About The Position

Suralink is seeking a Sr. Software Development Engineer in Test (SDET) to champion quality across the stack and throughout the SDLC. This role involves cross-functional collaboration to promote testing best practices across the testing pyramid, including building reliable unit, integration, and E2E tests. The SDET will own the building and scaling of automated test suites using Playwright and TypeScript. Beyond automation, the role contributes to shift-level (early, embedded testing) and shift-right (Observability, testing in production, user behavior, validation) quality strategies, ensuring quality extends into real-world usage.

Requirements

5+ years in an SDET, QA Automation, or Software Engineering role with a strong focus on testing.
Solid experience with TypeScript and PlayWright (or similar browser automation frameworks).
Strong understanding of testing across the pyramid: unit, component, integration, E2E.
Experience with AWS and cloud-native application architectures.
Knowledge of CI/CD pipelines and test integration with tools like GitLab, GitHub Actions, or similar.
Ability to communicate effectively and collaborate across disciplines.

Nice To Haves

Experience with contract testing, mocking strategies, and service virtualization.
Familiarity with shift-right testing practices, such as synthetic monitoring, canary releases, A/B testing, or chaos testing.
Familiarity with tools for performance testing, observability, or synthetic monitoring (e.g., Elastic, k6, Artillery, Datadog).
Understanding of feature flagging and progressive delivery workflows.
Experience with AI Evals or tooling like Braintrust

Responsibilities

Collaborate with engineers, PMs, DevOps, and other SDETs to define and implement holistic test strategies across unit, integration, and E2E levels.
Build and maintain robust automated test frameworks using Playwright with TypeScript.
Help shift quality left by embedding testability and validation early in the design and development process.
Help shift quality right by integrating observability tools, monitoring key use flows in production, and validating real-world performance and resilience.
Support and advise on unit and service-level test implementation across frontend and backend teams.
Improve test feedback loops by maintaining reliable and fast pipelines in CI/CD.
Identify gaps in coverage, flakiness, and performance issues across the test ecosystem and lead efforts to address them.
Ensure test environments and data strategies are scalable, reproducible, and representative of production.
