Job description

Overview This is a hybrid role - 2 days remote and 3 days in the Malvern, PA office.

We are seeking a highly skilled Site Reliability & Cloud Systems Engineer to design, build, and operate scalable, secure, and highly automated cloud platforms in AWS. This role combines hands-on reliability engineering with cloud architecture and automation expertise, with a strong emphasis on building immutable infrastructure and improving system resilience. You will play a key role in evolving our AWS ecosystem into a “push-button” platform—reducing manual operations, embedding security into every layer, and ensuring production systems are observable, performant, and self-healing. This role is well-suited for a proactive engineer who excels at the intersection of infrastructure, automation, and system reliability, blending responsibilities across SRE, DevOps, and Cloud Engineering.

Who we are

At CubeSmart, we're intentional about culture. You can experience it everywhere from our mission statement of “genuine care” to our “It's What's Inside That Counts” tagline to calling each other “teammates” rather than employees. This spirit fosters a fun and collaborative environment that has resulted in our rapid growth and being recognized amongst the top in our industry.

CubeSmart's award-winning team is made up of people who genuinely care. Teammates care about our customers and the life events and/or business needs they are facing. Teammates are passionate, responsible and understanding.
