(Senior) Test Architect, Cloud Infrastructure - STACKIT (m/f/d)

Schwarz Digits; Friedrichshall; Vor Ort; EUR 90.000 - 130.000; Vollzeit

Zusammenfassung

Schwarz Digits seeks a highly experienced Software Architect/Backend Engineer to design and build automated testing foundations for our IaaS platforms. You will shape testing across unit to production, develop OpenStack and Kubernetes tooling, and integrate tests into CI/CD workflows to ensure reliable, scalable infrastructure.

You will lead architecture discussions, champion testability, and drive performance and resilience in distributed systems, using Golang or Python for backend tooling.

Qualifikationen

• Extensive senior-level experience as Software Architect, Platform Engineer, or Backend Developer.
• Advocate for system testability, robust CI/CD pipelines, and infrastructure-as-code as a first‑class citizen.
• Excellent programming skills in Golang or Python for building custom backend tooling.
• Hands-on testing backend systems with Linux, Kubernetes, OpenStack, and REST/gRPC APIs.

Aufgaben

• Design, implement, and govern a holistic testing strategy across IaaS products.
• Build reusable automated test primitives for OpenStack, Kubernetes, and distributed backends.
• Deploy automated test reporting into development and release workflows.
• Restructure test execution to shift testing earlier in the lifecycle and improve pipeline performance.
• Catch defects before staging and validate performance of infrastructure components under load.

Jobbeschreibung

Introduction text

Schwarz Digits creates the technological foundation for digital sovereignty in Europe. As the IT and digital division of the Schwarz Group, we develop and manage the IT infrastructures for the retail divisions Lidl and Kaufland, as well as Schwarz Production and PreZero. At the same time, we operate as an independent provider in the external market to support companies across Europe in their digital transformation. We bundle our core services in the areas of Cloud, Cyber Security, Data & AI, Communication, and Workspace.Join us and contribute to digital sovereignty in Europe. With us, you will work at the intersection of agility and security: You will benefit from fast decision-making processes, enjoy genuine creative freedom in your projects, and be able to build upon the stable foundation of the Schwarz Group.

The IaaS domain owns the compute, storage, and networking primitives our customers run their workloads on. Validating a cloud platform at this scale is not a traditional QA job. It is a complex distributed systems engineering challenge.

We are looking for a highly experienced Software Architect or Backend Engineer who is passionate about developer experience, CI/CD, and system reliability. Rather than just writing test scripts, you will design the architecture, build the testing frameworks, and engineer the backend tooling that our IaaS teams use to validate their code. Your mission is to build the automated engineering foundation that proves our infrastructure is highly reliable, performant, and safe to deploy to production at scale.

Your Tasks

• Design, implement, and govern a holistic testing strategy across all IaaS products encompassing unit, integration, staging/smoke and production (live) testing, acceptance, configuration, disaster recovery, and performance testing.
• Build robust, reusable automated test primitives and scaffolding specifically for OpenStack, Kubernetes, distributed API backends and middleware.
• Deploy automated test reporting into our development and release workflows. Ensure every code change is automatically verified and gated before it can be deployed to production.
• Restructure test execution to shift testing earlier in the development lifecycle and dependency chain. Improve pipeline performance while maximizing meaningful code coverage.
• Catch defects before they reach staging, and validate the performance limits of our infrastructure components under load.

Your Profile

• You have extensive, senior-level experience as a Software Architect, Platform Engineer, or Backend Developer designing complex, highly distributed systems or cloud environments.
• You might not have held a "Test" title before, but you are the engineer on the team who naturally advocates for system testability, architects robust CI/CD pipelines, and treats infrastructure-as-code as a first-class citizen.
• You have excellent programming skills in Golang or Python for building our custom backend tooling and automation frameworks.
• You bring deep, hands‑on expertise in testing backend systems, ideally targeting Linux, Kubernetes, OpenStack, and complex REST/gRPC APIs.
• You have a proven track record of designing systems for scale, with an understanding of how to benchmark, profile, and stress‑test high‑performance backend components.
