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

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

Hyderabad, India | Hybrid - 3 days onsite

Role Overview

Nasuni is expanding the DryvIQ engineering team in Hyderabad. DryvIQ brings intelligent content discovery, classification, sensitivity detection, and policy-driven governance to enterprise unstructured data across cloud and on-premises repositories.

We are looking for a  Senior Software Engineer in Test (SDET)  to strengthen and scale automated quality across DryvIQ's complex, Kubernetes-based distributed application environment.

This is a hands-on senior engineering role with a primary focus on C#/.NET test automation. You will maintain, extend, and improve existing automation frameworks, build high-value automated coverage, strengthen test infrastructure, and help automation scale as the DryvIQ platform evolves. You do not  need to have built an automation framework from scratch; what matters is demonstrated depth improving and scaling automation in a complex software environment.

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.
