Senior KDB Developer - London
The best kdb+ talent isn't usually actively applying for jobs.
They're busy solving complex problems, building scalable real-time systems, and making critical architectural decisions that power some of the world's fastest-moving financial environments.
If that's you, or if you've started thinking about what your next move could look like later this year, this opportunity is worth a conversation.
We're partnering with a highly respected financial technology organisation investing heavily in its market data and analytics platforms. It's an opportunity to join a business where kdb+ sits at the heart of the platform and where your expertise will directly influence design decisions, performance improvements, and the direction of the wider engineering team.
What You'll Be Doing
- Designing and evolving enterprise-scale kdb+ architectures
- Building highly performant, resilient time-series data solutions
- Working with vast volumes of real-time and historical market data
- Driving technical decisions and influencing architecture strategy
- Collaborating with senior stakeholders across technology and the business
- Mentoring engineers and helping shape engineering best practices
- Leading initiatives focused on scalability, performance, and innovation

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.

- Deep expertise in q and time-series databases
- Proven experience designing and scaling production kdb+ environments

Why This Role?
The kdb+ market is small. Great opportunities are even smaller.
If you've reached the point where you're looking for:
- More influence over technical direction
- Larger-scale engineering challenges

- A stronger engineering culture
- The chance to work alongside some of the brightest kdb+ specialists in the market
Then this could be the right next step.
