• Ensure systems are observable, reliable, and secure through thoughtful design and operational best practices

• Strong SQL skills and experience working with relational and analytical data systems
• Knowledge of Docker and container‑based deployments
• Ability to design, estimate, and deliver work collaboratively within an iterative development process
• Working knowledge of cloud infrastructure (AWS), Linux, and containerized environments
• Strong verbal and written English communication skills
• Proven ability to learn quickly, make pragmatic trade‑offs, and adapt to changing business needs
• Excellent collaboration and interpersonal skills
