 * A proactive problem solver who takes initiative and brings high ambition to a fast-moving team
 * Excellent analytical and problem-solving skills, with a focus on scalable solutions
 * Strong communication skills, including explaining complex technical concepts to non-technical stakeholders
 * Bachelor's degree in Computer Science, Engineering or a related field, or equivalent experience

## Description

* Own problems from scoping through shipping and iteration, working directly with business and engineering teams to turn ideas into production features across the full stack
 * Use agentic coding tools such as Claude Code, Codex and Cursor as a core part of how you design, build, test and review software - and help shape how the team gets the most from them
 * Work with our AI engineers to integrate AI features into the platform - wiring agents, LLM-powered workflows and MCP integrations into services and user interfaces, including streaming responses and sensible guardrails
 * Build and maintain microservices using Java 21 and Spring Boot, contributing to an open architecture that integrates the many players in the private markets ecosystem
 * Define, develop and optimise RESTful APIs, owning the contract between front end and back end with scalability and performance in mind
 * Work closely with designers to turn mockups into responsive, intuitive interfaces using React, TypeScript and Tailwind CSS, and contribute to the evolution of our design system and theming
 * Ensure seamless integration with third-party systems used by PE firms, distributors, private banks and fund administrators
 * Identify and fix bottlenecks across the stack - from data flow and service efficiency to front-end rendering and UX
 * Champion unit, integration and end-to-end testing, and DevOps best practices
 * Share knowledge and support other engineers, contributing to a culture of excellence and continuous learning
