Job description

We are looking for an experienced C++ Technical Lead to lead the design, development, and optimization of high-performance software solutions. In this role, you will serve as a technical authority, driving innovation, architectural decisions, and best practices across engineering teams. You will work on complex systems, ensuring scalability, efficiency, and maintainability while mentoring engineers and collaborating with cross-functional teams.

We are growing fast as a company and do our best to bring our SaaS cloud-based backup services to the global audience.

Our platform is designed to provide customers with an immutable historical archive of their primary data in systems such as Microsoft 365, Google Workspace, Salesforce, Entra ID, Dynamics 365, and Zendesk. It aims to protect them against everything, starting from ransomware to simple accidents.

Most of our back-end components are written in clean, modern C++ using mainly purpose-built components and STL. Several components that deal with business processes and data mining are built using Common Lisp. Everything runs on Linux.

Backing up billions of objects over foreign APIs using imperfect networks on systems with finite memory and making it all happen in as little time as possible is no small feat.

Key Responsibilities:

• Problem Solving: Understand business challenges and translate them into effective technical solutions. Take ownership of complex problems, proactively identifying and implementing improvements to our systems.
• Technical Leadership: Define and drive the technical vision, strategy, and best practices for C++ development across teams.
• Software Architecture & Design: Design and implement highly efficient, scalable, and maintainable C++ applications.
• Code Quality & Performance: Ensure best coding practices, conduct rigorous code reviews, and optimize for high-performance and low-latency systems.
• Collaboration & Mentorship: Work closely with cross-functional teams (product, DevOps, QA) and mentor junior/mid-level engineers to improve technical expertise.
• Security & Compliance: Ensure adherence to security standards, data integrity, and compliance best practices.
• Technology Evaluation & Innovation: Stay up to date with the latest C++ standards, incorporating relevant technologies into projects.

Required Qualifications:

• Experience: 10+ years of professional C++ development experience, with deep expertise in modern C++ (C++11/14/17/20).
• Software Architecture: Proven track record in designing scalable and modular software architectures.
• Multithreading & Performance Optimization: Strong knowledge of concurrent programming, memory management, and performance tuning.
• Algorithms & Data Structures: Expertise in designing and implementing efficient algorithms for performance-critical applications.
• Debugging & Profiling: Experience with tools like GDB, Valgrind, perf, or equivalent for analyzing and troubleshooting software performance issues.
• CI/CD & Version Control: Proficiency in Git, CI/CD pipelines, and DevOps best practices.
• Leadership & Communication: Strong leadership, collaboration, and technical decision-making abilities.

Preferred Qualifications:

• Proactive problem solver with a strong business mindset
• Strong experience with C++ in high-performance, scalable systems (preferably in a SaaS environment).
• Familiarity with backup, storage, or data protection technologies
