Job description

We are seeking an experienced R&D Software Developer focused on C++ application development for performance-critical systems to join our technology organization.

In this role, you will develop, high-performance, and secure software systems built with modern C++ (C++17/20), with a strong focus on real-time behavior, reliability, and long product lifecycle support.

Responsibilities:

• Develop system design in areas like multithreading, synchronization, I/O, and latency requirements for real-time operation.
• Develop high-performance C++ cores to managed runtime services (.NET, RUST) with minimal latency overhead.
• Implement performance optimization and scalability: profile threading behavior, minimizing lock contention, reducing memory allocations in critical paths, and ensure predictable latency at scale.
• Practical usage of modern programming practices and techniques based on the latest C++ standard.
• Maintain high code quality through code reviews, unit testing, and adherence to SOLID, KISS, DRY and industry best practices.
• Participate in technical architecture reviews, design documentation, and roadmaps for feature development.
• Collaborate with engineering, product, and business stakeholders.
• Support strategic technology decisions on dependencies, build tooling, dependency management, and secure software supply chain practices.
• Maintain cross-platform support: drive modernization of build systems, ensure consistency across multiple deployment environments, and support Linux/Windows compatibility.
• Practical Linux development and deployment strategies.
• Work effectively within an agile environment.

Requirements:

• 8+ years of experience in senior technical roles.
• Advanced proficiency in modern C++ (C++17/20) with deep understanding of RAII, smart pointers, STL, concurrency, and memory management.
• Practical knowledge of C# development in plus.
• Strong experience with multithreading, synchronization primitives, asynchronous I/O and real-time system design.
• Proficiency with building systems (CMake, Visual Studio) and cross-platform development for Windows and Linux.
• Experience with containerization technologies (Docker, Kubernetes) and microservices architecture patterns.
• Good understanding of unit and integration testing techniques and testing frameworks.
• Practical experience developing systems monitoring having familiarity with WAMS/WAMPAC, PMU data, and protection and control applications.
• Practical experience working directly with power grid industry clients and exposure to system integration, simulators, or lab environments.
• Good understanding of power system dynamics and the stability challenges introduced by high penetration of renewables
• Excellent command of English.

What can you expect:

• Team of passionate people who love what they do.
• Opportunity to learn and grow.
• Private Medical Care - INTER Polska.
• Co-funded Multisport Card.
• Possible training or certification subsidies.
