Founding Principal Engineer

Full-time/Company: Joyride

Joyride is building the first dedicated 0DTE options exchange to provide better leverage for crypto traders. Derivatives present the single largest opportunity to bring traditional finance on-chain with over $3.5 trillion dollars of notional volume traded in the U.S. every day. 

What you will build:

The Trusted Matching Engine: Architect a high-frequency Central Limit Order Book (CLOB). It must handle massive throughput without the latency drag of a blockchain while maintaining verifiability.

The Trust Bridge: Design the cryptographic system that proves to the blockchain that the off-chain match was valid. We must ensure that the exchange operators cannot front-run or alter the order book.

Atomic Settlement: Write the programs that handle the movement of collateral based on the proofs generated by your off-chain engine.

Risk & Liquidation: Build a real-time risk engine capable of liquidating 0DTE positions instantly to protect the protocol from bad debt, even during high network congestion.

Who you are:

High-Performance Systems Expert: You understand exactly how your code maps to hardware. You prioritize memory layouts, lock-free data structures, and concurrency patterns to squeeze every cycle out of the CPU.

Architectural Polymath: You are comfortable traversing the gap between high-performance cloud infrastructure and trustless state machines.

Security Minded: You think like an adversary. When you see a “hybrid” architecture, your first thought is “How do I break the link between the server and the chain?”

Requirements:

- 5+ years of backend systems engineering (Rust, C++, or Go)
- Deep proficiency with Rust
- Familiarity with Solana and EVM development
- Knowledge of event-driven architectures and asynchronous programming
- Experience designing hybrid architecture
- Strong grasp of applied cryptography

Bonus:

- Experience building trading systems (matching engines, risk management)
- Background in high-frequency trading or financial engineering
- Previous work on a centralized exchange or CLOB DEX

What we offer:

Competitive salary and upside
Remote work flexibility
Autonomy to solve challenging problems
Fast-paced environment
Unlimited growth potential
Support for open-source contributions
