  • DevOps mentality with practical experience in CD/CI and following code through production operation and troubleshooting releases.

  • Track record of solving problems and delivering results in a fast-evolving environment.

  • Hands-on experience working in an AI-native development environment, proactively leveraging AI-assisted development tools as part of the software development lifecycle.

  • Familiarity with Spec-Driven Development, including the ability to work from clear technical specifications and translate requirements into production-ready implementations.

  • Strong ownership mindset and demonstrated ability to operate as a self-starter with limited day-to-day supervision.

  • Strong verbal and written communication skills and the ability to present complex ideas and influence stakeholders, with particular emphasis on clear, proactive asynchronous communication within distributed teams.

  • Ability to collaborate effectively with both technical and non-technical stakeholders.

  • Experience participating in sprint planning, technical design breakdowns, and scrum ceremonies.
