What the job involves

We are seeking a highly experienced Senior Staff Software Engineer or above to lead the design and implementation of scalable integration services for our Automation-Driven Open & Unified SecOps Platform

Our take

Cyber attacks and data breaches are on the rise, particularly at enterprise level, leading to a spike in demand for solutions that offer a 360-degree view of the security landscape – something that many security vendors aren’t able to provide, or at least specialize in.

In a bid to unify and optimize all the security tools used by enterprises, Stellar Cyber offers an open Extended Detection and Response (XDR) platform which integrates with existing stacks such as AWS, G Suite, Crowdstrike, and Cisco to automatically detect and nullify risks.

Though founded back in 2015, Stellar Cyber has been on an impressive upward trajectory since rebranding from Aella Data in 2019 and becoming more focused on medium-sized businesses with lean security teams.

The fact that it’s been continually expanding its leadership team and advisory board, receiving multiple awards year after year, and partnering with Amazon Web Services suggests that the company is intent on and is sustaining its rapid growth.
