workflows, and help the team adopt them
• Engineering standards — set and uphold standards on testing, CI/CD, observability, and IaC (AWS CDK)

Cross‑functional collaboration — work in continuous dialogue with the Value Builder, Project Managers, and partner specialists.

Requirements

Experience

• 7+ years in full stack development, at least 2 in a senior/lead capacity
• Proven track record owning the technical side of projects end‑to‑end

Core technical stack

• NodeJS and its main backend frameworks
• Python as a first‑class backend language — for APIs, data processing, automations, and AI/ML workloads
• React and TypeScript for modern frontend development
• AWS, including IaC with AWS CDK
• Relational and non‑relational databases (e.g., MySQL, DynamoDB)
• RESTful APIs and third‑party integrations
• Git and modern development workflows

AI‑assisted engineering

• Demonstrated proficiency with AI coding tools (Claude Code, Cursor, Copilot, and similar) and agentic workflows
• Ability to evaluate, guide, and improve AI‑generated code—and to bring others along the same curve

Soft skills

• Excellent communication, technical and client‑facing
• Bias toward action, shipped outcomes, pragmatic trade‑offs
• Good command of English, written and spoken
• Italian language proficiency is mandatory

Nice to Have

• Previous experience in a startup or consulting environment
• High‑coverage automated testing experience
• Additional programming languages
• AWS or Azure certifications
• CRM, ERP, or Ecommerce integration projects
• Serverless architecture and microservices
• AI and data systems experience

Ideal profile: “7+ years in full stack development with at least 2 in a senior/lead role; proven track record owning the technical side of complex projects end‑to‑end; strong proficiency in NodeJS, Python, React/TypeScript, and AWS with AWS CDK; advanced practitioner of AI‑assisted engineering and agentic workflows; excellent communicator who thrives in tight collaboration with a Value Builder and an extended dev team.”
