Senior Quality Engineer(SDET)

Who we are

Endor Labs is building the Application Security platform for the software development revolution. Modern software is complex and dependency-rich, making it increasingly difficult to pinpoint the risks that truly matter. Endor Labs solves this challenge by building a call graph of your entire software estate—enabling teams to clearly identify, prioritize, and fix critical risks faster.

Trusted by companies that are one or one hundred years old, Endor Labs secures code whether it was written by humans or AI, and whether it's 40-year old C++ code or cutting edge Bazel Monorepos. Endor Labs was founded by serial entrepreneurs Varun Badhwar and Dimitri Stiliadis, and is backed by leading VC firms such as Dell Technology Capital, Lightspeed, and Sierra Ventures.

What you’ll do

We are looking for a Senior Software Engineer with a strong focus on Quality Engineering to drive the reliability, scalability, and security of Endor Labs’ products. This role goes beyond traditional QA - you will own quality end-to-end, combining deep technical expertise in automation with a strong understanding of real-world customer use cases.

You will play a key role in designing robust test strategies, building scalable automation frameworks, and integrating quality checks into CI/CD pipelines. The ideal candidate brings a security-first mindset, proactively identifies risks, and leverages modern AI-powered development tools to enhance productivity, debugging, and test coverage. This position requires both independent execution and strong collaboration within a fast-paced, high-impact engineering environment.

Own and drive end-to-end quality strategy for product features, from design to release.

Design, develop, and maintain scalable test automation frameworks and test suites.

Perform deep manual and exploratory testing for complex security use cases.

Integrate automated tests into CI/CD pipelines to ensure rapid and reliable releases.

Collaborate closely with engineering, product, and DevOps teams to define acceptance criteria and quality benchmarks.

Identify, debug, and root-cause complex issues using tools like logs, metrics, and observability platforms.

Contribute to release processes, including build validation, regression cycles, and production readiness

Leverage AI tools (e.g., Cursor, Claude) to improve development velocity, debugging, and test generation.

Continuously improve testing practices, frameworks, and tooling to increase efficiency and coverage.

Advocate for shift-left testing and quality ownership across teams.

What we're looking for

5 to 8 years of experience in software engineering or QA, with strong exposure to both manual and automation testing.

Proficiency in at least one programming language such as Java, Python, or Go.

Hands-on experience building or working with test automation frameworks (e.g., JUnit, TestNG, Pytest).

Strong understanding of CI/CD systems (Jenkins, GitHub Actions, GitLab CI) and modern release workflows.

Experience with version control (Git) and build/package tools like Maven, npm, or pip.

Solid understanding of REST APIs and experience with API testing tools (e.g., Postman).

Experience working with cloud platforms (AWS, Azure, or GCP).

Strong debugging and troubleshooting skills using tools like Splunk, Kibana, or similar log/observability platforms.

Familiarity with containerization and orchestration (Docker, Kubernetes) and DevOps practices.

Understanding of modern software delivery pipelines and release processes.

Experience working in or strong interest in the security/cybersecurity domain.

Demonstrated ability to leverage AI tools (e.g., Cursor, Claude) to improve development velocity, debugging, and test generation.

Foundational understanding of AI/ML concepts and their practical application in software engineering workflow.

At Endor Labs, we:

Go to extraordinary lengths to distinguish ourselves through world-class work.

Prioritize quality over speed, and speed over scope.

Desire working with deeply kind, mission-driven people.

Strive to make the complex simple.

Use first principles to debate ideas, test assumptions, and make decisions.

Seek the truth by putting data above opinions.

Assume good intent and give tactical feedback to help each other get better.

Hold no ego—when our customers win, we all win.
