Call2action AI — HR/AI Startup (USA Market)
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.
