COO / CTO Co-founder (Accounting AI & Process Automation)

About the role

We are looking for a COO / CTO Co-founder to co-build an AI-driven startup focused on automating accounting and financial operations for modern businesses. This is a hands-on founder role, not a corporate executive position. You will be responsible for shaping both the technological and operational foundations of the company — from defining the product architecture and automation logic, through building scalable delivery processes, to co-managing the company together with the founding team.

In the early stage, you will work directly on turning complex accounting workflows into reliable, repeatable and AI-supported solutions. Your mission will be to build a product and operating model that can scale: combining AI, automation, process design, product thinking and strong execution in a high-uncertainty, pre-PMF environment.

Your responsibilities

As COO / CTO Co-founder, you will be responsible for:

• Co-managing the company together with the founding team and aligning technology, operations and business goals
• Shaping and iterating the product vision for an AI-powered accounting automation platform
• Translating accounting and financial workflows into scalable, automated and AI-supported solutions
• Defining the product architecture, automation logic, integrations and data flows
• Leading the development of automation pipelines and technical foundations of the platform
• Designing operational processes from scratch, including customer onboarding, delivery, support and continuous improvement
• Establishing execution frameworks, project management standards and internal operating rhythms
• Ensuring high standards of reliability, security, scalability and compliance awareness
• Monitoring AI, automation, fintech and accounting-tech trends and applying them to product and operational strategy
• Optimising efficiency, time-to-value and customer satisfaction
• Building and leading a small, high-impact technology and operations team
• Creating a company culture based on ownership, accountability, speed and excellence
• Supporting investor communication, pitch preparation and technical/product due diligence
• Overseeing technology- and operations-related planning, including budgeting, forecasting and resource allocation

Who we are looking for (Must-have)

• At least 5+ years of leadership experience in startups, scale-ups or technology-driven companies
• At least 3+ years in roles such as CTO, COO, VP Engineering, Head of Product, Head of Operations or equivalent
• Proven experience in building products, platforms, automation systems or operational processes from scratch
• Hands-on experience with automation, AI, process improvement or workflow optimisation projects
• Strong understanding of product development, technical architecture and scalable systems
• Solid knowledge of project management, process design and execution frameworks
• Entrepreneurial mindset - you understand that in an early-stage startup, ownership, speed and pragmatic execution matter more than perfect structures
• Strong analytical and problem-solving skills
• Ability to operate effectively in a fast-paced, ambiguous and pre-PMF environment
• Excellent communication skills and the ability to translate business needs into technical and operational solutions
• Fluent Polish and English, both spoken and written

Nice to have

• Experience in accounting, fintech, ERP, financial operations or back-office automation
• Experience with B2B SaaS products or platforms
• Experience integrating AI into production systems
• Background in workflow automation, document processing, data extraction or financial process automation
• Experience scaling technical or operations teams
• Previous fundraising experience or collaboration with investors
• Ability to explain complex technical and operational topics to non-technical stakeholders
