Senior Algo-Trading Developer JB-4874

The company is building a next-generation block builder that augments Ethereum’s capabilities, unlocks new DeFi

primitives, and improves neutrality while making block participation more accessible. As an Algo-Trading

Developer you’ll own and ship the protocol-facing trading infrastructure that converts quantitative ideas into real

on-chain performance: you’ll design and run ultra-low-latency Rust systems for statistical arbitrage, tune live

strategies using P&L and mempool feedback, build secure gas-efficient contract integrations, and operate the

end-to-end stack — directly shaping how execution and profitability work at the intersection of block building and

DeFi.

Required (must-have)

● Strong Rust expertise. ≥2 years shipping Rust in production; deep comfort with async, ownership,

lifetimes, profiling, and low-level optimizations.

● Extensive software engineering experience. ≥7 years delivering complex, high-impact systems.

● Background in HFT, market-making, proprietary trading, or real-time bidding.

● Proven low-latency systems experience. Built and tuned latency-sensitive pipelines (networking, packing,

thread/concurrency design, lock-free patterns, Linux perf).

● Operational discipline. Experience building monitoring and release processes, and running production

services (on-call experience).

● Product & outcome oriented. You care about profitability, maintainability, and moving the needle for

production systems.
