Project Description

Development of a portable, high-fidelity audio device integrated with AI assistant capabilities. The project focuses on creating a high-performance consumer electronics product with a focus on quality sound and battery efficiency.

Scope of Work

You will be responsible for the “brain” of the device, from low-level drivers to high-level application logic.

• Firmware Development: Design and build applications, system features, and peripheral drivers from scratch.
• Full-Cycle Engineering: Handle coding, debugging, and systematic troubleshooting throughout the entire development process.
• System Validation: Perform rigorous testing to ensure hardware-software stability and feature performance.

We Expect You Are

• Self-Driven & Autonomous: A proactive problem-solver who can navigate hardware documentation and drive tasks to completion independently.
• Result-Oriented: Focused on delivering high-quality end products that align with business goals and reach the “Done” state.
• A Strong Communicator: Able to articulate complex technical concepts clearly to both technical and non-technical stakeholders.
• Flexible: Ready to quickly adjust to changing requirements, new technology stacks, or shifting project priorities.
• Value-Driven: A contributor who looks beyond “just coding” to propose architectural improvements and process optimizations.
• A Collaborative Team Player: Committed to knowledge sharing, active participation in code reviews, and supporting colleagues.

What You Need For This Position

• 5+ years in embedded software development with broad system-level thinking and a focus on product architecture.
• Deep proficiency in C/C++, including memory management, interrupts, and real-time constraints.
• In-depth knowledge of Linux (Yocto/Buildroot, kernel-level debugging, device trees) and RTOS (FreeRTOS or similar) internals.
• Previous experience with audio processing (either on DSP or ARM Helium MVE).
• Experience with embedded ML or Edge Computing.
• Proven track record in debugging, bug fixing, and system performance optimizations.
• Strong experience with peripheral (UART, SPI, I2C).
• Proficiency in CMake, Bash, and Python scripting for automation and build systems.
• Solid experience with Git, GitHub, and Jira.
• Ability to create clear, maintainable technical specifications and code documentation (Doxygen, Wiki, Markdown).
• English Proficiency: Upper-Intermediate (B2). Ability to conduct technical discussions, participate in meetings, and write professional documentation/emails for international clients.
   

Nice to Have

• Ability to read datasheets/schematics and hands-on experience with oscilloscopes and logic analyzers.
• Familiarity with ZephyrOS.
• Experience with embedded ML or Edge Computing.
• Experience with wireless connectivity: BLE, WiFi, Matter, LoRaWAN.
   

What We Offer For Your Success

• Zero bureaucracy and no time tracking;
• 20 working days paid vacation and 15 days of sick leave;
• Additional days of leave for important events of life;
• Flexible working hours (start your day between 8:00 and 11:00);
• Professional English courses in small groups by level;
• Education and anniversary bonuses;
• Providing all the necessary equipment;
• Full accounting support for the employees;
• The opportunity to rotate on projects to learn new technologies;
• Opportunity for development and career growth in the areas of Tech/Team leadership, mentoring;
• Office in the historical part of Kyiv (Podil) with convenient transport links;
• Office with autonomous power systems, uninterrupted Internet connection, coffee, tea, and snacks.
   

Hiring Process

Stage 1: Interview with HR (60 min.).

Stage 2: Technical Interview (60-80 min).

About the Product:

Cynet is a unified, AI-powered cybersecurity platform that autonomously detects, protects, and responds to threats across Windows endpoints.

The core product is a Windows EDR agent that runs on hundreds of thousands of devices, offering real-time detection, prevention, and response with minimal resource impact.

Built for organizations of all sizes, it consolidates threat detection, response, and compliance into a single agent and console, backed by 24×7 MDR experts.

The platform addresses the industry challenge of growing cyber threats by delivering fast, accurate protection without noise or complexity.

About the Role:

As a Windows C++ Developer, you will join the award-winning Windows EDR team and drive low-level development on the heart of Cynet’s protection platform.

You will design and implement core components in a user-mode, multithreaded environment, owning features end-to-end from architecture through deployment.

Your work will directly impact hundreds of thousands of Windows endpoints, shaping detection and prevention capabilities and ensuring product stability at scale.

This role combines deep technical challenges in Windows internals, performance tuning, and real-time programming with cross-team collaboration among security researchers, product managers, and support engineers.

You will have autonomy to propose solutions, influence architectural decisions, and take ownership of critical features that define the product’s competitive edge.

Key Responsibilities:

• Design and implement user-mode services and low-level components for the Windows EDR agent
• Develop multithreaded applications with thread synchronization and real-time constraints
• Collaborate with security researchers to translate detection rules into code
• Own feature lifecycle: design, coding, performance tuning, and integration
• Debug escalated customer issues, analyze logs, and perform remote debugging sessions
• Conduct code reviews and ensure adherence to OOP and clean coding principles
• Write and maintain unit tests and automation scripts within the existing framework
• Optimize memory management, I/O performance, and resource usage for large-scale deployments
• Participate in sprint planning, PI design sessions, and architectural discussions

Required Competence and Skills:

• 4+ years of experience in C++ development on Windows (modern C++17/20/23 – an advantage)
• Deep understanding of Windows OS internals and Windows API
• Proven experience with multithreaded programming, synchronization, and real-time constraints
• Strong software design, OOP, and clean coding practices
• Expertise in memory management and I/O performance optimization
• Proficient debugging skills, including remote debugging and log analysis
• Familiarity with smart pointers (shared_ptr, unique_ptr) and move semantics
• Experience writing unit tests and integrating automation tests

Nice to Have:

• Kernel-mode development experience
• Background in reverse engineering or malware analysis
• Prior experience in security-oriented software development
• IDF Cyber Unit alumni
