You will own features end-to-end, contribute to design decisions, and hold a high bar for code quality, testing, and reliability.\n\nKey Responsibilities :\n\n- Develop and maintain production-grade smart contracts and protocol integrations (EVM/Solidity), including testing, deployment, and upgrade workflows.\n\n- Build backend services and APIs (microservices, event-driven architecture) connecting on-chain activity with the bank's core platforms, ledgers, and compliance systems.\n\n- Implement wallet and transaction-orchestration features - signing flows, nonce and gas management, chain indexing, and reconciliation of on-chain data.\n\n- Integrate with DeFi protocols, oracles, and bridges safely, with robust failure handling and monitoring.\n\n- Write clean, well-tested code - unit, integration, and contract testing (Foundry/Hardhat) - and contribute to CI/CD pipelines and observability.\n\n- Participate in design reviews and technical discussions, contributing to architecture decisions within your squad.\n\n- Work closely with Security, Risk, and Compliance to ensure everything shipped meets the bar of a regulated bank.\n\n- Support production systems: participate in on-call rotations, debug incidents, and contribute to root-cause analysis and fixes.\n\n- Collaborate with product managers and designers to translate requirements into reliable, scalable solutions.\n\n- Keep current with the Web3 ecosystem - new standards, tooling, and best practices - and share learnings with the team.\n\nRequired Experience & Skills :\n\n- 5+ years of software engineering experience, with 1 - 2+ years building blockchain, Web3, or DeFi systems (production experience preferred).\n\n- Hands-on smart contract development experience (Solidity/EVM) and familiarity with modern tooling (Foundry, Hardhat).\n\n- Strong backend skills in at least one of: TypeScript/Node.js, Go, Rust, Java/Kotlin, or Python - with solid grounding in distributed systems fundamentals.\n\n- Understanding of wallet infrastructure, transaction signing, and chain indexing; 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.\nSkills\nSolidity, Blockchain, Node.js, Rust, AWS, Golang, Web3.js, Python, Emerging Technologies, Smart Contract, DeFi Protocols","description_format":"text","description_chars":3919,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","DeFi","Web3 & dApps"],"lifecycle":[{"event":"open","at":"2026-09-25T18:04:06Z"}],"visa":[],"liveness":{"score":22,"band":"cold","label":"Long shot","p_open":0.6,"p_active":0.674,"p_room":0.55,"age_days":33,"expected_fill_days":27,"reasons":["seen:33","velocity","win:tail"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/talentgen-advisory-llp-senior-software-development-engineer-blockchain-defi","json_url":"https://alion.io/job/talentgen-advisory-llp-senior-software-development-engineer-blockchain-defi.json","meta":{"generated_at":"2026-10-21T02:13:07Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":3352,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3800611},"rest":"https://alion.io/mcp/rest/get_company?id=3800611"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftalentgen-advisory-llp-senior-software-development-engineer-blockchain-defi"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Ftalentgen-advisory-llp-senior-software-development-engineer-blockchain-defi"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Ftalentgen-advisory-llp-senior-software-development-engineer-blockchain-defi"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/talentgen-advisory-llp-senior-software-development-engineer-blockchain-defi\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftalentgen-advisory-llp-senior-software-development-engineer-blockchain-defi"}]}
