When applying for jobs, you should NEVER have to pay to apply. You should also NEVER have to pay to buy equipment which they then pay you back for later. Also never pay for trainings you have to do. Those are scams! NEVER PAY FOR ANYTHING! Posts that link to pages with "how to work online" are also scams. Don't use them or pay for them. Also always verify you're actually talking to the company in the job post and not an imposter. A good idea is to check the domain name for the site/email and see if it's the actual company's main domain name. Scams in remote work are rampant, be careful! Read more to avoid scams. When clicking on the button to apply above, you will leave Remote OK and go to the job application page for that company outside this site. Remote OK accepts no liability or responsibility as a consequence of any reliance upon information on there (external sites) or here.

This job post is closed and the position is probably filled. Please do not apply. Work for RDX Works and want to re-open this job? Use the edit link in the email when you posted the job!
What is the job?
As a DevOps Engineer at RDX Works, you will lovingly maintain our (your!) virtual infrastructure, while supporting the needs of our different stakeholders, which range from a collection of community node runners to developers and SDETs.
You will begin in familiar territory, performing care and feeding for dozens of virtual machines and Kubernetes clusters while gathering performance data and tuning for the CPU/memory/disk sweet spot which best balances performance and cost.
You’ll participate in the continuous improvement of our current monitoring and alerting system, so that we know when things are going awry and can take action.
After you have a handle on how to keep things running smoothly, as part of the DevOps team you will engage with members of the different developer teams and node runners, always devising best practises for running Radix nodes and other RDX applications on a variety of cloud platforms.
You will participate in our on-call rotation process, to ensure that someone from RDX is always available to investigate a disruption in service. You will respond to alerts and track them to resolution, while learning from incidents and feed suggestions back to our internal DevOps, SDET, and developer teams and improving our internal operational rulebook.
What are we looking for?
You have maintained production systems on virtual infrastructure, and you possess a healthy collection of war stories from past disasters.
You have a wealth of knowledge about Docker which you never get to use at parties.
You’re handy with an assortment of scripting languages, ideally Python or Bash.
You have a deep-seated need to automate things. The idea of doing a repeatable process manually is abhorrent to you.
You’re patient when dealing with others. You’re a good listener, and happy to be a teacher when needed.
You are a tenacious sleuth, able to persistently research and reason about difficult-to-reproduce problems until you have brought them to a satisfactory resolution.
What do you need?
Min 5 years experience in a DevOps role
Production experience with cloud providers such as AWS, GCP, and Azure (We use AWS)
Strong familiarity with Docker and Kubernetes
Familiar with agile processes
Experience working with observability tools such as Prometheus and Grafana Stack
Hands on experience with a scripting language
Comfortable with at least one infrastructure-as-code tool, such as Ansible and Terraform
Comfortable configuring and managing at least one popular Linux distribution.
Things That Will Really Help You Stand Out
Proven history of managing clustered/distributed environments
Proven history of node running at scale for any blockchain/distributed ledger
Have experience with Kubernetes
Chaos engineering is not alien to you
Who are we?
At RDX Works, we're a team of like-minded thinkers who have long been convinced that we're living in the earliest stages of a global financial revolution. This revolution is being fuelled by decentralized finance (or DeFi for short), which is enabling an assortment of pioneering developers and entrepreneurs to re-invent almost every financial product that is currently traded and invested in traditional markets, without requiring central authorities or siloed infrastructure. DeFi has captured a great deal of attention and investment in the crypto-aware niche, growing assets under management from $1 billion to $40 billion in less than a year. Impressive as its growth has been, its current market size isn't even a rounding error on the over $111 trillion held in traditional finance. We're focused on what it will take to go from billions to trillions.
RDX went back to first principles to come up with the right technical solution—the first layer-one protocol built specifically for mainstream DeFi—and we have already tested out at over 1 million transactions per second. We're keenly aware that the need for an infinitely scalable platform is only one prerequisite among many for mass adoption, and we're also blazing new ground in the areas of purpose-built developer tools, user experiences, and regulatory integration.
We have forged a path deep into the future of what distributed ledger technology is going to look like and we need you to come and be part of the team that is making that happen right now.

When applying for jobs, you should NEVER have to pay to apply. You should also NEVER have to pay to buy equipment which they then pay you back for later. Also never pay for trainings you have to do. Those are scams! NEVER PAY FOR ANYTHING! Posts that link to pages with "how to work online" are also scams. Don't use them or pay for them. Also always verify you're actually talking to the company in the job post and not an imposter. A good idea is to check the domain name for the site/email and see if it's the actual company's main domain name. Scams in remote work are rampant, be careful! Read more to avoid scams. When clicking on the button to apply above, you will leave Remote OK and go to the job application page for that company outside this site. Remote OK accepts no liability or responsibility as a consequence of any reliance upon information on there (external sites) or here.
