Senior Software Engineer in Test | Cloudera DataFlow (CDF) Quality Assurance

Cloudera

Budapestsenior

Apply on the employer's site

Role description

Business Area:
Engineering

Seniority Level:
Mid-Senior level

Job Description:
At Cloudera, we empower people to transform complex data into clear and actionable insights. With as much data under management as the hyperscalers, we're the preferred data partner for the top companies in almost every industry. Powered by the relentless innovation of the open source community, Cloudera advances digital transformation for the world’s largest enterprises.

The Mission: Engineering Resilience for Cloudera Data Flow (CDF) to Run Anywhere

Data is dynamic, and your processing services must be just as agile. As a Senior Software Engineer in Test on the Cloudera DataFlow team, you will be on a critical mission to ensure the quality, reliability, and deployment of our next-generation data service, Cloudera DataFlow (CDF). You will participate in and drive the testing strategy for the entire CDF platform.

This critical service must be rigorously tested to be capable of running anywhere, from fully air-gapped, on-premise servers to the most complex public cloud environments.

We are advancing a massive-scale platform. If you are obsessed with designing and executing highly reliable, distributed data flow systems testing that ensures efficient, scalable workloads across any environment, this is your perfect opportunity.

This role is not eligible for immigration sponsorship or relocation.
The Impact You’ll Make

  • Testing & Quality Assurance: You will be responsible for enhancing and maintaining our existing CI/CD pipelines and Java-based automated test suites, working with modern, Kubernetes-based test infrastructure. Your goal is to transform these assets into an advanced validation engine, crucial for the swift and dependable release of Cloudera Data Flow, thereby owning the Testing & Quality Assurance domain.
  • Technical Expertise & Troubleshooting: Become a subject matter expert in data flow management. When distributed systems fail at scale, you lead the charge. You will perform deep-dive troubleshooting and Root Cause Analysis on complex, system-level failures that only emerge in high-throughput environments.
  • Bake-In Excellence: You will work synchronously with the broader engineering team to bake quality into the code from day one, ensuring that testability is a first-class citizen in our software design.

Your Technical DNA

  • Bsc/Msc in related field or equivalent experience
  • Java Proficiency: You write clean, performant code and understand the nuances of the Java ecosystem in a distributed context.
  • Kubernetes & Docker Mastery: You treat containerization and orchestration as the foundation of modern deployments. You know how to simulate complex cluster failures to test system limits.
  • Validation Architect: You have a proven track record of designing complex test plans and automated methodologies that integrate seamlessly into robust CI/CD pipelines.
  • Testing & Development: Familiarity with diverse test frameworks (e.g., JUnit, TestNG, Mockito) for various testing levels, and practical experience developing and debugging software in Linux environments.
  • Communication: Excellent professional proficiency in written and spoken English, essential for clear documentation and seamless collaboration within distributed teams.

What Makes You Stand Out

  • Data flow management experience: You’ve worked with Apache NiFi or similar engines and understand complex data flow pipelines.
  • Cloud & Infrastructure: You’ve deployed to AWS, Azure, or GCP and have used Ansible or Terraform to treat "Infrastructure as Code" as a creative discipline.
  • The "Quality First" Mindset: You have a passion for building tools that break things so that our customers never do.
  • Hands-on experience with Python is considered an advantage.

What you can expect from us:

  • Generous PTO Policy
  • Support work life balance with Unplugged Days
  • Flexible WFH Policy
  • Mental & Physical Wellness programs
  • Phone and Internet Reimbursement program
  • Access to Continued Career Development
  • Comprehensive Benefits and Competitive Packages
  • Paid Volunteer Time
  • Employee Resource Groups
