Job description

Senior Quality Assurance Engineer

Department: AssetOps Engineering

Employment Type: Permanent

Location: Madrid

Description

Assets Ops is part of the osapiens HUB platform's Efficiency suite, helping enterprise customers manage maintenance, facilities, and operational workflows at scale. As a Senior Quality Engineer embedded in the Assets Ops team, you will own the quality strategy end-to-end — from defining testing approaches to shipping and maintaining automation frameworks that keep the product stable and reliable for thousands of users.

You will work side by side with developers, product managers, and business stakeholders to embed quality throughout the development lifecycle, not just at the end of it. That means fast feedback loops, meaningful test coverage, and a clear-eyed view of product health at all times.

You will be working in a hybrid work setup, with a collaborative and international team. You'll join a fast-growing company at the intersection of AI, compliance, and enterprise software — where the quality of what you ship genuinely matters to the customers relying on it.

What you’ll do

Quality strategy & ownership

• Define, implement, and continuously improve testing strategies in close alignment with the product and engineering teams.
• Serve as the team's subject matter expert on QA processes, tooling, and best practices — raising the bar for the whole squad.
• Maintain clear, accurate, and actionable test documentation and reporting for both developers and business stakeholders.

Hands‑on testing

• Test newly implemented features using a diverse range of testing techniques, with a focus on uncovering gaps early.
• Perform exploratory testing to proactively identify regressions and edge cases before they reach production.
• Provide fast, reliable feedback on product health and stability to developers and stakeholders throughout each sprint.

Automation & tooling

• Develop, execute, and maintain automated test suites covering E2E and API testing for both web and mobile applications.
• Perform root-cause analysis on failing automated tests and drive their resolution.
• Set up and maintain CI/CD pipelines to ensure continuous quality gates are in place (Azure DevOps preferred).
• Contribute to AI-assisted development efforts and explore how emerging tooling can improve the team's quality workflows.

Collaboration & communication

• Report bugs clearly and follow up on their resolution, monitoring the bug backlog to keep it actionable.
• Support developers in investigating and reproducing issues, acting as a trusted partner rather than a gatekeeper.

Your Responsibilities

• Test the products applying diverse testing techniques to uncover bugs.
• Report bugs and follow up their resolution.
• Develop new and maintain the existing automated end-to-end and API tests.
• Contribute to AI-assisted development efforts and tooling.
• Setup and maintain CI/CD pipelines.
• Perform root-cause analysis of failing automated tests.
• Provide the developers and business representatives with fast feedback regarding the current state of the product.
• Assist and help the developers in investigating issues.

Your Experience

What you bring

Must-haves

• 6+ years of experience testing web-based applications.
• 4+ years of experience in test automation using JavaScript or TypeScript — ideally with Playwright.
• Solid hands-on experience in both E2E and API testing and automation.
• Proven experience setting up and maintaining CI/CD pipelines (Azure DevOps preferred).
• Strong root-cause analysis skills and the ability to diagnose flaky or failing tests independently.
• Excellent written and spoken English.

How you work

• Autonomous and accountable — you take ownership of your work and deliver it with care.
• A proactive team player who communicates clearly and keeps stakeholders in the loop.
• Critical thinker who questions assumptions and advocates for the right level of quality.

Nice to have

• Exposure to AI-assisted development tools and workflows.
• Experience testing mobile applications (native or hybrid).
• Familiarity with the enterprise SaaS or supply chain compliance domain.
