Backend Architect (Node.js) – Monolith Slayer & System Builder

Salary €6,500 - €10,000
Equity To be negotiated

Node.js Developer – Backend Rewrite 🚀


TL;DR: We’re moving from a Python3/Flask monolith to a modular Node.js architecture. You’ll start by stabilizing the current system (bug fixes, tweaks, the works) to understand its ins and outs. Then, you’ll help design and implement the next-gen Node.js backend as the foundation for the global mobile plan of the future.


Why this will be fun 🔥

  • No Legacy Chains: You’re not patching someone else’s mess forever. After you decode the current backend, you’ll lead the transition to a clean, modern Node.js architecture. You’ll be part of the full design and implementation process—your code, your blueprint.

  • Real Impact: At Telgea, every line of code has a purpose. We’re not building another “me-too” app. We’re reimagining global mobile connectivity, and you’ll play a key role in that.

  • Ownership, Not Overhead: Forget bureaucracy. If you have ideas for how we work smarter, better, or faster, they’ll actually get implemented.

  • Scalable Challenges: Build a system that handles real users, real data, and real complexity. Not just another CRUD app.


What You’ll Do 🛠️

  • Tame the Current Beast: Fix bugs, improve performance, and keep our Python3/Flask backend running smoothly while you get to know it.

  • Lead the Rewrite: Work with the tech lead to design and build a modern, service-based Node.js backend.

  • QA Champion: Take ownership of platform quality. Squash bugs, prevent new ones, and keep customers happy.

  • Modular Magic: Refactor core functionalities into clean, scalable services and APIs.

  • Team Play: Collaborate with frontend developers (our Next.js crew) and designers to keep everything in sync.


What You Bring to the table 🍽️

  • Strong backend development experience with a focus on Node.js.

  • Strong knowledge of RESTful APIs, backend architecture, and modular systems.

  • Proficiency in JavaScript/TypeScript.

  • Debugging skills to spot and fix problems (bonus points if you like QA).

  • Familiarity with SQL/NoSQL databases.

  • Cloud (AWS/Azure) and containerization (Docker/K8s) experience is a plus.

  • Willingness to work with our Python/Flask system. No Python mastery required, just curiosity.


Why Being a Developer at Telgea is Exciting 🚀

At Telgea, you’re not just another cog in the machine. You get to:

  • Ship Real Things: Your work directly impacts a product that simplifies mobile connectivity across borders. Customers will use what you build.

  • Work with Purpose: No throwaway tasks. You’re solving challenges that scale and matter. Transitioning systems, improving architecture, and building for real growth.

  • Enjoy Autonomy & Flexibility: We trust you to take ownership and get the job done.

  • Work with the best: We are very picky on who we bring onboard. We want to keep the team lean by only hiring few but exceptional people.

  • Shape the Future: We’re new but we’re scaling fast, and we’re solving tough global problems for millions of companies. You won’t just build a backend. You’ll help shape the entire platform and the way we scale it.


The company:

We’re a team of 10 exceptional people across product, sales, and operations. Since our launch in May 2024, we’ve launched mobile carriers (MVNOs) in 6 countries. Achieving what no one has done this fast before. By the end of the year, we’ll cover all of Europe, the US, and Canada, providing thousands of users with seamless local mobile service wherever they choose to live and work.


Oh, and the backend you build? It’ll live on as the gold standard we can all brag about.
