Principal Engineer, Test Automation

Overview

We are seeking a Principal Automation Engineer to define automation architecture, technical roadmaps, and engineering standards for API, UI, integration, and end-to-end testing. This hands-on role will lead scalable C#/.NET frameworks, establish CI/CD quality gates, guide cross-team adoption, and resolve complex automation and testability challenges across distributed products.

What you'll do

• Own the enterprise-grade automation architecture and roadmap for C#-based REST API, UI, integration, and workflow testing.
• Design modular frameworks with reusable libraries for configuration, service clients, page or component objects, test data, parallel execution, retries, logging, reporting, and environment management.
• Define coding standards, branching and review practices, framework governance, versioning, documentation, and contribution models.
• Establish pipeline strategy for pull-request validation, daily smoke tests, staged regression, release qualification, and automated quality gates.
• Guide teams on automation suitability, testability, coverage modelling, risk-based selection, and reduction of flaky or low-value tests.
• Lead technical reviews, proofs of concept, framework migrations, tool evaluations, and resolution of complex cross-service failures.
• Define dashboards and metrics for coverage, reliability, execution time, defect containment, failure causes, and productivity gains.
• Partner with architecture, software, DevOps, cybersecurity, systems, and verification leaders to embed quality throughout delivery.
• Mentor automation engineers and build engineering capability through reusable assets, coaching, and technical communities of practice.

What you'll need

• 10+ years of experience defining automation architecture, technical roadmaps, and engineering standards for API, UI, integration, and end-to-end testing.
• A systems-oriented Quality Engineer mindset with a strong understanding of how products, services, and components interconnect, the ability to see broader product architecture, and the ability to decompose requirements to capture use cases holistically.
• Hands-on Automation Architect experience with advanced C# and .NET skills and a strong understanding of software design principles, dependency injection, concurrency, asynchronous execution, and extensible architecture.
• Hands-on experience architecting and developing REST API automation frameworks using RestSharp.
• Strong hands-on experience with NUnit or Selenium or playwright for test automation.
• Working knowledge of GraphQL (GQL) and experience validating GraphQL APIs.
• Solid understanding of test data management principles, strategies, and reusable data provisioning approaches.
• Strong awareness of Kubernetes and containerized test environments.
• Good understanding of communication protocols, particularly SIP, and hands-on exposure to SIPp for protocol-level testing.
• Expertise in API contracts, distributed systems, microservices, event-driven integrations, databases, authentication, authorization, and service virtualization.
• Deep experience with Git, CI/CD architecture, parallel execution, automated reporting, and quality gates.
• Proven ability to improve framework reliability, diagnose flaky tests, optimize execution, and drive adoption across multiple teams.
• Strong technical leadership, stakeholder communication, mentoring, and architecture decision-making skills.
• B.E/B. Tech in Computer Science / Electronics & Communication / Electrical or related field.

Nice to have

• Experience with Allure reporting is preferred.
• Experience with Postman is good to have.
• Experience with Azure, Docker, infrastructure-as-code, message brokers, observability platforms, and cloud-native test environments.
• Experience validating healthcare platforms, HL7/FHIR integrations, connected devices, or regulated software products.
• Knowledge of security, accessibility, performance, reliability, and resilience testing within a unified automation strategy.
• Relevant Microsoft, cloud, architecture, or testing certification is advantageous.
• Knowledge of SIP infrastructure and media components such as Kamailio, FreeSWITCH, RTPEngine, SBCs, registrars, RTP, and WebRTC.
• Experience with Azure Key Vault, Azure App Configuration, Azure Cache for Redis, Azure Web PubSub, Terraform, KEDA, and container security tooling.
• Familiarity with IEC 62304, ISO 13485, risk management, cybersecurity expectations, and quality systems for regulated healthcare software.
• Experience with Jira, Jama, validated toolchains, Agile/Scrum delivery, and formal release-readiness reviews.
• Experience leading a team of automation testers toward a common goal.
