📋 Description

• 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.

🎯 Requirements

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience. • 4+ years of back-end engineering experience, including production-grade, scalable systems in Node.js. • Strong experience designing and building RESTful APIs and microservices. • Solid experience with relational databases (we use PostgreSQL). • Hands-on experience with cloud infrastructure, ideally AWS, and comfort with serverless and event-driven patterns. • Experience with automated testing and a real commitment to code quality. • Experience building multi-tenant SaaS platforms. • Experience with AWS serverless specifically (Lambda, EventBridge, Cognito, OpenSearch) and infrastructure as code (SAM, CloudFormation, or similar). • Experience with message-based and event-driven architectures. • Experience integrating or building payments systems, and familiarity with PCI compliance. • Experience working with AI-assisted development tools in a production codebase.
