## Core Business
- **Primary industry**: Technology consulting / AI Engineering
- **Target customers**: B2B, Enterprise (large organisations seeking AI transformation)

## Market Standing

## Competitive Advantages
- **AI Only focus**: Entirely dedicated to AI-driven engineering – not a generalist consultancy. Every consultant is trained and deployed on generative AI.
- **Augmented Engineer model**: Engineers write 80% less boilerplate code but own architecture, security, and business relevance. AI handles mechanics; humans drive value.
- **Collective intelligence**: 850+ engineers with internal events every week, dozens of thematic communities, and a culture of test-and-learn. No one is alone on a hard problem.
- **Skills‑based organisation**: Career progression defined by real skills (up to 13 per role), not by title. Two parallel tracks: Individual Contributor (Staff, Principal, Senior Principal) and Engineering Manager.
- **PlayOffs hiring process**: Half-day pair‑programming with three Sfeirians – candidates assess the company as much as they are assessed. No timed quizzes or whiteboard riddles.

## Strategic Focus
- **AI‑driven transformation**: Helping clients move from marginal gains to 10x productivity through generative AI, context engineering, and the Agentic Conversational Enterprise.
- **Continuous upskilling**: 100% of consultants go through the AI Champions programme; internal RAISE platform provides access to latest LLMs; SFEIR Institute delivers certified training.
- **Scaling the tribe**: Expanding engineering headcount across France and Benelux, with new roles published weekly in software, cloud, data, AI, and architecture.

## Why Work Here
- **Culture**: A “tribe” of engineers where real skill outranks the job title. Flat hierarchy, managers who still code, and five values: kindness, inclusiveness, excellence, freedom, responsibility. [sfeir.com](https://www.sfeir.com/en/company/culture/)
- **Remote/Hybrid/Office**: 8 offices across France and Benelux; the hiring process is on-site (half-day PlayOffs), indicating a strong office‑centric culture, though flexible arrangements may be available on a per‑project basis (not explicitly stated).
- **Notable perks**: Permanent learning (SFEIR Schools, certified training, RAISE platform); strong support for personal branding (writing on sfeir.dev, speaking at conferences like Devoxx, DevFest, Google I/O); no sales targets – only tech level and tech culture count.
- **Engineering culture**: Pair‑programming hiring, AI‑first tooling (Claude Code, Cursor, LangGraph, Gemini Enterprise), and a promise of lasting employability through continuous skill evolution.
