Java Backend QA Engineer (White-box Focus)
About the Role
We are looking for a passionate and curious Java Backend QA Engineer to join our team. You'll work closely with developers to ensure the quality of complex financial and Web3 products through deep technical testing — not just black-box validation, but real code-level understanding.
This is a great opportunity for a young talent who wants to grow fast in a high-impact, high-velocity fintech environment.
What You'll Do
-
Design and execute white-box and grey-box test strategies for Java-based backend services, including unit, integration, and API testing
-
Read and analyze Java source code to identify edge cases, logic flaws, and potential risk points
-
Build and maintain automated test frameworks and test tooling for financial backend systems
-
Collaborate with developers on code reviews, test coverage analysis, and CI/CD pipeline quality gates
-
Test and validate blockchain transactions, web3 wallet operations, and on-chain/off-chain data consistency
-
Investigate production issues, trace root causes through logs, DB records, and service call chains
-
Leverage AI tools (e.g., LLM-assisted test generation, log analysis, code review) to amplify testing efficiency
What We're Looking For
Required
-
1+ years of experience in software testing or backend development
-
Solid understanding of Java — able to read, write, and debug Java code confidently
-
Hands-on experience with backend testing: REST APIs, message queues (Kafka), databases (MySQL/Redis)
-
Familiarity with microservice architectures and distributed systems concepts
-
Strong analytical mindset with attention to detail and a passion for breaking things (in a good way)
Nice to Have
-
Experience in fintech, crypto, or blockchain domain testing
-
Knowledge of web3 wallets, on-chain data, or DeFi protocols
-
Familiarity with Spring Boot, Dubbo, or similar Java frameworks
-
Experience using AI-assisted tools in daily engineering work
-
Exposure to white-box testing techniques: code coverage, mutation testing, static analysis
How do I get a job at DeFi?
Getting a job in the DeFi (decentralized finance) industry can be a competitive process, but there are a few steps you can take to increase your chances of finding a job in this field:
- Build up your skills and knowledge: To work in DeFi, you'll likely need to have a strong understanding of blockchain technology, as well as other related technologies such as smart contracts and cryptocurrency. Consider taking online courses or earning a degree in a relevant field to build up your skills and knowledge.
- Network with industry professionals: Attend meetups and conferences related to DeFi and make connections with professionals in the industry. Networking can be a valuable way to learn about job openings and get your foot in the door at a DeFi company.
- Create a strong online presence: Many DeFi companies will look at your online presence (such as your LinkedIn profile and personal website) when considering you for a job. Make sure to showcase your skills and accomplishments online and keep your profile up to date.
- Apply for relevant job openings: Keep an eye out for job openings at DeFi companies and apply for positions that align with your skills and experience. Apply for DeFi Jobs without Experience. Tailor your resume and cover letter to the specific job you're applying for and highlight any relevant experience or skills you have.
- Consider internships or volunteer work: DeFi Internships or volunteer work can be a great way to get your foot in the door and gain valuable experience in the DeFi industry. Many companies also offer internships to students, so consider applying for an internship if you're still in school.
- Be persistent: keep trying if you don't get a job right away. It can take time to find the right opportunity, but with the right skills and determination, you can land a job in the DeFi industry.
