The Team: We are looking for an amazing developer to join our team building FlexTrade's OEMS platform, FlexONE, which is our state-of-the-art, fully integrated Order Management System and Execution Management System. This system was built from the ground up starting in 2013 and is written entirely in Scala. The FlexONE team is split between our Milwaukee office, where the product was first, and our London office, which is now predominantly responsible for development of the UI for the application. The London team is an experienced group of Java and Scala developers, with a deep understanding of UI and UX design. We deliver our software using agile methodologies, and we encourage best practices such as TDD, code reviews and pair programming for knowledge sharing and learning. Our team owns all aspects of the features they work on, from designing solutions to meet customer or product requirements, through implementation, QA and delivery. Each team member works on every part of the system.
About You: As Senior Web Developer, be part of our FlexONE team and own critical product surfaces across our web and mobile applications. You'll work end-to-end across a Scala + Play Framework backend, and a React + AG-Grid front-end, using gRPC for communication with our core product's backend systems. You will lead the technical direction as we build our Web app from an MVP to a comprehensive companion to the desktop application, as well as continuing the evolution of our Mobile app.
Responsibilities:
- Design & Build: Deliver robust, maintainable features across the stack (Scala/Play backend, React/AG-Grid frontend)
- Mobile Migration: Define the path from Codename One to a JS-compatible framework (likely React Native), including architecture, incremental migration strategy, and performance/UX parity
- Quality & Reliability: Champion code quality, testing, observability (metrics, logs, tracing), and performance across the stack
- Team Growth: Mentor engineers, assist with hiring, onboarding, and capability development as the team scales.
- Collaboration: Partner closely with the Desktop application development team to ensure feature compatibility and parity
Tech Stack:
- Backend: Scala, Play Framework, REST/JSON and gRPC
- Frontend: React, TypeScript, AG-Grid
- Mobile: Current app in CodenameOne, target migration to React Native (or similar JS-based cross-platform framework)
- Tooling: Jenkins, GitLab, SonarQube, IntelliJ IDEA
Deep Full Stack expertise. Experience building & deploying production web apps, with significant experience in React and modern TypeScript. Strong experience in Scala (or any JVM language including core Java). Mobile Capability: Experience building or maintaining cross-platform Mobile Apps. Architecture & Design: Solid grasp of API design, web & mobile architecture, as well as good UX design. Communication: Clear, pragmatic communicator who collaborates well with both engineers and non-engineers.
