Job description

About Rethink First
Rethink First is a leading behavioral health technology company working to make mental wellness, education, and support accessible and scalable. Through our suite of cloud-based platforms - including RethinkEd, RethinkCare, and RethinkBH - we serve educators, employers, and providers with tools that deliver measurable, inclusive outcomes.
We're on a mission to make behavioral health more effective, equitable, and human - and we're looking for a creative visionary to help lead that charge.
Role Summary
We are seeking a Senior Database Developer with strong SQL expertise (PostgreSQL and/or T-SQL) to design, build, and optimize database logic supporting critical application workflows. This role is heavily focused on developing and tuning stored procedures, improving query performance, implementing scalable data access patterns, and managing ETL processes in Azure Data Factory and Microsoft Fabric.
This is a hands-on, individual contributor role ideal for someone who enjoys solving complex data problems, writing efficient SQL, and owning database-related features end-to-end. You will work closely with application engineers and partner with senior database leadership on architecture and performance initiatives.
Key Responsibilities
  • Design, develop, and maintain stored procedures, functions, and queries for application features
  • Build, monitor, and troubleshoot ETL/ELT pipelines in Azure Data Factory and Microsoft Fabric
  • Optimize existing SQL code for performance, scalability, and maintainability
  • Analyze execution plans and resolve performance bottlenecks (indexing, query design, data access patterns)
  • Collaborate with application developers to implement efficient database interactions
  • Translate business requirements into well-structured database solutions
  • Support schema design, data modeling, and database changes for new features
  • Monitor and troubleshoot production issues related to database and pipeline performance
  • Assist with database administration tasks (performance monitoring, deployments, basic maintenance)
  • Contribute to database standards, code quality, and best practices
  • Own database-related workstreams from design through deployment and validation
Required Qualifications
  • 4-7 years of experience working with PostgreSQL, and/or Microsoft SQL Server
  • Strong SQL development skills, including writing and optimizing complex stored procedures
  • Experience managing ETL/ELT processes in Azure Data Factory and Microsoft Fabric
  • Solid understanding of query execution plans, indexing strategies, joins, aggregations, and set-based operations
  • Experience diagnosing and resolving performance issues in production environments
  • Familiarity with Azure or other cloud-based database platforms
  • Experience working closely with application teams on database-backed features
  • Strong problem-solving skills and attention to detail
Preferred Qualifications
  • PostgreSQL development experience
  • Experience with Databricks (notebooks, jobs, or lakehouse patterns)
  • Experience with performance monitoring tools (e.g., Datadog, Azure Monitor)
  • Familiarity with CI/CD pipelines for database deployments
  • Exposure to high-availability and disaster recovery concepts
  • Experience working in structured, enterprise environments
  • Familiarity with tools such as SSMS, Azure Data Studio, DataGrip, or pgAdmin
What Success Looks Like
  • Stored procedures and queries are efficient, reliable, and scalable
  • ETL pipelines in ADF and Fabric run reliably and are maintained effectively
  • Application features backed by database logic perform well under load
  • Performance issues are identified and resolved proactively
  • Database changes are delivered cleanly and with minimal production risk
  • Engineering teams rely on you for strong SQL expertise and execution

Benefits:
  • Generous health, dental, & vision benefits package
  • Flexible paid time off
  • 11 paid company holidays
  • 401k + matching
  • Parental leave
  • Access to our award-winning RethinkCare platform supporting neurodiversity in the workplace through parental success, professional resilience, and personal wellbeing.
