Join the Data Transfer group within our Ingestion Department, a high-impact engineering team responsible for building and scaling the infrastructure that powers secure, reliable, and high-throughput data movement across our SaaS platform.

About The Role
We are seeking an experienced Lead Software Engineer to develop software and guide a team in applying engineering best practices to deliver high-quality, maintainable, and scalable systems.

This role serves as a technical liaison across teams, helping resolve dependencies, improve engineering processes, and proactively identify and mitigate risks to software delivery.

  • Drive post-incident improvements by leading root cause analysis and implementing fixes that prevent recurrence
  • Champion Infrastructure as Code and platform “paved roads” to improve consistency and developer experience
  • Guide engineers through design reviews and establish clear quality standards while unblocking cross-team dependencies
  • Collaborate with Product to make data-informed trade-offs across reliability, cost, and delivery speed
  • Influence stakeholders across teams by negotiating priorities, mediating conflicts, and managing expectations
  • Support team growth by contributing to development plans, delivering actionable feedback, and raising the hiring bar
  • Communicate effectively through architectural decision records (ADRs) and narratives that connect technical trade-offs to customer and business outcomes

Required
WHAT WE’RE LOOKING FOR

  • 7+ years of experience building distributed SaaS systems using .NET/C# or similar technologies, including 3+ years leading initiatives or teams
  • Deep expertise in Azure, including AKS, Service Bus/Event Hubs, and Cosmos DB or SQL, as well as multi-region patterns
  • Proven ownership of SLO/SLA outcomes, including on-call leadership and driving root cause analyses that eliminate repeat incidents
  • Strong experience with observability at scale, including OpenTelemetry tracing, metrics, logging, dashboards, and alert design
  • Experience with CI/CD practices, including GitHub Actions or similar tools, canary/blue-green deployments, feature flags, and automated rollback
