The Role:

We are looking for a Senior Fullstack Developer (Python/React.js) to join our fast-growing Network.

As a Full-Stack Developer, you will have a unique opportunity to join a team focused on solving the technology challenges in automating sales & procurement workflows, building material recommendation systems to match demand and supply, and developing internal and external user interfaces.

You’ll be passionate about product and user experience – customers are at the heart of what you do and that empathy drives your decision.

What we are looking for:

  • Strong experience in backend-heavy fullstack development using Python and JavaScript
  • Hands-on experience with FastAPI and React.js
  • Proficiency in building REST APIs and designing performant database models
  • Strong understanding of system architecture and microservices design
  • Experience with Kubernetes platforms, Docker, Git, and CI/CD pipelines
  • Familiarity with cloud platforms, especially GCP (preferred), and tools like AWS Lambda or GCP Functions
  • Knowledge of identity providers such as Auth0 or Okta and OpenID Connect
  • Familiarity with agile methodologies such as Scrum
  • High coding standards, including Design Patterns, TDD, and Clean Code principles
  • Strong analytical and debugging skills
  • Excellent communication skills and proficiency in English
  • (Nice to have) Experience in MLOps
  • Located in CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones.

Responsibilities:

  • Implement end-to-end automations in sales and procurement processes
  • Develop robust backend services and occasional frontend components using modern frameworks
  • Design and build scalable data processing pipelines and microservices
  • Contribute to system architecture and design from scratch
  • Write maintainable and reusable production-grade code and participate in code reviews
  • Collaborate in software design discussions and translate user requirements into valuable product features
  • Work closely with a cross-disciplinary agile team with shared responsibility and autonomy
