Senior Full Stack Software Engineer

Description and Requirements
Role Value Proposition:
We're looking for a senior engineer who is passionate about engineering, excellence and developer experience. In this role, you will drive org-wide AI adoption, test automation strategy, and DevEx improvements, partnering with product teams to design reusable frameworks, platforms, and best practices that significantly accelerate delivery while improving quality and security.
You will act as a technical leader and hands-on builder-defining standards, building reference implementations, coaching teams, and instrumenting metrics to measure impact.
Key Responsibilities:

• Design and deliver AI-assisted development workflows (e.g., code generation, refactoring assistance, knowledge search, test generation) using tools like GitHub Copilot, Azure OpenAI, and M365 Copilot.
• Build AI services and integration patterns (e.g., prompt engineering libraries, retrieval-augmented generation, model evaluation, guardrails, observability).
• Optimize local dev environments and inner loops: fast builds, containerized dev, remote dev environments, golden paths, and templates.
• Build platform tooling: CI/CD pipelines, reusable GitHub Actions/Azure DevOps templates, standardized build/release workflows, and deployment automation.
• Improve repo hygiene: monorepo/multirepo strategy, branch protection, semantic versioning, conventional commits, and automated changelogs.
• Implement observability for DevEx: DORA metrics (lead time, deployment frequency, MTTR, change failure rate), build times, flaky tests, PR cycle time.
• Run productivity experiments and A/B tests (e.g., Copilot on/off, pipeline caching strategies) and scale what works.
• Define and implement test pyramids across unit, integration, contract, and end-to-end layers.
• Build and scale test automation frameworks (e.g., Playwright/Cypress/Selenium, REST API testing, Pact for consumer-driven contracts, performance testing with k6/JMeter).

Essential Business Experience and Technical Skills:
Required:

• 9+ years of professional software engineering experience with full-stack development.
• Proven track record in test automation frameworks, CI/CD pipelines, and developer productivity tooling.
• Strong proficiency in front-end (React, Angular, or similar) and back-end (Node.js, Java, .NET, or Python) technologies.
• Expertise in automated testing tools (Playwright, Cypress, Selenium, JUnit, PyTest) and contract testing (Pact).
• Hands-on experience with CI/CD platforms (GitHub Actions, Azure DevOps) and cloud environments (Azure preferred, AWS/GCP acceptable).
• Familiarity with AI-assisted development tools (GitHub Copilot, Azure OpenAI) and prompt engineering concepts.

Preferred:

• Familiarity with DORA metrics and productivity measurement frameworks.
• Exposure to microservices architecture, event-driven systems, and performance testing.
