exposure to key management (MPC/HSM/multisig) a plus.\n\n- Working knowledge of DeFi primitives - AMMs, lending, staking, stablecoins, oracles - and their integration considerations.\n\n- Experience with cloud platforms (AWS or Azure), containers/Kubernetes, and CI/CD pipelines.\n\n- Security-conscious engineering habits : secure coding, thorough testing, and audit-ready contract development.\n\n- Strong ownership and delivery track record as a senior individual contributor within a squad.\n\n- Good communication skills; comfortable collaborating across engineering, product, and control functions.\n\nPreferred Qualifications : \n\n- Experience in a crypto exchange, Web3 protocol team, or blockchain-focused startup environment.\n\n- Contributions to open-source Web3 projects, hackathons, or personal on-chain projects.\n\n- Prior experience in fintech or regulated financial services.\n\n- Familiarity with account abstraction (ERC-4337), L2s/rollups, or cross-chain messaging.\n\nWhat We Offer : \n\n- The opportunity to build a regulated bank's digital asset platform from the ground up, with real production scale.\n\n- A high-ownership, fast-moving environment with direct exposure to senior leadership.\n\n- Competitive compensation and benefits aligned to the Gurgaon market.\n\nWio Bank is an equal opportunity employer.
