Lead Software Engineer

About Spacebackend 

Spacebackend revolutionizes system integration in the aerospace industry through AI-driven interoperability across various hardware components. Our product Lynapse streamlines the entire satellite integration workflow by enabling modular integration across payloads, components, and subsystems. The Lynapse core technology transforms hardware specifications into digital twins and automatically generates, tests, and validates hardware-agnostic, OS-agnostic on-board satellite middleware software. Lynapse is a web-based collaborative modeling and design tool for mission-critical projects, allowing teams to create, test, validate, and simulate data interfaces for dozens or hundreds of hardware components composing satellites, spacecraft, or lunar landers. 

Role Overview 

As Lead Software Engineer, you will architect end-to-end solutions and guide a multidisciplinary team, including AI researchers, embedded software engineers, and full-stack developers to deliver our integrated platform. You’ll spend 80% of your time hands-on coding in C/C++/Python/C# and 20% managing, mentoring, roadmap planning, and coordinating R&D across product phases. 

What You’ll Do 

System Architecture & Roadmap

• Define and evolve software architecture spanning on-board middleware, AI integration layers, frontend, backend and cloud services. 
• Lead the product roadmap: prioritize features, set milestones, and align technical plans with business objectives. 
• Write technical documentation including product requirements, solution architecture and design review documents. 

Hands-On Development 

• Implement core modules in C/C++, Python, and C# for backend services, ensuring high performance, reliability, and maintainability. 
• Design and architect interfaces between AI/ML models and application infrastructure (APIs, messaging, data pipelines). 
• Architect and develop SDK/API for integration of core technology into 3rd party products and workflows. 

Team Leadership & Coordination 

• Mentor and manage multidisciplinary teams to foster collaboration, code quality, and iterative delivery. 
• Coordinate R&D activities: organize sprints, review experiments, and integrate research outputs into production code. 

Infrastructure & Best Practices 

• Establish DevOps pipelines (CI/CD, automated testing, container orchestration) across cloud and on-prem environments. 
• Promote design patterns, coding standards, and architecture reviews to ensure scalable, modular solutions.

2. 5+ years of professional software development with 2+ years in software architecture or technical leadership 
3. Proficiency in C and C++ (embedded contexts is benefit) and C# or Java (backend services) 
4. Experience designing distributed systems, modular middleware, and API-first architecture 
5. Proven track record managing or mentoring teams in agile, iterative environments 
6. Familiarity with DevOps tools: Docker, Kubernetes, CI/CD pipelines, and cloud platforms (AWS, Azure, GCP)

Preferred (Nice-to-Have)

1. Background in integrating AI/ML models into production workflows 
2. Experience with digital-twin frameworks or simulation tools
3. Hands-on embedded firmware development or hardware-in-the-loop testing
4. Experience with space systems

What We Offer 

1. Salary + equity package 
2. Flexible hours & on-site work at Technoport Belval, Luxembourg 
3. Career path to technical executive roles 
4. Opportunity to shape the future of aerospace integration technologies
