Senior .NET/C# Software Engineer, Alkmaar

Join Our Team as a Senior Software Engineer (.NET/C#) at Beyond Sports If you are an experienced engineer who thrives on algorithmic complexity, loves applying

Domain Driven Design

to solve real-world problems, and wants to build the logic that drives the next generation of sports visualisation, we want to talk to you.

What Your Day Will Look Like As a Senior Software Engineer, you will own the critical logic that transforms raw, noisy signals into clear sports narratives. You will architect the complex systems responsible for

detecting timing and actions , distinguishing a pass from a shot, or identifying a foul in real-time. You will lead the development of robust

error detection systems

for positional tracking data, ensuring our pipelines are resilient enough to handle live broadcast pressure. You will be responsible for defining the

data structures

used to exchange information between the Core Data team,

Game Developers, and Data Scientists , ensuring seamless integration across the company. You will also be a mentor. You’ll guide the team in

Domain Driven Design , conduct code reviews that focus on algorithmic efficiency, and ensure our libraries for enhancing tracking data are scalable, maintainable, and well-documented.

What We Value At Beyond Sports, we value raw engineering talent. We are looking for someone who understands the "why" behind the code and can translate abstract business concepts into technical reality.

You’ll fit right in if you: Excel at "Problem Solving" Engineering.

You love math, algorithms, and solving distinct logical puzzles.

Are a DDD Expert.

You know how to use Domain Driven Design to map the complex rules of sports into clean, maintainable software.

Build for Scale.

You design systems that can handle large streams of data on cloud platforms (AWS preferred).

Lead by Example.

You communicate complex technical ideas clearly to project managers and teammates, and you elevate the code quality of everyone around you.

This role is based on-site at our

Alkmaar office

(40 hours per week). You’ll need to be living in the Netherlands and eligible to work in the EU.

Tech Stack and Skill Requirements You don’t need to tick every box, but here’s what we’re looking for: BSc or MSc in Software Engineering

(or equivalent formal qualification).

Expert-level proficiency in C# and .NET.

Proven experience with Domain Driven Design (DDD).

Deep Algorithmic Knowledge:

Experience developing event detection or error correction systems.

Cross-functional collaboration:

Experience designing data structures for use by other teams (e.g., Data Science/Game Dev).
