Group Details

We're hiring a Senior Java Engineer. 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. Your work spans market-data ingest, strategy decisioning, order routing, and gateway egress - all under microsecond-to-low-millisecond budgets.

Asset coverage: fixed income is our anchor today, with an active roadmap to expand the platform across additional asset classes - listed derivatives, FX, crypto, and others as the business grows.

Tradeweb Technology jobs are fully remote. The Tradeweb Technology hub is in our Jersey City office which can be used for team meetings and collaboration efforts.  There may be days where travel to the Jersey City office is recommended for organizational off sites.

Job 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.

Qualifications

• 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.

Preferred 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.
