About KWAN

At KWAN, we connect tech talent with projects that match their skills, interests, and goals. We also offer a career development program guided by our People Experience Partners, who support your growth and work-life balance from day one.

We’re currently hiring for a senior-level role in software development, focused on building robust, high-performance applications using C++ and Qt/QML, in a technical environment that values precision, performance, and ownership.

What is the challenge about:

You’ll be working on the end-to-end development of embedded or embedded-like applications, from early-stage design to deployment and optimization. You’ll join a team that values clean architecture, modern standards, and technical autonomy — and you'll have real influence on the product's performance and direction.

What we are looking for:

- Academic background in Engineering or a related field (e.g., Software, Electronics, Physics, Mathematics);

- At least 5 years of professional experience in software development;

- Strong proficiency in C++ and deep understanding of modern C++ standards (C++11 and beyond);

- Solid experience with Qt/QML, particularly in the context of embedded application development;

- Experience across the entire software development lifecycle: requirements, design, coding, testing, documentation, deployment, integration, and training;

- Knowledge of C and Rust is highly valued;

- Experience with embedded systems is a strong plus;

- Familiarity with performance analysis and memory profiling tools;

- Ability to take full ownership of complex systems — from architecture and prototyping to performance tuning;

- Strong skills in defining and communicating technical vision, capable of guiding both peers and stakeholders;

- A proactive, curious mindset, and a passion for learning and sharing knowledge;

- Good command of spoken and written English.
