  • Partner with product engineering teams to drive security outcomes - such as automation for patching, and development of gateways and other services to decrease risk
  • Mentor and help grow other Software Engineers in the team

Requirements

  • Bachelor’s degree in Computer Science, Information Security, or a related field
  • 8+ years of experience as a Software Engineer
  • Experience with production code bases
  • Experience with at least one scripting language (e.g. Python) and one systems programming language (eg. Golang, C/C++)
  • Experience with modern cloud infrastructure, including data pipelines, serverless workloads, and Kubernetes
  • Proven experience working autonomously on projects - delivering them to a high quality and on time
  • Excellent communication and interpersonal skills, with the ability to work effectively with both technical and non-technical stakeholders
  • Ability to dive deep to find the best solution to a problem
  • Obsessive curiosity and a willingness to ask questions, gather context, and learn
