About the Company 

At WOWCube®, we’re redefining play with a one-of-a-kind cube-shaped gaming console that merges the physical and digital worlds. 

The WOWCube Entertainment System combines modular hardware, immersive software, and creative game design to create a brand-new category of interactive entertainment. We are a fast-growing, innovative game development studio pushing the boundaries of interactive entertainment.

About the Role 

We are looking for a highly skilled and experienced Senior C/C++ Developer (Embedded / Game & Systems Software Engineer) with a strong background in low-level development, game engines, and resource-constrained environments.

In this role, you will be responsible for designing software architecture, building gameplay systems, and optimizing performance under strict hardware limitations. You are a perfect fit if you are comfortable with real-time constraints, embedded-like platforms, and taking end-to-end ownership of features - from design and implementation to debugging on real devices.

Key Responsibilities

• Design and develop core game logic and architecture using C/C++ (including game state design and event-driven gameplay).
• Implement essential gameplay systems, such as AI, game state machines, and custom GUI.
• Work on 2D programming and special effects finely tuned and optimized for resource-constrained hardware.
• Design high-performance, asynchronous architectures, network pipelines, and queue-based systems with low-latency requirements.
• Perform performance tuning, profiling, memory diagnostics, and crash analysis.

• Collaborate closely with technical artists and designers; develop internal tooling, custom engine features, and automation scripts to streamline production.

   

Requirements

• 5+ years of experience in low-level C/C++ development across mobile, console, or embedded-like platforms.
• Solid understanding of gameplay and engine programming concepts, including rendering pipelines, memory management, and hardware optimization.
• Familiarity with RTOS or real-time concepts (tasks, priorities, timers, scheduling) and event-driven systems.
• Strong networking skills, including experience with TCP/IP, UDP, WebSockets, and non-blocking I/O operations.
• Proficiency with development tools, version control systems (GCC, CMake, Git, SVN, Perforce, etc.), and build-deploy automation.

Desirable Pluses

• Experience with platform compliance and certification processes (e.g., Nintendo TRC, Sony TRC, or similar vendor requirements).
• Experience with multiple programming languages and environments (e.g., Rust, Java, TypeScript, Python, Bash, Lua, Android NDK/SDK, or AOSP).
• Familiarity with multimedia and audio/video frameworks (SDL2/SDL3, Raylib, GStreamer, FFmpeg, ALSA, Vorbis, etc.).
• Experience in complex automation or integrating game software with specific physical hardware layouts/models.

What We Look for in Your Application

• An updated CV highlighting your technical stack and the commercial or shipped projects you have been part of.
• Examples (or GitHub links) demonstrating how you have approached complex architectural challenges or performance optimisations in hardware-limited environments.

We are looking for a Linux Administrator to support high-performance computing environments and critical distributed infrastructure.
 

In this role, you will:

• Administer HPC clusters for machine learning workloads (e.g., Slurm, Ceph)
• Maintain and support application infrastructure (web services, ERP systems, mail, LDAP, messaging services, etc.)
• Manage and automate workstation provisioning using Ansible
• Ensure stability, performance, and security of distributed systems
   

Requirements:

• Strong experience in Linux system administration (Ubuntu/Debian preferred)
• Strong C++ knowledge or experience working with C++ environments
• Experience with HPC environments and job schedulers (e.g., Slurm)
• Knowledge of distributed storage systems (e.g., Ceph or similar)
• Experience with infrastructure automation tools (e.g., Ansible)
• Solid understanding of networking fundamentals and security best practices
   

Nice to have:

• Experience with Python, Rust, or CUDA
• Familiarity with low-level Linux systems or kernel concepts
• Experience with web or backend systems
   

What we offer:
Work on cutting-edge autonomous driving tech, flexible hours, fast-paced engineering environment, competitive salary, and stock options.
