About this role.
Mantle is hiring a Blockchain Engineer to research and build blockchain protocols, modules, algorithms, and related infrastructure for institutional real-world-asset adoption. The role covers technical design documentation, testing strategies, proof-of-concept development, and knowledge sharing within the engineering team and broader community. Candidates need 1–5 years of relevant experience plus strong foundations in algorithms, distributed systems, cryptography, and blockchain platforms. Core technical requirements include Go, Rust, Solidity, and smart-contract development, while prior contributions to Ethereum, Solana, Optimism, Cosmos, OP Stack, or ZK-rollup ecosystems are advantageous. The remote position is limited to APAC and requires bilingual English and Chinese communication skills.

Sample interview questions
I would explain the problem, chain environment, trust assumptions, and protocol architecture before detailing choices around state management, consensus dependencies, contract interfaces, upgradeability, and security controls. I would also quantify outcomes such as lower gas usage, improved throughput, or reduced failure rates.
I would first define measurable hypotheses and threat assumptions, then build a minimal prototype with deterministic tests, integration tests, and adversarial cases. I would benchmark performance, assess security and operational risks, document trade-offs, and present a recommendation based on evidence rather than prototype success alone.
I start with authorization and access-control boundaries, reentrancy, unsafe external calls, arithmetic and accounting correctness, oracle assumptions, signature handling, upgradeability risks, and denial-of-service vectors. I combine manual review with unit tests, fuzzing, invariant testing, static analysis, and independent audit preparation.
A strong answer should describe concrete services or protocol components, such as node modules, indexers, transaction-processing services, networking layers, or cryptographic integrations. It should also cover concurrency design, error handling, testing, profiling, and the trade-offs that led to selecting Go or Rust.
I would create a concise bilingual design summary covering the problem, proposed solution, alternatives, security assumptions, expected impact, and open questions. For engineers, I would include implementation details and test plans; for community stakeholders, I would focus on benefits, risks, timelines, and transparent documentation.
Who we are
