Founding Engineer

Circonomit
Germany · Full-time · Associate

At Circonomit, we're dedicated to revolutionising how organisations perceive and manage their resources. Our mission is to build the strategic twin of organisations—a sophisticated control system that comprehensively understands the true impact of time, money, and resources. We are committed to eliminating adverse outcomes resulting from hidden interdependencies, enabling organizations to operate more efficiently and sustainably. We are seeking a Founding Engineer as the second brain next to our CTO with full-stack responsibility. In this role, you will take key ownership of building intuitive, powerful tech that makes system-level interdependencies usable and scalable. As a key contributor, you will split critical work in code, architecture, and deployment with Erik. If you are passionate about models and strategic decision-making and thrive in a fast-paced, nerdy environment, we would love to hear from you!

Responsibilities

  • Design and develop core components of the strategic twin control system in the full stack
  • Prototype fast and smart, testing, learning, and delivering between AI and UX
  • Own a proactive role in drafting and implementing software architecture, computational logics, and scalable infrastructure
  • Write clean, maintainable, and efficient code on top of what AI can not deliver
  • Participate in code reviews and ensure adherence to best practices
  • Troubleshoot and debug system issues to ensure high availability and performance
  • Collaborate with the founding team to consistently translate the big picture into outcomes

Requirements

  • 3+ years of experience in software development, preferably in a founding or startup environment
  • Strong proficiency in programming languages such as TypeScript and SQL
  • Solid experience with frameworks such as React, Solid.js, and LangChain
  • Experience with cloud-based technologies and architecture
  • Solid experience in the abilities and the boundaries of AI, the use of language models, prompt engineering, and retrieval-augmented generation is a big plus
  • Advanced understanding of data structures and algorithms
  • Bachelor's degree in Computer Science or a related field is appreciated
  • You must speak German at level C1 or higher
  • You must speak English at level C1 or higher
  • You already live or are willing to relocate to Cologne, Germany

Benefits

We are an early-stage organisation that values speed of development without cutting corners on core product quality. We are in the game to build scalable and maintainable software and seek engineers, not just programmers, who push the edge of tech between language models and math and can translate complex data into simple, coherent computation flows. Everyone should have skin in the game why we offer both competitive salaries and equity packages. Ownership and authority in decision-making are not only possible but required. We love hard work and sports, so that benefit is also covered. Can't wait to chat!
