Leading platform for electronic agreements

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.

• 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.

• 8+ years of professional software development experience.
• Strong proficiency inTypeScript 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.

• 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 Dev Ops 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.

We offer*:

• Flexible working format - remote, office-based or flexible
• A competitive salary and good compensation package
• Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
• Active tech communities with regular knowledge sharing
