Senior QA Engineer (Performance & Data Platforms)

Location: 100% Remote (Poland)Contract: B2B (via Entrada AI Poland)

ABOUT ENTRADA AI Entrada AI is a specialized consulting partner and a strategic portfolio company of Databricks Ventures. This is a rare distinction: Databricks invested in us because of our technical excellence, placing us in the "inner circle" of the ecosystem. For our engineers, this means direct access to product roadmaps, private previews, and the teams building the platform.

You will join a team of industry veterans and Databricks MVPs. We look for engineers who value clean architecture over quick fixes. We don't just maintain pipelines; we solve complex architectural challenges for Fortune 500 clients using features often before they are widely available.

THE ROLE

This is not a traditional QA role. You will be embedded directly into the client's Data Pipeline team (Staff Augmentation model), working toward a critical July 2026 product launch.

What You’ll Be Testing

You will be performance-testing a multi-tenant enterprise data platform, focusing on:

• API Layer: Load and stress testing of customer-facing Data Sharing APIs and data access endpoints.

• Authentication Flows: Throughput and concurrency testing of multi-tenant authentication and access control systems.

• Data Pipelines: Performance validation of data ingestion and delivery pipelines under enterprise-scale load.

• Data Isolation: Stress testing tenant data segregation logic to validate correctness and security under heavy concurrent load.

Requirements

• 5+ years in QA engineering with a heavy focus on performance testing.

• Hands-on expertise with tools like JMeter, Gatling, k6, or equivalent.

• Deep experience testing REST APIs at scale (this is a backend-centric role, not UI/functional).

• Familiarity with cloud data platforms (e.g., Databricks, AWS) – you need to understand the architecture of data platforms.

• Multi-tenant SaaS experience – understanding of data isolation, auth flows, and concurrent user scenarios.

• Strong scripting skills for automation (Python preferred).

• Fluent English – required for direct collaboration with an international engineering team.

Nice to Have

• Experience testing Databricks or Spark pipelines.

• Background in FinTech or financial data platforms.

• Proven track record of building performance testing frameworks from scratch.

THE OFFER

• Salary: 140-160/h

• Start: 07.04.2026

• Stable Employment: Contract signed with our Polish entity (Entrada AI Poland).

• 100% Remote: Full flexibility to work from anywhere in Poland.

• Apple Hardware: Macbook Air M4 15" provided.

• Referral Bonus: Bonus for bringing other top-tier engineers to the team.

• Professional Growth:

  • Databricks certification cost coverage.

  • Opportunity to present at industry conferences (building your personal brand).

  • Direct collaboration with Databricks MVPs and product teams.
