Project description

We are seeking an experienced Software Developer to help modernize a mission-critical Portfolio Management System (PMS) used by investment professionals across front-office investment functions. The successful candidate will play a key role in transforming a mature WPF-based desktop platform into a modern, scalable, high-performance application ecosystem. The work includes UI modernization, platform upgrades, API development, performance optimization, architecture simplification, technical debt reduction, and AI-enabled user experiences. This role is well suited to an engineer with experience in buy-side portfolio, order, execution, risk, or investment analytics platforms who is comfortable working across desktop, web, service, integration, and data layers.

Responsibilities

• Key Responsibilities: Application Modernization
• Upgrade and modernize existing .NET, WPF, and DevExpress applications.
• Refactor legacy components, reduce technical debt, and improve maintainability.
• Improve the application user experience while preserving critical front-office workflows.
• Contribute to target architecture decisions and phased modernization plans. Performance Engineering
• Investigate and resolve application freezing, slow response times, memory leaks, and crashes.
• Profile and optimize desktop, server-side, database, and integration components.
• Improve data loading, caching, processing, and resource-management patterns.
• Implement appropriate diagnostics, logging, health monitoring, and performance measures. Architecture Simplification
• Reduce reliance on legacy SOA, middleware, and tightly coupled dependencies.
• Design simpler service-oriented and API-first components.
• Support migration toward modular, scalable, and supportable architecture patterns.
• Assess MongoDB dependencies and recommend pragmatic simplification or replacement approaches. API and Integration Development
• Design and build secure RESTful APIs for PMS data access.
• Develop integrations with trading, risk, reporting, analytics, and downstream systems.
• Implement authentication, authorization, validation, auditing, observability, and error handling.
• Produce clear API specifications and technical documentation. AI Enablement
• Build an AI-powered prompt/chat experience within the PMS.
• Integrate enterprise Large Language Models and approved AI services.
• Develop prompt orchestration, tool-calling, retrieval, guardrails, and workflow automation capabilities.
• Partner with investment users to identify and deliver high-value, controlled AI use cases. Web and Desktop Delivery
• Maintain and enhance rich desktop capabilities while introducing web-based applications where appropriate.
• Deliver across frontend, backend, service, integration, and data layers.
• Apply automated testing, code review, secure development, and CI/CD practices.
