Senior Software Engineer | Enterprise | Full-Stack

• 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.

Do you have experience in C#?, * 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.
