Software solutions and customer services along the wide-ranging product life cycle complete the portfolio. Siemens Mobility empowers its customers to understand their IoT data, generated from rail assets, allowing them to gain valuable insights and get more out of their systems. 

We are looking for a JavaScript Fullstack Developer (m/f/d) to join our Innovation Team! 


In this role, you will be responsible for: 
  • Engage in designing and developing user-friendly frontend interfaces using React.js, JavaScript and TypeScript.
  • Support backend development with Phyton, contributing to RESTful API with FastAPI.
  • Convert design prototypes into functional and responsive interfaces.
  • Deploy, monitor, and maintain applications on cloud platforms like AWS or Azure with guided support.
  • Work as part of an Agile team, participating in sprints, code reviews, and cross-team collaborations.
  • Stay curious and continuously improve your prompting skills to better apply generative AI tools for coding, debugging, and productivity enhancement.

We're looking for someone who has:
  • 4+ years of hands-on experience in React.js, creating reusable components and working on responsive designs, SPAs and SSR.
  • Authentication Knowledge (eg., OAuth 2.0 JWT).
  • Solid foundation in JavaScript/ES6+ and TypeScript.
  • Knowledge of user experience (UX) principles to understand design implementation.
  • Experience with Web build tools (eg., Vite, Webpack, Parcel, Rollup).
  • Some experience with AWS and/or Azure, such as deploying or handling services in the cloud.
  • Familiarity with database operations, specifically SQL and/or NoSQL databases, to handle and process data.
  • Experience with Agile methodologies, (e.g., working in sprint cycles with daily stand-ups and Jira/ticket management).
  • Proficiency in English, with good communication and teamwork skills.
  • Solid grasp of Figma or other UX/UI prototyping tools, understanding of CI/CD pipelines and deployment processes and familiarity with testing frameworks for both frontend and backend are nice to have skills.

What you can expect from us:

A flexible working model to promote a better work-life balance, a health insurance and access to our on-site medical center. 2 volunteering days a year and 4 additional bridge days per year. In addition, you’ll have access to exclusive discounts on Siemens and Bosch brands, and access to Siemens Learning Platforms that allow for internal online courses, as well as external platforms such as Coursera, Udemy, and LinkedIn Learning. 

If this sounds exciting to you, then send us your application – in English – and we will get back to you!
