The mission of Trust Machines is to grow the Bitcoin economy. We’ve recently raised $150M to realize this vision, build Bitcoin apps, and the open-source technologies required to unleash the true potential of Bitcoin for DeFi and Decentralized Applications.

Trust Machines is building a DeFi Lending app, and we’re looking for a Smart Contract Engineer to join our remote-first team as one of the first dedicated smart contract engineers. The Lending app is building the bleeding edge of Bitcoin, using novel smart contracting functionality on Bitcoin to deliver a 10x improvement on existing DeFi lending. This role will be critical in building the protocol from the ground up, designing and developing the MVP, and working with the team to develop a robust and long-term product. The ideal candidate has start-up experience and is passionate about Web3 and DeFi.

Here’s what you’ll do:

  • Collaborate with our Lending and core engineering teams to architect a secure, decentralized, and highly-functional web3 lending app
  • Design, develop, and deploy smart contracts and decentralized applications on various blockchain platforms, writing clean, efficient, and maintainable code
  • Propose, execute, and iterate on research sprints to develop novel capabilities and technologies using Discreet Log Contracts on Bitcoin (no prior experience with Bitcoin script or DLCs required)
  • Collaborate cross-functionally with various TM teams including core engineering, product design, UX, and business development

What we're looking for:

  • A passion for Bitcoin, DeFi, and crypto
  • Hands-on experience with smart contract blockchains platforms like Ethereum (EVM), Cosmos, Solana, Stacks, or WebAssembly virtual machines
  • Fluency in Solidity or another smart contract language and a Github profile that demonstrates proficiency
  • Proven experience as a smart contract engineer or similar, with a strong understanding of blockchain concepts, consensus algorithms, and cryptographic principles
  • Familiarity with smart contract development tools and frameworks (e.g. Foundry, Hardhat, Remix, Web3.js)
  • 4+ years of work experience in software development, ideally including work in a DeFi protocol
  • Strong problem-solving and analytical skills, with a focus on discovering solutions instead of identifying roadblocks
  • Self-motivated and driven contributor, who can independently own feature development and collaborate with a team on best practices.

We’d also like to see:

  • Experience in the end-to-end full-stack development and/or launch of a Web3 DeFi protocol
  • Experience at a startup as an early engineer, even better if you’ve tried to launch your own project.
  • Strong communication skills
  • Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field

What we’ll offer:

  • Remote-first work environment
  • Awesome coworkers and a fun, collaborative environment
  • Contract details
    • Start: Immediate
    • Duration: 2 months, with possibility to extend or transition to full-time
    • Expected hours / week: 40
    • Hourly rate: $75-$150+
  • Equity in Trust Machines
  • Participation in future protocol incentives
