Backed by top-tier investors and trusted by global OEMs, we’re shaping the next generation of industrial intelligence.

Your Role

As a Senior Software Architect, you’ll play a pivotal role in executing the technical vision behind our SaaS-based IoT platform. This is a hands-on leadership role that blends architectural oversight with direct contributions to key systems. You’ll work closely with cross-functional teams and company leadership to ensure our architecture remains robust, secure, and aligned with a clear technical roadmap.

You won’t just guide from the sidelines — you’ll actively design, prototype, and build core backend components, ensuring our architecture not only looks great on paper but performs at scale in production.

What You’ll Do

• Drive the implementation and evolution of our cloud-native, multi-tenant SaaS architecture, following a defined technical strategy.
• Collaborate directly with leadership to keep architectural decisions aligned with product milestones and business goals.
• Take a hands-on role in developing key backend services and infrastructure, primarily in Python (FastAPI), with optional use of Rust (Rocket, Axum).
• Provide architectural guidance while actively contributing to backend development.
• Champion system reliability, observability, and modern infrastructure-as-code standards across AWS and Azure environments.
• Embed security and data integrity principles deeply into every architectural decision — industrial data security is non-negotiable.
• Work closely with DevOps and product teams to implement robust infrastructure and integration across cloud and edge.

What You Bring

• 5+ years in software architecture with proven hands-on contributions to production-grade systems.
• Deep expertise in backend development with Python and FastAPI, plus experience or interest in Rust (Rocket, Axum).
• Solid track record designing scalable microservices, modern CI / CD, and container orchestration (Docker, Kubernetes).
• Practical experience with AWS and / or Azure, deploying resilient cloud infrastructure.
• Strong understanding of data pipelines, real-time stream processing, and distributed systems.
• Bonus : Knowledge of edge computing, IoT protocols (MQTT, AMQP) or industrial automation contexts.
• Confident communicator who collaborates across teams and reports clearly to senior stakeholders.
• A builder’s mindset : you thrive on delivering robust, maintainable components hands-on.

Why Join Tomorrow Things?

• Be a key executor of an architecture powering the future of industrial AI and automation.
• Combine high-level system design with real, production-grade development.
• Join a mission-driven team solving practical, high-impact challenges at the intersection of industry and innovation.
• Competitive salary, meaningful equity, and genuine ownership.
• Remote-first culture with flexible working options and a collaborative team based in Bonn.
