Senior Systems Full-Stack Engineer

About the Role

As a Sr. Systems Full-Stack Engineer, you will bridge the gap between design and development by rapidly transforming concepts into production-ready applications using modern full-stack frameworks and AI design tools. You will play a key role in the early stages of innovation, taking ideas from concept to prototype to production with a strong focus on frontend excellence, design system alignment, and solid backend foundations. Leveraging tools like v0.dev, bolt.new, and Lovable, you will accelerate design-to-code workflows while ensuring every component meets enterprise standards for accessibility, performance, and scalability. You will collaborate closely with UX Designers, AI Builders, and Innovation Leads, using platforms like Figma and Supabase to deliver cohesive, high-quality applications. This role is ideal for someone who thrives in a fast-paced environment, enjoys experimentation, and has a passion for pushing the boundaries of what AI can achieve in modern software development.

Key Responsibilities

• Rapidly turn concepts into interactive prototypes using AI design tools (v0.dev, bolt.new, Lovable, etc.).
• Build secure, scalable full-stack applications from prototype to production, emphasizing robust backend architecture, relational database design, and complex logic structures.
• Develop and translate UI prototypes into production-ready frontends, adapting flexibly across modern JavaScript frameworks (React/Vue) and structured low-code enterprise platforms (OutSystems) based on client needs.
• Align all components with existing design systems, including tokens, color, typography, and brand guidelines.
• Design and implement RESTful APIs and backend services (e.g., Supabase), integrating SQL/NoSQL databases for efficient data management.
• Implement authentication, caching, and performance optimizations across the stack.
• Collaborate with UX Designers, AI Builders, and Innovation Leads throughout the development lifecycle.
• Maintain component libraries and design systems in Figma to streamline design–dev workflows.
• Document technical decisions and implementations in Jira.

Qualification

• 6+ years of full-stack development experience.
• Strong foundational understanding of web architecture, with expertise bridging modern JavaScript frameworks (React, Vue) and enterprise application platforms (e.g., OutSystems, Appian).
• Proven backend experience with a strong emphasis on relational database design (SQL), complex logic structures, and strongly-typed/compiled environments (e.g., C#, Java, TypeScript).
• Hands-on experience with AI design tools (v0.dev, bolt.new, Lovable) and workflow automation (N8N).
• Strong background in backend development, including API design (REST/GraphQL) and database management (PostgreSQL, MySQL, MongoDB).
• Skilled in authentication (OAuth, JWT), caching, and performance optimization.
• Deep understanding of design systems, tokens, and component-driven development.
• Expert Figma user, proficient with design system management and CSS frameworks (e.g., TailwindCSS).
• Experienced with TypeScript, modern JavaScript (ES6+), and cloud deployment (AWS, Azure, GCP).
• Proven track record of delivering production-grade applications and maintaining high attention to detail.
• Strong collaboration, problem-solving, and adaptability in fast-paced environments.
• Portfolio demonstrating full-stack builds, design system work, and AI design tool use.
• Previous working experience with OutSystems is a plus
• Experience in the Insurance sector is a bonus
