Fullstack AI Agent Dev Senior (node.js + vue.js + claude code)

We are looking for Fullstack AI Agent Dev Senior (node.js + vue.js + claude code) with strong English skills to join us in a project with a Europe-based company. This is a remote position, and we will consider candidates from Portugal and a limited set of EU countries.

Our Client is a global player in the field of operations, risk, and sustainability services and solutions for companies and industries across the world. As they provide both services and technology for their clients, the Fullstack AI Agent Dev Senior (node.js + vue.js + claude code) we are looking for will support the delivery of value across client's operations and technology ecosystem.

In this position, you are hired by FCamara Europe, the European division of one of the largest and fast-growing tech and cognitive services group in Brazil, with +1500 specialists and engineers. From Portugal we deliver services to the EU, UK, US and MENA, bringing together multicultural, diverse and creative teams through projects, managed services, squads, and staff augmentation.

In this role, you will be primarily responsible for driving the structured adoption of AI-augmented software development (SDLC with Claude AI) across technology squads while delivering high-quality, hands-on full-stack web applications and APIs in Node.js and Vue.js.

In a typical week you will:

• Build, scale, and maintain hands-on back-end services (Node.js) and modern front-end interfaces (Vue.js) for high-scale SaaS platforms.
• Act as the team's Focal Point for AI Augmentation, embedding Claude AI across all SDLC phases (implementation, testing, code review, documentation, and maintenance).
• Utilize Claude Code in daily development workflows for repository-level tasks, diff reviews, and pull request management.
• Configure and maintain project context files (CLAUDE.md), defining development standards, guardrails, and acceptance criteria for AI agent usage.
• Create and maintain subagents, skills, and standardized prompt libraries for recurring engineering tasks.
• Integrate agents with internal tools, repositories, task managers, databases, and observability platforms via Model Context Protocol (MCP).
• Implement CI/CD quality automations using hooks and Claude for automated pull request reviews, compliance checks, and test coverage.
• Apply context engineering to large or legacy codebases, managing context window limits and performing systematic output validation.
• Conduct pair programming, developer onboarding, and hands-on enablement to build team capability in AI-assisted workflows.
• Monitor AI adoption metrics (lead time, PR throughput, defect rates) and define clear human-in-the-loop code review criteria.
• Maintain comprehensive documentation for APIs, architecture decisions, component design, and SDLC AI adoption guidelines.

Seniority: Due to the nature of the position, we are looking for someone with at least 5+ years of experience as a Fullstack Developer, using Claude Code in a daily basis professionally in the SDLC for, at least, 12 months.

To be considered for the role, it is mandatory you to fulfill these requirements:

• Solid back-end development experience with Node.js, RESTful/event-driven APIs, SOLID principles, and clean code practices.
• Solid front-end development experience with Vue.js (Composition API, state management, routing, HTML5, CSS3, JavaScript/TypeScript).
• Experience with reusable component architecture, Design Systems, and UI component libraries (e.g., PrimeVue, eCharts).
• Mandatory, proven experience applying Claude AI across the SDLC (implementation, testing, code review, documentation, maintenance).
• Hands-on proficiency with Claude Code for repository-level tasks, diff reviews, branch workflows, and PR integrations.
• Hands-on experience configuring and managing CLAUDE.md context files, custom subagents, skills, and prompt templates.
• Experience with MCP (Model Context Protocol) integration, connecting AI agents to dev tools, databases, and platform ecosystems.
• Experience setting up CI/CD pipeline automations using hooks and Claude for automated PR reviews and code quality checks.
• Experience with context engineering, task decomposition, and context window management on complex or legacy codebases.
• Solid understanding of cloud-native architectures, Azure cloud infrastructure, Docker containerization, Redis, and MongoDB (modeling, indexing, performance).
• Experience with API management, contract versioning, and end-to-end web security (OAuth2/OIDC, JWT, XSS/CSRF protection).
• Experience implementing automated testing (unit, integration, UI), web accessibility (A11y), performance profiling, and observability (logs, metrics, tracing).
• Building internal automations or agents with Claude Agent SDK / Claude API is considered a strong plus.

Beyond technical knowledge, we also expect you to have a collaborative and team-oriented profile:

• Technical excellence and commitment to writing clean, maintainable, and performant code across back-end and front-end.
• High technical autonomy to drive complex features and AI integrations end-to-end independently.
• Systemic vision to evaluate platform-wide architectural impacts of technical decisions.
• Strong collaboration and communication skills to work closely with UX, QA, DevOps, and multidisciplinary squads.
• Strong teaching ability and mentorship mindset to enable squad members in AI tool adoption without creating single-point dependencies.
• Productive skepticism toward AI: applying critical judgment, mandatory human verification, security checks, and full personal accountability for delivered code.
• Willingness to act as a hands-on Focal Point working directly within squads rather than taking a purely advisory role.
• Proactivity, strong analytical problem-solving skills, and a delivery mindset focused on performance, stability, and UX.

This is a fully remote position. You may occasionally be invited or requested to visit Client or FCamara sites in Portugal or Central Europe on an occasional, pre-planned basis. Regular office visits are not anticipated.
