• Deliver high‑quality, secure and scalable code for platform features supporting window management, IPC, process lifecycle and runtime services.
• Own technical implementation from design through production rollout, including documentation, testing, instrumentation and operational readiness.
• Ensure platform components meet the firm's performance, resiliency and security standards.

.NET Electron Convergence

• Lead the engineering effort to unify components with new Electron‑based modules under a consistent desktop architecture.
• Build and maintain interop layers between native Windows code and Electron runtimes (IPC preload scripts, custom Electron APIs, native add‑ons).
• Make informed technical decisions on wrapping, migrating or retiring legacy native components.
• Define coding standards and patterns for hybrid native/Electron desktop development across the firm.

Container‑Based Layout Management

• Architect and implement a containerized window and layout management framework to orchestrate multi‑application, multi‑window workflows.
• Build core features including docking, snapping, grouping, tiling, tabbing and workspace persistence.
• Ensure the layout system integrates seamlessly with native Windows windowing and Electron UIs.
• Provide APIs enabling internal development teams to programmatically place groups and manage windows within containers.

Leadership & Collaboration

• Provide hands‑on technical leadership and mentorship to engineers across platform and application teams.
• Partner with architects, infrastructure, UX and business engineering teams to align platform strategy with firm‑wide standards.
• Produce clear technical proposals and influence platform roadmaps through data‑driven recommendations.
• Represent the Desktop Engineering team in architecture reviews, design sessions and cross‑Lines‑of‑Business initiatives.

Required Skills & Experience

• 8 years of professional experience developing Windows desktop applications in C#.
• Deep understanding of Win
  32 APIs, Windows messaging, window lifecycle, IPC, COM and OS internals.
• Strong hands‑on experience building or integrating with Electron JavaScript/Type Script.
• Experience with native modules (N‑API, C/CLI/C# Interop) and bridging native code with Electron runtimes.
• Proven ability to architect modular, scalable desktop systems in large enterprise environments.
• Strong communication skills with the ability to influence technical decisions and lead engineering efforts.
• Track record of delivering high‑quality production code in complex distributed environments.

Nice‑to‑Have

• Experience with Open Fin runtime adapters and integrating native components into Open Fin‑based containers.
• Experience building docking/tabbing or advanced layout frameworks.
• Experience with secure desktop runtimes, code signing, enterprise packaging and regulated environments.
• Prior experience in financial services or large‑scale enterprise platforms.

Impact

As a Lead Engineer at JPMorgan Chase you will:

• Shape the future of the firm's desktop platform.
• Deliver critical components used by thousands of users globally.
• Modernize legacy desktop assets into a unified, extensible platform.
