For many organizations, the most valuable asset is their data. Whether source code, product designs, customer records, financial results, or pricing models, every organization has information they don’t want to get in the hands of competitors, sold on darknet marketplaces, or exposed publicly. Keeping that data safe has been a challenge, until now. Cyberhaven gives organizations the tools to safeguard their data from theft or misuse. In the process, we’ve become the standard for Data Detection and Response (DDR), the category we helped create.

We need you to make sure we are shipping a shiny and polished product, free from hitches, glitches, snags, hiccups, crashes, or any other defects. You'll be architecting and developing a safety net that makes it hard for bugs to sneak through. This involves contributing to our modern test automation platform. You won't be afraid to speak up for quality when a deadline is approaching and there is pressure to roll features out. You'll be an advocate for quality-first development practices, working side-by-side with our development team to instill a test-first mindset across the organization. You'll be in close contract with the development and product teams as well as company founders and executives.

Exciting stuff is waiting for you! We’ve got a pretty cool tech stack over here and making sure everything is tested inside out is not exactly a routine task. There’s a rich UI, a microservices-based backend with steep performance and scalability requirements, deep integration with Windows, macOS and Linux, and a diverse set of cloud APIs for integration with SaaS applications.

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.

  • Drive adoption of test-driven development practices within engineering teams.

  • Mentor developers on testing best practices and help establish quality gates in the development process.

Who You Are

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

  • Proficient in TypeScript, with knowledge of Golang and Python a plus. (Strong skills in TypeScript are essential, while familiarity with Golang and Python is beneficial).

  • 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.

  • Based in Europe.
