Principal Software Engineer vs Engineering Manager: Salary & Career Benchmarks in France

In France, Engineering Manager roles typically command a higher median salary than Principal Software Engineer positions. According to our 2026 live benchmark data, a mid-level Engineering Manager earns a median salary of €81K, whereas a Principal Software Engineer brings in roughly €1K (a gap of €80K at the median).

Seniority, tech stack, and location all move this gap. Senior practitioners in either discipline can exceed the upper range through specialist skills. See the skills premium section below for the specific certifications and tools that push offers to the top of the range.

While both positions are vital to a modern tech organisation, Principal Software Engineer and Engineering Manager have fundamentally different daily workflows.

Principal Software Engineer focuses primarily on driving technical direction, architecture decisions, and engineering standards across multiple teams. Day-to-day work revolves around writing and reviewing RFCs, prototyping architectural solutions, mentoring senior engineers, driving cross-team technical alignment, and contributing to complex code in the highest-risk areas of the codebase.

Engineering Manager focuses on leading engineering teams, managing delivery, and developing engineers through coaching and career development. Their time is spent running 1:1s and team rituals, reviewing and unblocking pull requests, managing roadmap and delivery planning, recruiting and onboarding engineers, and aligning with product and commercial stakeholders.

Transitioning between these two paths is achievable but requires targeted upskilling.

Moving from Principal Software Engineer to Engineering Manager: Senior Software Engineers or Staff Engineers are the typical pipeline. The hardest part of the transition is shifting from producing code to producing outcomes through other people. Many companies now offer structured EM training programmes.

Moving from Engineering Manager to Principal Software Engineer: Senior Software Engineers who have demonstrated impact beyond their immediate team, driven architectural decisions, and mentored others are the standard path. The jump requires a mindset shift from team-level to org-level impact.

Neither path requires starting from scratch. Professionals in both roles share underlying technology fluency; the gap is usually domain knowledge and specific tooling rather than core engineering fundamentals.

In France in 2026, both roles are seeing demand, but with different drivers.

Principal Software Engineer demand is high, particularly in Enterprise software and fintech engineering organisations in Paris and Toulouse, led by employers such as Dassault Systemes and Criteo. Engineering Manager demand is high, concentrated in engineering organisations scaling their Paris and Lyon hubs, led by employers such as Doctolib and Criteo.

Workspace flexibility significantly impacts total compensation value in France.

Principal Software Engineer roles score 70% on our remote-friendliness index (High). This is because technical design and deep coding work is async and remote-compatible, and French employers have leaned into remote and hybrid arrangements since teleworking negotiations became standard practice across Paris tech scale-ups. Where in-office attendance is required, it is typically driven by architectural alignment sessions, mentoring, and cross-team technical reviews benefit from in-person presence, which is why Paris-based scale-ups increasingly schedule fixed in-office days around sprint planning and design reviews.

Engineering Manager roles score 55% (Moderate). Some management work (documentation, async communication, and strategy) is remote-compatible, though French labour law's right-to-disconnect provisions typically cap EM remote schedules at two or three days rather than full flexibility is the primary driver of flexibility. When office days are required, it is usually for team coaching, relationship building, hiring panels, and cross-functional alignment are significantly more effective in person, and Paris-based scale-ups like Doctolib still run hiring panels and 1:1 rituals with a strong in-office expectation.
