Senior QA Engineer – API Testing

We are a global technology consulting company specializing in IT solutions, cloud-based platforms, mobile and web applications,

and training and support services. With over 14 years of experience and a multicultural team of more than 100 professionals, we

deliver projects for highly complex industries such as pharmaceuticals, diagnostics, healthcare, and consumer goods.

At our company, we value international talent, diversity, flexibility, and a collaborative environment that fosters both

professional growth and personal well-being.

At Nuvolar, we are looking for a Senior QA Engineer to join one of our healthcare projects, working on digital health solutions

that support complex workflows and critical software platforms.

You will become part of a technical team responsible for ensuring the quality of a platform that manages sensitive healthcare

information, integrations, and services within a complex digital health ecosystem.This role is a great opportunity for a QA

Engineer who enjoys understanding complex products, defining quality strategies, designing meaningful test scenarios, and

collaborating closely with developers and product teams to deliver reliable software.

As the first QA Engineer joining this product team, you'll have the opportunity to shape how quality is built into the product

from the early stages. Rather than joining an established QA function within the team, you'll define testing strategies, introduce

best practices, and help embed quality throughout the development lifecycle while working closely with developers and product

stakeholders.

• Define and execute the QA strategy for backend services, APIs, integrations, and critical product workflows.
• Understand the product domain and translate business requirements into effective test scenarios.
• Design, maintain, and execute test plans covering functional testing, regression testing, integration testing, exploratory

testing, and edge cases.

• Perform backend and API testing using tools such as Postman and OpenAPI/Swagger specifications.
• Validate REST APIs, data consistency, error handling, authentication flows, and integration scenarios.
• Work with relational databases such as PostgreSQL to validate data integrity and support testing activities.
• Contribute to test automation initiatives by maintaining and improving automated test suites.
• Analyse logs, traces, and system behaviour using monitoring and observability tools.
• Collaborate closely with developers, Product Owners, and technical stakeholders to identify risks early and ensure release

readiness.

• Drive continuous improvement of QA practices and help establish quality standards within the team.

• Proven experience as a QA Engineer working on software products, backend services, REST APIs, or integration-heavy platforms.
• Strong experience with API testing using Postman, Swagger/OpenAPI, or similar tools.
• Experience creating, maintaining, or improving automated test suites.
• Solid understanding of QA methodologies, test design techniques, regression testing, exploratory testing, integration testing,

and defect management.

• Experience working with relational databases and SQL to validate data integrity and application behaviour.
• Knowledge of cloud environments, ideally AWS, with a practical understanding of services such as DynamoDB, SQS/SNS, and Secrets

Manager.

• Experience working with GitHub and CI/CD workflows, ideally GitHub Actions.
• AI literacy, including familiarity with AI-assisted tools, AI agents, or the practical use of AI to improve testing,

automation, and documentation.

• Ability to understand complex technical environments, identify quality risks, and work collaboratively with developers and

product teams.

• Experience working in Agile/Scrum environments.
• Professional level of English, both written and spoken.

• Experience working in healthcare, digital health, medical software, or other regulated environments.
• Previous experience with patient data, identity management, or clinical workflows.
• Knowledge of Spring Boot, Java, Maven, or Java backend ecosystems.
• Experience with Playwright.
• Experience replacing or modernising existing automation frameworks.
• Experience with contract testing, distributed systems, or end-to-end integration testing.
• Experience with Docker and containerised development or testing environments.

• Flexible Work & Work-Life Balance: enjoy options to balance work and personal life, including every other Friday off.
• Remote Work: this is a fully remote position, giving you the flexibility to work from anywhere in Spain while staying closely

connected with your team.

• Seniority Program: enjoy additional benefits and privileges as you grow with the company.
• Social & Team Budget: even though we primarily work remotely, we encourage team gatherings and activities, with a dedicated

budget.

• Continuous Learning: access training, mentorship, and professional development opportunities.
• Growth Opportunities: participate in challenging healthcare technology projects, work with modern technologies, shape the QA

strategy of a growing product team, and contribute to the evolution of quality engineering practices.
