Position:
Senior SDET — Data Platform / Query Engine
Company:
KaaIoT
Compensation:
$4500
Location:
Europe (EU / EEA / UK), remote
Employment type:
Long-term contract
Work Arrangement:
EU business hours, shifted 2–3 hours later to ensure daily overlap with US West Coast (PST/PDT) mornings
Short Summary:
We are looking for a Senior SDET to lead the design of automated test frameworks and testing strategy for a large-scale distributed data platform. This role focuses on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.
Responsibilities:
- Architect, design, and evolve automated test frameworks in Python / pytest for backend services, REST APIs, and distributed data components.
- Define testing strategy for new features and platform components — coverage, risk assessment, and quality gates.
- Own end-to-end, integration, performance, and regression testing covering SQL query execution, data correctness at scale, and platform APIs.
- Lead performance and load testing efforts with JMeter, including workloads over JDBC / ODBC / Arrow Flight drivers.
- Design and validate large-scale data testing scenarios — query plans, result correctness across heterogeneous data sources, metadata consistency, and behavior under high concurrency.
- Own CI/CD test pipelines in Jenkins — architect, maintain, and continuously improve.
- Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker; drive automation and reproducibility.
- Investigate complex, cross-layer failures and drive root-cause analysis with engineering.
- Mentor middle SDETs, review test designs, and set quality standards across the team.
- Partner with US-based development leads on shift-left practices, testability, and release readiness.
Requirement:
- Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
- Programming: Strong proficiency in Python, including pytest, with deep understanding of OOP, software design principles, and test framework architecture.
- SQL & Data: Advanced SQL skills and strong understanding of relational and analytical data systems, including query execution internals.
- Data-intensive testing experience: Demonstrated experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases.
- Testing experience: 5+ years in backend/system test automation, with demonstrated ownership of test strategy and infrastructure.
- CI/CD & DevOps: Solid experience architecting and maintaining Jenkins pipelines and test environments.
- Containers & Orchestration: Strong working knowledge of Docker and Kubernetes.
- Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure).
- Version Control: Confident with Git / GitHub workflows and code review practices.
- English: Upper-Intermediate or higher (B2+).
- Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time.
- Leadership: Prior experience mentoring engineers, defining test strategy, or leading a QA/SDET function.
Benefits:
- Not specified.
