We offer a range of services across corporate and investment banking, capital markets, global transaction services, research & strategy and ESG Solutions. The Global FICC Technology group aims to drive business growth for our partners in the Front-Office, Operations and beyond. We do this with a mandate of delivering innovative new products, expanding our trading tool capabilities and modernizing critical platforms. About the Team Atomic Innovation (FICC Technology) is an exciting, innovative and growing team with the mission of transforming the app landscape across TD Securities. We do this by designing and developing next-gen platforms that produce a tangible impact to all business areas that depend on them. We're a specialized team of builders with a focus on delivering innovative full-stack solutions, but with a deep-rooted passion of crafting beautiful UIs. As part of the Atomic team, you will build and own a diverse range of products that power our business, spanning multiple business lines. This includes working with our industry-leading Desktop Interop platform or helping to scale our Metals, Energy or FX Trade Automation streams. We also strive to create a fun, but professional and inclusive work culture here in the Atomic team. In the last year, we have coordinated numerous team socials with activities like bowling, boat cruises, park hangouts and gaming at the local arcade . Senior Back-End Developer Atomic – App Innovation & Design Atomic is building the next generation of trade and workflow automation products for TD Securities’ Fixed Income, Foreign Exchange and Commodities businesses. We are looking for a Technical Product Designer who can turn complex, high-value workflows into simple, intuitive products used by front-office and operations teams. About Atomic Atomic Innovation is transforming the application landscape across TD Securities. We are a multidisciplinary team of product designers, engineers, and technology professionals building modern products for some of the bank’s most sophisticated business areas. Our portfolio spans Metals, Energy, Foreign Exchange, FX Options, Fixed Income, and Operations, along with the shared FICC Unified Desktop platform that brings these experiences together.

We value thoughtful product decisions, strong engineering, polished user experiences, and practical solutions that create meaningful value for our users. The Opportunity Atomic is looking for a Senior Back-End Developer to join the team building Atomic FX. Although the role carries a senior title, it is primarily a hands-on individual-contributor position focused on one product rather than technical leadership across the broader Atomic portfolio.

You will learn the workflows behind the product, contribute to technical discussions, build and support back-end services, and help improve the application as user needs evolve.
