Role Overview

We are looking for a Senior Solidity Engineer to join our core team. Your work will include the design, implementation, and deployment of critical infrastructure powering the Monad blockchain.

You will contribute to development of major projects with a smart contract component, such as bridges, order books, staking, and NFT minting services.

You’ll contribute to design, development, testing, and deployment of these new features. You’ll make critical decisions on security and maintainability. Your work will power components with billions of dollars of TVL; as such, you’ll need to maintain exceptional focus in defining invariants and defending against attacks.

You’ll also contribute to design and development of new VM features that enable developers to build more powerful dapps. The smart contracts you develop will serve as initial use cases for new features that we are pioneering in the Monad VM, which supports and extends the EVM.


  • You’ll contribute to design and development of major projects with a smart contract component such as bridges, order books, staking, and NFT minting services. This will draw on your knowledge of existing tools as well as leveraging new primitives in Monad’s VM
  • You’ll develop rigorous unit and integration tests, and thoroughly consider potential attack vectors
  • You’ll contribute to architectural decisions that maximize security and minimize trust requirements
  • You’ll collaborate with the rest of the team to develop features of the Monad VM
  • You’ll hire other smart contract engineers
  • You’ll mentor junior engineers and interns
  • You’ll think strategically about initiatives or features that will aid in early adoption of the Monad blockchain


Required prior experience:

  • 3+ years of smart contract development including production deployments of original protocols
  • Extensive knowledge of Solidity and the EVM
  • Extensive knowledge of smart contract security and common pitfalls (e.g. you understand the cause of all historical reentrancy attacks and other vulnerabilities)
  • Extensive experience with proper deployment and security practices
  • Experience writing extensive unit and integration tests

Required personal attributes:

  • Extreme attention to detail
  • Auditor/hacker mindset
  • Low ego
  • Independence
  • Extremely strong work ethic
  • Ambition/desire to make a massive impact
  • Enthusiasm for Monad’s mission of helping decentralization scale

Bonus points:

  • Experience with auditing smart contracts
  • Earned bug bounties
  • Experience building and managing a protocol with significant TVL is a plus
  • Experience writing high-performance C++

Culture & Perks:

Why work with us:

  • You’ll work on extremely challenging problems with massive potential impact
  • You’ll work with and learn from a small, exceptional team
  • You’ll receive a competitive salary, along with equity
  • You’ll shape the culture as an early employee and make impactful contributions from day one
  • You’ll be part of a flat, results-driven organization
  • Your work will be extremely impactful in enabling onramps and usage of the Monad blockchain, facilitating adoption by many users.
  • Your work will be deeply impactful, enabling much cheaper and more efficient decentralized computation and ultimately paving the way for new dapps that improve many people’s lives

Salary and benefits:

Minimum full-time salary of $200,000-$250,000. (**This is not a guarantee of compensation or salary; a final offer amount may vary based on factors including but not limited to experience and geographic location.)

Monad Labs’ benefits include unlimited and encouraged paid time off; 100% medical, dental, and vision coverage; home office equipment stipend; monthly wellness/fitness stipend; and 11 company-observed holidays.

The majority of our team is in NYC and works together a few days a week. We are open to remote candidates in the US and Canada, with a strong preference for candidates based in (or able to relocate to) NYC.

About Us

Monad Labs is creating the foundation for a new world of powerful decentralized applications. We’ve developed the first parallel EVM executor, and have paired it with significant innovations on consensus, pipelining, and storage to build the Monad blockchain, an ultra-performant EVM-equivalent blockchain supporting 10,000 TPS while remaining highly decentralized.

Founded by Jump Trading alums, our team solves challenging problems in distributed systems engineering and low-latency optimization, authoring software innovations that enable a new, high-performance decentralized system that is backward-compatible with existing EVM apps and Ethereum infrastructure. We are backed by notable leaders in the crypto space, including Dragonfly, Cobie, and Hasu.

Our mission is to enable a new universe of decentralized apps—use cases and user flows that are currently impossible—by drastically reducing EVM computation costs. Ultimately, our work will unleash the power of decentralization to make the world more efficient and fair.
