QA Engineer 区块链测试工程师
WFA Digital Insight
Windranger Labs is building Mantle, a bridge that lets traditional finance interact with real‑world assets on public blockchains. Their QA Engineer role sits at the core of that effort, requiring hands‑on testing of smart contracts, DApps and the browsers that host them. Unlike generic QA positions, this job expects you to shape the testing framework for a nascent ecosystem, review architecture decisions, and push automation from unit tests to chaos‑engineered stability runs. Candidates will need deep familiarity with Hardhat or Foundry, solid Python or Go skills, and a proven track record of delivering end‑to‑end test suites for public‑chain projects. If you thrive on solving obscure blockchain bugs and enjoy influencing product design from day one, the role offers a rare chance to leave a technical imprint on a fast‑moving Web3 infrastructure.
Job Description
Who we are
Mantle is the entry point for institutions and traditional finance to access real-world assets on-chain. Backed by the world’s largest community-owned treasury of over $4B, Mantle combines institutional-grade infrastructure with the scale and credibility to bring RWAs into Web3 with confidence.
Mantle positions itself as the gateway for institutions and TradFi to move into RWAs on-chain. With $4B+ in community-owned assets, Mantle combines credibility, liquidity and scale with institutional infrastructure to support large-scale adoption. The ecosystem is anchored by $MNT in the Bybit network, and built out through subsidiaries mETH, fBTC, MI4 and MantleX. This is complemented by Mantle Network’s partnerships with leading issuers and protocols such as Agora AUSD, Ethena USDe, Ondo USDY and EigenLayer.

Key Responsibilities
End-to-End Testing: Responsible for functional, performance, security, and automation testing of blockchain products, deeply participating in the entire project R&D lifecycle.
Requirement & Architecture Review: Participate in project requirement analysis, focusing on feasibility and testability; take part in major product requirement and architecture design reviews to ensure the rationality of product design and architecture.
Efficiency & Automation: Write automation test cases, develop testing tools, and build test platforms to enhance overall testing quality and efficiency.
Blockchain Testing Framework: Maintain a deep understanding of blockchain-related knowledge; research and overcome key technical challenges in blockchain testing to establish a comprehensive blockchain testing ecosystem.
DApp Testing: Conduct thorough testing for DApps, including functional, performance, and security assessments.
Browser Testing: Maintain a solid understanding of blockchain-supported web browsers and execute related testing tasks.
Requirements
Education: Bachelor’s degree or above in Computer Science, Software Engineering, or a related field.
Experience: 2+ years of experience in blockchain test development, with hands-on experience in DApp testing.
Tools: Familiar with smart contract testing frameworks such as Hardhat and Foundry.
Languages: Proficient in programming languages such as Python and Golang, with good coding practices.
Automation: Familiar with mainstream automation frameworks (e.g., unittest , go test ) with proven experience in successfully implementing automation testing projects.
Performance & Stability (Bonus): Experience in independently setting up performance and stability testing initiatives is a strong plus. Ability to design pressure tests for different business scenarios and build stability testing based on Chaos Engineering principles.
Domain Knowledge: Familiar with Ethereum or other public chain projects, with extensive experience in public chain testing.
How to Stand Out
- Showcase a portfolio of automated blockchain tests, preferably including Hardhat or Foundry scripts, on GitHub.
- Highlight any chaos‑engineering or performance‑testing projects you have built, describing the methodology and outcomes.
- Prepare to discuss specific smart‑contract bugs you discovered and how you resolved them during interviews.
- Brush up on the differences between Ethereum mainnet and testnets; interviewers often probe edge‑case handling.
- Emphasize your ability to work asynchronously across time zones; provide examples of remote collaboration successes.
- When negotiating, consider equity and remote‑work stipends as part of the total compensation.
- Watch for vague language around on‑call responsibilities; ask for clarity on expected support rotations before accepting.
