Urgent! Software Engineer - Quality and Performance Job Opening In Krakow – Now Hiring IBM
**Introduction**
We’re building Astra Serverless, the next generation of distributed, scalable, fault-tolerant, serverless NoSQL data services — powered by Apache Cassandra and extended with native Vector and AI capabilities across multi-cloud environments.
Our customers depend on our platform to serve real-time, mission-critical workloads on a global scale.
Ensuring reliability, performance, and correctness under unpredictable workloads is a non-trivial challenge — and that’s where you come in.
As an engineer on the Quality Engineering and Performance team, you’ll develop and evolve the system-level testing frameworks that validate a distributed database-as-a-service at massive AI-driven workload scale.
You’ll help ensure that new features, performance improvements, and AI-driven extensions meet the highest standards of scalability and resilience.
Why this role?
You’ll work at the intersection of distributed systems engineering and test architecture — hands on designing and building automation and frameworks that simulate complex multi-cloud deployments, chaos scenarios, and performance stress conditions.
This is not QA-as-usual: you’ll engineer the test systems that validate an elastic database platform capable of scaling thousands of non-uniform nodes, self-healing under failure, and integrating real-time vector search and analytics.
If you thrive on deep technical challenges, curiosity, analytical and systems thinking, and building tools other engineers rely on, this role will feel like home.
**Your role and responsibilities**
* Design and develop frameworks for end-to-end and chaos testing of distributed, serverless Cassandra-based systems.
* Engineer automation that validates data correctness, fault tolerance, and performance under complex multi-region and -cloud topologies.
* Collaborate closely with your peers in local and remote feature development teams to model real-world scenarios and integrate automated validation into the delivery pipeline.
* Continuously evolve the test infrastructure for scale, speed, and observability — leveraging Kubernetes, Docker, and cloud-native toolchains.
* Profile and tune distributed workloads to uncover systemic bottlenecks and verify that service-level goals are consistently met.
* Contribute code to shared testing frameworks and participate in design and code reviews across teams.
* Own the full cycle of quality engineering — from test design and execution to insights and continuous improvement.
**Required technical and professional expertise**
* Exposure to system level Java and Python development in testing for distributed or cloud systems — replication, partitioning, consistency, and eventual convergence.
* Eagerness to learn more about and using chaos testing, fault injection, or resilience validation.
* Knowledge of analyzing complex logs and metrics to isolate performance and reliability issues.
*
Familiarity with Linux, Kubernetes, Docker, and CI/CD pipelines (Jenkins, GitHub Actions, etc.).
**Preferred technical and professional experience**
* Familiarity with NoSQL technologies (Cassandra, DynamoDB, ScyllaDB, etc.) and cloud platforms (AWS, GCP, Azure) and multi-cloud topologies.
* Curiosity-driven mindset, strong communication skills, and a focus on collaboration and craftsmanship.
* Understanding of vector search, AI embeddings, or data-intensive workloads.
