Role description

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.

  • 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
