Senior Software Engineer, Compiler

Compiler Engineer Opportunity

Category Labs (formerly known as Monad Labs) is a team of systems engineers and researchers on a mission to design and build at the frontier of decentralized technology. We strive to design and build step-function improvements over existing blockchain solutions. After raising $225M in series A funding, led by Paradigm, we are growing our team.

The Role

We are looking for an exceptional compiler engineer to work on challenging greenfield projects that accelerate bytecode execution. For example, you will work on a bytecode execution graph builder which will enable speculative pre-execution of potential control flow paths. Your work will require intensive research and engineering and will help accelerate a platform securing billions of dollars in value. Experience with crypto is not expected.

What You Will Do

• Work on greenfield performance-oriented projects in a fast-moving startup environment
• Research ideas for accelerating EVM bytecode execution
• Design and implement performant production systems

Why Work with Us

• Challenging problems. You'll work on extremely challenging problems with massive impact.

• Huge opportunity. The Ethereum Virtual Machine (EVM) standard is ubiquitous, but existing EVM-compatible chains are very slow. Monad's core innovations offer developers the best of both worlds (portability and performance) and are a game-changer for mass user adoption in crypto.

• The right team. You'll be part of a small, exceptional team (engineers and researchers make up 90% of the team).

• Culture. We're a lean team working together to achieve very ambitious goals. We are united in our culture of collaboration, low ego, and high-quality output. As an early member of our team, you'll help to shape our culture.

• Compensation. You'll receive a competitive salary and equity package.

• Resources and growth. We're well-capitalized, with backing from leading venture funds like Paradigm, Electric Capital, Greenoaks, Dragonfly, and Coinbase Ventures. We keep a lean team, and this is a rare opportunity to join. You'll learn a lot and grow as our company scales.

Who You Are

• Proven track record in compiler design and system architecture

• Strong background in software engineering principles

• Experience with industry-standard compiler technologies

• Good understanding of testing and benchmarking

• Industry and/or academic experience working on compilers for parallel architectures

• Strong C++ programming skills

• Knowledge of type theory is a plus

Salary and Benefits

The target annual salary range for this US-based role is $180,000 – $250,000. This range represents our good-faith estimate at the time of posting and is not a guarantee of compensation. The final offer may vary based on factors including experience, domain expertise, and the candidate's specific geographic location.
