Sr Software Engineer - CPE

Job Summary

This role owns the software Credit Production Engineering runs on. It delivers complete solutions across all phases of the SDLC for CPE's internal platforms - the knowledge base, the services behind it, and the automation the team depends on during live triage - and is accountable for those codebases as products: design, code review, tests, deployment and ongoing upkeep. It operates with little day-to-day supervision, guides engineers writing automation alongside their operational work, and applies technical best practices to build-versus-configure decisions within its own area.

Essential Responsibilities

• Delivers complete solutions spanning all phases of the Software Development Lifecycle (SDLC) (design, implementation, testing, delivery and operations), based on definitions from more senior roles.
• Advises immediate management on project-level issues
• Guides junior engineers
• Operates with little day-to-day supervision, making technical decisions based on knowledge of internal conventions and industry best practices
• Applies knowledge of technical best practices in making decisions

Minimum Qualifications

• 3+ years relevant experience and a Bachelor's degree OR Any equivalent combination of education and experience.

Responsibilities

• Deliver complete solutions across all phases of the SDLC for CPE's internal platforms, based on priorities set with the CPE manager.
• Own CPE's tooling codebases as products - apply and uphold code review, testing and release practices for them, and be the named owner accountable for their state.
• Carry the knowledge base platform from pre-production to production: monitoring, backup and restore, documented ownership, and the operational layer a service needs once a team depends on it daily.
• Design, build and operate new services that reduce the team's toil on repetitive and manual work, including correlating operational signals that today are handled individually.
• Own the PostgreSQL schema and data layer behind CPE's retrieval platform - schema design, migrations, roles and grants, indexing and query performance.
• Advise CPE management on project-level technical issues, including build-versus-configure and sequencing decisions.
• Review code from, and provide technical guidance to, engineers who write automation alongside their operational work.
• Partner with engineering teams outside CPE to obtain the service topology and dependency knowledge CPE's tooling depends on.

Additional Qualifications

• Demonstrated ownership of a production codebase - not only writing code, but accountability for its design, review, tests, deployment and upkeep over time.
• Working fluency in both Shell scripting, Python and TypeScript. Most of CPE's tooling are Shell scripts and Python; the MCP is in TypeScript.
• Depth in databases: schema design, migrations, roles and grants, indexing and query performance, and running a database in production including backup and restore.
• Production experience with cloud infrastructure - AWS and GCP are both in play - including deployment and observability.
• Operational credibility with on-call engineers: prior time on a rotation, and an understanding of the work from the inside. This role is not in the on-call rotation, but is the escalation path for the services it owns.
• Ability to drive a technical design across teams where the role holds no authority.
• Comfort with ambiguity - much of this work has no precedent inside the team.

Preferred Qualifications

• PostgreSQL + pgvector or another vector store - embeddings, similarity search, index tuning.
• Retrieval systems or LLM tooling.
• Managed Postgres at scale - Cloud SQL, RDS, Aurora.
• Alerting and monitoring platforms - Datadog, Splunk, PagerDuty.
• Event correlation, anomaly detection, or time-series analysis.
