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.

• 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).
