[Hiring] Senior Database Administrator @Apptegy

Role Description

We're looking for a Senior Database Administrator (DBA) to lead the reliability, performance, security, and scalability of Apptegy's database infrastructure. As a key member of our Infrastructure and Platform Engineering team, you'll own the health of our production databases and help shape the future of our data architecture as we continue to scale.

This role is ideal for someone who thrives in a cloud-first environment, enjoys solving complex performance and availability challenges, and is passionate about building resilient systems that support mission-critical applications. You'll partner closely with Engineering, DevOps, Security, and Product teams to ensure our data platforms remain secure, performant, and highly available.

Beyond our transactional databases, you'll also help operate and optimize our Snowflake data warehouse, which powers analytics and reporting across the company—balancing performance, cost, and data governance as our data volumes grow.

What You'll Do

• Administer, maintain, and optimize production databases hosted in AWS.
• Manage and support PostgreSQL, MySQL, and other relational database systems.
• Own the database layer of Apptegy's self-service internal developer platform.
• Design, implement, and maintain high-availability and disaster recovery solutions.
• Monitor database performance, identify bottlenecks, and proactively implement improvements.
• Analyze and optimize complex queries, indexes, and database configurations.
• Develop and automate operational processes for provisioning, maintenance, monitoring, and recovery.
• Partner with software engineers to optimize database access patterns, improve query performance, and support application scalability.
• Review and advise on schema design, database migrations, and application data access strategies to ensure long-term performance and reliability.
• Manage database backup strategies and regularly validate recovery procedures.
• Implement and maintain database security controls, encryption standards, and access management practices.
• Participate in incident response, root cause analysis, and post-incident improvements.
• Contribute to infrastructure architecture decisions and long-term scalability planning.
• Create and maintain operational documentation, runbooks, and best practices.
• Administer and optimize our Snowflake data warehouse, including virtual warehouse sizing, resource monitors, role-based access control, and query and cost performance tuning.

Qualifications

• 7+ years of experience administering production database environments.
• 3+ years of experience managing databases in AWS.
• Strong expertise in PostgreSQL administration, tuning, and optimization.
• Experience with Amazon RDS, Aurora, and other AWS database services.
• Hands-on experience administering a cloud data warehouse, ideally Snowflake.
• Deep understanding of database performance tuning, replication, backup and recovery, and high-availability architectures.
• Experience implementing disaster recovery and business continuity strategies.
• Strong knowledge of Linux systems administration.
• Experience with scripting and automation using Python, Bash, or similar languages.
• Experience supporting databases that power modern SaaS applications.
• Understanding of application-layer database interactions, including ORM-generated SQL and query optimization principles.
• Ability to design and build internal tooling and automation that leverages AI/LLMs, such as self-service database assistants, query-optimization helpers, or runbook automation that strengthen the developer platform.
• Familiarity with monitoring, observability, and alerting tools.
• Strong troubleshooting skills with the ability to diagnose issues across application, infrastructure, and database layers.
• Excellent communication skills and the ability to collaborate effectively across distributed teams.
• Professional proficiency in English.

• SnowPro certification, or advanced Snowflake experience with features such as data sharing, dynamic data masking, or ingestion tooling (e.g., Snowpipe / OpenFlow).
• AWS certifications, such as AWS Certified Database Specialty or Solutions Architect.
• Experience leading database modernization, migration, or cloud transformation initiatives.
• Passion for automation and reducing operational toil.
• A proactive mindset focused on continuous improvement and operational excellence.
