Terraform Developers Hiring Guide

Infrastructure as Code for consistent testing, staging, and production

Infrastructure as Code is one of the most talked-about subjects in enterprise IT these days. But what is IaC? Infrastructure as Code is the process of managing your infrastructure via code or scripts, rather than taking on this task manually.

IaC admins and developers use configuration files that are then distributed to systems on a network through a manager. By provisioning and configuring your systems this way, you ensure the process is not only repeatable but dependable and can even be automated. Once you’ve achieved an automated level of provisioning/configuration, your systems will run more reliably across the board.

With IaC it becomes possible to ensure all systems are always found at a specified state (such as always running the latest versions of various software). The IaC process generally includes the following steps:

  • Define and write specifications for systems, which are domain-specific.
  • Files are created and sent to the IaC management system.
  • The management system takes the steps to distribute the specifications to connected assets.

Typical benefits you’ll find with IaC include:

  • Cost reduction
  • Efficiency
  • Reduced risk
  • Improved testing
  • More stable and scalable environments
  • Accountability
  • Consistency
  • Better system documentation
  • Heightened system security

You’ll find numerous major companies that depend on IaC, companies like Uber, Udemy, Slack, Instacart, Robinhood, Twitch, Delivery Hero, LaunchDarkly, DISH, Freedom Financial, JPMorgan Chase, and Square, among others. 

That’s an impressive list, one your company would do well to be a part of. But how? What is your best route to employing Infrastructure as Code? 

In a word, Terraform.

What is Terraform?

Terraform is Hashicorp’s take on Infrastructure as Code that allows businesses to build, change, and version infrastructure securely and efficiently. With Terraform, you can more easily manage things like computing instances, storage, networking, DNS entries, and SaaS features. 

With Terraform, your admins/developers describe your infrastructure with a high-level configuration language, in human-readable declarative configuration files. These files serve as a blueprint for your infrastructure and can be versioned, shared, and reused.

It’s important to understand, however, that this solution uses a specific language for its’ configuration files. Terraform Language is used within Terraform CLI, Terraform Cloud, and Terraform Enterprise and is the primary user interface with the platform.

The syntax of the Terraform language shouldn’t be all that difficult for most developers and uses the following elements:

  • Blocks – containers for other content and usually represent the configuration of an object.
  • Arguments – assign values to a name.
  • Expressions – represent a value, either literal or referencing/combining other values. 

And because the Terraform language is declarative, most developers should be able to get up to speed quickly.

Typical use-cases for Terraform include:

  • Multi-tier application deployment/configuration
  • Self-service clusters
  • Software demonstrations
  • Disposable environments
  • Software-defined networking
  • Resource schedulers
  • Multi-cloud deployment

    Job Description

To hire Terraform users and managers, you'll need to set your sights on more than just developers and administrators. You need those familiar with DevOps, automation, provisioning, cloud-native, Terraform Language, and Infrastructure as Code. 

You'll also want to hire those who are familiar with your primary vendors, operating systems, and the various software stacks you deploy. Because there are so many moving parts to Infrastructure as Code, you need multi-talented team members who can immediately be thrown into the mix and not feel lost. 

Should you hire a team member who isn't familiar with the fundamentals of IaC, they will be way behind the curve. On the contrary, you might be safe hiring a new team member who has a solid understanding of IaC and other provisioning tools (such as Ansible and Puppet), who could then learn Terraform language fairly quickly. 

The important thing here is to make sure anyone you hire has a solid foundation of using management tools for the provisioning and configuration of company assets.


Most enterprise companies are already employing Infrastructure as Code. These tools have been around for some time and make the process of deploying and configuring infrastructure exponentially easier than doing it manually. If your business isn't already in the process of hiring an IaC team, you are behind the curve.
