Job Specifications
We are seeking multiple experienced Contract Core Server-Side Java Developer to a prestigious Tier 1 investment bank, supporting their high-performing Equity Swaps business.
This is an exciting opportunity to be part of a dynamic global front-office team, responsible for developing cutting-edge software for one of the world's leading providers of Equity Swap products.
In this role, you'll work on the real-time calculation engine and its critical components—the very core of the product suite—driving innovation in a fast-paced, high-impact environment. If you’re passionate about building robust, scalable solutions and thrive in a challenging, high-stakes setting, this is the perfect opportunity to make your mark.
Primary Responsibilities
The developer will work within an agile squad developing within a system comprising of numerous Java services that interact via messaging to produce the product outputs in real time. Technologies and techniques such as highly multi-threaded Java, Sharded Mongo DB and caching are used in the stack to provide the scale and performance that the product requires. A candidate is likely to gain exposure to both new and complex technologies as well as in-depth business knowledge. The candidate should possess good analytical skills, strong software engineering skills, a logical approach to problem solving, be able to work in a fast paced environment liaising with demanding stakeholders to understand complex requirements and be able to prioritize work under pressure with minimal supervision. The candidate should be a problem solver, and be able to bring with them some positivity and enthusiasm in trying to think about and offer potential solutions for architectural considerations. We are looking for someone to help own problems and be able to demonstrate leadership and responsibility for the delivery of new features. As part of the development cycle, you would be expected to write quality unit tests, supply documentation if relevant for new feature build outs, and be involved in the test cycle, including proposing how an item can be automatically tested (and potentially deployed) within our pipeline. Although the role is predominantly Java, we require someone who is flexible with the development environment; although Java is the majority skill, some days you might be writing Java, and other days you might need to tune a stored procedures or tweak a script. You would be expected to get involved in the Level 3 production support rota which is shared between our developers globally. Although we have a dedicated release team, you may need to occasionally help with weekend deployment activities. The role is ideal for someone looking for a strong career development path with many opportunities to grow, learn and develop. The role requires someone who is flexible and able to respond to a dynamic business environment. The candidate must be adaptable to work across multiple technologies and disciplines, with a focus on delivering quality solutions for the business in a timely fashion.
