Job description

We are looking for a Senior Backend Platform Developer to build modern services for Navan’s contact center systems. This is a software engineering role first: where you will design APIs, serverless services, data flows, observability tooling, and AI-enabled workflows that support our customer and agent experience.

What You'll Do

• Production-grade Node.js services on AWS Lambda, API Gateway, and event-driven serverless patterns.
• Secure APIs and integrations across internal systems, customer data, and third-party platforms.
• Technical patterns, implementation standards, and reusable services for the broader contact center systems roadmap.
• Observability pipelines using OpenSearch, CloudWatch, Kibana, Snowflake, and structured logging.
• Automation and AI-enabled workflows that improve routing, agent support, troubleshooting, and operational visibility.
• Migration tooling and services that help move legacy telephony and contact center workflows onto modern platforms, with enough design discipline to support future scale.

What We're Looking For

• 5+ years of backend software engineering experience, ideally with Node.js or TypeScript.
• Strong API design, system architecture, integration, debugging, and asynchronous systems experience.
• Hands-on experience with AWS Lambda or similar cloud/serverless architecture.
• Experience with logging, monitoring, search, data pipelines, or production observability.
• Practical use of AI coding assistants for development, testing, refactoring, and troubleshooting.
• Fluency with GitHub workflows, including pull requests, code review, branching, and CI/CD collaboration.
• Senior-level judgment to turn ambiguous operational problems into clean, maintainable technical solutions.

Helpful Domain Experience

• Experience in contact center, telephony, customer support, or workflow automation environments.
• Exposure to platforms such as Genesys Cloud, Twilio, Five9, NICE, Zoom Contact Center, or Avaya.
• Familiarity with routing, queues, IVR, SIP, phone number management, call metadata, or agent-assist workflows.
• Experience with Snowflake SQL, Terraform, CloudFormation, AWS SAM, or related infrastructure tooling.

This senior role will help Navan modernize the technical foundation behind our contact center environment. The work includes legacy platform migration, improved reliability and observability, AI-enabled automation, and new services that make our customer and agent experiences faster, smarter, and easier to operate.
