Frontend Developer React

ParaPy is growing its development team and looking for a junior, medior, and senior frontend developer (3 positions!), for whom React holds little secrets and who enjoys working with modern web-technologies such as Three.js / WebGL, Typescript and Redux. Come join our passionate team of developers dedicated to drastically accelerate engineering design and give engineers more time to explore, optimize and innovate! 


At ParaPy we believe that the future engineer creates smart software applications that automate routine work, freeing up time to explore more design ideas, optimize and innovate. We are developing a software platform that enables engineers to create, integrate and deploy such applications without needing a degree in Computer Science. Engineers use our signature Knowledge-Based Engineering language to capture design intent and various automation toolboxes to accelerate time-consuming human-computer interactions like 3D modelling, simulation, and pre- / post-processing thereof. ParaPy is used nowadays to radically accelerate design processes for a vast range of products like aircraft, ships, offshore structures, factories and buildings. 

What you’ll work on 

You will develop functionality that empowers engineers to create advanced (3D) web applications in Python without demanding in-depth knowledge of HTML, JavaScript and CSS. Moreover, you will create low-code solutions to speed up application development and a cloud-based environment in which engineers collaborate while executing engineering processes. Most of these technologies are either from-scratch or in an early prototyping phase, allowing you to pioneer and “shape” the future. Together with our project leads, you will have the chance to closely interact with some of our strategical customers (leaders in their respective industries) to identify requirements and convert these into new actionable features.  

What’s in it for you 

  • Work in a highly talented team and in an open learning environment 
  • Energizing atmosphere of YES!Delft; Europe’s leading tech incubator  
  • Time and budget for personal development and freedom to try out new technologies on the platform 
  • A good salary and the opportunity to grow with the company 
  • Engage with leading customers in a variety of industries such as GKN Fokker (aerospace), Aker Solutions (energy) and Royal HaskoningDHV (AEC) 

You will ideally 

  • Have professional experience in React, JavaScript and TypeScript. We are growing our team with 3 developers and are looking for the following levels of experience: 
  • junior:  1+ year 
  • medior: 3+ years 
  • senior:  5+ years 
  • Have a BSc in Computer Science or equivalent 
  • Enjoy writing clean and maintainable code
