Original job description

About Decibel Decibel is a fully on-chain perpetuals and spot exchange built in collaboration with Aptos Labs and the Decibel Foundation. We run on sub-20ms block times and parallel execution to deliver real-time settlement, cross-margining, and modular vault strategies through a single self-custodial interface. Since launching mainnet, we have shipped a points program (Amps), a protocol-native stablecoin (usDCBL), and a multi-venue spot expansion. We compete directly with centralized exchanges on latency, depth, and product surface, and we are building the execution layer for global trading on Aptos. The role You'll join a small team of traders, quants, and developers, working closely together to design, build, and operate our trading infrastructure. In this role, you'll help to develop and maintain our market making, pricing, hedging, and monitoring systems, while also keeping a close eye on live performance and resolving issues in real time. What you will do Build and maintain market making, hedging, and inventory management systems across centralized venues and on-chain markets Write and ship production-grade code for execution, connectivity, monitoring, and PnL attribution Analyse trading performance and drive experimentation around parameter tuning, signal generation, and order placement logic, supported by rigorous backtesting. Monitor risk in real time across spot, perpetuals, and on-chain inventory, tightening the feedback loop between observed PnL and the underlying code Partner with our protocol and product teams on new launches, token listings, and evolving market structures What we are looking for 2 to 4 years at a TradFi prop, HFT, or top systematic fund in a quant dev, core dev, or trader-engineer seat Production-grade engineering chops across multiple of the following: Rust, C++, Java, Python. We expect strong Python plus real systems experience in at least one of Rust, C++, or Java Hands-on experience with order management systems, smart order routers, or execution engines in a low-latency environment Comfort reading exchange protocol docs, debugging connectivity at the network layer, and reasoning about latency budgets end-to-end Multi-venue portfolio and trading system experience and the ability to think clearly about inventory, hedging, and risk across more than one book Genuine intellectual interest in market microstructure: order book dynamics, queue position, adverse selection, fee tiers, maker/taker economics A portfolio: GitHub, writeups, side projects, internal tools, anything you can talk about in detail and defend Ability to overlap with at least one of SG, HK, or Tokyo trading hours Strong pluses Crypto or digital asset experience: market making on major CEX / DEX, or running on-chain strategies Familiarity with Aptos, Move, Solidity, or the mechanics of any on-chain perps venue Exposure to options market making Open source contributions to trading infrastructure, exchange SDKs, or DeFi protocols Crypto experience is welcome but not required; however, experience with HFT trading systems is essential How we work Small, senior team. You will own real surface area from week one. We ship aggressively, and treat the trading stack as a product. No quant research wall to throw ideas over, you do both. Direct feedback, short loops, no theater. Compensation Competitive base Meaningful token allocation Variable comp tied to delivery and team performance
