Tech Lead C++

The Technical Leader is the technical authority for C++‑based applications, responsible for technical design, implementation quality, performance, and long‑term sustainability of the systems delivered by the team.
Building on strong C++ expertise, the Technical Leader guides, coaches, and enables the team, while remaining actively involved in complex technical topics and architectural decisions.

What you will do:

Technical Leadership & Architecture

• Act as the technical reference for C++ development within the team.

• Define and co‑design the technical architecture in collaboration with the team and architects.

• Ensure high‑performance, low‑latency, and reliable designs for critical systems.

• Validate technical choices, frameworks, and libraries used in the C++ stack.

• Guarantee coherent integration of the application within the global Information System.

Hands‑On Development

• Contribute directly to complex or critical C++ developments.

• Review and validate code to ensure robustness, performance, and maintainability.

• Support the team in troubleshooting production issues, performance bottlenecks, and memory issues.

• Promote modern C++ standards and best practices (C++17/20).

Quality, Performance & Reliability

• Be accountable for:

  • Code quality and technical debt management

  • Performance, latency, and scalability

  • Stability and resilience of production systems

  • Security and obsolescence management

• Ensure quality is a shared responsibility across the team.

• Promote engineering best practices:

  • Clean code

  • Unit and integration testing

  • Code reviews

  • Continuous refactoring

Team Enablement

• Support the team during technical design sessions, refinement, and problem‑solving workshops.

• Coach developers on C++ best practices, performance optimization, and system design.

• Facilitate knowledge sharing and skill transfer within the team and technical chapter.

• Help the team become autonomous and accountable for technical decisions.

Technology Watch & Continuous Improvement

• Maintain an active technology watch on C++, tooling, compilers, performance profiling, and architectures.

• Initiate and contribute to Proofs of Concept (PoCs) when relevant.

• Improvement of development practices and tooling.
