Job description

Senior Technical Business Analyst - Financial Banking

Candidates will come from highly technical background with a track record of delivering complex, low-level code systems (e.g. C++, Java), with strong knowledge of performance optimisation and latency management along with networking (TCP, UDP, multicast) and low-latency data distribution.

Ideally these skills will have been gained in a low latency financial/banking/trading arena with some business knowledge (equities, fixed income, futures & options) but candidates from other domains such as streaming, telecoms, defence and gaming, where latency is a priority, will also be considered.

Responsibilities and Duties

• Requirements gathering - Work closely with other product managers, developers and architects to translate business needs into clear, technically robust specifications, identifying dependencies, interfaces, and technical constraints.
• Technical roadmap ownership - Work with architects and engineers to maintain the technical roadmap, identifying areas of technical debt or new application components across distributed systems.
• Technical documentation - Produce and maintain detailed technical and functional documentation, including API specifications, configuration workflows, and integration guides.
• Stakeholder engagement - Act as a central communication point between product, engineering, infrastructure, and operations, ensuring alignment of objectives and expectations.
• Process improvement - Identify inefficiencies in workflows, proposing automation or process improvements.
• Project management - Drive delivery of software and hardware initiatives, managing scope, timelines, and dependencies across cross-functional teams.
• Risk assessment - Anticipate technical and operational risks to delivery, proposing mitigations early in the project lifecycle.

Required Skills/Experience

The successful candidate will have a strong and positive work ethic with the ability to forge lasting relationships (both internal and external) at all levels. The appetite and ability to learn in the role is a must.

Essential

• Proven track record of specifying and delivering complex, low-level code systems (e.g. C++, Java), with strong knowledge of performance optimisation, latency management, concurrency, and integration considerations.
• Strong knowledge of networking principles (TCP, UDP, multicast) and experience designing for resilience, throughput, and low-latency data distribution.
• Expertise in distributed computing and system architectures, including microservices and high-throughput, low-latency systems.
• Strong knowledge of data architecture and database design, with experience across relational, time-series, and high-availability database environments.
• Understanding of on-premises Linux-based infrastructure, and deploying and managing containerised/virtualised environments (AWS, OpenShift).
• Demonstrated ability to work within Agile/Scrum SDLC, translating business objectives into actionable user stories and robust technical deliverables.
• Proven ability to produce and maintain high-quality technical documentation and API specifications suitable for both engineering and client consumption.

Desirable

• Experience working with an electronically traded asset class.
• Strong business and technical understanding of exchange-based order book methodologies such as CLOB, auctions, dark trading, pegged orders and more.
• Familiarity with FIX trading protocol and market data systems.
• Experience working in a highly regulated environment.
