About Magent

Magent, a Reap Company, is redefining how crypto natives and hybrid users spend and earn by bridging decentralized finance (DeFi) with real world transactions. Unlike traditional crypto cards, Magent doesnt just enable spending, we allow for idle crypto assets to work for users through automated DeFi earnings. By partnering with wallets and DeFi protocols, Magent creates a low risk, high utility financial experience, bringing true DeFi powered financial freedom to a global audience. This is a chance to join early and play a key role in shaping the future of Magent.

The Role

As a key member of the Magent team, youll be designing and maintaining smart contracts on Solana and working closely with backend systems (Node.js/TypeScript) as core parts to the role. Youll optimize for reliability, security, and scalability. Cross chain experience (e.g., token bridges, interoperability protocols) is a plus, as we aim to expand blockchain support beyond Solana.

This role is ideal for someone who is also commercially minded and understands how technical decisions can affect the user experience and business model.

What Youll Do

• Develop and maintain Solana programs in Rust that support existing product features and DeFi integrations in addition to future product builds.
• Build and optimize backend services (Node.js/TypeScript) to support on-chain integrations.
• Collaborate with the product team to translate business logic into secure, on chain functionality and new experiences.
• Participate in architecture decisions, especially for cross-chain expansion and scalability.
• Contribute to code reviews, audits, and performance optimization.

What Were Looking For

• Lateral thinker/problem solver who thrives in positions of autonomy and who is looking to take oversized ownership while getting their hands dirty in a start up environment.
• Strong proficiency in Rust and Solana program architecture.
• Strong Typescript and Node.js backend development experience.
• Understanding of blockchain engineering.
• Experience using and technical understanding of the Solana DeFi ecosystem.
• Ability to work in a lean, minimal-tooling environment.
• Bonus: cross-chain development experience, credit/finance systems or credit card industry knowledge.

Why Join Us

Youll be working directly with the co-founders on a high impact product from the ground up. Your work will directly power a crypto credit card product that merges DeFi and traditional payments. Were small, fast, and building something that the market hasnt seen; youll be a core part of making it happen.
