Backend Developer — Python

Backend Developer - Python

Engineering Zedelgem Full-time

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)(sic? we need correct closing )
• 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)

The details

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

Sound like your kind of gig?

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
