The Opportunity

- Own the Feature Lifecycle: Lead the end-to-end delivery of complex investigation features, from initial business discovery with stakeholders to final technical rollout.
- Design Seamless Client Journeys: Define and design end-to-end client and user journeys across the platform, ensuring flows are intuitive, uninterrupted, and optimised for investigation efficiency, while minimising friction for users.
- Own Problem Discovery, Not Just Delivery: Proactively identify user pain points, inefficiencies, and hidden risks within workflows, and propose data-driven solutions to improve both user experience and business outcomes.
- Translate Business into Scalable Systems: Balance business and system thinking, translating high-level business intent into end-to-end flows and developer-ready specifications, including OpenAPI (Swagger) specs, JSON Schemas, and UML Sequence Diagrams.
- Architect Technical Solutions: Design logic, define service responsibilities, map out data flows, and design RESTful integrations and Kafka message structures.
- Engineer Data Structures: Collaborate with developers to design PostgreSQL database schemas for microservices.
- Drive Data Engineering Requirements: Act as the primary technical partner for the Data Engineering team, defining requirements for ClickHouse tables and cloud storage logic to ensure the availability of relevant client, payment, and trading data for investigations.
- Executive Storytelling: Present technical designs and feature results to Company Owners and C-level stakeholders, distilling complex system logic into clear, persuasive, and professional narratives.
