Lead Fullstack (React+Next.js)

#4727 Our Client is building a SaaS platform used globally to streamline business-critical workflows and transform document-driven processes into intelligent, automated systems. Their platform powers agreement lifecycle experiences at a massive scale, serving millions of organizations across highly regulated and enterprise environments. The team develops a unified, widget-based frontend platform that standardizes how product teams deliver modern, high-performance user interfaces. This platform provides a shared shell, micro-frontend architecture, and automated CI/CD pipelines that distribute versioned UI components globally with high reliability.  Part of the work includes supporting secure, compliance-heavy environments designed for federal-grade workloads. Engineers design systems that are secure by default, privacy-aware, and built on zero-trust principles. The role involves solving advanced platform challenges such as resilient rollouts, deterministic builds, telemetry without exposing sensitive data, and high-availability architecture in constrained environments. This is an opportunity to shape platform standards, performance practices, and developer tooling in a system operating at meaningful scale. Responsibilities:• Design and implement reusable frontend components within a micro-frontend architecture. • Build and maintain a shared UI platform that enables consistent user experiences across products. • Develop scalable CI/CD pipelines that publish versioned frontend artifacts for global delivery. • Contribute to secure-by-default engineering patterns aligned with compliance requirements. • Optimize performance, observability, and reliability across distributed frontend systems. • Collaborate with cross-functional teams to define platform standards and engineering best practices. • Integrate frontend systems with RESTful and/or gRPC backend services. • Support high-availability deployments in regulated or restricted environments. Required Qualifications: • 8+ years of professional software development experience. • Strong proficiency in TypeScript and React. • Experience building reusable, production-grade frontend component libraries. • Experience with frontend testing frameworks and test automation. • Solid experience with Next.js, Node.js, and Express. • Proven track record delivering SaaS products. Preferred Qualifications: • Experience across the full software development lifecycle. • Familiarity with schema modeling (e.g., JSON Schema or XML Schema). • Experience with Agile and test-driven development methodologies. • Experience with Azure DevOps or comparable CI/CD tooling. • Knowledge of micro-frontend frameworks. • Experience building or consuming RESTful or gRPC services. • Strong written communication skills in asynchronous environments. • Passion for platform engineering and high-quality software craftsmanship.
