Dublin, Dublin City, Ireland beBeeEngineer Full time
Transform Global Connectivity

Our vision is to build a world where seamless communication knows no borders.

As a key member of our team, you will have the opportunity to contribute to shaping this future. We are currently seeking passionate individuals who share our desire to transform the way people communicate.

At Telnyx, your code doesn't just run, it powers real-time connections across continents, emergency services, and businesses communicating with their customers in real-time.

We're a global communications infrastructure handling millions of calls and messages daily, and we need senior engineers who thrive on technical challenges that most companies never face.

The Impact You'll Drive

As a Senior Backend Engineer, you're not just writing code—you're solving problems that affect millions of users and shaping the future of communications technology.

You'll design systems that need to be fast, reliable, and scalable from day one, because downtime isn't an option when you're powering critical infrastructure.

You'll own big technical decisions. From API design to database architecture, your expertise will guide how we scale our platform to handle exponential growth.

You'll build across the entire stack. Debug production issues that span multiple services, collaborate with teams across the company, and see your solutions deployed to systems processing massive real-time traffic.

What We're Looking For

6+ years of backend engineering experience with functional programming languages (Elixir/Erlang strongly preferred)

Database expertise at scale - You understand how to design, optimize, and troubleshoot relational databases handling high-volume traffic

Distributed systems mastery - You know microservice patterns inside and out, including when to use them and when not to

Concurrency comfort - You've wrestled with the challenges of distributed programming and know how to build systems that stay consistent under pressure

Production mindset - You've debugged complex issues across multiple services and know what it takes to keep systems running smoothly

Bonus Points For

A strategic engineering approach - knowing when to move fast versus when to build for the long term

Product curiosity - you want to understand the business impact of your technical decisions

Knowledge sharing - you stay current with technology trends and enjoy teaching others

Why You'll Love Working Here

Autonomy that matters. You'll have real influence over technical decisions and the freedom to solve problems your way.

Scale that challenges. Our traffic patterns and reliability requirements will push your skills in ways most companies can't.

Impact you can see. Your work directly affects how millions of people communicate—from startup founders closing deals to families staying connected across the globe.

Growth without limits. Work with cutting-edge technology while solving problems that haven't been solved before. Every day brings new technical challenges that will expand your expertise.

Culture of Excellence

Join a team of senior engineers who care deeply about craft, collaboration, and building systems that stand the test of scale.
