Software Development Engineer in Test

About the role

As a SDET Engineer, you’ll make sure we ship a polished product. You’ll design and evolve the safety net that keeps bugs from slipping through by contributing to our modern test automation platform and owning test strategy across UI, API, integration, and performance. You’re comfortable speaking up for quality when deadlines loom, and you collaborate closely with Engineering, Product, and company leadership to set clear acceptance criteria and make smart release decisions.

The work is far from routine. You’ll test a rich UI, a microservices backend with demanding performance and scalability needs, deep client integrations on Windows, macOS, and Linux, and a wide array of cloud APIs that connect to leading SaaS applications. If you enjoy building robust automation, breaking things the right way, and raising the bar for reliability, this role is for you.

What you'll do

• Develop and maintain scalable test frameworks.

• Perform API testing, UI testing, and end-to-end testing of our AI data lineage engine.

• Leverage AI for test automation.

• Build and maintain CI/CD pipelines and test automation systems.

• Deliver new automated tests across multiple applications and projects.

• Support release preparation and conduct release testing.

• Collaborate closely with developers to ensure product specifications are accurately implemented and tested.

Who you are

• Software engineer with experience in architecting and scaling automated test systems.

• Proficient in at least one of our primary programming languages: Golang, Python, or TypeScript. (While expertise in all three isn’t required, strong skills in at least one are essential.)

• Passionate about writing clean code and building innovative solutions.

• A break-it mindset — able to anticipate, identify, and prevent subtle bugs and edge cases.

• Hands-on experience with automated testing of APIs and web applications, including performance testing.

• Strong knowledge of modern CI/CD practices and tools, especially GitHub Actions.

• High attention to detail and commitment to maintaining top-tier product quality.

• Solid understanding of client-server architecture, REST APIs, gRPC, and streaming protocols.

• Comfortable operating in a fast-paced, agile environment.

• Energized by working with a dynamic, collaborative team.

• Excellent written and verbal communication skills in English.
