Blockchain Developer at Vinyl Equity in Mangaluru Office

Job description

• Application
• You'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.

Responsibilities

• Develop and implement a POC for transfer-agency workflows on Ethereum, with the flexibility to adapt to Solana or Canton based on your expertise
• Collaborate closely with the tech lead, project manager, and product manager to gather requirements and plan milestones during onboarding
• Deliver key documentation by day 30, including requirements gathering and milestone planning, to ensure alignment and clarity
• Provide essential security deliverables by day 45, such as a threat model and testing plan, adhering to industry-standard security practices
• Complete the initial POC by day 60 and deploy contracts on both testnet and mainnet by day 90, ensuring all security standards are met

Requirements

• Minimum 5 years of professional software/blockchain development experience
• Willing to relocate to Mangaluru, India (this is an in-office role)
• Proficiency in Solidity and experience with Ethereum-based smart contract development
• Experience building decentralized applications and DeFi apps, demonstrating a strong understanding of blockchain technology
• Ability to gather requirements, plan milestones, and avoid project drift effectively
• Openness to learning new technologies and adapting to evolving project needs
• Treats smart-contract security as a first-class concern, not a post-hoc checklist — has read post-mortems of on-chain exploits and internalized them
• Writes tests alongside the contract, and pushes back when a deadline threatens test coverage
• Scopes aggressively on a greenfield POC — would rather ship a smaller, audited contract than a bigger one that isn't
• Familiarity with Solana and/or Canton
• Experience with security tooling and practices, including threat modeling, audits, and systematic testing
• Previous experience working in a collaborative team environment focused on blockchain and smart contracts
