Remote, Romania Holycode Full time

We at Holycode are currently looking for a passionate and experienced Backend Engineer to join Manukai, a "spin-off" from ETH Zurich developing an "AI copilot" to improve programming of metal machining (CNC) processes.

About the company:

Manukai is a Swiss technology company that develops data-driven software solutions focused on analytics, automation, and decision support. The company designs and builds scalable, production-grade systems that process complex data and translate it into actionable insights for operational and business use cases.

They take historical machining/programming data from a manufacturer (their past production runs, NC-code, machine parameters etc). Afterwards, they use algorithms to analyse and suggest optimal machining programs / process parameters for new parts (or variants) thereby reducing setup time and increasing efficiency. In the end, they integrate into existing workflows and tools (CAD/CAM, machine controllers) with minimal disruption — so manufacturers don't need to overhaul their system.

About the role:

This role supports Manukai's core product team in Zurich by developing and scaling their backend systems. You will work on well-scoped features and targeted bug fixes that improve the reliability, performance, and scalability of their platform. Collaborating closely with machine learning engineers and CAM integration engineers, you will extend Manukai's backend and implement clean, maintainable interfaces that connect product requirements with robust backend services.

Key Responsibilities:
  • Develop and maintain the backbone of Manukai's software stack
  • Implement, monitor, and maintain system integrations
  • Automate and optimize backend processes and workflows
  • Deep dive into complex problems to design and implement efficient solutions
  • Maintain high software quality and sustainable development practices; review code from other team members and provide feedback to ensure best practices (e.g. testability, efficiency, and style)
  • Document backend architecture, services, and integration processes
Your Profile:
  • Experience building backend services using Python, including application logic, data processing, and API development
  • Working knowledge of C# (.NET) and/or C++ for performance-critical components and integration with Windows-based systems
  • Extensive experience in Windows-based environments to create installers
  • Advanced skills with databases (especially with SQLite)
  • Understanding of how backend services support desktop applications, including collaboration with Electron-based frontend environments
  • Ability to work across language boundaries, integrating services and modules written in different technologies
  • Comfort collaborating with frontend engineers to design reliable, well-structured APIs
Nice to have:
  • Experience with manufacturing software (especially CNC machining) or engineering tools
  • Exposure to CAD/CAM or PLM systems
Why you will love working here:
  • Work on engineering and manufacturing software with real-world impact
  • Collaborate with experienced engineers in a product-focused environment
  • Familial working atmosphere in an open-minded multinational team
  • Working remotely (from Romania)
  • All necessary equipment – up to you to decide what you prefer
  • A budget for professional improvement (courses, conferences, books)
  • A budget for multi-benefits platform (meal tickets, private pension, etc.)
  • Premium private medical subscription with nationwide coverage
  • Budget for mastering English and German
  • Skilled and senior co-workers
  • Opportunities to build products that really make a difference
  • Opportunities to learn and grow with us
     
If you are looking for an environment where you can grow professionally, work on technically challenging problems, and build real-world AI products with impact, please submit your CV in English
