High-Growth Fintech – Asset Management Software
London (Hybrid – 2 days in office/week)
Quant Capital is urgently looking for a Core Java Developer to join a innovative FinTech business developing next-generation asset management platforms for professional investors. The firm operates as a lean, high-performance engineering team focused on solving complex industry problems through clean, scalable code and modern infrastructure.
We’re looking for a Java Developer who’s ready to work across the stack and get deeply involved in architectural design, backend performance, and infrastructure scaling.
Role Overview
This is a hands-on software engineering role in a startup-style environment, ideal for someone who enjoys technical autonomy, rapid iteration, and product ownership. You’ll work directly with experienced engineers and stakeholders to enhance a cutting-edge platform used by institutional clients.
Key Responsibilities
* Design, build, and maintain high-performance backend services using Core Java
* Collaborate closely with a compact, highly capable development team
* Optimize software performance and troubleshoot production issues across the stack
* Follow clean coding standards and lead on testing, CI/CD, and DevOps best practices
* Participate in technical architecture discussions, code reviews, and product planning
* Contribute to front-end components and help shape the broader system architecture
Required Skills & Experience
* Strong proficiency in Core Java with sound understanding of system and object-oriented design
* Solid experience designing and developing scalable distributed systems
* Understanding of front-end frameworks (React, Angular, or similar) is a plus
* Familiarity with SQL/NoSQL databases and experience in data modelling
* Exposure to cloud platforms (AWS preferred) and modern DevOps workflows
* Comfortable working in a fast-moving, collaborative environment
* Financial sector or asset management knowledge is a bonus, not a must
Why Apply?
* Make a direct impact – Work on core features in a live, client-facing platform from day one.
* Full-stack opportunities – While Java is the focus, there’s room to contribute across front-end and infrastructure layers.
* Lean, engineering-led culture – Collaborate directly with founders and senior engineers in a fast-paced, low-bureaucracy setup.
* Modern stack, modern problems – Tackle real-world performance and scaling challenges in asset management technology.
* Clear growth path – The team is small, the work is meaningful, and high performers are quickly recognized and rewarded.
