Arcesium LLC's standard text

Company Overview

Arcesium is a global financial technology firm that solves complex data-driven challenges faced by some of the world’s most sophisticated financial institutions. We constantly innovate our platform and capabilities to meet tomorrow’s challenges, anticipate the risks our clients encounter, and design advanced solutions to help our clients achieve transformational business outcomes.

Financial technology is a high-growth industry as change and innovation continue to disrupt the status-quo and prompt major transformation. Arcesium is at a particularly interesting time in our own growth as we look to leverage our successfully established market position and expand operations in pursuit of strategic new business opportunities. We value intellectual curiosity, proactive ownership, and collaboration with colleagues, and we empower you to meaningfully contribute from day one and accelerate your professional development.

Position Summary

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.

What you will do:

  • Engineer our Linux compute platform based on Kubernetes and AWS
  • Engineer our Python and Terraform-based tools and automation
  • Build infrastructure applications, write, and review code as needed
  • Solve problems with a combination of coding and implementation of open source tools
  • Troubleshoot and debug complex systems
  • Leverage our design, coding, automation, and implementation skills to engineer what Arcesium needs, solving business and technology problems

What you’ll need:

  • We prefer 5+ years of relevant infrastructure experience. However, we are interested more in what you’ve done, can do, and can grow to do, rather than the number of years you’ve been working.
  • Proven track record of ownership of critical systems and delivery of systems and features. You have owned and operated critical infrastructure systems like Linux, Kubernetes, DNS, Kerberos, and/or AWS IAM.
  • Polyglot programming capability, with advanced level Python ability. Other languages in our ecosystem include Java, Go, and Bash.
  • Experience with running critical workloads on AWS
  • Ability to balance delivery with correctness, delivering timely solutions that are properly risk-managed for the needs of the business
  • You have an inquisitive mind, the ability to learn and problem-solve, and are a self-starter
  • A bachelor’s degree in computer science, computer engineering, or related discipline is required
  • Have a valid work permit to work in the country.
