Remote Senior Backend Engineer (Django/FastAPI) (m/f/d)

We’re hiring a Senior Backend Engineer to join our RM dev team at RoomPriceGenie! In this high-impact role, you’ll architect, build, and optimize the backend systems that power our product experience — from APIs and business logic to optimization algorithms, data flows, and performance-critical services. You’ll take ownership of complex technical challenges, shape our backend architecture, and ensure our platform remains robust, scalable, and secure as we grow. As a senior individual contributor, you’ll stay deeply hands-on with Django, FastAPI, PostgreSQL, and modern backend practices. You’ll collaborate closely with frontend, data, and product teams, drive technical excellence, and foster a culture of clean code, strong testing, and continuous improvement. If you love crafting elegant backend systems, solving challenging problems at scale, and delivering real impact, we’d love to hear from you! ✨ ️ High ownership. Real impact. Great people.

Activities

In this role, you’ll be taking a key role in helping us build the systems that turn first-time users into lifelong RoomPriceGenie champions. Your primary focus will be backend development in Python/Django, where you’ll design and deliver resilient services and APIs that make our activation and growth engine smarter every single day.

You’ll take full ownership of projects—from exploring the problem space and shaping technical solutions, all the way to implementation, deployment, monitoring, and iteration based on real user outcomes. You’ll write clean, maintainable, and well-tested code, applying modern testing practices across unit, integration, and functional layers to ensure we deliver quality at speed.

Collaboration is baked into this role: you’ll partner with Product, Data, Design, and engineers from different domains to ship end-to-end features that improve onboarding, increase engagement, and enhance long-term customer success. While your home base is the backend, you’ll sometimes dip into data workflows (Snowflake, Airflow, dbt) and contribute to the development GenAI applications to keep the momentum high and help the team move quickly.

You’ll also play a crucial role in maintaining the health of our systems. You’ll participate in architecture reviews, bring your perspective to technical discussions, and mentor fellow engineers—raising the bar for engineering excellence across the team.

Beyond feature development, you’ll help evolve how we work: improving our CI/CD pipelines, refining deployment processes, strengthening monitoring and alerting, and adopting tools and practices that enable a fast, reliable, and delightful developer experience. As a product-minded engineer with high ownership, you’ll make thoughtful trade-offs, always keeping user value and measurable impact at the center of your decisions.

This is a role where your ideas matter, your code reaches thousands of users, and your work has a direct, visible impact on the success of small hotels around the world. You’ll operate with autonomy, collaborate with a talented and diverse team, and help shape the future of a fast-growing, mission-driven startup.
