QA Engineer (Application Support)

We are looking for QA Engineer (Application Support)

3+ Years of Experience in manual testing and application support. Experience in Automation is a PLUS!!
9am-6pm Hybrid work (3 days on-site in office at Ploenchit)

We are looking for a QA Engineer who combines hands-on functional testing with application support and production issue investigation for our Insurance Core Platform, covering Motor and Property lines across the Quotation, Renewal, and e-Policy modules. The platform is a web application built on Java (Spring Boot and/or Java EE) with an Angular or Vue.js frontend, backed by an Oracle database with substantial business logic in PL/SQL.

You will be the person who can take a defect or a production incident — a premium that calculated wrong, a renewal that did not generate, an e-Policy document that failed to issue — and trace it through the application, API logs, batch job output, and the Oracle database to isolate the root cause, then turn it into a clear, evidence-backed ticket for engineering and verify the fix end to end.

This is a delivery role in a regulated insurance environment: evidence quality, data handling discipline, and traceability are part of the job, not an afterthought.

 Responsibilities:

Quality Assurance

• Design and execute functional, regression, and UAT test cases across Quotation, Renewal, and e-Policy flows for Motor and Property products, covering the Angular/Vue web UI and the Java service layer behind it.

• Perform API-level testing (Postman or equivalent) against backend services, including negative cases, error contracts, and data validationPerform functional, integration, regression, and exploratory testing.

• Verify data outcomes directly in Oracle with SQL — policy records, transaction statuses, premium components, and document generation states across the policy lifecycle

• Maintain test documentation aligned to Definition of Ready / Definition of Done, with evidence suitable for audit (screenshots, logs, SQL results)

• Collaborate with Developers, Business Analysts, and Product Owners to improve product quality

• Develop and maintain automated test scripts

• Support release validation and production verification activities

Application Support & Issue Investigation

• Act as third-level support for production and UAT issues: triage, reproduce, and investigate incidents reported by underwriting, operations, agents, or business users.
• Trace issues across the stack — web UI behaviour, API request/response logs, application server logs, batch job logs, and Oracle data — to isolate root cause vs. symptom.
• Escalate defects to engineering with reproduction steps, environment details, and impact assessment; verify fixes before closure.

Qualifications:

• Bachelor’s or Master's degree in computer science, software engineering, Information Technology, or a related field.
• 3+ years of experience in software QA, application support, or a hybrid of both, in insurance, banking, or another regulated domain. Insurance core system experience (policy admin, quotation, or claims) is strongly preferred.
• Fluent, hands-on Oracle SQL: multi-table JOINs, aggregation, subqueries, date logic, and reading unfamiliar schemas to investigate issues independently.
• Proven experience investigating production issues using logs and data — not only executing test scripts.
• Working understanding of REST APIs: request/response structure, HTTP status codes, JSON payloads, and how to test them with Postman or similar tools.
• Clear written communication in Thai and English — investigation notes and defect reports will be read by engineering, business, and audit.
• Experience working in Agile/Scrum environments

Preferred Qualifications:

• Test automation experience — e.g. Playwright, Cypress, or Selenium for web UI; REST Assured or Postman collections + Newman for APIs. Willingness to grow into automation is valued even without deep experience.

• Familiarity with Angular or Vue.js applications from a testing standpoint (browser DevTools, network tab, console/error inspection, SPA state behaviour)

• Exposure to Java Spring Boot / Java EE server environments (reading application server logs, stack traces, log correlation)

• Experience with log/observability tooling (Kibana/ELK, Grafana, Splunk, or similar).

• Knowledge of Motor or Property insurance products: cover types, sum insured, endorsements, no-claim bonus, renewal cycles

Location: In Center of Bangkok (Pleonchit Tower, Chitlom BTS station)
