About The Opportunity
We are looking for an experienced blockchain developer to join our team building the next generation of high-performance on-chain trading infrastructure. You will help design and implement a unified trading engine — supporting Perpetuals, Spot, and Prediction Markets under a single margin account — and contribute to ExchangeOS, an infrastructure layer that lets KYC'd institutions and Web3 entities stake to create and operate their own trading venues (DEXs) on top of our chain.
What You’ll Be Doing
- Design and build a unified account and matching system that supports Perpetuals, Spot, and Prediction Markets — including on-chain order matching, cross-margin validation, settlement, and liquidation/risk engines.
- Build and optimize the core components of ExchangeOS: the staking/venue-creation framework that allows KYC-verified institutions and Web3 protocols to launch and operate their own dex on shared infrastructure.
- Drive performance engineering across the stack — parallel transaction execution, low-latency order pipelines, and throughput/latency optimization at the engine and chain level.
- Track cutting-edge blockchain and trading-system technology and apply best practices to our infrastructure.
- Partner with product and business teams to translate venue/exchange requirements into technical designs, and provide ongoing technical support.
What We Look For In You
- Strong proficiency in Rust, with hands-on experience in high-performance, low-latency systems.
- Deep understanding of exchange/matching engine mechanics.
- Solid grounding in blockchain fundamentals.
- Strong systems-performance mindset.
- Excellent teamwork, communication, and logical reasoning skills.
Perks & Benefits
- Competitive total compensation package.
- L&D programs and Education subsidy for employees' growth and development.
- Various team building programs and company events.
- Wellness and meal allowances.
- Comprehensive healthcare schemes for employees and dependants.
