Architect the testing infrastructure, tooling, and possibly add new types of tests (load tests, data-pipeline tests, resilience / fault-tolerance tests, etc.).
Design, implement, and maintain comprehensive automated test suites covering web front-ends, backend services, APIs, inter-service communication, data ingestion and processing pipelines, and storage layers.
Cover and test service-to-service communication (e.g., microservices, APIs, RPC calls), including modern protocols such as gRPC, and event-driven / messaging workflows (e.g., using Kafka), because AVILOO’s architecture may include distributed components, data streaming, and asynchronous workflows.
Automate end-to-end, integration, regression, and performance tests — especially for data-heavy flows (battery data ingestion, real-time monitoring, analytics).
Validate data correctness and database behavior: write SQL tests, queries, assertions against PostgreSQL (or whichever relational store is used) to ensure data integrity.
Collaborate closely with developers, DevOps (or infrastructure) engineers, and product owners to define testable requirements, CI/CD pipelines, and quality gates.
Participate in code reviews of test code, ensuring maintainability, readability, and best practices.
Monitor test results, log failures, define metrics for test coverage, reliability or performance regressions; report issues and work with devs to triage and fix.
Help design and implement automated CI/CD workflows — integrate tests into pipelines so that new changes are validated automatically, maintaining high quality and preventing regressions in a fast-paced environment.
Dein Profil
English speaking

Familiarity with version control (e.g. Git), branching workflows, code reviews.
Comfortable working as part of a cross-functional, international, team in an ambitious, high-growth startup/scale-up environment.
Experience with CI/CD tools and workflows — e.g. Jenkins, GitLab CI, GitHub Actions, or similar.
Familiarity with containerized environments (e.g. Docker), or infrastructure-as-code / deployment automation.
Experience with data-streaming, large-scale data ingestion / analytics systems; knowledge of monitoring/logging tools.
Exposure to cloud platforms / distributed compute / microservices.
Interest or prior experience in automotive, e-mobility, battery diagnostics, or embedded-to-cloud systems.
