About Truffle 

We make open source tools for building blockchain applications. Our tools let users simulate blockchain virtual machines, debug smart contracts step-by-step, manage suites of automated tests, deploy applications to live networks, interface with smart contracts at a high level of abstraction, and much more. We believe that software development tools should offer sensible defaults and never lose sight of human intent amidst low-level details.

About the Role

Are you interested in creating the future of the decentralized application (dapp) developer experience? Building on blockchains requires a new mindset, end-user considerations, and grappling with new technological challenges. These facets need to be deeply considered when building the tools that designers, engineers, security auditors, and solution architects use on a daily basis. While the journey has begun, there’s still so much to solve!

Join a team that’s laser-focused on making the dapp developer experience as effortless as it both can and needs to be in order to realize the true potential of blockchains and web3.

What you’ll bring to the role: 

  • A passion for decentralized computing and its disruptive potential
  • An appreciation of the core constructs of decentralized systems such as consensus algorithms, network & data exchange protocols, cryptography, trust models, etc
  • Demonstrable experience with a modern programming language and its associated tooling, such as Node.js, Python, Go, or Rust
  • Hands-on experience with a variety of stages of the application development lifecycle (wireframing, prototyping, architecting, development, support, scaling, etc)
  • Experience with a smart contract development language (Solidity, Vyper, etc.)

Skills you’ll learn, or improve upon:

  • ES6 / Node.js and working within its associated ecosystem
  • Real world Decentralized Application (dapp) development
  • Open source software contribution and/or project maintenance
  • Technical writing including documentation, tutorials, etc
  • Involvement with a technically-focused developer community

Unsure whether you qualify but excited about the role? Apply anyway! We’d love to hear from you.

What’s it like to work at Truffle within Consensys?

We believe in cultivating autonomy, mastery, and purpose, both for ourselves and for our community. We recognize that developing great software requires passion for the positive impact of the work and passion to support each other as a team. We recognize each other by our strengths, not our weaknesses, and we maintain space for everyone to say “I don’t know.” We work remotely except for when we meet up with each other (pandemic aside) at conferences or as a group at team retreats. We’re a dedicated team with a playful sense of humor, constantly seeking new ideas.


Here are some of the perks of being part of the Truffle team at a unique organization like ConsenSys:

  • One of the most recognized tech companies in the blockchain ecosystem globally. A work experience at ConsenSys is a tremendous reference for your future career. ConsenSys alumni have moved on to become tech entrepreneurs, CEOs, and team leads at tech companies.
  • The forefront of a revolution. We fundamentally believe blockchain is a next generation of technology that  can lay the foundation for a more just and equitable society. You can be a part of building the digital economy of tomorrow and radically transforming our society for the better.
  • A dynamic startup environment with deep roots. We are one of the earliest blockchain companies and a leader in the space.  You’ll join a network of entrepreneurs and technologists that reaches the edge of our ecosystem.   
  • Deep technical challenges. Blockchain  technology is just over 10 years old. Ethereum itself is still a toddler. There is much to be done before these platforms can scale to the order of millions or billions of users. We are building the tools, infrastructure and applications l that are pushing the technology forward.
  • Continuous learning and improvements. You’ll be constantly exposed to new concepts, ideas and frameworks from your peers and as you work on different projects — challenging you to stay at the top of your game.
