The Role

Join our dynamic Core Technology team as a Software Developer, where you'll play a crucial role in building and enhancing the software that drives both our Asset Management and Securities businesses. You’ll work closely with Operations, Treasury, Risk, Compliance, Finance, and Client Services—embedded alongside these teams to deeply understand their challenges and anticipate their needs.

You’ll also collaborate with trading teams to ensure new strategies and markets are fully supported. Our mission is to deliver innovative, high-impact technology solutions that streamline processes, enhance decision making, and drive efficiency across the business. We also own the firm’s AI roadmap, integrating frontier models and capabilities where they deliver real value.

This is a hands-on, full-stack role working with Java and Python, where you'll design and develop cutting edge solutions while also empowering analysts to elevate their data science and development capabilities. You’ll collaborate with a supportive team while taking ownership of projects—from initial scoping and architecture to development and deployment—solving complex problems and driving meaningful change. If you're passionate about technology, thrive in a fast-paced, collaborative environment, and want to build software that makes a real difference, we'd love to hear from you!

Requirements:

• Strong software development skills with expertise in Java, capable of writing high-quality, well structured, well-tested code.
• A keen interest in financial markets and the trading lifecycle, with a proactive approach to learning new concepts.
• Excellent communication skills (both written and verbal), with the ability to collaborate effectively across technical and non-technical teams.

Preferred:

• Experience with Python, C#
• Hands-on experience working with relational databases, including schema design, query optimization, and performance tuning.
• Familiarity with data science principles and methodologies, with experience applying them in real-world scenarios.
• Experience with our core stack, including Hibernate, PostgreSQL, Maven, Guice, NumPy, and Pandas.
• Exposure to financial markets, either through formal education or professional experience

The Role

Within iSAM Securities, the Bridge front office team develops and supports an MT4/MT5/FIX bridge using sophisticated proprietary pricing, execution, and liquidity management solutions.

We are currently undergoing a major re-engineering of this product and are looking for a mid-level Java developer (5–10 years’ experience) to join our London team. We recruit engineers who take pride in building robust systems and are comfortable taking ownership in a demanding environment.

We are a small team and we adopt a lean, rapid development cycle, so an open mind and willingness to learn are essential. We are agile in spirit, but we don’t follow any ceremonies. We strongly believe in the power of collaboration, so the right personality is just as important as technical skills for this role (and for the Company in general).

We are looking for a strong backend engineer who also takes an interest in the end product, including how it is used and presented. Depth in backend development is essential; front-end involvement is expected, but not at the expense of core engineering quality. In this sense, this is not a traditional “full-stack” position. Candidates primarily focused on front-end development are unlikely to be a good fit.

Whilst this is primarily a development role, you will be expected to actively support production systems within a support rota. Finally, please note that this is an office-based position.

Required

• Strong developers with excellent Java, Linux (scripting and command line), and SQL database skills. Proven ability to deliver well-tested, quality software.
• A genuine interest in front-end development, with an eye for usability and clarity. You don’t need to be a front-end specialist, but you should care about how systems are presented and used, not just how they are built. Experience with modern JavaScript frameworks (we use React) is a strong plus.
• Willingness and ability to quickly learn new languages and technologies.
• Ability to design APIs with front-end consumers in mind.
• Comfort debugging issues across the stack (UI, API, database).
• Interest in trading and execution, a capacity to take on a variety of work.
• Strong communication skills, attention to detail, and the ability to adapt to a constantly changing financial environment.

Preferred

• Experience with React or similar frameworks, including component-based design and state management.
• A pragmatic sense of UI/UX: you recognise good interfaces and know how to create one.
• Exposure to trading systems or financial markets.
