At TechBiz Global, we are providing recruitment service to our TOP clients from our portfolio. We are currently seeking a Senior EmbeddedSoftware Engineer to join one of our clients' teams. If you're looking for an exciting opportunity to grow in a innovative environment, this could be the perfect fit for you. ABOUT THE CLIENT Our client is an innovative aerospace technology company that is transforming system integration through AI-driven interoperability. Their core platform streamlines satellite integration workflows by enabling modular connectivity between payloads, components, and subsystems. It converts hardware specifications into digital twins and automatically generates, tests, and validates on-board middleware software that is both hardware- and OS-agnostic. This web-based collaborative tool supports mission-critical projects, allowing teams to efficiently model, test, and simulate data interfaces for satellites, spacecraft, and lunar landers. NOTE: this position requires working on-site and relocation to Luxembourg. JOB DESCRIPTION: As Lead Software Engineer, you will architect end-to-end solutions and guide a multidisciplinary team, including AI researchers, embedded software engineers, and fullstack 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 1. 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. 2. 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. 3. 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. 4. 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. Bachelor’s or Master’s in Computer Science, Electrical Engineering, Software Engineering, or related field 5 years of professional software development with 2 years in software architecture or technical leadership Proficiency in C and C++ (embedded contexts is benefit) and C# or Java (backend services) Experience designing distributed systems, modular middleware, and API-first architecture Proven track record managing or mentoring teams in agile, iterative environments Familiarity with DevOps tools: Docker, Kubernetes, CI/CD pipelines, and cloud platforms (AWS, Azure, GCP) Nice-to-Have Background in integrating AI/ML models into production workflows Experience with digital-twin frameworks or simulation tools Hands-on embedded firmware development or hardware-in-the-loop testing Experience with space systems
