We Are Hiring

DevOps + SysAdmin Engineer

The "infrastructure" engineer of the Freemius’ development team

Freemius is a startup that helps plugin, theme, and SaaS developers around the globe run their business and accept payments, manage subscriptions & software licensing, get user-data, offer trials and (much) more.

Hi, my name is Vova Feldman, and I’m the founder of Freemius. I started the company with the vision of enabling coders around the globe to make their livelihood from building, sustaining, and growing subscription-first software product businesses of their passion.

As a technical founder with more than 23 years of experience in software design, architecture, and development, I was and still responsible for leading the tech 6 years after (couldn’t have been possible without the help of my awesome team, of course!).

Even though our engineering team is still small (4 kick-ass developers 💪), with our rapid product development and fast execution, tasks get piled up in the review queue faster than I can process. I realize I become the product development bottleneck simply because I can’t allocate enough time for engineering. It’s time to take off some of the technical hats 🧢 that I’m wearing. I’m looking for an experienced DevOps engineer with solid SysAdmin experience to help us develop modern CI/CD pipelines to accelerate our dev2production capacity, work on various projects to increase the development’s team code consistency & efficiency, and to grow & monitor our storage and cloud infrastructure.

What You Will Be Doing

Immediate Projects

Here are several concrete projects that we want to execute asap:

  • Set up CI/CD Git pipelines (unit testing, code conventions, etc.)
  • Spin, configure, and set up a master-slave replica of our MySQL DB on an EC2 AWS server.
  • Optimize our two WordPress instances for performance (NitroPack/Server-Caching/App-Caching) as Google is going to incorporate page speed in their algorithm by May.

Long-term Projects

We also have two larger projects that are not as urgent but definitely essential for the long run:

  • Figure out a process/automation to efficiently get a localhost development DB for new team members, with a schema synced to production, and preferably obfuscated or fake dummy data. Potentially using something like ProxySQL to make it work.
  • Auto-generate API documentation from our codebase. This one is a complex project and we already did some design & planning work.

Ongoing Work

In the “background,” you’ll need to wear a SysAdmin hat to ensure our cloud-based infrastructure runs smoothly and scales. That involves things like:
