Qualifications

• University degree in computer science, engineering, or a related technical field.
• 10+ years of experience in senior technical or architecture roles.
• Advanced proficiency in modern C++ (C++17/20) with deep understanding of RAII, smart pointers, STL, concurrency, and memory management.
• Proven 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; demonstrated experience with performance profiling, optimization, and low-latency system; good understanding of software architecture principles and secure, scalable system design.
• Good understanding of unit and integration testing techniques and testing frameworks.
• Experience with Cloud, DevOps, deep cybersecurity expertise, UI/web development.
• Knowledge of non-functional requirements (performance, scalability, security).
• Practical experience developing systems for power grid management and monitoring having familiarity with WAMS/WAMPAC, PMU data, and protection and control applications; understanding of power grid operations and applicable standards; experience with industrial automation systems (SCADA, IED, RTU).
• Experience with industrial protocols and standards (IEC 61850, IEC-60870-5-104, DNP3, OPC UA, IEEE C37.118).
• Practical experience working directly with power grid industry clients and exposure to system integration, simulators, or lab environments
• Proven ability to translate customer requirements into clear technical designs.
• Solid understanding of numerical methods, signal processing, and control fundamentals and ability to work with high-frequency, time-aligned time-series data
• Good understanding of power system dynamics and the stability challenges introduced by high penetration of renewables
• Excellent problem-solving skills and the ability to tackle complex technical challenges; effective team player with good communication skills and willingness to learn.
• Excellent command of English (written and spoken).

Responsibilities

• Lead system design in areas like multithreading, synchronization, I/O, and latency requirements for real-time operation.
• Architect interop layers connecting high-performance C++ cores to managed runtime services (.NET, RUST) with minimal latency overhead.
• Drive performance optimization and scalability: profile threading behavior, minimizing lock contention, reduce memory allocations in critical paths, and ensure predictable latency at scale.
• Propagate 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.
• Mentor development teams on system design, best practices and maintaining code quality in performance-critical sections.
• Lead technical architecture reviews, design documentation, and roadmaps for feature development, refactoring initiatives, and legacy code modernization.
• Collaborate with engineering, product, and business stakeholders to transform requirements into clear architectural designs.
• 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.
• Drive Linux development and deployment strategies: architect solutions for Linux environments.
• Contribute to achieving business goals by designing, developing, and delivering high-quality software solutions.
• Continuously enhance existing systems and contribute to the creation of new features.
• Work effectively within an agile environment, continually expanding your technical expertise and understanding of the business domain.
• Actively participate in a cross-disciplinary team and contribute to shared objectives.
