Senior Fullstack Developer (AI Chatbot / RAG Systems)
At Robots & Pencils, we build meaningful, scalable software experiences that help innovative organizations move faster and smarter. We are seeking a Senior Fullstack Developer to support the rapid development of an AI-powered chatbot platform leveraging Retrieval-Augmented Generation (RAG). This role is ideal for an experienced engineer who thrives in fast-paced environments, enjoys building across the stack, and is excited to work at the intersection of modern web development and AI systems.
In this role, you will work as part of a strategic, embedded delivery team focused on prototyping and production readiness for AI-driven solutions. You will collaborate closely with UX designers, AI engineers, and client stakeholders to iterate on user interfaces, build supporting backend systems, and help de-risk the solution as it evolves toward production. Your work will be highly visible and critical in shaping both the technical foundation and user experience of an emerging AI product.
Key Responsibilities
Fullstack Engineering & Application Development
Design, build, and iterate on frontend applications using React
Develop backend services and APIs using C# / .NET to support AI-driven workflows
Rapidly prototype and refine features to validate requirements and technical feasibility
Contribute to scalable, maintainable codebases aligned with engineering best practices
Support deployment readiness, including performance considerations and system stability
AI-Augmented Development
Treat AI-assisted development (e.g., Claude Code, Kiro, Cursor, GitHub Copilot) as a baseline capability, integrating these tools seamlessly into your daily workflow to improve speed and efficiency
Apply thoughtful prompt engineering and structured interaction patterns to produce reliable, maintainable code
Go beyond basic AI assistance by leveraging more advanced techniques (e.g., spec-driven development, test-driven prompting, and iterative refinement workflows) to improve code quality, consistency, and alignment with requirements
Use AI tools to support the full development lifecycle, including design exploration, implementation, testing, and documentation
Stay current with the rapidly evolving AI tooling landscape, critically evaluating and adopting new tools or practices that meaningfully improve developer productivity and outcomes
AI System Integration & Prototyping
Collaborate with AI Engineers to integrate chatbot functionality powered by RAG architectures
Build supporting services and interfaces that enable seamless interaction with AI models
Help de-risk AI solutions by validating technical assumptions and identifying potential gaps
Contribute to shaping system architecture for future production-scale implementation
Client-Facing Development & Collaboration
Work directly with client stakeholders to understand requirements and translate them into technical solutions
Collaborate with UX designers to iterate on UI/UX and deliver intuitive user experiences
Participate in regular client discussions, demos, and feedback sessions
Communicate technical decisions clearly to both technical and non-technical audiences
API Development & Platform Integration
Develop and maintain APIs that connect frontend applications with backend and AI services
Integrate with external systems and data sources as needed for chatbot functionality
Contribute to architectural decisions ensuring scalability, reliability, and flexibility
Quality, Testing & Engineering Excellence
Write clean, testable, and maintainable code
Participate in code reviews and contribute to continuous improvement of engineering standards
Collaborate with team members to troubleshoot and resolve issues efficiently
Collaboration, Communication & Mentorship
Work closely within a cross-functional team including designers, engineers, and AI specialists
Provide technical guidance and share knowledge within the team
Communicate progress, risks, and solutions effectively across stakeholders
Innovation & Continuous Improvement
Stay current with evolving AI technologies and frontend/backend best practices
Explore new tools and approaches to improve speed, quality, and system design
Contribute to the advancement of AI-driven product development within the organization
Required Skills & Experience
B.S. in Computer Science, Computer Engineering, or equivalent experience
5+ years of professional software development experience delivering production applications
Strong experience with:
React (frontend development)
C# / .NET (backend development)
Experience building and integrating APIs
Strong understanding of modern application architecture and development best practices
Demonstrated experience using AI coding tools (e.g., GitHub Copilot, Cursor, Claude) as part of daily development workflow
Experience working in fast-paced, iterative development environments
Comfortable working in client-facing roles
Tech Stack You Will Work With
Frontend: React, JavaScript / TypeScript
Backend: C#, .NET
AI / Systems: RAG-based architectures, AI integrations
AI Dev Tooling: Claude Code, Kiro, Cursor, GitHub Copilot, or equivalent AI-assisted development tools
Cloud & DevOps: AWS or Azure (environment-dependent), CI/CD pipelines
Tooling: Git, modern IDEs, testing frameworks
Personal Attributes
Fast-Moving Builder: Thrives in rapid prototyping and iterative development environments
Collaborative: Works effectively across design, AI, and engineering teams
Client-Centered: Comfortable engaging directly with stakeholders and adapting to feedback
Curious & Adaptable: Excited by emerging AI technologies and evolving requirements
Solution-Oriented: Focuses on delivering practical, scalable outcomes
