About EGIDE

EGIDE is building a new European defense leader focused on scalable, intelligent, air-defense architectures. We develop mass-use interceptors and mission systems that combine missile-grade performance with modern embedded computing and advanced autonomy.

We are growing fast and assembling a world-class technical team driven by ambition, engineering rigor, and real operational impact. If you want to help shape the future of European defense innovation, this is the place.

About the Role

We are seeking a highly skilled Software Engineer (Python/C++) to design and develop core components of a state-of-the-art flight simulator (for drone like UAVs). This role focuses on building high-performance, physics-accurate simulation systems from the ground up, including low-level C++ engines and Python bindings for usability and extensibility.

You will be involved across the full software lifecycle, from system architecture and core engine design to testing, benchmarking, and deployment, working closely with the system engineering team.

What You’ll Do

1. Software Architecture & Core Development

• Design and implement robust, scalable software architectures for simulation systems

• Develop high-performance components in C++

• Create and maintain Python bindings for core simulation modules

• Ensure clean interfaces between low-level and high-level components

2. Performance & Reliability

• Implement unit tests and integration tests to ensure correctness

• Design and execute benchmarks to validate system performance

• Maintain high code quality through best practices and code reviews

3. CI/CD & Development Practices

• Set up and maintain CI/CD pipelines for automated testing and deployment

• Manage version control workflows using Git

• Enforce modern software engineering practices (testing, documentation, reproducibility)

• Improve developer tooling and workflows

1. Simulation & Physics Integration

• Collaborate with domain experts to implement accurate physical models

• Translate mathematical and physical models into efficient numerical code

• Ensure fidelity and stability of simulation algorithms

You are a Fit If You Have:

• Strong experience in C++ and Python development

• Solid understanding of software architecture and design patterns

• Experience building Python bindings

• Proficiency with Git and collaborative development workflows

• Experience with CI/CD systems and automated testing frameworks

• Good foundation in mathematics and theoretical physics

• Ability to promote and enforce good engineering practices across a team (code quality, testing, tooling, workflows)

Nice to Have:

• Experience with simulation systems, game engines, or physics engines

• Knowledge of numerical methods and scientific computing

• Experience in early-stage or R&D-driven projects

• Familiarity with benchmarking and profiling tools

• Experience with Linux system administration (e.g., managing self-hosted GitLab CI/CD infrastructure)

• Proactive mindset in improving team-wide engineering practices, tools, and workflows

Why Join EGIDE?

• Build the future of European defense capability

• Work on real systems that fly fast

• Competitive salary + meaningful equity

• 100% health coverage

• A high-autonomy engineering culture

• A chance to shape a category-defining company from the ground up
