emagine is a high-end professional services consultancy and solutions firm specialising in providing business and technology services to the financial services sector. We build genuine relationships and partnerships, and are committed to delivering exceptional service while fostering a positive and equitable working environment with our consultants and colleagues.

This role is a front-office aligned position, with engineers embedded on the trading floor, working alongside traders and quants to deliver low-latency, high-impact systems across both flow and structured/exotic derivatives. The role is ideal for engineers who enjoy operating close to the business, owning features across the full technology stack, in a fast-paced, iterative front-office environment.

• Design and develop bespoke front-office applications supporting Equity Derivatives trading and structuring
• Deliver full-stack functionality, spanning: backend services and APIs, event-driven components, real-time user interfaces for traders
• Work closely with traders, quants, and fellow technologists to translate trading requirements into robust production solutions
• Contribute to the evolution of scalable, low-latency architectures supporting flow and structured/exotic derivatives
• Take ownership of features from design through to deployment and production support
• Operate effectively in a trading floor environment, responding quickly to feedback and change

• Strong full-stack engineering background
• 5+ years’ experience in a strongly typed language such as Java or C#
• Commercial experience with React building complex, data-driven UIs
• Around 1+ year of professional Python experience (in addition to Java/C# background)
• Experience building and supporting production-grade systems in demanding environments
• Comfortable working as a polyglot engineer, owning features end to end

This role favors engineers with a strong enterprise language foundation (Java/C#) combined with Python, rather than Python-only profiles.

The ideal consultants will share our values and be aligned with our ways of working and, as your career progresses, you can expect to work across all areas of the project lifecycle.

• Providing our people with a supportive culture, rooted in our values and driven by our purpose
• Promoting inclusion, collaboration, well-being, and learning and development
• Providing increased agility and flexibility within our hybrid working model
• Investing in employees’ growth through ongoing training and development
• Autonomy to take ownership of projects and demonstrate individual expertise
