Senior Backend Platform Developer, Contact Center Systems

Senior Backend Platform Developer

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; you will design APIs, serverless services, data flows, observability tooling, and AI-enabled workflows that support our customer and agent experience.

The contact center is the domain, but the core need is strong development capability. The right person is comfortable building production systems, integrating complex platforms, and using AI-assisted engineering tools to move quickly without sacrificing quality.


What You'll Do

  • Develop production-grade Node.js services on AWS Lambda, API Gateway, and event-driven serverless patterns
  • Design and secure APIs and integrations across internal systems, customer data, and third-party platforms
  • Establish technical patterns, implementation standards, and reusable services for the broader contact center systems roadmap
  • Implement observability pipelines using:
    • OpenSearch
    • CloudWatch
    • Kibana
    • Snowflake
    • Structured logging
  • Develop automation and AI-enabled workflows improving:
    • Routing
    • Agent support
    • Troubleshooting
    • Operational visibility
  • Create migration tooling and services to transition legacy telephony and contact center workflows onto modern platforms, ensuring future scalability and resilience

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
