Job description

*instinctools is a software development company that provides custom software solutions for businesses of all sizes. Our team works closely with clients to understand their specific needs and provide personalized solutions that meet their business requirements.

Our team is looking for a Senior Full-Stack QA Engineer for one of our clients.

Our customer

is a global mobility and urban services platform that allows users to book rides or other services and negotiate the fare directly with the service provider. It offers a variety of services including ride-hailing, intercity travel, delivery, and task assistance, operating in over 700 cities across 47 countries and is the second most downloaded mobility app in the world.

About the project:

This is a product delivery team responsible for the end-to-end passenger experience in a ride-hailing application. The scope covers the full passenger journey — from onboarding and order creation to tariff and driver selection, the in-ride experience, and post-ride interactions such as ratings, reviews, contextual trip updates, promos, and discounts. You will work on passenger-app features and an integration layer that connects downstream services to support the user experience. The tech context includes a microservices architecture, event-driven integrations, mobile feature delivery for driver and passenger apps, data analytics, and A/B testing.

Responsibilities and tasks:

• Design and maintain test cases / test suites for product features.
• Design, develop, and maintain automated test suites for APIs and mobile UI (iOS and Android).
• Implement shift-left testing practices.
• Build and maintain test frameworks and tools for QA engineers, integrate them into CI/CD pipelines. Ensure the reliability of testing infrastructure.
• Work with TechOps and other teams to implement quality management processes and improve testing workflows.
• Investigate production issues, perform root cause analysis, and collaborate with backend and mobile developers to prevent regressions.
• Track quality metrics in Jira/Tableau, automate routine tasks. Advocate for testability.

Our expectations of the candidate:

• 3+ years in Functional Testing. 3+ years in QA Automation. 1+ year in mobile app testing and automation.
• Recent hands-on experience with both functional and automated testing.
• Proficiency in API testing (Postman or similar), database operations (CRUD), and basic command-line tools (bash/zsh).
• Proficiency in mobile testing (iOS and Android, including emulators, traffic sniffing, and OS‑specific testing).
• Proficiency in Kotlin (or, alternatively, strong programming skills in at least one language: Python, Java, TypeScript).
• Solid understanding of mobile platforms, client‑server architecture, and network protocols.
• Experience with CI/CD tools (Jenkins, GitLab CI, GitHub Actions), version control (Git), and test management practices. Ability to read and reason about backend and frontend code to pinpoint defects accurately.
• Experience using AI-assisted development tools (GitHub Copilot, ChatGPT, Claude) to accelerate coding, testing, and code review workflows

Nice to have:

• Experience with contract testing (Pact) or visual regression testing for mobile.
• Experience with GraphQL and gRPC contract testing
• Highly proactive – ability to figure out who to reach out to and how to get things done independently.
• Stakeholder management – comfortable interacting with various stakeholders, from senior developers to product managers.
• Curious mindset – challenges existing processes and looks for continuous improvement.
• Strong communication – able to have project-related conversations with product managers and other team members.
• Time management – organized and reliable.

We offer:

• Work on one of the world’s largest mobility platforms, serving millions of users across 47 countries
• Direct collaboration with experienced product and engineering teams working on business-critical systems
• Flexible remote work within approved locations
• A real team, not a staffing bench: a collaborative environment, direct access to your delivery manager, and ongoing support throughout your work on the project
• Structured feedback and ongoing communication with both the project team and your delivery manager
• Professional and highly collaborative engineering culture focused on knowledge sharing and continuous improvement
• Learning and development are part of how we work: the company supports your growth and creates opportunities to explore new technologies
