• Guardian of Uptime: Take primary responsibility for ensuring the stability and availability of our production applications and blockchain infrastructure. • Environment Management: Oversee pre-production and staging environments to ensure seamless delivery. • Incident & Problem Management: Lead the triage of application alerts, conduct deep-dive root cause analysis (RCA), and manage post-resolution follow-ups to ensure issues never resurface. • Disaster Recovery: Coordinate DR testing, audits, and continuous improvement of monitoring tools and processes. • Support Transformation: Apply hands-on AI experience to build tools and agents that automate repetitive support tasks, triage, and reporting. • Proactively keeping abreast with updates on supported blockchains and DApps and demonstrating a sharp ability to technically deconstruct new blockchains or DApps as required to evaluate their impact of supportability on our product.

Role 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. 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. 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.
