Job SummaryWe're hiring a Software Development Engineering in Test (SDET) to embed with 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—and that means quality has to scale the same way.This is not a QA-at-the-end role.
You'll be in the room when we design services, shaping what 'done' means before a line of code is written.
You'll execute against an established QA strategy and set of frameworks, with QA leadership provided by a senior team member who has deep context on how everything fits together.
Your focus is on building and running great tests—across unit, integration, contract, and end-to-end layers.
Because Platform services are consumed by many products simultaneously, a defect here is a defect everywhere.
You'll own quality as a first-class concern, not an afterthought.Duties and ResponsibilitiesDesign, 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 a quality-engineering perspective before implementation begins.Build and maintain CI/CD test pipelines that give the team fast, reliable feedback on every commit.Own test coverage for multi-tenant scenarios: tenant isolation, data separation, per-tenant configuration, and cross-tenant security boundaries.Write and maintain automated tests against AWS-native infrastructure—Lambda, EventBridge, SQS/SNS, API Gateway— including event-driven and async patterns.Define and enforce API contract testing so downstream product teams can integrate with confidence.Instrument test runs for observability: flakiness tracking, coverage trends, and test health dashboards.Monitor and track quality metrics—test coverage trends, defect escape rates, flakiness—and surface insights to the team regularly.Validate rollback and recovery behavior: ensure services degrade gracefully and recover correctly under failure conditions.Apply privacy and data protection considerations in test design: avoid using real PII in test data, validate data handling on sensitive paths, and flag compliance gaps.Identify and drive resolution of systemic quality gaps; bring data, not just opinions.Use AI coding tools (Claude Code, Cursor) as part of your daily workflow, and apply the same rigor to reviewing AI-generated test code as any other code.Partner with back-end engineers to raise the quality bar across the team—pairing, code reviews, and shared ownership of what we ship.Education and Experience4+ years of SDET or quality engineering experience working on production back-end systems.Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.Experience testing microservices and event-driven systems— you know how to test async flows, not just synchronous request/response.Solid experience with CI/CD pipelines and integrating test suites into them (GitHub Actions, CircleCI, or similar).
Experience testing against cloud infrastructure, ideally AWS.Experience testing multi-tenant SaaS platforms, especially around isolation and security boundaries.Hands-on experience with AWS serverless specifically: testing Lambda functions, EventBridge rules, and SQS/SNS workflows.Experience with performance and load testing frameworks (k6, Artillery, or similar).
Experience testing payments integrations or familiarity with PCI compliance requirements.Experience with infrastructure-as-code and testing infrastructure changes (SAM, CloudFormation, or similar).
Experience working with AI-assisted development tools in a production codebase.Knowledge, Skills and AbilitiesStrong understanding of relational databases (we use PostgreSQL) and how to test data integrity and migrations.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.Solid experience writing tests in JavaScript or TypeScript, with frameworks like Jest, Mocha, Playwright, or Selenium; familiarity with the Page Object Model (POM) pattern is a plus.Hands-on experience with API testing and contract testing (Pact or equivalent).
Work EnvironmentOffice setting with a moderate noise level.The employee will work at an individual workstation, using a telephone and computer.Physical DemandsMust 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.Neumo is an Equal Opportunity Employer.
Selection for a position will be made without regard to race, religion, national origin, sex, political affiliation, marital status, non-disqualifying physical handicap, and age.
