Original job description

About Decibel

Decibel is a high-performance, fully on-chain trading platform built in collaboration with Aptos Labs and the Decibel Foundation. Designed to match the speed of high performance trading, Decibel offers spot, perpetuals, and yield products through a unified, self-custodial interface. The platform runs on the Aptos blockchain, leveraging its sub-20ms block times and parallel execution to support real-time settlement, cross-margining, and modular vault strategies. Decibel aims to serve as the execution layer for the Aptos global trading engine, empowering traders, developers, and institutions with scalable, composable financial infrastructure.

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

Our Benefits

Insurance premium coverage
Flexible vacation time
Competitive Salary
Protocol Token Grants
