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 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.
