We provides IT services and consulting tailored for small healthcare businesses and private practices. Our mission is to help providers enhance efficiency, ensure data security, and adopt cost-effective technology solutions that support high-quality care.

In addition to healthcare IT support, we develop custom software solutions designed to meet the unique needs of small healthcare organizations. Our team builds secure, user-friendly, and HIPAA-compliant tools that simplify operations and improve patient outcomes.

Flourish Health is also exploring opportunities in the blockchain industry, aiming to leverage decentralized technologies to improve data integrity, transparency, and trust in healthcare and beyond.

At Flourish Health, we make technology simple, reliable, and accessible—so healthcare professionals can thrive in a digital world.

The Role

We're An Early-stage Team Building a Project— a Fully On-chain Decentralized Borrowing Protocol — And We're Currently Looking To Bring On Two Web3 Developers

  • Frontend Developer – to help update and improve our React.
  • Smart Contract Developer – to build and integrate contracts using Solidity, ethers.js, wagmi, etc.

We're aiming to hire both by next month. Since we're a small, fast-moving startup, there's no formal hiring process — just a focus on working with skilled, motivated builders who can move fast.

These are short-term roles, but we’re open to extending the collaboration if it’s a good fit. Experience with multi-chain (EVM) development is a big plus.

Ideal Profile

  • You have hands-on experience building in Web3, with strong skills in React or Solidity/EVM tools like ethers.js, wagmi, or hardhat.
  • You have at least 3 years experience, ideally within a Software Engineer role.
  • You thrive in early-stage startup environments — you’re self-motivated, fast-moving, and able to take ownership without heavy structure.
  • You possess strong analytical skills.
  • You’re passionate about blockchain, decentralized finance (DeFi), or the future of technology in healthcare.

What's on Offer?

  • Join a fast-moving startup building a fully on-chain decentralized borrowing protocol — shape the future of Web3 in healthcare and beyond.
