Job description

Role: Blockchain Developer (DeFi and Cryptography)
Location:  NC (Remote)
Duration: 12+ Months
Job Description
Blockchain Developer with DeFi and Cryptography experience: Proven track record of shipping production-grade decentralized applications.
- Multilingual Programming: Professional proficiency in Solidity and Rust, complemented by strong JavaScript/TypeScript or Python for tooling and testing.
- Core Architecture: Deep understanding of blockchain internals, including consensus mechanisms (PoS, PoW), state machines, and gas optimization techniques.
- DeFi Domain Expertise: Comprehensive experience with DEXs, liquidity provisioning, staking, derivatives, payments, lending, and complex tokenomics/token systems.
- Cryptography Fundamentals: Solid grasp of symmetric/asymmetric encryption, elliptic curve cryptography (ECC), and secure key management.
- Debugging & Testing: Expert ability to test, simulate, and fix complex bugs in distributed environments using frameworks like Hardhat, Foundry, or Anchor.
Note
About the Role We are seeking a highly skilled Blockchain Developer to join our core engineering team. In this role, you will be responsible for designing, developing, and deploying secure, high-performance decentralized finance (DeFi) protocols. You will bridge the gap between complex financial logic and low-level blockchain implementation, ensuring that our systems are not only innovative but also mathematically sound and resilient to attacks.
As a specialist in DeFi and Cryptography, you will take ownership of the full development lifecycle—from whitepaper logic and architectural design to mainnet deployment and post-launch optimization.
Key Responsibilities:
- Smart Contract Engineering: Design and implement robust smart contracts for DeFi primitives such as automated market makers (AMMs), lending pools, and cross-chain bridges.
- Protocol Security: Apply advanced cryptographic principles (e.g., digital signatures, hashing, zero-knowledge proofs) to ensure data integrity and user privacy.
- System Architecture: Design scalable back-end architectures that interface seamlessly with Ethereum, Layer 2 solutions, or Rust-based chains.
- DeFi Innovation: Research and implement cutting-edge DeFi mechanisms including flash loans, yield farming strategies, and algorithmic stablecoin logic.
- Audit & Quality Assurance: Conduct rigorous unit testing, integration testing, and formal verification to eliminate vulnerabilities before deployment.
- Collaboration: Work closely with front-end engineers to integrate Web3 providers and with UI/UX designers to create seamless decentralized experiences.
 
Preferred Qualifications:
- Experience with Layer 2 scaling solutions (Optimism, Arbitrum, ZK-Rollups).
- Familiarity with formal verification tools and smart contract auditing processes.
- Contributions to open-source Web3 projects or active participation in the DeFi research community. - Understanding of financial modeling and quantitative analysis.
