Frontend Engineer - 3D / Engineering Software - Manukai team

We at Holycode are currently looking for a passionate and experienced Frontend 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 extending and maintaining their frontend. You will work on well-scoped tasks and targeted bug fixes that directly improve product development speed and reliability. In close collaboration with their frontend engineers and UX designer, you will translate Figma designs into clean, scalable, and maintainable frontend code that integrates seamlessly into their product.

Key Responsibilities:

• Develop and maintain the frontend layer of Manukai’s software stack
• Implement and evolve user-facing features based on product and UX requirements
• Translate Figma designs into responsive, scalable, and maintainable frontend components
• Automate and optimize frontend workflows and processes where appropriate
• Deep dive into issues to identify root causes and implement efficient, high-quality solutions
• Maintain high software quality and sustainable development practices; review code from other team members and provide feedback to ensure best practices (e.g. maintainability, performance, accessibility, and style)
• Document frontend architecture, components, and development patterns

Your Profile:

• Solid experience building modern user interfaces with React and TypeScript, building scalable, maintainable, component-driven user interfaces
• Comfort using Tailwind CSS to build responsive, consistent UI layouts
• Ability to collaborate with designers using Figma, translating designs into clean, usable interfaces
• Solid experience with geometric or 3D modeling libraries (e.g. OpenCascade.js, WebGL)
• Working knowledge of Three.js and React Three Fiber (R3F) for interactive or visual-rich web experiences or willingness to learn them
• Experience packaging web applications as desktop apps using Electron or willingness to learn
• Experience integrating frontend applications with backend APIs, ideally from Python-based services

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
• Solve challenging UI and 3D visualization problems
• 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
