Project description
We are seeking an experienced Senior KDB+ Developer to design, develop and optimize high performance data platforms built on kdb+. The ideal candidate will have deep expertise in kdb+ tick architecture, performance tuning at scale and close collaboration with business stakeholders—particularly within Risk functions—to deliver robust, efficient and maintainable solutions.
Responsibilities
* Design, develop and maintain kdb+ tick systems with strong understanding of data organization, schema design and the performance implications of different architectural approaches.
* Build and operate solutions handling large‑scale, high‑frequency datasets, ensuring low latency, high throughput and efficient memory usage.
* Analyze and optimize q queries, data models and ingestion pipelines for both real‑time and historical workloads.
* Collaborate closely with Risk function teams to translate business requirements into efficient, scalable and performant code.
* Drive continuous improvement through refactoring, performance benchmarking and adoption of best practices.
* Mentor and guide junior and mid‑level developers, fostering a culture of technical excellence, code quality and knowledge sharing.
* Participate in design reviews, production support and root‑cause analysis of complex system issues.
* Work collaboratively within an Agile or iterative delivery environment, contributing to design, implementation, testing and release phases.
Skills
Must have
* 8+ years of hands-on experience in kdb+ development in a production environment.
* Strong expertise in q language including: table design (splayed, partitioned, segmented), in‑memory vs on‑disk trade‑offs, efficient joins, aggregation and windowed analytics.
* Deep understanding of kdb+ tick architecture including ticker plant, RDB, HDB and associated patterns.
* Proven experience working with large datasets and optimising queries for performance and scalability.
* Strong background in Unix/Linux environments, including shell scripting for automation, monitoring and operational tooling.
* Solid understanding of software delivery processes and methodologies (Agile, CI/CD, version control, release).
* Ability to communicate clearly with both technical and non‑technical stakeholders, demonstrating systematic reasoning and problem‑solving skills.
Nice to have
* Knowledge of inter‑process communication mechanisms in kdb+ and integration with external systems.
* Experience tuning kdb+ systems for low‑latency and high availability.
* Familiarity with data quality checks, validation frameworks and operational resilience patterns.
* Exposure to financial markets data (market data, trading, risk, post‑trade workflows, equity asset class).
* Passion for writing clean, efficient and well‑structured code.
