Architect and maintain scalable CI/CD and automation infrastructure.
Set technical direction and best practices for the team - code quality, testing, reproducibility, and secure, responsible use of development tooling.
Evaluate recent tools, models, and techniques for adoption and advise on architectural decisions.
Development & Deployment
Own the full lifecycle of the systems you build: design, implementation, testing, deployment, monitoring, and iteration.
Partner with the wider engineering team to translate business problems into well-scoped automation and engineering workflows.
Monitor production systems for performance, cost, and reliability; proactively identify and fix issues.
Hands-on development across the full stack with TypeScript, React, Next.js, Node.js, and backend systems.
Mentor team members, review designs and code, and raise the technical bar across the team.
Provide technical leadership on engineering practices and development tooling adoption.




Guide and coach other engineers through design reviews and code reviews.
Foster a culture of learning, experimentation, and continuous improvement.
Stay current with engineering and development tooling, and evaluate new technologies.
Willingness to learn new technologies, with a genuine passion for AI and automation.
Contribute to building products and platforms for Zenith's future growth.
Participate in architectural discussions and long-term planning.
What you bring
