The Ultimate Guide to Hire a DevOps Engineer this 2022

In this post we will be taking a look at the techniques and tactics you can use to hire a DevOps engineer without breaking your budget.

We used to think senior software engineers were expensive, however these days hiring a DevOps is the most expensive hire in the IT world. Not only are DevOps engineers expensive, but they can also be quite hard to find in light of the massive demand and lack of education at universities in DevOps practices, deep Linux administration and Cloud practices.

Additionally, most college students tend to take the software engineer path instead of the DevOps engineer path. 

So, how can you find and hire a DevOps engineer in these complicated times? You’ve come to the right place! In this blog we will be guiding you on how to successfully hire a DevOps engineer.

Why Should you Hire DevOps Engineer?

Suppose you have a web application or digital product with multiple environments and services (back end and front-end). 

Are you interested in improving your web development productivity or scaling your web application?

Are you planning to distribute your system and services? 

If you answered yes to any of the above, you need a DevOps engineer with good skills in Automation, Infrastructure as Code ( IaC ), Continuous Integration and Continuous Delivery, Cloud Expertise, and a deep understanding of the Linux O.S (or windows / .net ecosystem). The DevOps engineer will also need other skills mentioned further in this article. 

What does a DevOps Engineer do?

As a former DevOps engineer, let me explain what it is exactly that we do. Before the appearance of the DevOps term, we had Network engineers, Security engineers, System administrators (Unix and Linux admins), and Automation engineers. These positions integrating Cloud and DevOps practices have evolved into a  single position: DevOps engineer. In a nutshell, a DevOps developer automates infrastructure tasks via IaC or bash/python scripting, therefore maintaining and configuring a cluster of servers. They also create and sustain CI-CD pipelines, secure servers, and cloud services.

Furthermore, DevOps are masters of Linux and know how to create highly distributed systems using the AWS cloud (or any cloud) with microservices, Kubernetes, Amazon ECS/Fargate, or just virtual on-premise servers. 

Most importantly, they are the gurus of cloud services. They know how to integrate any AWS managed service, including Amazon RDS, Aurora, Amazon S3, or even a cloud networking issue (VPC Networking). Also, if you have an intruder in your systems, a server hack, or a classic Jenkins/WordPress hack, they are usually the ones to investigate and inspect the root cause, find the vulnerability, and provide the analysis and remedy.

DevOps developers can also be in charge of Code release management and troubleshooting production deployments. They can also take on the tasks of a site reliability engineer, including maintaining servers, triaging server production issues, and attending to any server alert (they are usually on an on-call schedule). These sound like tasks for a DevOps engineer, right? Indeed, sometimes site reliability engineers do DevOps stuff, and vice versa.

Do you better understand now why it’s important to have a DevOps engineer within your organization? It’s common for bold software engineers or tech leaders to take on these responsibilities (DevOps tasks). Instead of randomly using your software engineer who was mostly trained in developing features, you should take your DevOps strategy to the next level and hire a DevOps engineer.

DevOps Engineer Principal Tasks and Responsibilities

Now that you understand how a DevOps engineer benefits an organization, let’s review their specific tasks. 

Continuous Integration and Continuous Delivery (CI/CD)

Create, design, and maintain Continuous Integration and Continuous Delivery pipeline in Jenkins, Gitlab, CircleCI, or AWS CodePipeline. A DevOps engineer can find ways to decrease the deployment time from hours to minutes! Do you need a deployment on the weekend? They can take care of this as well, as long as you schedule it in advance!

Automate and Script Repetitive Tasks

Bash and Python scripting automate your infrastructure, servers, containers, cronjobs, or any process that a DevOps engineer can codify.

Maintain and Deploy Infrastructure

DevOps can bring new production environments with Terraform or Cloudformation. Also, because of their good knowledge in Infrastructure as Code (IaC), they can maintain and deploy infrastructure through IaC tools.

Security and Hardening

DevOps can also handle security incidents including hacks, security audits, hardening of servers, and user security controls such as AWS accounts, SSH keys, Linux/Unix privileges, permissions, SSL certs, encryption, and API key encryption (Amazon KMS, for example).

Troubleshoot any Linux instance

Is DNS a problem? Server? Networking? Are emails not working? Probably an AWS DevOps Engineer can help. After all, he is the Linux guru. As a Windows or .net-based app, he should be good at maintaining Windows servers with similar responsibilities.

Cloud Networks Tasks

DevOps know how to interconnect different VPC networks, troubleshoot networking issues, deploy VPN services, and create virtual networks.

Dockerize Open Source Applications

The DevOps engineer creates microservices architectures for your enterprise SaaS application. Our blog on how to dockerize a Python/Flask app may be helpful.

Kubernetes Clustering

A DevOps developer can create a Kubernetes Cluster in production with Amazon EKS, Azure KS, or Google KS. We have created an article about creating a Kubernetes cluster on AWS that can help your DevOps engineer.

Security Compliance

Are you a Fintech health-care, or do you care about application security following PCI, HIPAA, ISO27001, or SOC2 regulations? Great! They can help you with all the technical qualifications from security compliance, creating a VPN, hardening containers, adopting DevSecOps, Vuln assessments, patching vulnerabilities, and disaster recovery strategies.

Back-end Development

DevOps engineers can work with Python, boto3, and AWS SDK for back-end and AWS development.

Application Troubleshooting

They can troubleshoot your web application, either Java, Node.js, Python, Go, or Laravel. Sometimes this falls more on the side of the Software engineer, but the DevOps engineer should be capable of understanding if it is a code issue or a DevOps issue and channeling it to the right tech team.

Maintain and Administer Database

The DevOps engineer is not the DBA expert per-se (SQL query expert) but has proficient knowledge to troubleshoot, create and build database clusters. Ex. Mysql, RDS replicas, PostgreSQL, MongoDB sharding, etc.

It is important to remember that a DevOps developer might not cover all these tasks. Usually, 50-70% of the above functions are suitable for a good senior AWS DevOps Engineer.

DevOps Engineer Roles

  • Most DevOps engineers are focused on DevOps practices. 
  • They can also be a Cloud engineer, which focuses on Cloud administration in one or two clouds including AWS, Azure, GCP, Digital Ocean, or on-premises.
  • Linux administrator is another role common to DevOps which concentrates on maintaining Linux servers, open-source services, and server troubleshooting.
  • DevOps engineers can also be focused on on-premise servers, which means they are concentrated on physical data centers and virtual environments (Vmware, Hyper-V, etc.).
  • Finally, DevOps can be site reliability engineers (SRE). A person in this type of DevOps role usually maintains Linux servers and increases the reliability of the production systems. This person is also responsible for responding to on-call incidents and conducting Root Cause Analysis (RCA) on previous incidents. Sounds like a DevOps role, right?

Good communication is a key skill for a DevOps seeing as they can be asked to work remotely. Virtual communication can be tricky and therefore the DevOps must have the ability to overcome any communication issues that may arise. 

When faced with a problem, a good DevOps should be able to quickly determine its cause and come up with options for how to solve it. The ability to listen and understand the needs of a team is crucial when it comes to clear and productive communication. 

Tools such as Slack, JIRA and Zoom can be helpful for remote collaboration.  

Teamwork

The ability to work in harmony with a team has numerous benefits. First off, it’s essential for the creation of a coherent product. 

A DevOps engineer needs to understand how the team works and be familiar with each member’s activities and skills. Collaborating in an understanding environment will result in  good workflow and efficient processes with respect to the project or product. It’s no secret that with the proper teamwork mindset, development productivity can increase significantly.

Adaptability

The DevOps field is always changing and evolving, therefore DevOps engineers need to be adaptable. Learning new things in order to grow expertise provides for flexible development which can positively contribute to any project or problem that needs solving. You can discover adaptability capacity when you hire a Devops engineer by analyzing their knowledge, courses and experience.

Leadership 

The soft skills mentioned above can help you identify DevOps engineers with good leadership skills. 

Developers face ongoing digital transformations and should therefore be able to identify problems and solve them, all while taking into account the team’s opinions with empathy and humility, as this is what allows for a productive work process. The right  leadership style depends on how team members respond to essential changes in operations, technology, roles, and mindsets.
