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
