We are a venture-backed startup using low-latency optimization, concurrency, and distributed systems engineering to build the Monad blockchain, a high-performance smart contract platform with throughput that is orders of magnitude higher than any existing blockchain. We are a small team with deep expertise in low-latency software and distributed systems; we’re in search of a few more exceptional engineers who want to work on challenging problems with massive impact.

Our work entails building an optimal stack-based virtual machine that supports multithreaded computation, as well as developing an efficient Byzantine Fault Tolerant (BFT) algorithm for maintaining consistent state across a distributed network.  The result is a blockchain offering the best of both worlds—performance and portability—for smart contract developers, paving the way for much cheaper on-chain computation and much broader adoption of decentralized apps.

We are looking for exceptional software engineers who enjoy solving challenging performance engineering and low-level optimizations problems. You will be part of a small, exceptional team, working on high-impact problems in a fast-paced environment. We think that you'll find the work very challenging and rewarding. Experience with crypto is not expected.

Who you are

  • Resourceful and self-motivated
  • Team oriented, collaborative, and a good communicator
  • Adaptive; able to make meaningful contributions in a fast-paced environment
  • Opinionated about software architecture
  • Motivated to push the limits of system performance through repeated optimization
  • Interested in building high-value fault-tolerant distributed systems


  • BS or higher degree in CS or related field
  • Expert in C++ programming
  • Strong understanding of concurrency, memory management, and low-level optimization
  • Excellent instincts for software architecture
  • Bonus: experience with distributed systems, applied cryptography, compilers, or networking
  • Bonus: proficiency in go

What you’ll be doing

  • Designing and building a high-performance multithreaded stack-based VM, as well as ancillary functionality (disk I/O, computation metering, network)
  • Designing and building improvements to a distributed system kept in sync by a Byzantine Fault Tolerant (BFT) consensus mechanism
  • Identifying bottlenecks through profiling, and evaluating design choices for accelerating computation flow
  • Contributing to developer tooling
  • Tech stack: C++, go, clang, LLVM, gdb, perf, unix, git

Why work with us

Working at Monad Labs means doing challenging work on a high-impact problem with exceptional teammates.

Here are some of the people you’ll work with:

  • James, performance engineering expert and system architect; previously designed and built ultra-low-latency systems for a top high-frequency trading team at Jump Trading;
  • Ariq, expert at low-level firmware and software programming; previously a senior engineer at Arista Networks, where he served as lead maintainer on multiple linux kernel networking drivers for Arista EOS devices;
  • Aashish, expert systems designer and hacker, previously the first engineer at Pattern Research, a leading crypto HFT firm, where he designed and built the entire trading stack from scratch; graduated from MIT at age 19

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 deeply impactful, enabling much cheaper and more efficient decentralized computation and ultimately paving the way for new dapps that improve many people’s lives.
