• Strong concepts of custody key management, generation, HSMs and MPC technologies.
• Experience or awareness in working with Chainlink systems, services or ecosystem.
• Ability to script in a high-level scripting language like Python, Perl or bash coupled with an ability to identify human processes that can be scripted and automated.
• Deep familiarity with compute-infrastructure systems, tooling, observability, debugging strategies along with research aptitude and a desire to never repeat the same problem twice.
• Troubleshooting expertise of complex application flows which span multiple systems along with an ability to identify server, network, and application issues and apply measurable remediations.
• Working knowledge of Linux systems, system performance optimization and command line tooling.

• Strong written and verbal communication skills with an ability to distill information to both technical and non-technical audiences.
• Strong problem solving skills and ability to identify problems, determine their root cause, and see them through to solution.

Bonus Points: 

• At-least 5 years of software engineering experience.
• Experience with Kubernetes, or similar compute orchestration systems and a familiarity with container orchestration.
• Skill in defining infrastructure as code with Terraform or other infrastructure orchestration tooling.
