• Ensure high availability and operational excellence, providing guidance on troubleshooting complex issues.
• Partner closely with engineers, product managers, and other key stakeholders to shape technical requirements, scope backend initiatives, and identify cross‑team dependencies.
• Advocate for platform health, engineering efficiency, and the right long‑term investments.
• Mentor engineers across levels, supporting career growth, onboarding, and technical skill development.

• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or related field.
• 10+ years of professional software engineering experience, with deep backend specialization.

• Demonstrated ability to architect and deliver critical production systems at scale.
• Proficiency in at least one modern backend language (e.g., Java, Kotlin, Go, Node.js, Python) and comfort with UI frameworks (React, Vue, or similar).
• Strong communication skills and ability to influence engineering decisions across teams.
• Travel may be required up to 10%, depending on business needs.
• Experience collaborating with globally distributed teams.
