Requirement

We are looking for engineers who combine deep technical craft with genuine capital markets domain knowledge The two are equally important candidates who have one without the other are unlikely to be effective in this environment

Test Driven Development is nonnegotiable Engineers must be practitioners of TDD not just advocates and are expected to own the quality of their deliverables end to end rather than outsourcing it to a separate QA group We expect candidates to demonstrate this through their approach to design not just their ability to write tests after the fact This will be assessed at interview

Java expert level primary delivery language

Event driven architecture practical experience designing and building systems on message passing and event sourcing patterns including failure handling ordering guarantees and replay semantics

Agile delivery strong preference for engineers who have worked in genuine iterative delivery environments with short feedback loops not waterfall projects labelled as agile This includes a focus on Continuous Integration Delivery using techniques such as trunk based development and achieving frequent 1 per week production releases during regular business hours without any service interruption


Domain Experience

Candidates must have hands on experience working in or alongside a capital markets trading or post trade environment Crucially we seek engineers who are proactive in developing deep domain knowledge themselves rather than solely relying on Business Analysts for this expertise The following are indicators of the required depth not an exhaustive list

In depth understanding of the trade lifecycle including Trade Booking and Position Management principles

Practical experience with post trade operations such as Cashflow Calculation Settlement Wires Client Reporting and Accounting principles

Familiarity with corporate actions regulatory reporting and integrating with risk valuation systems in an equities context

Understanding of Prime Brokerage Synthetic Swap or Cash Equity operational flows is a significant advantage

Exposure to regulatory reporting obligations in a financial context eg 871m EMIR MiFID is advantageous

Candidates should be able to demonstrate this experience at interview with concrete examples not high level familiarity
