[Hiring] Software Development Engineer in Test @Sertis

Role Description

We are looking for a Software Development Engineer in Test to join our team, focused on validating a Java codebase migration. Unlike a traditional QA role, this position requires strong Java development skills. You will:

• Design and implement test strategies for the Java 8 to Java 21 migration, covering compatibility, regression, and behavioral validation.
• Write and maintain automated test code in Java for API, backend services, and integration layers.
• Build, extend, and own our existing Java-based automation framework running in Jenkins.
• Set up and maintain CI/CD pipelines using Pipeline-as-Code (Groovy/Jenkinsfile).
• Validate functional and non-functional behavior of migrated services, identifying edge cases and compatibility risks.
• Perform API, integration, and regression testing across the application stack.
• Collaborate with Java Developers to review code changes, assess migration risks, and define test coverage.
• Manage and triage defects with clear root cause analysis and technical documentation.
• Maintain test documentation, test cases, and validation reports.

Qualifications

• 2-4 years of Software Development in Test (SDET), test automation engineering, or backend development experience, with at least 1-2 years writing automation in Java.
• Strong Core Java (JSE) skills, multithreading, collections, memory management; must write clean, maintainable test code, not just execute scripts.
• Solid understanding of Java version differences, including module system changes, deprecated APIs, and runtime behavioral differences.
• Hands-on experience building or extending automation frameworks.
• Strong experience in API testing and backend validation using RestAssured, Postman, or similar tools.
• Hands-on Jenkins experience, writing and maintaining Jenkinsfiles, integrating test suites into deployment pipelines.
• Working SQL knowledge, writing and validating queries, understanding schema design, verifying data integrity in relational databases.
• Familiarity with test management and defect tracking tools (Jira, TestRail, or similar).
• Strong English communication skills (written and spoken) for collaboration with a US-based team.
• Ability to work fully remote under US time zones.

Requirements

• Experience in fintech or high-transaction systems (payments, ledgers, financial data pipelines).
• Familiarity with NoSQL databases and RDBMS interaction via application layers.
• Experience with performance/load testing tools (JMeter, K6, or similar).
• Understanding of logging, monitoring, and observability tools (ELK, Grafana, Datadog, or similar).
• Exposure to AI-assisted development tools applied in a testing or coding context.

Benefits

• Fully remote position (work from anywhere under the US time zones).
• Opportunity to learn modern Java practices on a real migration project with senior mentorship.
• Collaborative and supportive team environment.
