About the role

We're looking for a QA/UAT Engineer who enjoys balancing automation with hands-on product validation.
This role sits at the intersection of automated testing, exploratory testing, browser automation, API validation, release readiness, and AI-assisted quality engineering.
You'll work across our API platform (Go/gRPC services for email, calendar, contacts, and scheduling) as well as our customer-facing experiences, helping ensure changes ship with confidence.

Perform user acceptance and exploratory testing. Validate real-world customer workflows before release, uncovering usability issues, edge cases, and regressions that automated tests may miss.
Automate browser-based workflows. Build and maintain end-to-end UI tests for our dashboard, scheduling products, and embedded experiences using frameworks such as Playwright, Cypress, or Selenium.
Investigate and triage defects. Reproduce issues, identify root causes, collaborate with engineers to drive resolution, and maintain clear documentation throughout the defect lifecycle.
Collaborate across engineering teams. Work closely with backend, frontend, platform, and product teams throughout the development lifecycle to build quality into the process from the start.
Design, implement, and own automated test suites across our API platform and customer-facing applications, including integration, functional, contract, and end-to-end testing.
Validate APIs and services.

2+ years of experience in software engineering, QA, SDET, Quality Engineering, or test automation-focused software engineering roles (including internships).
Experience designing and maintaining automated testing frameworks and suites.
Proficient in Go (Golang), Python, or Javascript, including the ability to read service code, understand application behavior, write tests, and debug failures.
Experience testing APIs, microservices, or distributed systems.
Familiarity with REST APIs, gRPC, contract testing, and API validation tools such as Postman, grpcurl, k6, or similar.
Hands-on experience with browser automation frameworks such as Playwright, Cypress, or Selenium.
Experience using AI-assisted development or testing tools, including Claude Code, Codex, Cursor, or similar coding agents.
Familiarity with CI/CD systems and modern cloud-native development environments.
Experience working with Docker, Kubernetes, GitHub Actions, kubectl, and GitOps-style deployment workflows.
Strong understanding of software testing principles, including test strategy, test planning, risk-based testing, and defect management.

Experience applying AI and LLM technologies to software testing workflows.
Proficiency with TypeScript or Python for automation and tooling.
Experience testing third-party integrations, OAuth flows, or identity systems.
Familiarity with observability platforms, including logs, metrics, and distributed tracing.
Experience with performance, load, or reliability testing.
Experience working with developer platforms, APIs, infrastructure products, or highly technical SaaS environments.

Build and maintain automated test coverage.
Develop and maintain test coverage for REST and gRPC services, ensuring reliability across email, calendar, contacts, scheduling, and third-party provider integrations.

At Nylas, we're building the infrastructure that powers modern communications.
Our APIs and platform help thousands of developers integrate email, calendar, scheduling, and contacts into their applications without having to manage the complexity underneath.
As our platform grows, so does the importance of quality.
We're evolving our quality engineering practice beyond the traditional SDET model and rethinking how testing fits into a modern engineering organization.
We believe quality is a shared responsibility, and we're investing in automation, AI-assisted workflows, and deeper collaboration between engineering and product teams to help us ship with confidence.
Our goal isn't simply to automate more tests.
It's to build a modern, AI-native quality engineering practice that enables teams to move faster while maintaining a high bar for reliability, usability, and engineering excellence.
Support release readiness. Participate in release validation efforts, helping ensure new features and platform changes meet quality standards before reaching customers.
