Blockchain Engineer (Solana)

We’re working with a fast growing fintech innovator that's scaling up its blockchain initiatives.
‍

They're hiring for Blockchain Engineers to drive brand-new projects at the intersection of decentralised finance and digital payments. This is a unique opportunity to become the founding blockchain specialist(s) in a product-driven, mission-led organisation.

The Opportunity

Multisig Wallet Infrastructure (B2B)

The client is investing in building secure, scalable on-chain infrastructure to replace traditional off-chain systems. With inspiration drawn from the success of Squads Protocol (which has surpassed $10B in assets under management), there's a strategic focus on launching robust multisig wallet solutions for business users.

Expect to work on infrastructure that prioritises transparency, programmable access controls, and real-time settlement — removing the inefficiencies and risks of intermediaries.

DeFi-Powered Consumer Payments (B2C)

Their second initiative is aimed at merging everyday consumer payments with decentralised finance. Unlike standard crypto cards, this product enables users not just to spend, but to earn automated DeFi yields on idle assets — blending usability with financial empowerment. You'll be joining at the ground level to shape the tech stack, architecture, and long-term roadmap.

The Role

We're looking for a Senior Blockchain Engineer or Blockchain Architect with deep experience building smart contracts in either Solana (Rust) or Ethereum/EVM-compatible chains (Solidity).

This role is hands-on and highly cross-functional — you’ll partner with product, business, and design teams to architect, build, and scale real-world blockchain applications. It's ideal for engineers who can combine technical excellence with strong product intuition.

Responsibilities

• Architect and implement production-ready smart contracts.
• Build scalable, secure blockchain systems for asset management and transaction processing.
• Develop backend services (Node.js/TypeScript) to complement on-chain logic.
• Collaborate across product and business teams to align technology with user needs.
• Own technical decisions, code reviews, and participate in security audits.
  ‍

What We’re Looking For

• 5+ years of software development experience.
• 2+ years building smart contracts in Rust (Solana) or Solidity (Ethereum/EVM).
• Strong backend development experience with Node.js and TypeScript.
• Product-driven mindset with strong ownership over outcomes.
• Excellent communication and collaboration skills.

Bonus Points For

• Experience with DeFi protocols or cross-chain integrations.
• Understanding of payments systems or financial infrastructure.
• Previous startup experience, especially in early-stage environments.

Why This Role Stands Out

• Real DeFi Applications: Build tools that bridge the gap between decentralised finance and real-world utility.
• Blockchain Innovation: Work directly with Solana and Ethereum, with opportunities to expand into other chains.
• Meaningful Scale: Your work will support real users and large transaction volumes globally.
• Well-Funded: The company is backed by leading global investors and is committed to long-term blockchain investment.
• Flexible Work Environment: Join a global team with flexible hybrid or remote work options.
