# Growth Manager

**Semji** · Lyon, FR

Join Semji, a company dedicated to building growth engines. As a Senior Growth Manager, you will be responsible for architecting the acquisition machine, optimizing lead flow, and developing custom dashboards for data analysis. You should have expert-level SQL skills, advanced workflow automation experience, and a deep understanding of HubSpot CRM architecture. The ideal candidate will have a startup/scale-up background or previous technical roles.

### Key Missions

### Profile
You are a “mission-driven” builder with an autodidact mindset. You don’t wait for a manual; you find the documentation and solve the problem yourself.

**Hard Skills (Required):**
- **Data & SQL:** Expert-level SQL (specifically BigQuery).
- **Workflow Automation:** Advanced n8n workflow design.
- **Development Tools:** Experience with GitHub for version control and Claude Code for rapid script prototyping.
- **CRM Mastery:** Deep understanding of HubSpot CRM architecture.

**Soft Skills:**
- **Problem-solving Orientation:** You see technical friction as a challenge to overcome, not a roadblock.
- **Independence:** You are comfortable working in a fast-paced environment where you define the technical “how.”

**Experience:**
- Strong preference for candidates with Startup/Scale-up backgrounds or previous Technical Roles (Growth Engineer, Data Ops).
- *Note:* We value hands-on execution. Former consultants will only be considered if they demonstrate a strong match with the technical requirements above.

(2 to 3 weeks)

- Hiring manager interview with Yannick (Chief Ops Officer)
- Use case with Arnaud (revops) and Yannick
- CEO fit itw with Bertrand (CEO)
