Senior Algo-Trading Developer, TLV, 1d Remote

Location: Tel Aviv — hybrid (4 days in office / 1 day remote)

Why join us

We are building a next-generation block builder that augments Ethereums capabilities, unlocks new DeFi
primitives, and improves neutrality while making block participation more accessible. As an Algo-Trading
Developer youll own and ship the protocol-facing trading infrastructure that converts quantitative ideas into real
on-chain performance: youll 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.

What youll build

A state-of-the-art statistical trading bot and the execution platform that powers it: a production-grade Rust trading
engine, ultra-low-latency network and signing paths, mempool monitoring and deterministic submission logic,
robust gas/nonce management and contract adapters for efficient settlement, and comprehensive monitoring,
automated risk controls and runbooks for on-call operation. Crucially, youll prototype and deploy new trading
primitives that rely on our builders augmented capabilities — enabling novel execution patterns that arent possible
on standard infrastructure.

What youll own

You will work on the architecture, implementation, and live operation of our autonomous trading stack — from
signals to settlement — collaborating closely with quants, product and platform engineers:
Ship the core trading engine in Rust. Implement signal processing, order management, execution, and
risk modules with high reliability and low-latency performance.
Run the bot in production and iterate quickly. Respond to live feedback (P&L, slippage, failed
transactions, mempool dynamics), instrument systems, debug root causes, and deploy fixes/strategy tweaks
rapidly.
Design execution primitives and infra. Build ultra-low-latency paths (network, serialization, signing,
mempool monitoring, gas and nonce management) with deterministic, auditable behavior under trading
pressure.
Innovate trading strategies & executors. Translate quantitative ideas into production code; experiment
with MEV, on-chain arbitrage, intrablock execution, and JIT liquidity techniques.
Monitoring and Production Responsibility. You will be responsible for the production environment. This
includes building solid monitoring, automated risk controls, clear alerts, and on-call procedures to ensure
our autonomous systems are safe and reliable.
Integrate with EVM ecosystems. Implement secure, gas-efficient smart-contract integrations and
transaction lifecycle flows. Work with Foundry/Hardhat, Solidity contracts, and EVM internals to reduce
on-chain cost and risk.

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.
