Call2Action AI is a fast-growing, founder-led startup building AI-powered products for the US hiring and trucking market. We’re on a mission to transform how companies hire, screen, and communicate with candidates using intelligent agents and automation.

We are looking for a hands-on CTO who is not just a manager, but a builder, architect, and technical co-creator of the company. Someone who lives and breathes startups, loves shipping real products, and wants massive impact.

This is a key leadership role with real ownership over technology, product architecture, and the future of our AI platform.

🔥 What you will do

• Own the entire technical vision and execution of the company.

• Design and evolve the system architecture: AI layer, backend, infrastructure, integrations, scalability.

• Build and lead the engineering function from early stage to growth.

• Actively code (especially at early stages): Python, AI pipelines, backend services.

• Drive development of AI agents: LLM integrations, RAG systems, NLP, voice pipelines (ASR/TTS).

• Make core decisions on stack, infrastructure, security, and performance.

• Work closely with founder on product strategy and roadmap.

• Integrate AI systems with CRMs, external APIs, and client platforms.

• Establish engineering culture, best practices, and hiring standards.

🧠 What we’re looking for

• Strong background in Python (backend + AI/ML).

• Proven experience with AI/ML systems: LLMs, NLP, agents, or production ML pipelines.

• Deep understanding of system architecture and building scalable products from scratch.

• Experience with cloud infrastructure, APIs, databases, and modern backend frameworks.

• Ability to combine strategic thinking with hands-on execution.

• Startup mindset: ownership, speed, responsibility, and comfort with uncertainty.

• Strong communication skills and ability to work directly with founder and clients.

• Willingness to sometimes join late calls due to US clients and partners.

⭐ Big plus if you have

• Experience building AI products or AI startups.

• RAG systems, vector databases, multi-agent architectures.

• Voice agents (ASR/TTS), automation platforms, or HR-tech.

• Hiring and scaling engineering teams.

💎 What we offer

• A true CTO role — not just a title, but real influence and ownership.

• Opportunity to design the full tech and AI architecture of a US-focused startup.

• Direct impact on product, strategy, and company growth from day one.

• Fast execution, short feedback loops, and zero corporate bureaucracy.

• Strong, ambitious founding team building for a massive market.

• Competitive compensation (based on experience) + long-term growth potential.
