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)

- 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
