The role

This is a full-time role as a Senior SRE with a focus on Kubernetes, infra, security & platforms, located onsite in New York, NY.

You will work directly with the founding team to turn infrastructure and security projects into new and significant revenue. Incumbents in our space are bloated, on outdated infrastructure and getting hacked. This presents an exciting opportunity for Hadrius to make a clean and fast break into mega-large firms like JP Morgan with security as a key differentiator.

We pride ourselves on our “hands off culture” by having very few meetings and giving engineers and creators a broad scope of responsibility and autonomy. You’ll be working in-person 5 days/week in our lower-manhattan NYC office, building side-by-side with the rest of the team. Our tech stack is django/python, react/next/typescript, running on Kubernetes (EKS) and Terraform on AWS.

What you need

About you

You’re hard working, ambitious and you prefer to “lead from the front”. As a leader on the team, folks will be looking to you as an example of success and you value being a role model and force multiplier for others on the team.
You’re looking for a fast growing startup. Here’s our revenue growth and head count growth.
You’re looking for teammates, not coworkers - folks you’ll be able to count on to in a pinch and make your team’s goals possible. Here’s a bonus picture of our CTO’s son closing his first sale.
