Blockchain Developer (DeFi and Cryptography)

Duration: 12 Months Contract

NC (Remote)

Job Description

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.

Mandatory Skills:

- 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.
