Blockchain Developer

ABOUT VINYL EQUITY
We're building the next generation of capital-markets infrastructure, starting with a modern, digital-native transfer agent designed for today's public companies. Our platform replaces slow, manual processes with secure, automated workflows — delivering the first API-driven, real-time infrastructure for public companies.
Backed by Index Ventures, Spark Capital, and Infinity Ventures, our team includes veterans from NYSE, Equiniti, Computershare, and AngelList. Engineering is headquartered in Mangaluru.
ABOUT THE ROLE
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.
KEY 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
ROLE 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
NICE TO HAVES
- 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
BENEFITS
- Competitive compensation based on experience
- Opportunities for professional development and growth
- A supportive team environment that encourages innovation and learning
