Senior System Architect | Distributed Systems & Event-Driven Excellence

Rimthan is a Riyadh-based corporate venture builder driving Saudi Arabia’s digital transformation in line with Vision 2030. We launch and scale innovative digital ventures across the Middle East.

Our Polish delivery hub is a key part of this journey - a dedicated engineering powerhouse combining European technical excellence with startup agility and enterprise-grade standards. Together, we build impactful products that reach real users, fast.

About the Role: As a Senior System Architect, you aren’t just drawing diagrams; you are the master weaver of our digital infrastructure. You will own the blueprint for scalable, resilient, distributed event-driven systems that power our next generation of ventures.We are looking for a visionary who bridges the gap between complex business logic and elegant technical execution. If you believe that architecture should be as fluid as it is robust, and you have a passion for "Class C" level reliability, you’ll fit right in.

What You’ll Do

• Architect for Scale: Design and implement high-performance, distributed event-driven systems that thrive under pressure.

• Tech Leadership: Act as the North Star for our engineering teams, providing mentorship and setting the gold standard for clean, maintainable architecture.

• Multi-Cloud Mastery: Navigate and optimize across GCP, AWS, Azure, and Oracle, ensuring our systems are cloud-agnostic where it matters and optimized where it counts.

• Bridge the Gap: Collaborate closely with stakeholders to translate ambitious business goals into concrete, scalable technical roadmaps.

• Optimize & Evolve: Don't just build it and forget it. You’ll constantly audit existing systems for cost-efficiency, security, and performance bottlenecks.

• Document the Vision: Create clear, actionable architectural documentation that empowers developers to build with confidence.

  
  

You Might Be a Good Fit If You...

• Are a Proven Architect: You have a track record of shipping production-grade distributed systems and living to tell the tale.

• Speak "Event-Driven": You have deep expertise in message brokers, streaming platforms, and eventual consistency.

• Are Cloud-Fluent: You are comfortable working across GCP, AWS, Azure, and Oracle. (Bonus points for experience with Class C infrastructure).

• Value Craftsmanship: You take extreme ownership of your work. Security, reliability, and performance aren't "features"—they are your baseline.

• Are Node.js-Aware: While you’re a language agnostic at heart, familiarity with Node.js helps you speak the same language as our core delivery teams.

• Communicate with Clarity: You can explain complex architectural trade-offs to a CEO just as easily as you can debate them with a Lead Engineer.
