Role Mission

The Head of Sales is accountable for leading the sales function and driving growth by designing, building, and scaling an AI- and automation-powered sales engine that delivers a predictable pipeline and revenue growth, increases conversion speed and efficiency, and outperforms traditional agency sales models through data-driven experimentation and disciplined execution.

Key responsibilities

• Lead the transformation of sales into a scalable, AI- and automation-enabled operating model where repetitive work is automated, and the team focuses on higher-value activities: experimentation, process improvement, relationship-building, and conversion quality.
• Define the architecture of sales processes, communicate requirements and set priorities for the implementation team, and continuously improve automation and AI workflows to ensure they outperform manual execution and fit the company’s broader ecosystem as the business scales.
• Improve outreach effectiveness through sharper ICP and buyer persona definition, higher targeting quality, and continuous optimization of AI-assisted messaging, prompts, and workflows.

• Referral program development.
• Sales calls.
• Reactivation of former clients and lost opportunities.
• Sales knowledge systems and documentation, with Notion serving as the source of truth.

Execution may be delegated — ownership is not.

Required Competencies

• Strong B2B service sales leadership experience, ideally in IT staffing, recruitment, or tech services.
• Proven ability to build repeatable outbound and multi-channel lead generation systems.
• Strong bias toward action, experimentation, iteration, and continuous improvement.

• Able to design commercial processes that are scalable, measurable, and repeatable.
• Uses data to challenge assumptions, improve decisions, and constructively raise performance standards.
• Able to operate both strategically and hands-on in a growing company environment.
• Proven ability to hire, coach, and scale a sales team with clear ownership and accountability.
