This position is ideal for experienced system-level C++ engineers to join our team in building a cutting-edge distributed microservices-based 3D CAD platform.

As a Sr. Software Engineer, you will work on performance-critical components, advanced geometry processing, and scalable cloud-native architecture. Collaborating with domain experts, architects, and platform engineers, you'll help shape a next-generation CAD system from the ground up. This role is key in bridging low-level geometric computation with high-level service design.

Role expectations

  • Design and implement core components of a distributed 3D CAD system in modern C++ (C++17/20).
  • Develop algorithms using linear algebra and 3D geometry.
  • Collaborate on microservice design, API definition, and cloud orchestration.
  • Optimize performance for compute- and memory-intensive workloads.
  • Contribute to system reliability, monitoring, and CI/CD automation.
  • Participate in code reviews, design sessions, and cross-team technical discussions.
  • Document mathematical models and architectural components clearly.

What we're looking for

  • Education: Bachelor’s or Master’s degree in Computer Science, Applied Mathematics, or related field.
  • Experience: 8+ years in modern C++ development in performance-critical or real-time systems.
  • Skills:
    • Solid foundation in mathematics, especially linear algebra and geometry
    • Strong proficiency in C++ (17 or newer) and STL
    • Understanding of microservices architecture and inter-process communication (gRPC, REST)
    • Experience with concurrent programming and performance profiling
    • Familiarity with distributed systems, containers (Docker), and orchestration
  • Communication: Ability to explain complex mathematical and architectural ideas clearly.
  • Teamwork: Collaborate closely in agile teams with platform, DevOps, and product counterparts.

Complementary skills

  • Experience with 3D modeling engines, CAD kernels, or graphics APIs
  • Knowledge of Go is a strong plus (some backend services use Go)
  • Familiarity with CI/CD, monitoring tools
  • Exposure to cloud-native ecosystems (e.g., AWS)
