About this Staff Systems Architect (f/m/d) role at STRATO EN

STRATO EN · Onsite · Otto-Ostrowski-Straße 7, 10249 Berlin

With over 4 million domains and more than 2 million customers, we, as an IONOS company, are among the largest web hosting providers worldwide. We operate two TÜV-certified data centers with over 70,000 servers. Our products are diverse and form the backbone of our success, but they only come to life through our amazing employees.

You are the primary guardian of the technical boundary between the Nextcloud Office frontend and the LibreOffice C++ core. Your job is to solve the "impossible" architectural hurdles that arise when syncing a massive, stateful C++ engine with a modern, real-time Node.js environment. 

Tasks

  • The Blueprint: Design the communication protocols (Websockets, WOPI, Shared Memory) that allow Node.js to command the C++ core with sub-10ms latency.
  • Digital Archaeology: Reverse-engineer legacy C++ components to find the "Source of Truth" for complex document states and map them to our modern JS architecture.
  • AI Orchestration: Curate the technical context (RAG) for our AI sub-agents. You ensure the LLMs "understand" the unique quirks of the LOKit core so the rest of the team can code with precision.
  • High-Stakes Review: Act as the final gatekeeper for all bridge-related code. You don't just check if it works; you check if it's mathematically sound for real-time collaboration.

Qualifications

  • Expert-level C++ (Modern standards + Legacy understanding).
  • You likely have experience in Game Engine Architecture.
  • Experience with High-Frequency Trading—environments where the "cost of abstraction" is measured in milliseconds.
  • Hands-on experience with AI development tools and AI orchestration, including managing RAG-based technical context to improve code generation accuracy and support engineering workflows.

Benefits

  • Hybrid working model.
  • Flexible working hours through trust-based working hours.
  • At some locations a subsidized canteen and various free drinks.
  • Modern office space with very good transport connections.
  • Various employee discounts for activities and products.
  • Employee events such as summer and winter parties, as well as workshops.
  • Numerous training and development opportunities.
  • Various health offers, such as sports and health courses.

We value diversity and welcome all applications - regardless of, for example, gender, nationality, ethnic or social origin, religion, disability, age as well as sexual orientation and identity, physical characteristics, marital status or any other irrelevant factor subject to applicable law.

STRATO goes green: Since 2008, we have been operating our data centers with eco-friendly electricity.

 

Start-up flair - even though we haven't been one for a long time: Bored in your current job? No opportunities for development and not quite the right fit? Come to STRATO! We have much more to offer than can be expressed here.
