Role Overview
We are seeking a Senior Trading System Front End GUI Developer to lead the design and development of mission critical trading interfaces used by portfolio managers, traders and execution support teams at Polymer.
You will own and evolve real time, latency sensitive trading applications where correctness, speed, and clarity directly affect trading outcomes and P&L. You will act as a technical authority for user facing execution systems, shaping the UI architecture, defining standards, and mentoring others while remaining deeply hands on.
Core Responsibilities
Ownership of Trading GUIs
- Own the end-to-end lifecycle of trader-facing applications
- Order entry and execution management
- Real‑time blotters (orders, trades, positions, P&L)
- Market data and analytics visualization
- Act as the primary technical decision‑maker for front‑end architecture and UI patterns
- Incorporate disparate requirements from a diverse group of portfolio managers and traders into a coherent design
- Employ modern application packaging and distribution for easy user-initiated installation
Real-Time & Latency-Sensitive Systems
- Build GUIs that handle high volume of updates scaling up to a few million events and handle market‑open and event‑driven stress scenarios
- Ensure deterministic UI behavior under load (no freezes, no stale states, no incorrect displays)
- Optimize rendering, threading models, and event pipelines for performance
Trader & PM Enablement
- Partner directly with traders and PMs to:
- Design workflows that minimize reaction time
- Optimize keyboard‑driven and automation‑friendly interaction
Risk & Control Integration
- Implement pre‑trade and post‑trade risk visibility directly in trading screens
- Ensure UI behavior aligns with internal controls and compliance expectations
Architecture & Platform Leadership

- Real‑time messaging contracts
- Error handling and fail‑safe behavior
- Collaborate with backend teams on:

- Contribute to long‑term platform evolution, not just feature delivery
Required Experience & Skills

- Deep understanding of:
- Order lifecycles (new, amend, cancel, fill, reject)
- Trading workflows across PM → trader → execution

- Strong grasp of:
- Event‑driven architectures
- Concurrency and threading models
- Performance profiling and optimization
- Application communication protocols like HTTP, Soup, REST and FIX
Expectations
- 8+ years professional software engineering experience
- Demonstrated ability to:
- Design systems, not just screens
- Make pragmatic architectural trade‑offs
- Review and elevate the quality of others’ code
- Comfortable operating with high autonomy and minimal process
