BloomReach is building an agentic platform for personalization, using AI to revolutionize how businesses connect with customers through autonomous search, conversational shopping, and autonomous marketing. The company powers personalization for 1,400+ global brands.
The Data Pipeline team is a backend-focused engineering group responsible for moving customers' data reliably at scale. The team processes tens of thousands of requests per second through real-time tracking, imports millions of rows of data continuously, and exports data to BigQuery using Google Cloud Platform and Kubernetes.
As a Quality Assurance Engineer II, you will own quality for systems that move huge volumes of customer data in real time across many integrations. You'll work in a backend, data-heavy environment with a tracking API, internal message formats, multiple storages, Kafka, GCP, and Kubernetes. Your responsibilities include:
• Design and own black-box, API-level, and integration/end-to-end test automation for Data Pipeline services, primarily in the imports domain
• Build and maintain automated test suites in CI/CD (GitLab) that gate deployments and catch regressions across components
• Read Go/Python pipeline code to find gaps and design meaningful test cases—you need to understand the system deeply
• Drive test strategy in grooming and design reviews, defining test types, acceptance criteria, edge cases, and failure modes on tickets before code is written
• Pair with the current Data Pipeline QA to spread automation and testing practices across the team
• Turn production incidents into durable, automated regression tests using telemetry and reproduction
You'll work with Python (primary), Go (to read code), Robot Framework for API/integration testing, GitLab CI, ReportPortal/Allure reporting, and AI coding agents like Cursor and Claude Code. You'll join an experienced Senior Quality Engineer already on the team and have a manager (Adam Zurek) who supports your growth. The team works remote-first from Central & Eastern Europe but has offices in Bratislava, Brno, and Prague if you prefer in-person collaboration.
QUALIFICATIONS
Must have:
• Write test automation in code—integration and API tests in CI using Python, Go, or similar languages
• Read backend/pipeline code (Go or Python) well enough to find gaps and reason about cross-component failures
• Own black-box, API, and integration/end-to-end automation (the outside-in layer)
• Work primarily in code and automation; if coming from manual testing, you must be excited to make automation your main craft
• Comfortable in grooming and design from day one with a shift-left mindset
• Ability to learn and adapt when navigating large codebases and data domains mixing tracking, imports, and multiple storages
• Effective in remote-first environments
• Fluent use of AI coding agents (Cursor, Claude Code, Copilot, Gemini CLI, or similar) as part of daily workflow
Strongly preferred:
• Prior backend exposure (internship or role writing code or working under a senior with proper testing/automation workflows)
• Experience with ETL/data-pipeline testing: connectors, ingest at scale, data cleanup, transformations, and validating data in target storages
• Experience testing systems built on Kafka, GCP, or BigQuery
• Familiarity with test frameworks such as Robot Framework, Playwright, or API testing tools (Postman and beyond)
Personal qualities:
• Ownership—you take quality from detection through to a durable, automated fix
• Systematic thinking—you find root causes and document learnings so the team levels up
• Collaboration—you make developers better at testing rather than becoming a handoff point
• Curiosity—you enjoy understanding what can go wrong in data pipelines and why
