The Opportunity

We are seeking a Senior Software Test Engineer to lead verification and validation efforts across our cloud, web, and mobile platforms within a regulated medical device environment. This role is based in our hub in Barcelona, Spain, and plays a critical role in ensuring product quality, regulatory compliance, and scalable delivery across our digital health ecosystem.

This is an exciting opportunity for someone with deep experience in software verification, quality engineering, and test automation who is passionate about building quality into the software lifecycle and enabling teams to deliver high-confidence releases.

What you’ll do

• Lead end-to-end software verification and validation activities across cloud, web, and mobile platforms.
• Translate product, system, and technical requirements into effective manual and automated test strategies, plans, and cases.
• Design, build, and scale robust test automation frameworks across API, web, and mobile layers.
• Drive an automation-first testing approach by identifying automation opportunities and improving coverage, reliability, and execution speed.
• Integrate automated testing into CI/CD pipelines to support fast, reliable, and scalable software delivery.
• Ensure traceability between requirements, risks, and test cases in alignment with regulated development practices.
• Define and execute functional, integration, system, and regression testing strategies.
• Develop and maintain verification artifacts, including plans, protocols, and reports, in compliance with FDA 21 CFR, ISO 13485, IEC 62304, and related standards.
• Support risk management activities including defect triage, impact assessments, and root-cause investigations.
• Partner closely with engineers, product managers, architects, and quality teams to ensure requirements are testable and quality is embedded early in the development lifecycle.
• Participate in design reviews to verify that design inputs and outputs meet quality and regulatory expectations.
• Mentor other engineers on automation best practices, engineering discipline, and continuous improvement across testing frameworks, tools, and processes.

Required Qualifications

• Bachelor’s degree in software engineering, Computer Science, or a related field, or equivalent practical experience.
• 6+ years of experience in software test engineering, verification, or quality engineering.
• 2+ years of experience in regulated software development environments such as medical devices, digital health, or similar industries.
• Strong expertise in software verification and validation, including defect management, requirements traceability, and risk-based testing.
• Demonstrated experience designing and implementing automated testing across API, web, mobile, or similar platforms.
• Experience working within modern CI/CD ecosystems such as GitHub Actions, Azure Pipelines, or similar tooling.
• Strong programming or scripting skills in languages such as Python, JavaScript, or TypeScript for test automation and tooling.
• Excellent analytical, communication, and documentation skills, with a collaborative and quality-focused mindset.

Preferred Qualifications

• Experience in medical devices or other regulated environments.
• Hands-on experience with frameworks such as Playwright, Cypress, REST Assured, Jest, or similar tools.
• Experience with BDD automated testing and integration with Jira test management tools such as Xray or Zephyr.
• Understanding of cloud-native systems, APIs, microservices, and distributed architectures.
• A builder mindset, with the ability to continuously improve frameworks, tooling, and quality processes.
• Exposure to compliance standards such as HIPAA and GDPR.
• Experience with end-to-end testing involving both software and connected hardware components.
