Descripción del empleo

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 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.

Knowledge, Skills and Abilities

• Excellent written and verbal communication. Much of our team is distributed, so clear async communication matters.
• Highly motivated, self‑guiding, and a constant learner who still loves contributing to team design and discussion.
• Must possess excellent organizational and communication skills.
• Willingness to take on new challenges.
• Must be reliable and responsible with a high attention to detail and accuracy.
• Office setting with a moderate noise level.
• The employee will work at an individual workstation, using a telephone and computer.

Physical Demands

• Must be able to remain seated for extended periods.
• Regular use of a computer and other office machinery, such as printers and copy machines.
• Occasional movement around the office.
• Frequent communication via telephone.
