Our platform replaces slow, manual processes with secure, automated workflows - delivering the first API-driven, real-time infrastructure for public companies.\nBacked by Index Ventures, Spark Capital, and Infinity Ventures, our team includes veterans from NYSE, Equiniti, Computershare, and AngelList. Engineering is headquartered in Mangaluru.\nAbout the Role\nYou'll play a crucial role in shaping our blockchain initiatives as a Smart Contract Developer. This is a growth hire: you'll set up a proof-of-concept (POC) to emulate transfer-agency workflows, primarily on Ethereum, with the flexibility to adapt to Solana or Canton based on your strengths. You'll join a collaborative team focused on blockchain and smart contracts, working closely with the tech lead, project manager, and product manager to gather requirements and plan milestones - co-creating the plan rather than waiting for tickets.\nKey Responsibilities\nDevelop and implement a POC for transfer-agency workflows on Ethereum, with the flexibility to adapt to Solana or Canton based on your expertise\n\nCollaborate closely with the tech lead, project manager, and product manager to gather requirements and plan milestones during onboarding\n\nDeliver key documentation by day 30, including requirements gathering and milestone planning, to ensure alignment and clarity\n\nProvide essential security deliverables by day 45, such as a threat model and testing plan, adhering to industry-standard security practices\n\nComplete the initial POC by day 60 and deploy contracts on both testnet and mainnet by day 90, ensuring all security standards are met\n\nRole Requirements\nMinimum 5 years of professional software/blockchain development experience\n\nWilling to relocate to Mangaluru, India (this is an in-office role)\n\nProficiency in Solidity and experience with Ethereum-based smart contract development\n\nExperience building decentralized applications and DeFi apps, demonstrating a strong understanding of blockchain technology\n\nAbility to gather requirements, plan milestones, and avoid project drift effectively\n\nOpenness to learning new technologies and adapting to evolving project needs\n\nTreats smart-contract security as a first-class concern, not a post-hoc checklist - has read post-mortems of on-chain exploits and internalized them\n\nWrites tests alongside the contract, and pushes back when a deadline threatens test coverage\n\nScopes aggressively on a greenfield POC - would rather ship a smaller, audited contract than a bigger one that isn't\n\nNice to Haves\nFamiliarity with Solana and/or Canton\n\nExperience with security tooling and practices, including threat modeling, audits, and systematic testing\n\nPrevious experience working in a collaborative team environment focused on blockchain and smart contracts\n\nBenefits\nCompetitive compensation based on experience\n\nOpportunities for professional development and growth\n\nA supportive team environment that encourages innovation and learning","description_format":"text","description_chars":3142,"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":["Equity","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":["Blockchain & Crypto","Financial Services","Cryptocurrencies","Custody & Fund Administration"],"lifecycle":[{"event":"open","at":"2026-10-24T15:01:58Z"}],"visa":[],"liveness":{"score":53,"band":"ok","label":"Likely open","p_open":1,"p_active":0.711,"p_room":0.75,"age_days":35,"expected_fill_days":36,"reasons":["conf:2","win:late"],"computed_at":"2026-10-27T05:46:45Z"},"pay":null,"html_url":"https://alion.io/job/vinyl-equity-blockchain-developer","json_url":"https://alion.io/job/vinyl-equity-blockchain-developer.json","meta":{"generated_at":"2026-10-28T03:57:00Z","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":5226,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":4394427},"rest":"https://alion.io/mcp/rest/get_company?id=4394427"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvinyl-equity-blockchain-developer"},{"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%2Fvinyl-equity-blockchain-developer"},{"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%2Fvinyl-equity-blockchain-developer"},{"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/vinyl-equity-blockchain-developer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvinyl-equity-blockchain-developer"}]}
