SKILLS
ABOUT JONATHAN MULLER
I am an engineering leader driven by a long-term vision: building systems and teams that scale sustainably over time. I currently lead a full engineering organization of around 100 engineers, including developers, QA, SRE, and DevOps, with responsibility for both technical direction and organizational growth.My role is to align engineering execution with business strategy by defining clear architectural principles, delivery standards, and reliability goals. I focus on empowering autonomous teams through strong foundations, shared ownership, and a culture of continuous improvement. I believe that high-performing organizations are built on clarity, trust, and craftsmanship, not rigid process.Across mid- to large-scale platforms, I have contributed to raising engineering maturity by improving testing strategies, CI/CD pipelines, build systems, and automation. I have led architectural evolutions from tightly coupled or monolithic systems toward modular, decoupled, and independently deployable components, with a strong focus on maintainability and long-term adaptability.While I enjoy solving complex technical problems, the hardest challenges are often human. Change requires alignment and education. As a Scrum Master and leader, I facilitate transformation by supporting teams, mentoring technical leaders, and creating the conditions for sustainable change.My technical background spans software craftsmanship, distributed systems, and cloud-native architectures. I am comfortable working from low-level concurrency and performance optimization to large-scale platform design and automation.Key areas of expertise include:C++, Rust, Go, C#, Node.js, Python · Multithreading & concurrency · Distributed systems (CORBA, RMI, messaging) · Docker & Kubernetes · Linux, CI/CD, Ansible · Web platforms (Nginx, React) · Financial systems (FIX, pricing models) · Embedded systems (QNX)I am motivated by growing people and building durable systems that remain resilient, evolvable, and inspiring as organizations scale.
