First seen by Alion on Oct 8, 2026.
Are you a skilled React developer experienced with fixed income trading? Join us to build new systems to support the bank’s fixed income business.

If you thrive on feedback, iteration, and creating applications that are a pleasure to use, this position is for you.
The Role at a Glance
Senior Frontend Engineer with React expertise
Requires understanding of fixed income trading flows
Fully remote for a top N. American bank (for residents of Poland or Romania)
Openings on multiple teams in the capital markets division
Part of the core team - this is not a legacy support role or an outsourced B team
We’re hiring experienced frontend engineers (6+ years) to join a major N. American bank, directly supporting the development of frontends for systems used to support the bank’s fixed income business. This is not a legacy maintenance or support role — you’ll be part of the core product team, building highly-performant trading system frontend UIs.
Join us and work on interesting financial system engineering problems.
Why Join Us?
Join an actively developed system. The engineers who built it originally are still on the team.
Collaborate with a world-class team of developers across North America and Europe.
Enjoy the stability of a long-term, fully remote role that only a bank can offer.
A successful candidate will be a very strong frontend programmer with current experience with TypeScript development. They must also be curious, open-minded, and desire to learn new things. English proficiency is a must.
The role requires knowledge of fixed income trading flows. Ideally, you will have worked on applications that dealt directly with RFQ flow, but other fixed income experience is welcome.
This role is for developers who are good at programming, and not merely applying learned techniques. We’re looking for people who understand how things work and are not merely practitioners or technicians. If you’re fascinated by understanding systems “under the hood”, this role is for you. Successful candidates enjoy geeking out on the internals and debugging application performance issues.
This is a fully remote front-end React development role for a developer in Poland or Romania. You will be working through a Polish company that will provide the support and administrative assistance to make you successful in the role. We are looking for people to join the team long-term.
To ensure efficient onboarding, you’ll work in sync with the American team during US Eastern business hours for the first two months. Working this way maximizes your time overlap for answering questions, which means you can learn quickly. That means working until 21:00 CET. After you demonstrate that you can work independently, you’ll have flexibility to shift closer to standard Polish business hours.
Only open to residents of Poland or Romania. Citizens and legal residents with permission to work in Poland or Romania are welcome.
Role & Responsibilities
Design, develop, and maintain desktop applications written in React in JavaScript and TypeScript using the OpenFin framework.
Ensure high performance and reliability by writing well-structured code.
Work with backend systems via REST APIs and data streaming. Ability to read backend Java code is a plus.
Participate in team discussions and contribute to architectural decisions for improving system scalability and maintainability.
What We’re Looking For
Must-Haves
6+ years of professional experience with React and JavaScript/TypeScript.
Understanding of fixed income trading. Ideally worked with the RFQ execution model, but other fixed income experience welcome.
Ability to follow and understand technical conversations, and clearly explain non-trivial systems.
Humility to ask questions where necessary.
Open mind, curiosity, and a strong desire to learn new technologies and business domains.
Ability to align your working schedule to US Eastern business hours during onboarding.
Nice-to-Haves
Exposure to backend Java (reading backend code occasionally helpful).
Experience developing with OpenFin, Electron, or similar desktop runtimes.
Financial market experience.
A computer science degree from a top Polish technical university.
