Senior Java Algo Developer

About the role

This is a highly hands-on role where you'll be writing production code alongside the team every day. You'll spend most of your time optimizing hot paths, designing new algorithm containers, and improving end-to-end latency. You will also own the algo pipeline: how strategies move from research and calibration through certification and into production.

Responsibilities

• Own latency and throughput end-to-end — from market-data ingest through strategy decisioning to gateway egress. You set the bar and the budgets, and you measure them.
• Design and implement new algorithmic order types and synthetic multi-leg execution logic, with fixed income as the current anchor and new asset classes coming online as the roadmap expands.
• Profile and tune the JVM hot path — GC behavior, allocation patterns, lock-free concurrency, off-heap memory, mechanical sympathy. JFR / async-profiler / flame graphs are daily tools.
• Operate the algo pipeline — version control, certification harness, backtesting and shadow-trading frameworks, and post-trade analytics for strategy health.
• Partner with our in-house quant team — translate their signals and research into algorithmic designs and deterministic, production-grade execution code. You don’t need to be a quant; you need to work fluently with them.
• Maintain venue connectivity — FIX-based client gateways, exchange-direct integrations, ECN and venue connectors, and new asset-class connectivity as the platform expands.
• Modernize legacy services from Java 8 onto current LTS — sequence the migration without disrupting trading flow and bring older modules onto the same standards as the rest of the platform.

Requirements

• 8+ years building production Java systems, with at least 4 years in latency-sensitive trading infrastructure (HFT, market making, execution algos, low-latency OMS/EMS, or equivalent).
• Demonstrated JVM optimization for microsecond-to-low-millisecond latency budgets: GC tuning (G1, ZGC, Shenandoah, or Azul Zing), JIT behavior, escape analysis, allocation profiling, and lock-free concurrency primitives.
• Deep experience with high-performance messaging and IPC — Aeron, Chronicle Queue / Chronicle Map, LMAX Disruptor, or equivalent — and binary wire formats such as SBE, FlatBuffers, or proprietary.
• Production FIX experience across 4.2, 4.4, 5.0 SP2, and FIXT, with hands-on use of a Java FIX engine (QuickFIX/J, Fix Antenna, or proprietary).
• Comfortable extending custom tags and managing session-level concerns.
• Tick-store / time-series market-data systems — capture, persistence, deterministic replay, and use in research and backtesting workflows.
• Complex-event-processing (CEP) for strategy hosting — instrument lifecycle, order state machines, leg-by-leg synthetic execution, and deterministic strategy containers.
• Exchange-grade order management and execution — OMS/EMS internals, smart order routing, pre-trade risk (limit checks, fat-finger guards, kill switches), and post-trade reconciliation.
• Working familiarity with C# / .NET — several adjacent tools in our stack are .NET-based; you can read, debug, and occasionally contribute.

Qualifications

• Institutional electronic trading across multiple asset classes — fixed income, listed derivatives, equities, FX, or crypto.
• Breadth across asset classes is a meaningful plus.
• Crypto execution experience: spot connectivity (Coinbase, Binance, OKX, Kraken), CEX/DEX routing, perpetual futures, or basis trading across venues.
• Hands-on colo operations in major financial data centers (e.g., AUR, NY4, LD4, TY3, FR2).
• Exchange-direct market data and order entry: CME MDP3 / iLink, ICE eFix, Eurex ETI/EOBI, NASDAQ ITCH/OUCH, or equivalent venue-native protocols.
• Kernel-bypass networking (Solarflare/Onload, DPDK, eBPF) and OS-level tuning — CPU isolation, IRQ pinning, hugepages, NUMA awareness.
• Experience with deterministic simulation, event-driven backtesting frameworks, and TCA / execution-quality measurement.
