Job Summary:

We're hiring back-end engineers for our Platform team. Platform builds the shared services every Neumo application consumes: reporting, payments, search, authentication, messaging, file handling, and more. Our guiding principle is build once, use everywhere. When three products need the same capability, Platform owns it.

This is not single-product work. You'll design services that have to be reliable, secure, and multi-tenant from day one, because they're used by many applications at once. On any given day you might architect a new service, refactor an existing one to scale, instrument it for production, or pair with a product team to turn their requirements into a clean platform API.

Duties and Responsibilities:

Architect, build, and operate shared back-end services in Node.js that are consumed across Neumo's product portfolio.
Design for multi-tenancy from the start: tenant isolation, data separation, and per-tenant configuration are core to everything we build.
Build event-driven, serverless systems on AWS (Lambda, EventBridge, SQS/SNS, S3, RDS, Redshift).




Own your services in production: monitoring, tracing, alerting, and incident response, not just the first deploy.
Write and maintain automated tests across unit, integration, and regression layers, and keep coverage high.
Treat security as part of the definition of done: dependency and vulnerability remediation, secrets management, and compliance on sensitive paths like payments.
Use AI coding tools (Claude Code, Cursor) as part of your daily workflow, and review AI-generated code with the same rigor you'd apply to your own.
Participate in design reviews and code reviews, and share what you learn so the whole team levels up.
Partner with product and design to translate end-user requirements into pragmatic, scalable technical solutions.
Perform other duties as assigned.

Education and Experience:

Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical exp
