Software QA Engineer

Job description

ABOUT US At TOPPAN Security, our mission is to shape a meaningful, technology-driven future by being a global leader in mission-critical identity and payment technologies. We serve as the international development arm of the TOPPAN Group in the security domain founded in 1900. TOPPAN is a trusted Japanese brand renowned for its commitment to exceptional quality. Building on this legacy, we combine bold ideas, deep sector expertise, and collaborative intelligence to deliver secure, future-ready solutions. Our culture is grounded in four core values: Agility , Ownership , Resilience , and a Sense of Fun . We move fast, lead with accountability, grow through challenges, and bring positive energy into everything we do. Join us and be part of a global, collaborative team where trust and innovation drive everything we do. ABOUT THE ROLE We are looking for a full-time Software QA Engineer with 3–5 years of hands-on experience to take end-to-end ownership of quality assurance across our products. You will own the testing strategy from the ground up — defining test cases and golden paths, building and maintaining automation, and validating functionality, performance, and business logic across both frontend and backend services. This is a hands-on role for someone who can work independently, set the QA bar for the team, and keep it well documented. Key Responsibilities • Own the QA process end to end — from test planning and case design through execution, automation, and sign-off. • Define test cases, golden paths, and acceptance criteria in collaboration with product and engineering teams. • Design, build, and maintain automated test suites for frontend and backend services. • Perform functional testing of frontend UI flows and backend service/API behavior. • Design and execute load and performance tests to validate system behavior under expected and peak traffic. • Develop and run business case / end-to-end scenario tests that reflect real-world usage of the product. • Identify, document, and track defects clearly, working with engineering to drive them to resolution. • Maintain clear, up-to-date test documentation, including test plans, test case libraries, and golden path references. • Integrate automated tests into CI/CD pipelines to support continuous testing. • Collaborate closely with developers, product managers, and DevOps to understand requirements and assess risk areas. • Continuously improve QA processes, tooling, and coverage as the product and architecture evolve. Required Skills & Experience • 3–5 years of professional, hands-on experience in software QA / test engineering. • Proven ability to independently own QA and testing strategy for a product or service, not just execute predefined scripts. • Strong experience designing test cases, test plans, and golden paths, with clear supporting documentation. • Hands-on experience testing frontend applications (UI/UX flows, cross-browser behavior, functional correctness). • Hands-on experience testing backend services and APIs (functional, integration, and regression testing). • Experience with test automation frameworks and tools for both frontend and backend testing. • Experience designing and running load and performance tests and interpreting the results. • Ability to design and execute business case / scenario-based tests that validate real user and system workflows. • Comfortable working with Git for version control of test code and test assets. • Familiarity with microservices architecture and how it affects test strategy and environments. Nice to Have • Experience testing systems built on C#/.NET and/or Java/Spring Boot backends, and Next.js frontends. • Familiarity with PostgreSQL for test data setup, validation, and query-level checks. • Experience testing services running in containerized/Kubernetes (K8s) environments. • Exposure to observability tools such as Grafana, Prometheus, and Loki to support performance testing and defect triage. • Comfortable working in a Linux environment. • Experience integrating automated tests into CI/CD pipelines. Soft Skills & Other Requirements • Strong ownership mindset — able to define and drive the QA process rather than simply following a script. • Excellent teamwork, communication, and collaboration skills, working closely with developers and product teams. • Fluency in English, spoken and written. • Strong attention to detail with a methodical, structured approach to testing. • Good written communication skills for producing clear test documentation and defect reports. • Ability to prioritize and manage testing effort across multiple features and deadlines in a fast-paced environment. What We Offer • Full ownership of the QA function with the autonomy to shape testing strategy and standards. • The opportunity to work across the full stack — frontend, backend, and infrastructure — within a modern microservices architecture. • A collaborative engineering culture with room for professional growth.
