Co-Founder & CTO

Summary

Join a pre-seed funded AI-native platform venture building an enterprise business modelling and scenario planning platform to replace Excel. As the Founding CTO, you will shape the technical vision, build core systems, and lead a world-class engineering team. The role involves designing a scalable modelling engine, integrating AI/LLM capabilities, ensuring enterprise-grade security and performance, and leading product development. You will also build and lead a high-performing engineering team. The company is establishing its HQ in Helsinki but offers hybrid or remote arrangements. This is a founding opportunity to build something ambitious from scratch and have real ownership over product and technology.

Requirements

• You’ve architected and shipped technically complex products from the ground up - ideally involving graph databases or large-scale data modelling systems
• You have deep knowledge of the AI/LLM ecosystem and experience applying it meaningfully in production environments
• You’ve built secure, scalable SaaS products used by enterprise customers, balancing technical rigour with real-world constraints
• You’ve led high-performing engineering teams through the 0-1 phase and know how to scale talent, systems, and processes without overengineering
• You’re a strong communicator, able to represent the company credibly to investors, enterprise clients, and future hires
• You’re pragmatic, collaborative, and thrive in fast-paced, ambiguous environments where priorities evolve quickly

Responsibilities

• Design and build a scalable, flexible modelling engine combining graph and grid systems
• Integrate AI and LLM capabilities deeply into user workflows
• Ensure the architecture enables rapid iteration while meeting enterprise-grade security and performance standards, using a modern stack including Fastify, Next.js , Kafka, Neo4j, and a Go- or Rust-based calculation service
• Lead development of the initial product and shape the roadmap alongside the CEO, ensuring strong alignment between product and engineering
• Build and lead a high-performing engineering team to support product growth, technical excellence, and long-term scale

Preferred Qualifications

You’ve worked with event-driven architectures, FP&A tooling, or graph-based platforms

Benefits

• This is a true founding opportunity - you’ll be shaping the technical foundations and future of the company from day one
• We’re building with cutting-edge technologies, solving hard and meaningful problems, and backed at pre-seed to move fast
• If you want to build something ambitious from scratch and have real ownership over product and tech, we’d love to speak with you
