[Hiring] Senior Software Development Engineer in Test @Suralink Inc

Role Description

We're seeking a Sr. Software Development Engineer in Test (SDET) to help champion quality across the stack and throughout the SDLC. You'll work cross-functionally to promote testing best practices throughout the entire testing pyramid, helping teams build reliable unit, integration, and E2E tests. You'll also take ownership of building and scaling automated test suites using Playwright and TypeScript.

Beyond automation, you'll be a key voice in both shift-level (early, embedded testing) and shift-right (Observability, testing in production, user behavior, validation) quality strategies--working to ensure quality doesn't stop at CI, but continues into real-world usage.

Key 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.

Qualifications

• 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.

Additional Preferred Qualifications

• 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.

Benefits

• Remote-friendly policy
• Medical/vision/dental insurance
• Flexible PTO policy and ten paid holidays
• Parental leave
• Professional development allowance
• Community involvement
