Market Data Engineer (Python) | Systematic Trading

Direct message the job poster from Selby Jennings


A leading global investment firm is seeking a Market Data Engineer to join its London-based team and help build robust, scalable tick data infrastructure that powers systematic trading strategies across asset classes. This is a high-impact engineering role focused on designing and optimizing real-time and historical market data pipelines in a cloud-native environment.


You’ll work closely with trading and quant teams to ensure data is clean, fast, and accessible - enabling research, signal generation, and execution at scale.


What You’ll Do

  • Build and maintain high-performance tick data pipelines for ingesting, processing, and storing large volumes of market data.
  • Work with time-series databases (e.g., KDB, OneTick) and Parquet-based file storage to optimize data access and retrieval.
  • Design scalable cloud-native solutions (AWS preferred) for market data ingestion and distribution.
  • (Bonus) Integrate Apache Iceberg for large-scale data lake management and versioned data workflows.
  • Collaborate with trading and engineering teams to define data requirements and deliver production-grade solutions.
  • Implement robust data validation, monitoring, and error handling to ensure data integrity and uptime.
  • Continuously improve latency, throughput, and scalability to support high-frequency trading environments.

What You Bring

  • 4+ years of experience in software engineering, with a focus on market data systems.
  • Strong Python skills and familiarity with cloud platforms (AWS, GCP, or Azure).
  • Experience with tick data and building tick data pipelines.
  • Proficiency with Parquet-based file storage; Iceberg experience is a plus.
  • Familiarity with Kubernetes, containerization, and modern orchestration tools.
  • Experience with time-series databases (KDB, OneTick) and C++ is a plus.
  • Strong problem-solving skills and a collaborative mindset.
  • Understanding of financial markets and trading concepts is beneficial.

This is a chance to build foundational infrastructure that directly supports alpha generation. You’ll work in a fast-paced, collaborative environment where engineering excellence drives trading performance.


If you’re passionate about market data, scalable systems, and working at the core of systematic investing - we’d love to hear from you.

Why Machine Learning Careers in the UK Are Becoming More Multidisciplinary

Machine learning (ML) has moved from research labs into mainstream UK businesses. From healthcare diagnostics to fraud detection, autonomous vehicles to recommendation engines, ML underpins critical services and consumer experiences. But the skillset required of today’s machine learning professionals is no longer purely technical. Employers increasingly seek multidisciplinary expertise: not only coding, algorithms & statistics, but also knowledge of law, ethics, psychology, linguistics & design. This article explores why UK machine learning careers are becoming more multidisciplinary, how these fields intersect with ML roles, and what both job-seekers & employers need to understand to succeed in a rapidly changing landscape.
