- Experience or hands-on exposure to Shopify app development or e-commerce integrations
- Familiarity with Shopify APIs, especially the Shopify Admin and Storefront GraphQL APIs
- Experience integrating front-end applications with REST and/or Shopify-specific GraphQL APIs
- Comfortable collaborating with backend engineers and working with existing backend services

What the job involves
- We are looking for a mid-level Shopify Developer with a strong front-end engineering focus to help build and maintain integrations between Shopify and the Talon.One promotion engine
- In this role, you will primarily work on Talon.One front-end application and embedded Shopify apps that are used by Shopify merchants to configure, manage, and monitor how Talon.One promotions are applied in their stores. You will collaborate closely with backend engineers, product managers, and solution teams to deliver reliable, intuitive, and high-quality integration experiences
- For this position, we need professionals who are already based in Berlin or are willing to move to Berlin
- Build and maintain front-end applications using React and TypeScript for Shopify merchants
- Develop and improve embedded Shopify apps, including setup flows, configuration UIs, and diagnostics
- Integrate front-end applications with Shopify APIs (Admin API, Storefront API, Webhooks), primarily using Shopify’s GraphQL APIs

Our take
Talon.one initiates and automates loyalty programs and discount campaigns for product-oriented businesses. Its varied product service includes coupon, referral, gift card, and loyalty software as well as product bundles and wallet solutions.
Paradoxical to its mission to create developer-free promotion tools for companies, Talon.one was actually founded by several software developers. In 2022, the company partnered with Big Commerce to offer promotion engine features to Jimmy Brings, an Australian alcohol delivery company, highlighting its integration capabilities as it had to collaborate effectively with various software companies.
Talon.one's offering has a lot of potential, which hasn't gone unnoticed, and its secured a hard-hitting client list that includes Mercedes, Delivery Hero and Adidas. It also raised some serious growth funding in 2025 which puts it in a great position as it eyes thoughtful and sustainable long-term growth.
