Start with a chat, not a search bar
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.
What we’re looking for:
- Minimum 4 years’ commercial software development experience
- Strong commercial Java development experience – this is essential
- Excellent understanding of software engineering fundamentals
- Experience designing and building distributed, scalable applications
- Strong knowledge of data structures, algorithms, and object-oriented development
- Experience developing performance-focused, production-grade software
- Strong problem-solving and analytical skills
- Degree in Computer Science, Computer Engineering, or a related technical discipline, or equivalent experience
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Highly desirable:
- Experience with highly concurrent or distributed systems
- Low-latency or high-transaction environments
- Python, Go, or C++ experience alongside Java

You do not need previous financial services experience. We are particularly interested in talented Java engineers from technically demanding environments who are keen to apply their skills to complex trading technology.
