Senior Back-End Developer

Are you a senior back-end developer looking to tackle complex logic and shape a transformative platform? Then you might be exactly who we’re looking for.

We’re mid-flight on 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 in the loop.

About the Role

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

Your Stack:

  • C# (.NET Core) – The backbone of our platform.
  • Azure SQL / Redis — data management and high-speed access
  • Event-driven architecture — for a clean, modular system
  • AI/ML models (integrated via APIs) — for predictive logic, guided configuration, and more

Why Elfsquad:

  • We’re solving real-world complexity with technology that matters
  • You’ll work closely with AI engineers, front-end teams, and product owners, no silos here
  • We move fast, build with purpose, and love big ideas
  • The stuff you’ll build is used by manufacturers across the world, at scale

You:

  • Strong in C# or a comparable high-performance compiled language.
  • Have several years of experience (+ 3 years) developing high-quality software
  • Comfortable translating complex business logic into clean, maintainable code.
  • Skilled in building APIs that are fast, stable, and loved by front-end devs.
  • A believer in clean architecture, modularity, and event-driven systems.
  • Passionate about working closely with product, AI, and design teams
  • Are fluent in Dutch and English, verbally and in writing

Bonus points if you:

  • Experience integrating AI models (e.g., OpenAI, Azure AI, or in-house ML models) into real products
  • Dealt with logic complexity far beyond REST endpoints — and loved it
  • Designed platforms that scale with customer-level customization
  • Love teaching and mentoring other developers.

We offer:

  • Competitive compensation & flexibility: attractive salary and benefits, with the option to work from home and remote from abroad
  • Growth & development: career acceleration opportunities, supported by tools, training, and coaching
  • Impact & ownership: take on real responsibility, directly contributing to the digital transformation of manufacturing
  • Vibrant & international team: informal, collaborative environment where achievements are celebrated
  • Modern workplace & tools: a well-equipped office designed to support creativity and productivity
