Backend Developer – Python

Build things that actually matter. At a company that actually cares.

At TelSmart we’re flipping sales and customer service on its head — modern voice tech, AI-powered communication tools, and zero tolerance for clunky experiences. We’re a tight team shipping real product for real businesses, and we’re looking for a sharp Python backend developer to come build with us.

If you love clean code, scalable systems, and the feeling of pushing something to production that customers rely on — keep reading.

What you’ll be building 🛠️

  • Designing and evolving the services that power voice, provisioning, integrations, and AI-driven customer communication
  • Writing Python that’s a pleasure to read and a beast in production
  • Working closely with product and frontend to turn good ideas into well-shipped features
  • Contributing to architecture decisions — scalability, reliability, clear trade-offs
  • Raising the quality bar: testing, observability, performance thinking

What we’re looking for 🧠

  • 5+ years of solid backend development experience
  • Strong Python skills — you understand the language deeply enough to direct it, review it, and own it
  • Fluent with AI-assisted development tools like Cursor, GitHub Copilot, or similar — you use them to move fast and stay sharp, not as a crutch
  • Real ownership in production systems (you’ve been paged, you’ve fixed it, you’ve learned from it)
  • Hands-on experience with AWS and cloud-native patterns
  • A product mindset — you care about outcomes, not just implementations

Bonus points ✨

  • Experience with distributed systems, event-driven architectures, or high-volume APIs
  • Familiarity with telecom or VoIP concepts (cool to have, not a dealbreaker)

Why TelSmart? 🚀

  • Your code ships to real customers — backend quality visibly impacts the product
  • You’ll work with experienced people across product, frontend, and platform
  • We care about craft and humans — no burnout culture, no hero mentality
  • Clarity, ownership, and trust are the actual foundation here

The details 📍

  • Belgium-based (min. 3 days onsite in Zedelgem HQ)
  • Full-time
  • Competitive comp, discussed transparently
