Requirements

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.

Nice To Haves

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.

Responsibilities

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.
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.
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.
