Technical Support Engineer

Tucows has been working on the Internet since the days when people unironically called it the Information Superhighway.

Today, we’re the second-largest domain wholesaler in the world with tens of millions of domains under management (OpenSRS / Enom). We’re doing all kinds of interesting things, including running an MVNO cell phone service (Ting Mobile) and building true fiber to the premises networks in towns and cities across the US (Ting Internet). We offer individual and small business domains and integration with various popular platforms (Hover/Ascio).

We’re a team of over 600 people serving tens of millions of customers around the world. Our growth has been incredible, smart and measured (NASDAQ: TCX, TSX: TC). Our success is built on a solid technical and financial foundation.

About the opportunity

You love the Internet. Not just using the Internet but the Internet itself; net neutrality, the open Internet, and all that important stuff. You will help to craft, develop and maintain services and features using various technologies to help the business deliver features and products within the domain industry. We work in real-time on live systems… so it requires a steady hand and a cool head. You’ll be joining a team of highly skilled and experienced engineers.

What we do

Now, this is a bit complicated, so hang on:

We are a domain registrar. We register and update domains for our customers. We do this for hundreds of top level domains, TLDs like .COM. Each TLD has its own technical requirements, and these are constantly evolving. New TLDs are also appearing at a regular rate. The companies that run each TLD are called registries.

Your job is to configure and adapt systems to such changes and additions.

What you’ll be doing

You will be involved in configuring, scripting and programming our systems to interact with each registry, as well as controlling how each TLD is processed. You will be communicating with registries all over the globe.

Over time, you will become able to understand business requirements and translate them into technology.

Example tasks include setting up and maintaining functionality in the following areas:

  • TLDs
  • Products
  • Registry connections
  • Order workflows
  • Validation rules
  • Data reconciliation and migration projects

The job may include having an on-call duty, which you would be compensated for separately.

Your profile

First and foremost, you know how the internet and domains work, and you have experience in this area.

You also have a flair for technology.

You’re a quick learner. You have good communication skills and you are proficient in English. You are self-propelled and team-spirited.

You have knowledge of and experience with a good number of the following technologies:

  • XML
  • XSLT
  • EPP
  • JavaScript
  • Regular expressions
  • SQL
  • DNS
