Senior Growth Manager

🚀 The Mission

At Semji, we don’t just “do marketing”; we build growth engines. We are looking for a

Senior Growth Manager

to architect the “plumbing” of our acquisition machine. You aren’t just managing campaigns; you are using code and automation to scale outreach, enrich data, and ensure leads flow seamlessly from discovery to HubSpot.

🛠️ Key Responsibilities & Achievements

• Outbound Engineering:

  Build and maintain fully automated outbound sequences using enrichment APIs and n8n to deliver hyper-personalized prompts directly to Lemlist.

• Data Architecture:

  Develop custom dashboards in BigQuery/Looker Studio to track and analyze lead conversion rates across various experimental segments.

• Lead Flow Optimization:

  Ensure the data pipeline—from initial scraping or lead capture to HubSpot—is robust, enriched, and scalable.

• Rapid Prototyping:

  Leverage Claude Code and AI tools to script quick solutions and automate repetitive growth tasks.

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.
