The Red Hat Cost Management team is establishing a new high-impact sub-team focused on delivering our service as a deployable on-premise product. We are seeking a highly experienced and strategic Principal Software Engineer to help lead the technical design and execution of this productization effort.
This role is critical for taking our existing SaaS codebase and re-architecting it for stable scalable deployment within a customers Red Hat OpenShift or Kubernetes cluster using Helm charts and Operators. A major architectural focus will be designing a highly performant resilient and manageable on-prem data model requiring deep expertise in PostgreSQL database architecture and performance tuning as we move away from distributed query engines like Trino.

You will act as the primary technical authority ensuring the successful launch adoption and long-term maintainability of this new product line.

What you will do

• As a Principal Software Engineer you will provide technical leadership and deep expertise in the following areas:
• Serve as the technical owner for the on-prem PostgreSQL data layer. You will design the database schemas indexing strategies partitioning and connection pooling to ensure high performance stability and ease of maintenance within customer clusters.
• Lead the architecture and implementation of the self-contained deployment mechanism to package deploy and manage the Cost Management application stack on-premise.
• Drive the necessary code modifications and refactoring of the existing Python/Django SaaS codebase to function effectively without reliance on distributed services (like Trino) and to meet the constraints of a self-managed environment.
• Champion and enforce a high level of code quality performance and security defining standards for the new on-prem product line.
• Architect the Continuous Integration/Continuous Deployment (CI/CD) pipelines specifically for building and validating the deployable assets (container images Helm charts Operator bundles).
• Act as a technical mentor and coach helping to build the foundational knowledge and technical direction for the new on-prem sub-team.
• Collaborate closely with Product Management and Field Engineering to define product capabilities and support models relevant to on-prem deployment.

What you will bring

• 5 years of experience with PostgreSQL including expert level database administration (DBA) or architecture focusing on performance tuning large-scale schema design indexing partitioning and connection management.
• 5 years of experience developing production-grade Python/Django applications using robust microservices and self-contained deployment patterns.
• 4 years of experience in Linux/Container administration with a focus on Kubernetes/OpenShift including building Helm charts and/or Kubernetes Operators.
• 3 years of experience designing integration patterns particularly adapting microservices for robust self-contained deployment.
• Extensive experience leading Agile workflows including expert-level Git branching strategies and release management.

Preferred Plus

• Direct experience contributing to or maintaining open-source Kubernetes Operators.
• Experience architecting the migration or replacing of distributed SQL query engines (e.g. Trino/Presto) with relational databases (e.g. PostgreSQL).
• Proven track record of building and maintaining enterprise grade CI/CD systems for productized software releases.
• Experience leveraging AI assisted tooling (e.g. Cursor Sourcery) to optimize code quality and team velocity.
