Role overview
Backend Engineer (Remote, Global)
Requirements and responsibilities
Readable role content extracted into sections for faster review.
Qualifications:
- You have 8+ years of industry experience in backend engineering, focusing on speed and low-level optimization. (example domains: game engines, databases, blockchain node implementations, HFT, virtualization, hardware-accelerated computation, compiler optimization, physics simulation, rendering pipelines, etc.)
- You are proficient in a low-level programming language such as C/C++, Rust, Go, Java.
- You thrive in a globally-distributed, asynchronous-by-default work environment that values deep work, quality engineering, and written communication. (e.g., design docs, documentation, runbooks, etc.)
We appreciate, but don’t require:
- Experience with the Ethereum development stack (e.g., Solidity, EVM, etc.)
- Experience building HFT algorithms and infrastructure
- Production experience with Machine Learning / Reinforcement Learning
Expectations:
- You will write performance-sensitive code to run “whole-world” simulations of DeFi, along with supporting distributed systems, data and ML pipelines.
- Our tech stack consists of Rust, Golang, Python, PyTorch, Nomad, Consul, etc. We expect you to become proficient in Rust and self-sufficient with the rest.
- We don’t require pre-existing knowledge of blockchain internals, but you will have to dive deep into various L1/L2 blockchain networks and determine how to integrate them into our simulation infrastructure.
What we offer:
- Competitive salary and equity
- Performance-based cash bonuses from our trading business (Unlike a typical technology startup, our business model allows us to provide both equity and liquidity.)
- Full medical, dental, and vision insurance
- Paid parental leave
- Flexible work hours - we are fully remote and globally distributed
- Stipend for home-office equipment and ergonomics
