Meet the Team

Information Technology is central to the health and growth of Millennium’s active, multi-manager business model, which requires flexible, scalable technology and advanced proprietary systems. The KDB Development team builds and operates high-performance time-series data platforms using kdb+ and q, with a focus on the architecture, performance, reliability, and usability of real-time and historical databases. The team also supports accessible analytics interfaces, including Jupyter notebooks, and partners closely with trading, research, data, and infrastructure stakeholders.

What You'll Do

  • Lead, mentor, and develop a team of KDB/q engineers, establishing clear priorities, engineering standards, accountability, and ownership.
  • Own the architecture and roadmap for kdb+ real-time and historical database platforms, including data ingestion, intraday processing, end-of-day workflows, storage, retention, recovery, and query access.
  • Design and implement scalable q solutions for high-volume real-time and historical time-series data, with a focus on performance, reliability, and maintainability.
  • Drive performance tuning across memory management, database partitioning and sym attributes, query patterns, indexing, process communication, and capacity planning.
  • Build and maintain analyst-facing data-access tooling, including Jupyter notebook environments, q/Python integrations, reusable notebooks, and supported query libraries.
  • Establish engineering best practices for code quality, automated testing, source control, CI/CD, release management, documentation, monitoring, and incident response.
  • Embed data-quality controls, reconciliation processes, entitlements, auditability, and retention policies into platform design.
  • Partner with trading, quantitative research, operations, data engineering, and infrastructure teams to deliver durable solutions; lead design and code reviews, production support, and continuous improvements following incidents.

What You Bring

  • Significant experience developing and operating production systems using kdb+ and q, including the design, support, and tuning of real-time and historical database architectures.
  • Expertise in real-time data ingestion, tickerplant-based or comparable streaming architectures, intraday recovery, end-of-day processing, and historical data management.
  • Strong command of time-series data design, high-performance q queries, partitioned databases, memory management, and operational performance troubleshooting.
  • Experience delivering analytical workflows through Jupyter notebooks, including q/Python interoperability and well-governed self-service data access.
  • Demonstrated technical leadership and experience guiding engineers through delivery as a people manager, team lead, or senior technical lead.
  • Strong software engineering discipline, including testing, code review, CI/CD, version control, and production release practices.
  • Experience integrating KDB with adjacent technologies such as Python, Java, C++, APIs, messaging platforms including Solace or Kafka, and infrastructure tooling.
  • Clear written and verbal communication skills, with the ability to partner effectively with technical and non-technical stakeholders in high-throughput, latency-sensitive environments.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
