Senior Software Engineer

We're looking for a Senior Software Engineer to grow into full ownership of our engineering function. You'll work directly alongside our current engineering leader — learning the codebase, the systems, the integrations, and the team — until you can run everything independently. This is a genuine succession track: we want someone who can step into the seat at any moment, not eventually. Day to day you'll carry real ownership — architecture decisions, release authority, backend work, incident response — while building the institutional knowledge to be fully self-sufficient. No ramp period is permanent; readiness is the milestone. Key Responsibilities Senior Software Engineering Leadership Develop independent judgment on prioritization and architecture. Lead and coordinate backend engineers — assignments, sprint reviews, PR approvals, and technical mentorship. Share go/no-go authority for production deployments; make hotfix vs. queue calls jointly with QA. Build working knowledge of every product area: Glovebox, MPI, PromisePay, scheduler, OEM feeds, reporting. Hands-On Backend Work Stay active in the codebase — reviewing PRs, diagnosing production issues, and shipping fixes directly when needed. Own queue architecture work: the ongoing ActiveMQ → SQS migration, consumer management, and backlog triage. Monitor and respond to application-layer health via DataDog, CloudWatch, and AWS X-Ray. Identify and lead infrastructure cost-reduction initiatives (DocumentDB ReadIOPS, Lambda efficiency, etc.). DMS & OEM Integrations Become the internal expert on DMS integrations: Reynolds & Reynolds, CDK, DealerTrack, DealerBuilt, AutoSoft, AutoMate, Dominion, and more. Own engineering for OEM data pipelines — Toyota/Lexus TMNA feeds, Honda/Acura programs, Mazda, Ford GUDB, Hyundai/Genesis SLT, Kia, Audi/VW/BMW monthly reports. Provide technical guidance to Support and Customer Success on DMS-specific issues and integration edge cases. Incident Response & Escalation Serve as a primary escalation point for P0/P1 incidents — respond, contain, communicate, and document. Author RCAs following significant production events. Maintain runbook documentation in Confluence; keep escalation contacts current. Security & Compliance Own application-layer security: code-level vulnerability remediation, SAST findings, dependency management, and repo access. Serve as the engineering point of contact in SOC 2 and PCI-DSS audits. Coordinate with IT and SRE on cross-functional security policies.
