Senior Software Engineer | Enterprise | Full-Stack

DeepL is a global AI product and research company focused on building secure, intelligent solutions to complex business problems. Over 200,000 business customers and millions of individuals across 228 global markets today trust DeepL's Language AI platform for human-like translation, improved writing and real-time voice translation. Founded in 2017 by CEO Jaroslaw “Jarek” Kutylowski, DeepL now has around 1,000 passionate employees and is supported by world-renowned investors including Benchmark, IVP, and Index Ventures. You will join the Business Acceleration Track (BAT), the engine room of DeepL’s global growth. While our Research teams build the models, BAT builds the Revenue Flywheel that allows 200,000+ Enterprises (like the Fortune 500) to actually use and pay for them at scale. We are moving upmarket. We are transitioning from a consumer-focused app to a mission-critical Enterprise Platform. You will be part of the team architecting the “Financial Nervous System” of DeepL — handling everything from Identity & Access Management (SSO, SCIM) to complex multi-seat Subscription Architectures and Fraud Prevention. We don't hire engineers to just implement UI tickets. We hire Missionaries who understand that a perfect AI model is useless if a Global Enterprise can't provision it securely to 50,000 employees. You will own the full vertical: from the user-facing Admin Console in React to the distributed billing logic in C#/.NET.
