Description
The employer is the IT and digital unit of a large retail group, running infrastructures for its retail divisions and acting as an independent provider of cloud, cyber security, data & AI, communication and workspace services across Europe. The IaaS domain owns the compute, storage and networking primitives on which customers run their workloads, and validating a cloud platform of this scale is a complex distributed-systems engineering challenge rather than a classic QA job. The role sits at the interface of agility and security, designing test architecture, testing frameworks and backend tooling that IaaS teams use to validate their code. The mission is to build the automated foundation proving the infrastructure runs reliably and can be safely deployed to production at any time.

Responsibilities
Design, implement and operate a holistic test strategy across all IaaS products covering unit, integration, staging/smoke, production (live), acceptance, configuration, disaster-recovery and performance testing
Develop robust, reusable automated test primitives and scaffolding for OpenStack, Kubernetes, distributed API backends and middleware
Integrate automated test reporting deeply into development and release workflows so every code change is automatically verified and gated before production deployment
Shift test execution earlier in the development lifecycle and dependency chain while improving pipeline performance and maximizing meaningful code coverage
Find bugs before they reach the staging environment and validate the performance limits of infrastructure components under load
Requirements
Comprehensive senior-level experience as a Software Architect, Platform Engineer or Backend Developer designing complex, highly distributed systems or cloud environments
Natural feel for system testability, robust CI/CD pipeline design and treating Infrastructure-as-Code as a first-class citizen
Excellent programming skills in Golang or Python for building backend tools and automation frameworks
Practical expertise in testing backend systems, ideally with a focus on Linux, Kubernetes, OpenStack and complex REST/gRPC APIs
Proven track record in designing scalable systems and validating high-performance backend components through benchmarks, profiling and stress tests
Conditions
Full-time employment
Fast decision-making paths and real creative leeway in projects
Stable foundation of a large corporate group behind the work
