Senior Software Test Engineer

Overview

Software Test Engineer to build quality into Cortex development, a software value stream for semiconductor data workflows, and progressively establish an automated release-validation capability.

What you'll do

• Build and maintain automated end-to-end tests for Cortex's critical user journeys.
• Develop API and integration tests that validate service behavior, data flows, and interactions between components.
• Create and maintain a reliable regression suite that supports frequent development and releases.
• Test compatibility across Cortex Core, Contributor applications, plugins, and relevant user workflows.
• Define and improve test strategy, test design, and automation practices in collaboration with developers and product owners.
• Integrate automated tests into CI/CD pipelines and help establish quality gates for builds and releases.
• Support release validation by assessing test results, identifying risks, and communicating evidence-based recommendations.
• Track meaningful test coverage and quality metrics, using them to identify gaps and guide improvements.
• Investigate defects, reproduce issues, analyze logs and test evidence, and work with developers to identify root causes.
• Challenge ambiguous or incomplete requirements and help define clear, testable acceptance criteria.
• Advocate for customer and user needs, including usability and reliability across complex scientific workflows.
• Collaborate closely with developers throughout implementation so that testability and quality are considered early.
• Help improve test stability, execution speed, maintainability, and the signal-to-noise ratio of automated test results.
• Explore additional testing approaches, such as performance, contract, or distributed-system testing, where they address product risks.
• Learn the semiconductor domain and Cortex workflows, and test solutions in the environments used by the team, including virtual machines.
• Regularly reflect with the team on how to improve quality practices and delivery.

What you'll need

• Bachelor's or master's degree in computer science, software engineering, computer engineering, or a related technical field, or equivalent practical experience.
• Professional experience in software testing, test automation, or quality engineering.
• Experience designing and implementing automated end-to-end tests using Cypress, Playwright, or a comparable framework.
• Experience with API testing and integration testing.
• Proficiency in TypeScript, Python, or an equivalent language used for test automation.
• Experience integrating automated tests into CI/CD pipelines.
• Strong test-design skills, including the ability to identify risks, select effective coverage, and build maintainable regression automation.
• Experience investigating defects and working with developers to determine root causes.
• Strong attention to detail and a curious, investigative approach to problem-solving.
• Ability to understand software from the customer and user perspective and challenge unclear requirements constructively.
• Strong collaboration and communication skills, with a commitment to quality across the development lifecycle.
• A sense of ownership and the ability to make data-informed recommendations about product quality and release readiness.
• Excellent written and spoken English.

Nice to have

• Testing applications deployed to Kubernetes or other containerized environments.
• Performance or load testing.
• Testing .NET services or Angular applications.
• Contract testing or testing distributed systems.
• Experience validating plugins, extensible applications, or integrations across independently developed components.
• Familiarity with scientific software, imaging, data-intensive applications, or semiconductor workflows.
• Experience working in a distributed, cross-functional Agile team.
