It provides consulting and technology services to large enterprise clients, including organizations across finance, media, and technology sectors.

Project Description:

The client is supporting the implementation of an internal financial data platform in a client’s environment through a lift-and-shift deployment.

The goal is to adapt, integrate, and validate the existing platform within the client’s infrastructure — ensuring compliance with technical, security, and authentication standards.

You will work alongside a DevOps/Release Specialist and client-side engineering teams to adjust application components, integration logic, and deployment configurations for seamless operation within the target environment.

Must Have:

• 4+ years of experience as a Software Engineer (backend or integration-focused)
• Hands-on experience with Node.js, including API development and system integration
• Strong understanding of cloud environments and containerized deployments (Docker)
• Experience integrating with authentication and authorization systems (OAuth2, SAML, SSO)
• Excellent debugging, documentation, and communication skills in client-facing contexts
  
  

Nice to Have:

• Previous experience with lift-and-shift or migration projects
• Exposure to module bundling or frontend build tools
• Familiarity with CI/CD automation and deployment validation
• Knowledge of infrastructure-as-code principles
• Experience working in cross-functional and distributed engineering teams
• Golang programming language knowledge or ready to learn.
  
  

Responsibilities and Tasks:

• Collaborate with customer and technical teams to analyze environment-specific requirements and adapt components accordingly
• Contribute to backend and integration updates in Node.js, ensuring API compatibility and secure communication
• Support authentication integration with identity providers
• Validate and fine-tune the React-based frontend for environment compatibility and deployment readiness
• Participate in environment validation and testing across cloud-hosted and client-side environments
• Work closely with the DevOps/Release Specialist on deployment configuration, CI/CD integration, and release validation
• Prepare technical documentation and contribute to knowledge transfer for client teams
