Senior Software Engineer in Test — C#.NET Distributed Systems

You'll work across APIs, integrations, distributed and asynchronous workflows, containerized deployments, and user-facing functionality. Python and PyTest experience is valuable as we expand reusable tooling and cross-team libraries, but C#/.NET is the primary technical stack for this role .

This role is for an engineer who approaches quality as a software-engineering problem , applying strong coding, debugging, systems thinking, and test-design judgment rather than focusing only on test execution.

What You'll Do

• Maintain, extend, and scale existing C#/.NET-based test automation frameworks supporting DryvIQ.
• Design and implement reliable automated validation across API, integration, system, UI, regression, and end-to-end testing layers.
• Improve framework architecture, reusable components, test utilities, test-data capabilities, diagnostics, reporting, and maintainability.
• Build automated testing for Kubernetes-based, containerized, distributed applications, including multi-service and asynchronous workflows.
• Identify automation gaps, product risks, flaky tests, and framework limitations and prioritize improvements based on engineering and release impact.
• Build automated validation for APIs, microservices, distributed processing, asynchronous jobs, cloud and on-premises repositories, connectors, and enterprise integrations.
• Validate installation, deployment, configuration, upgrade, recovery, and failure scenarios in containerized environments.
• Integrate automated validation into CI/CD pipelines and improve the speed and quality of release feedback.
• Diagnose complex failures using application logs, APIs, Kubernetes/container evidence, telemetry, exceptions, service behavior, and other system evidence.
• Partner with developers to improve testability and determine the appropriate balance of unit, API, integration, system, and end-to-end coverage.
• Create maintainable automation patterns and reusable libraries that can be adopted by developers and QA engineers.
• Contribute to Python/PyTest-based utilities, tooling, or shared libraries as cross-team automation capabilities evolve.
• Help QA teammates strengthen automation skills through pairing, code reviews, examples, and technical guidance.
• Use approved AI-assisted engineering tools where appropriate for test design, code generation, scenario discovery, debugging, and coverage analysis, while independently validating generated outputs.
• Develop appropriate testing and validation approaches for AI-assisted or non-deterministic functionality.

Qualifications

Must-Have

• 6+ years of software engineering, SDET, test automation, or quality engineering experience with substantial hands-on automation development.
• Strong hands-on programming and test automation experience using C# and .NET.
• Demonstrated experience maintaining, extending, troubleshooting, and scaling an existing test automation framework.
• Experience improving framework reliability, maintainability, reusable components, utilities, test infrastructure, or execution efficiency.
• Strong hands-on experience testing Kubernetes-based, containerized, distributed applications.
• Strong understanding of Kubernetes, containers, distributed-system behavior, service dependencies, asynchronous processing, and failure modes.
• Experience building automated validation across APIs, integrations, systems, and end-to-end workflows.
• Experience testing microservices, asynchronous processing, or comparable distributed workflows.
• Experience integrating automated testing into CI/CD pipelines.
• Ability to diagnose complex failures using logs, APIs, application exceptions, Kubernetes/container evidence, telemetry, and system behavior.
• Strong judgment about what to automate, at which testing layer, and when manual or exploratory testing provides greater value.
• Strong collaboration skills working with software engineers, Product, DevOps, and QA peers.

Preferred

• Hands-on experience with Python and PyTest, particularly for test utilities, reusable libraries, tooling, fixtures, or cross-team automation.
• Experience working in engineering environments where C#/.NET and Python-based automation coexist.
• Experience creating reusable automation components or shared libraries used across teams.
• Playwright, Cypress, Selenium, or comparable UI automation technologies.
• AWS and/or Azure experience.
• AKS, EKS, K3s, or comparable Kubernetes environments.
• Cloud and on-premises connectors and storage integrations.
• SMB/NFS, S3, Azure Blob, or comparable enterprise data technologies.
• Postgres, ClickHouse, Keycloak, OAuth/OIDC, or similar technologies.
• Performance, load, reliability, resilience, or failure-injection testing.
• Test-data and test-environment architecture.
• Practical use of AI-assisted software or test-engineering tools with disciplined validation of generated outputs.

Ideal

• Significant experience improving automation for a complex product previously dependent on manual regression.
• Experience evolving an established automation framework as product scale, architecture, or engineering requirements changed.
• Strong experience testing distributed C#/.NET applications.
• Enterprise storage, content management, data governance, security, or data-infrastructure experience.
• Experience building reusable automation capabilities adopted across engineering or QA teams.
• Experience helping manual QA engineers become productive automation contributors.
• Experience testing large-scale distributed enterprise applications.
• Experience validating AI-enabled or non-deterministic functionality.
