Senior Java Algo Developer

Role Overview

Tradeweb is hiring a Senior Java Algo Developer / Senior Java Engineer for a highly hands-on role focused on building and operating algorithmic trading systems. You will write production code daily, optimize performance-critical “hot paths,” and design algorithm containers and an end-to-end low-latency algo pipeline.

Responsibilities

• Own latency and throughput end-to-end from market-data ingest → strategy decisioning → gateway egress, setting and measuring performance budgets.
• Design and implement new algorithmic order types and synthetic multi-leg execution logic (fixed income is the current anchor).
• Profile and tune the JVM hot path, including:
  • GC behavior and allocation patterns
  • lock-free concurrency
  • off-heap memory
  • “mechanical sympathy” for performance
  • Daily use of tools like JFR, async-profiler, and flame graphs.
• Operate the algo pipeline, including:
  • version control
  • certification harness
  • backtesting and shadow-trading frameworks
  • post-trade analytics for strategy health
• Partner with the in-house quant team to translate signals/research into deterministic, production-grade execution code (you don’t need to be a quant, but must work fluently with them).
• Maintain venue connectivity across FIX-based client gateways, exchange/direct integrations, ECN/venue connectors, and new asset-class connectivity.
• Modernize legacy Java services from Java 8 to current LTS.

Asset Coverage / Scope

• Fixed income is the anchor, with an active roadmap to expand into listed derivatives, FX, crypto, and other asset classes.
• Work must meet microsecond-to-low-millisecond performance budgets.

Location & Work Model

• Fully remote for Tradeweb Technology roles.
• Team hub is Jersey City; occasional in-person days may occur for off-sites and collaboration.

Requirements

• Strong ability to optimize production Java systems for latency/throughput.
• Fluency with JVM performance engineering (GC, allocations, concurrency, off-heap).
• Experience designing and operating algorithmic execution pipelines and certification/backtesting/shadow-trading processes.
• Ability to collaborate effectively with quant researchers and translate research into deterministic execution code.
• Experience with FIX/venue connectivity and trading integrations.
• Experience modernizing/upgrading Java 8 to current LTS.

Nice-to-Haves (from the posting)

• Hands-on familiarity with JFR, async-profiler, and flame graphs.
• Experience with JVM lock-free concurrency and off-heap memory.
• Experience expanding platforms to new asset classes.
