Join Elfsquad's Development Team
We’re in the process of transforming Elfsquad into the world’s smartest CPQ platform. One that lets users build, visualize, and sell custom products directly online, with or without engineers involved.
Under the hood, our logic engine is evolving, and now, AI is part of that transformation. As a Senior Back-end Developer, you won’t just be writing performant APIs. You’ll help architect the core logic that powers configuration intelligence and supports AI-driven automation.
Think smart rule resolution, guided selling, dynamic pricing, and optimization at scale. This isn’t a typical back-end job. It’s about logic, AI, and architecture coming together to shape how global manufacturers operate digitally.
If you're a senior back-end dev who wants more than another REST API, welcome home. You’ll architect the core of a highly modular CPQ platform that adapts to global use cases. You’ll also work alongside a fast-moving product squad that learns quickly and avoids unnecessary meetings. This isn’t just about writing performant code — it’s about solving puzzles that most devs will never encounter.
What You'll Be Doing :
- Design and build scalable, modular logic engines that drive dynamic configuration workflows
- Implement and maintain complex rule systems — dependencies, constraints, pricing models
- Integrate machine learning outputs directly into configuration, pricing, and optimization processes
- Develop performant APIs that handle deeply nested models, used by internal teams and external partners
- Explore use cases like AI-powered suggestion engines, auto-complete logic trees, and dynamic feature resolution
