With a global reach with offices in London, New York, Manila, Barcelona and Montreal, we have a proven track record of delivering powerful, elegant and intuitive trading technology solutions. We are now looking for a Technical Business Analyst to join our team - someone who can bridge the gap between high-level product vision and detailed delivery execution in a complex, fast-moving technical environment. If you feel like this is you, you might be a perfect fit for this role! 🎉 YOU ARE: • A strategic thinker who can zoom out to understand the big picture and zoom in to nail the details. • A natural bridge-builder - equally comfortable in a room full of engineers and a room full of stakeholders. • A problem-solver who thrives in ambiguity and brings calm, clarity, and structure to complex situations. • A curious mind who genuinely enjoys understanding how systems work, not just what they need to do. • A collaborative team player who believes the best solutions come from diverse perspectives. YOU HAVE: • A background as a software engineer (ideally a senior Java developer) who has moved, or wants to move, into a technical business analysis role. • A strong technical and domain-driven mindset, with the ability to work closely with engineering teams. • Hands-on experience with high-performance messaging or sequencing platforms such as Aeron, Kafka, Hydra, or equivalent - including an understanding of message ordering, state machine replication, and fault-tolerant distributed systems • Demonstrable exposure to low-latency or high-throughput messaging infrastructure in a financial or similarly demanding technical environment • Experience in QA, Software Engineering, Technical Business Analysis, or another highly technical product environment. • A product-first mindset, combining Domain-Driven Design principles with a deep understanding of systems and user impact. • The ability to define and document functional and non-functional requirements clearly and effectively. • An understanding of performance, scalability, resilience, and availability in modern platforms. • Experience working in Agile or Kanban environments across the full software development lifecycle. • Confidence contributing to architecture and design discussions, simplifying complex challenges into deliverable solutions. • The ability to create process flows , sequencing diagrams, and documentation that align technical and operational teams. YOU WILL: DRIVE CLARITY IN COMPLEX ENVIRONMENTS: • Operate confidently in ambiguous situations, shaping requirements and driving alignment with minimal direction. • Adapt to different delivery models across products, including engineering-led and BA-led ways of working. • Define and maintain functional and non-functional requirements - including operational scenarios, acceptance criteria, and QA validation needs across distributed workflows • Ask the right questions early, so that solutions are well understood, well defined, and ready to be delivered. SHAPE THE BACKLOG AND DELIVERY: • Collaborate with engineering, QA, and architecture teams to translate complex technical solutions into structured backlog items, deliverable stories, and testable outcomes. • Help stakeholders make their vision for the product materialise, especially in the early stages of each delivery phase. • Be the stakeholders' proxy in the team - able to make quick, firm decisions on scope, requirements and prioritisation/triage. • Drive backlog review and estimation processes, and take part in planning activities. • Define acceptance criteria and tests up front as part of a Business-Driven Development approach. • Follow up during implementation and testing phases to ensure delivery satisfies requirements. COLLABORATE ACROSS THE TEAM: • Work closely with QA to assess failure scenarios and help distinguish bugs, enhancements, and new feature requirements. • Facilitate discussions across technical and business stakeholders to drive clarity, alignment, and sound decision-making. • Support delivery, implementation, and release processes, ensuring solutions align with business objectives, customer use cases, and non-functional expectations. • Help improve operational processes and workflows - both internally and externally - bringing a calm, pragmatic and collaborative approach.
