We are seeking a skilled Senior Blockchain Developer to join our team at Crossmint, where we are revolutionizing payments in the NFT space. This is an exciting opportunity to be part of a mission-driven company that is accelerating the transition to a more secure and transparent digital world.

About Us

Crossmint is a leading provider of APIs and tools that make it 100x easier to create, custody, and commerce with digital assets (NFTs) and verifiable credentials (VCs). Our solutions abstract out all the complexities of interacting with blockchains, making it simple for companies to integrate NFTs, wallets, or credentials into their systems.

Job Description

We are looking for a highly experienced Senior Blockchain Developer who can develop smart contracts, protocols, and backend integrations around them. As a key member of our team, you will be responsible for writing high-quality smart contract code, integrating with our backend and frontend, and mentoring junior developers.

Responsibilities:

  • Write high-quality smart contract code: correct, gas optimized, maintainable.
  • Integrate with our backend and frontend systems.
  • Mentor junior developers and contribute to our team's growth.

Requirements:

  • Provable experience shipping high-quality smart contract code.
  • Excellent reading and writing comprehension skills in English.
  • Experience working on a team and references to back it.
  • Educational Background: Hold a Bachelor's degree in Computer Science or a related field, or equivalent knowledge and skills with industry experience.
  • Professional Experience:
    • 2+ years of experience working on smart contract development. Reusing an existing OpenZeppelin contract for an NFT drop doesn't count, we look for novel smart contract development experience.
    • 2+ years working on security-critical projects. We will ask you about how you ensure your code has the lowest chances of including bugs in production.
    • 2+ years designing protocols in one of more of the following fields: blockchain applications, decentralized finance, digital credentials and identity, authentication, authorization, or distributed systems.
  • Programming Expertise: Demonstrate expertise in multiple modern programming languages, including a focus on smart contract languages such as Solidity, Rust, or Move.

Benefits

  • Highly competitive location-based compensation ($205,000 - $220,000 per year).
  • Stock options program.
  • Unlimited, flexible PTO.
  • Flexible work schedule.
  • Company laptop and allowance for any necessary home equipment.
  • Daily stipend for commuting to the office.
  • Company-paid trips for annual off-sites and on-sites.
  • Health, dental, vision, life, short-term disability (STD), and long-term disability (LTD) insurances.
  • 401(k) Plan.

Our Principles

  • Results and delivery: we value shipping high-quality and impactful code.
  • Build for the long term: we value building systems that stand the passage of time: scalable, secure, and reliable solutions.
  • Extreme Ownership: we look for individuals with high agency, self-motivated, and driven who can own their projects end-to-end and help push the company forward.
  • Be a team player: we look for kind individuals who can work in a team effectively, and also upskill the team they work on. In this role, we specifically value mentorship ability.
