Job description

London | Permanent

I’m working on a new opportunity for an experienced kdb+ engineer to join a highly technical team building data platforms used across global financial markets.

This is a senior, hands-on position where you’ll work on complex real-time and historical data problems, take ownership of technical delivery and have a genuine say in how kdb+ platforms are designed and built.

You’ll be working closely with people across trading, quantitative and technology teams, so I’m looking for someone who combines strong kdb+/q engineering with a good understanding of how financial markets operate.

What I’m looking for:

• Experience building production-grade kdb+ platforms
• Good understanding of real-time, historical and time-series data
• Strong Linux/Unix knowledge
• Experience within capital markets, investment banking or trading environments
• Comfortable taking ownership of design and technical decisions
• Ability to work directly with both technical and business stakeholders
• Experience supporting or mentoring other engineers

Experience with Python, cloud technologies, tick data, electronic trading or AI development tooling would be a bonus.

It’s a strong opportunity for someone who wants to remain hands-on technically while taking on more ownership and working on some genuinely challenging data problems within financial markets.
