Senior / Principal C++ Developer (Linux Systems)

About the Role:
We're seeking a Senior or Principal-level C++ Developer who can operate at the highest technical level - someone who doesn't just write code, but owns entire features, makes architectural decisions, and drives technical excellence.

This is a role for experienced engineers who:

• Have mastered modern C++ and can architect complex systems independently
• Thrive with minimal supervision and full technical autonomy
• Can take a feature from initial concept through to production deployment
• Are ready to collaborate as equals with other senior/principal engineers in a lean, high-performing team

You'll work on performance-critical applications in Linux environments where your decisions matter and your expertise shapes the product.

Technical Stack

Core Technologies:

• C++17 / C++20 / C++23 / C++26 (modern standards)
• Linux: GCC, Clang, GDB, Valgrind, CMake

• STL, templates, smart pointers, move semantics, lambdas

Focus Areas:

• Distributed systems and computation
• Concurrency and performance optimization
• Scalability and memory management

Key Responsibilities

What Principal/Senior Level Means Here:

• Full Feature Ownership: You own features from concept → architecture → implementation → deployment. No hand-holding.
• Architectural Leadership: Design and architect modern C++ applications for Linux environments - your decisions shape the system
• Technical Authority: Participate in deep technical discussions, provide architectural guidance, conduct thorough peer code reviews
• Complex Problem Solving: Tackle challenging problems in distributed systems, scalability, and performance optimization
• Peer Collaboration: Work directly with other senior/principal engineers as equals in an autonomous, lean setup

This isn't a role where you execute tickets - you define them, architect solutions, and see them through.

Required Qualifications

Seniority Level:

• 8+ years of production C++ development experience
• Principal or Senior-level expertise - you should be comfortable making architectural decisions independently
• Proven track record of owning complex features end-to-end
• Experience mentoring or guiding other engineers (even informally)

Technical Expertise:

• Mastery of modern C++ (C++17/20/23/26) - not just familiarity
• Deep expertise in STL, templates, smart pointers, move semantics, lambdas
• Strong foundation in algorithms, data structures, memory management, and concurrency
• Hands-on experience architecting and debugging complex Linux-based systems
• Ability to work autonomously and make technical decisions with minimal supervision

Soft Skills:

• Strong ownership mindset - you take full accountability for your technical decisions and delivery
• Attention to quality and detail at every development stage
• Excellent technical communication - can explain complex concepts clearly
• Comfortable with asynchronous collaboration in distributed global teams
• Adaptable to changing priorities and evolving technical challenges
• Proactive problem-solver with transparent progress reporting

Language:

• Advanced English (C1) for direct client communication and technical discussions

Nice to Have:

• Experience with performance-critical or distributed systems
• Client-facing experience and ability to translate technical concepts
• Track record of architectural decisions in complex projects
• Contributions to open-source or technical communities

What We Offer

Work Environment:

• Lean, autonomous engineering setup
• No bureaucracy - focus on building great software
• Direct collaboration with other senior/principal engineers
• Respectful peer communication and knowledge sharing culture

Professional Growth:

• Cutting-edge projects with modern C++ standards
• Full technical autonomy and decision-making authority
• Opportunity to shape architecture and technical direction
