Senior Python & React Full-Stack Engineer

Build what matters—stabilize, improve, and evolve a live product used every day.
Remote (EU) • Up to 5 remote days/week

As a Senior Python & React Full-Stack Engineer, you will be working for our client on an existing software product used within a single-client environment. Instead of starting from scratch, you will maintain, troubleshoot, and enhance a live solution—helping it grow as new users onboard and new needs emerge. If you enjoy practical problem-solving across frontend and backend, this is the kind of role where your work has immediate impact.

Your main responsibilities:

• Support the ongoing development and maintenance of an existing software product

• Troubleshoot and fix bugs reported by users during onboarding and day-to-day usage

• Implement improvements and new features based on user feedback and business needs

• Enhance the UI/UX experience to keep the platform intuitive and user-friendly

• Work across both backend and frontend layers of the application

• Collaborate with stakeholders to understand issues, prioritize enhancements, and deliver practical solutions

• Help onboard new users by ensuring the platform remains stable and effective

• Continuously improve code quality, usability, and performance

You're ideal for this role if you have:

• 6+ years of experience as a Full Stack Developer / Full Stack Engineer

• Hands-on backend experience with Python

• Solid frontend experience with React

• Basic to solid experience with databases and cloud-based environments (preferably Azure)

• A strong understanding of the software development lifecycle across frontend and backend

• Experience maintaining and improving existing products (not only building new systems)

• Strong debugging and issue-resolution skills with clean, practical fixes

• A product-minded approach with sensitivity to UI/UX and user needs

It is a strong plus if you have: (optional)

• Experience working on client-facing internal tools or single-client product environments
• Exposure to product support, user onboarding, or post-launch optimization
• Enthusiasm for AI and a practical understanding of how it works (without training models)
• Familiarity with Azure cloud-based application architecture

Language Required for the role :

• English (Fluent)

Eligibility for the role :

• Only candidates with an existing legal right to work in Europe will be considered for this role.
