Do you thrive on solving complex architectural challenges in distributed environments? Are you a strategic thinker who can balance high-performance edge constraints with seamless cloud synchronization? Then this is your chance to join a pioneering team building a next-generation platform. If you have deep expertise in both modern web technologies and systems programming and enjoy mentoring teams to adopt an offline-first mindset, you are the right person for us!!

Projekt Description:

Our project, GroundOS, is not just another screen manager. It is a next-generation Universal Display System (UDS) built to power the future of global mobility. We are building an "Operating System for Reality" that orchestrates massive, data-driven signage networks across critical infrastructure, from major international airports to sprawling public transport systems. GroundOS moves beyond static displays; it uses a state-of-the-art digital twin to process and react to real-time operational data. To guarantee continuous operation, the platform features a resilient, offline-first edge architecture that ensures screens keep running smoothly even if the network fails. Join us to blend high-performance Rust edge computing with modern TypeScript cloud services and help us set a new global standard for how hundreds of millions of passengers experience their journey.

 Tasks

• Design and model the overarching architecture bridging Cloud and Edge systems for complex domains (e.g., Airports).
• Evaluate and make strategic trade-offs between processing data locally for latency             (Rust) versus sending it to the cloud for aggregation (Node.js).
• Design embedded databases on edge devices and robust synchronization            mechanics to a central source.
• Translate complex architectural concepts (Eventual Consistency, Sync Conflicts)               into clear business implications for stakeholders.
• Bridge the technical gap between low-level Systems Engineers and high-level         Product Developers.
• Set the gold standard for code quality, architectural patterns, and documentation    across the stack.
• Mentor developers to transition from monolithic thinking to distributed/offline-first            mindsets.

 

Qualifications

• Extensive proven track record in designing distributed systems where "Cloud" and   "Edge" must sync.
• Deep understanding of Eventual Consistency, conflict resolution, and the      challenges of unreliable networks.
• Expert-level knowledge of TypeScript and NestJS for central cloud platforms.
• Strong proficiency in Rust for building high-performance edge computing agents.
• Comfortable managing memory and concurrency on resource-constrained               hardware.
• Experience in Event-Driven Architecture utilizing NATS for backend messaging.
• Experience implementing Type-Safe APIs, preferably using ConnectRPC.
• Excellent cross-domain communication and leadership skills.
• Expert knowledge of agile development
• Solid knowledge of Scrum
• Experience working in agile projects and teams
• Excellent English skills, both written and spoken (B2–C1)
• Excellent technical and analytical skills, as well as problem-solving abilities
• Ability to handle stressful situations and work independently

 

Advantages

• Experience with physical mobility or infrastructure domains (e.g., Aviation,               Logistics).
• Familiarity with IoT fleet management at scale
