Job summary

Yuno is seeking a Senior Database Administrator to own the data layer powering our payment processing systems and the platform that provisions, deploys, and manages AI agents at scale on AWS. You will join the infrastructure team responsible for reliability, performance, and security of production systems, working with engineering and DevOps.

This role requires leadership in database architecture decisions, focusing on performance, scalability, high availability, and evolution of the data layer

Qualifications

• Bachelor's degree in Computer Science or a related field.
• 4+ years of hands-on experience as a Database Administrator in production environments.
• Deep PostgreSQL expertise – performance tuning, indexing, replication, and query optimization at scale.
• AWS – solid experience with RDS, EC2, VPC, IAM, and S3; understanding of networking fundamentals for database connectivity.
• CDC (Change Data Capture) integrations.
• Database security – access controls, encryption at rest and in transit, auditing, and compliance best practices for sensitive payment data.
• Terraform experience, with a preference for infrastructure reviewed in PRs rather than clicked in consoles.
• Python proficiency for automation and scripting.
• Proven backup/recovery and disaster recovery planning for critical systems.
• Distributed systems debugging – experience diagnosing data-related issues and cascading failures in production.
• English – advanced proficiency required.

Responsibilities

• Database administration and optimization — own maintenance, patching, and upgrades across our database fleet; lead performance tuning, indexing strategy, and query optimization for mission‑critical, high‑throughput systems.
• Reliability, backup, and recovery — design and own backup/recovery strategy, replication, and disaster recovery planning to guarantee stability and data integrity for payment processing workloads.
• Infrastructure as Code — automate database provisioning and maintenance with Terraform, working within the same IaC practices as the rest of the infrastructure team.
• Data migration and conversion — plan and execute complex data migration and conversion routines for production systems, verifying successful completion with minimal risk and downtime.
• Monitoring and performance — build the dashboards, alerts, and monitors that surface database health and performance issues before they become incidents.
• Technical leadership — mentor engineers on database best practices, provide expertise on deployment and architecture planning, and proactively communicate risks, issues, and next steps to the team.
