Senior Database Administrator (Postgres/Oracle)

We are seeking a Senior Database Administrator II with strong expertise in Oracle and/or PostgreSQL as primary database platforms, and solid hands-on experience with at least one secondary database technology (MSSQL, MySQL, or MongoDB). This role sits within our global Database Engineering team and requires demonstrable experience managing and operating database workloads on AWS cloud infrastructure from a DBA perspective. 

In this role, you will design, build, and support highly available, scalable, and secure database platforms across Keyloop's global estate. You will focus on performance optimisation, automation, capacity planning, backup and recovery, and engineering initiatives that enhance reliability, security, and efficiency. You will work closely with application teams, DevOps, cloud, and infrastructure groups to deliver robust database solutions that underpin Keyloop's automotive technology platform. 

• Managed Database Services: Working with RDS for PostgreSQL, Oracle, or MSSQL — including parameter group tuning, maintenance windows, multi-AZ configuration, and read replicas from a DBA perspective. 

• Database Monitoring: Using CloudWatch to monitor database-specific metrics (CPU, IOPS, storage, connections, replication lag), setting up alarms, and integrating with observability platforms. 

• Database Security: IAM roles for database access and backup operations, KMS encryption for database storage and backups, and AWS Secrets Manager for database credential management. 

• Database Networking: Understanding of VPC, private subnets, and security groups as they relate to database connectivity and access control. 

• Cost Awareness: Understanding of AWS storage and compute costs relevant to database infrastructure including EBS, S3 tiering (Standard, IA, Glacier), and RDS pricing. 

AWS certification (e.g. AWS Certified Database Specialty) is desirable but not essential. 

Technical Skills: 

• Strong SQL and query optimisation skills across multiple database platforms. 

• Proficiency with both Windows and Linux environments. 

• Strong scripting skills in one or more of PowerShell, Bash, or Python for database task automation. 

• Familiarity with AWS CLI for database-related operations (backup management, S3 interactions, snapshot handling).
