Job Description:

Arcesium seeks an accomplished Lead Infrastructure Engineer to join our Infrastructure team. All Infrastructure Engineers are coders and technology generalists who bring their unique combination of breadth and depth of experience and knowledge to the team. As a Lead Infrastructure Engineer, you’re passionate about providing the foundation and capabilities to our application developers to build upon, and love to solve problems with creative multi-discipline, polyglot, and/or open-source solutions. You are able to work independently, demonstrating “high agency” in your work, but you’ll balance your independence with leveraging the team and working with outside stakeholders as needed.

Job Responsibility:

Own the distributed systems ecosystem that powers our SaaS API-driven business
Construct innovative infrastructure systems, applications, and tools that streamline and enhance how Arcesium’s applications interoperate
Take ownership of our critical technology infrastructure
Provide highly available, reliable critical services to our customer-facing applications and developers

Requirements:

5+ years of relevant infrastructure experience
Demonstrated desire to take ownership of critical systems and successfully deliver systems and features
Advanced proficiency in Python and an eagerness to work with languages like Java, Go, and Bash as needed
Advanced knowledge and demonstrated experience with HTTP and other network protocols, load balancing, ALBs, nginx, Apache httpd, Kubernetes ingress, Kerberos, SAML, and other SSO technologies, authentication, and authorization
Ability to craft reliable and performant solutions to problems using a combination of software you write and open-source technology
Display a curious mind, enthusiasm for technology infrastructure, a knack for problem-solving, and the drive to take initiative and work with the right combination of independence and collaboration
A bachelor’s degree in computer science, computer engineering or a related discipline is required

Nice to have:

Proven track record of managing and operating vital polyglot infrastructure systems is a desirable plus
Experience in running critical workloads in AWS is a definite plus
