Neumo; Región Centro; Híbrido; MXN 420.000 - 640.000; Jornada completa

Descripción de la vacante

Neumo is seeking a Software Development Engineer in Test (SDET) to join the Platform team in Guadalajara. You will design and run automated tests across unit, integration, contract, and end-to-end layers for Node.js services, shaping what 'done' means before code is written.

You will own test frameworks, CI/CD pipelines, API contract testing, and multi-tenant security validation, while collaborating with back-end engineers to raise the quality bar.

Formación

• 4+ years of SDET or quality engineering experience
• Bachelor's degree in Computer Science, Engineering, or related field
• Experience testing microservices and event-driven systems
• CI/CD pipelines experience with GitHub Actions or CircleCI
• Experience testing against AWS cloud infrastructure
• Multi-tenant SaaS testing, isolation and security focus
• Hands-on with AWS serverless testing (Lambda, EventBridge, SQS/SNS)
• Experience with performance and load testing tools (k6, Artillery)
• Testing payments integrations or PCI compliance familiarity
• Infrastructure-as-code testing (SAM, CloudFormation)
• AI-assisted development tool usage in production codebases

Responsabilidades

• Design, build, and maintain automated test frameworks across unit, integration, contract, and end-to-end layers for Node.js shared services.
• Participate in service design and API reviews from day one, contributing with quality-engineering perspective.
• Build and maintain CI/CD test pipelines with fast, reliable feedback on commits.
• Own test coverage for multi-tenant SaaS scenarios: tenant isolation and data separation.
• Write and maintain automated tests against AWS-native infrastructure (Lambda, EventBridge, SQS/SNS, API Gateway).
• Define and enforce API contract testing for downstream product teams.
• Instrument test runs for observability: coverage trends and test health dashboards.
• Validate rollback and recovery behavior under failure conditions.
• Apply privacy and data protection considerations in test design.
• Collaborate with back-end engineers to raise the quality bar.
