Keyfactor is the leader in trust infrastructure for AI and machines, helping the world's largest enterprises and government agencies take control of the cryptographic identities that safeguard every digital interaction. Behind the platform is a integral team of people who care deeply about the work and each other. We move fast, think big, and show up for one another every day.

Title: Senior Software QA Analyst Barcelona (Hybrid work model) Experience: Mid - Senior Job Function: Engineering Employment Type: Full-Time In 2019, Keyfactor decided to widen its investment and acquired Redtrust, a Spanish company pioneer in the management of people’s identity through the custody and management of digital certificates. Redtrust has a strong reputation for providing top-notch products and services in Spain. As a Senior Manager, you’ll be a key member of the engineering team and will develop & maintain Redtrust products.

The Senior

Software QA Analyst is the quality-strategy owner for Redtrust — Keyfactor’s digital-signature and certificate-management platform. This is a senior individual-contributor role for someone who leads with test strategy and cross functional coordination, not just execution. You will take ownership of how Redtrust is tested end to end: defining risk-based test strategy, transforming a largely manual regression process into a prioritized, automation-first approach, and owning the interface between Product, Development, and QA so that quality is designed in early rather than inspected at the end. they build the automation — and partner with Development to grow the right test coverage at the right layer (unit, API, and UI).

This role is central to modernizing our testing practices and improving coordination across Product, Development, and QA. A shared, documented definition of "critical path", agreed with Product and Development, that drives what gets tested and at which layer. A healthier testing pyramid taking shape — a growing unit-test base owned by Development,



integration/API coverage owned by QA, and UI end-to-end testing focused on genuinely critical journeys — with you owning the boundary negotiations that make that shift real.

Quality risk made visible to leadership: regression cost, untested-surface exposure, and coverage trends quantified and reported to support planning. Design and own a comprehensive, risk-based test strategy for Redtrust, spanning functional, regression, integration, and end-to-end testing. Lead the transformation of a largely manual regression process into a prioritized, automation-first approach: inventory and risk-tier existing coverage, retire redundant and low-value cases, and drive a prioritized automation backlog to completion with the automation engineers.

Design and maintain test plans and test cases for significant product features, ensuring thorough, risk-appropriate coverage. Participate in product design and refinement reviews to surface quality and testability risks early ("shift-left"). Own the coordination interface between Product, Development, and QA — aligning the three functions on testing requirements and on which layer should catch which class of issue.

Partner with Development to define and grow the unit-test layer and agree the dev/QA testing boundary, prioritizing the platform’s most critical modules (e.g. signing and authentication). Establish and maintain test documentation, quality metrics, and reporting; make quality risk and progress visible to engineering leadership. Drive continuous improvement in QA methodologies, tooling, and process, including safeguards that prevent regression scope from re-bloating as the product grows.

Mentor junior QA engineers and share QA best practices across the team. Bachelor’s degree in Computer Science, Engineering, or a related field. ~5+ years of experience in QA engineering, QA analysis, or a related field. ~ Demonstrated experience with risk-based test strategy — able to assess a large or bloated test suite and defensibly prioritize, rationalize, and reduce it, not merely execute it. ~
