Senior Software Engineer | Enterprise | Full-Stack

Meet the team behind this journey

DeepL is not just a translation tool; we are building the Operating System for Global Communication. We are the rare AI company that builds the entire stack in-house: from training next-gen LLMs on our own NVIDIA DGX SuperPODs to delivering real-time Language AI to over 300 million users and 200,000+ businesses globally.

You will join the Business Acceleration Track (BAT). This is 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.

Your responsibilities

• Architect Revenue-Critical Flows: You will design and ship complex, high-stakes features like "Enterprise Licensing" or "Automated Seat Provisioning." You ensure that when a customer upgrades, the UX is instant, and the billing ledger is immutable.

• Own the "Enterprise Experience": You will build the tools that empower CIOs and IT Directors to manage DeepL. You translate complex backend constraints (RBAC, Rate Limits) into simple, elegant UI workflows.

• Bridge the Gap: You are bilingual in "Engineering" and "Business." You work directly with Sales, Product, and Finance to translate "Annual Recurring Revenue" goals into scalable technical architectures .

• Drive System Reliability: You understand that billing systems cannot fail. You build for idempotency and resilience, ensuring that our financial data is auditable and flawless, while maintaining a high-velocity frontend experience.

Qualities we look for

• A "Product-First" Mindset: You care deeply about the customer journey. You ask, "How does this feature help us close the next Enterprise deal?" before writing code.

• Full-Stack Fluency: You are comfortable traversing the stack. You can design a React component for an Admin Dashboard in the morning and debug a distributed transaction in the backend in the afternoon.

• Enterprise Domain Curiosity: You are interested in the hard problems of B2B SaaS—Identity (SAML/SSO), Monetization, and Compliance. You understand that these aren't "boring details"; they are the pillars of trust for enterprise clients .

• High Agency: You don't wait for permission. If the billing reconciliation process is slow, you automate it. If the documentation for the API is unclear, you fix it.

• AI-Native Velocity: You leverage AI-powered tools (like GitHub Copilot or Claude) to accelerate your velocity and eliminate repetitive toil. You use AI for boilerplate code, test generation, and debugging, allowing you to focus your cognitive energy on high-value architectural decisions and complex problem-solving.

A Note on Our Hiring Process: DeepL hires for the Company, not just a specific team. We operate a Unified Engineering Pipeline. If you pass our bar, we will match you to the highest-priority role that fits your skillset—whether that is in Core Product, Platform, Voice, or Enterprise. We prioritize "Missionaries" who want to solve the biggest problems, wherever they live in the stack .

What we offer

• Diverse and internationally distributed team: joining our team means becoming part of a large, global community with people of more than 90 nationalities. We're more than just colleagues; we're a group of professionals with a shared mission to connect diverse cultures. Our global presence is growing–we've doubled in size nearly every year, with our employees based in the UK, Germany, the Netherlands, Poland, the US, and Japan, and we continue to expand our network.

• Virtual Shares - An ownership mindset in every role. We believe everyone should share in our success, and that’s why every employee receives Virtual Shares, linking your contribution directly to DeepL’s growth and rewarding you with a stake in our future.
