Software Engineer IV / Tech Lead

The Software Engineer IV / Tech Lead is a hands-on technical leader who owns the core infrastructure that powers AbsenceSoft's enterprise leave management platform. This is a formal tech lead role, not a senior IC position with a title attached — you'll be expected to mentor engineers, drive architecture, and shape technical planning, in addition to writing production-quality code yourself. You'll lead through technical excellence, architectural influence, and mentorship, partnering closely with Engineering and Product leadership to balance platform investment against product priorities and drive the long-term health of the platform

What You’ll Do

-
Lead major technical initiatives — set direction, make key decisions, and coordinate engineering efforts across teams

-
Architect and build enterprise identity systems , implementing OAuth2, SAML 2.0, and OIDC, and defining authorization models like RBAC and data access governance

-
Own multi-tenant architecture , designing data isolation and provisioning workflows that make customer onboarding seamless and scalable

-
Ship complex features and platform components using .NET/C# on AWS, applying enterprise-grade engineering practices along the way

-
Strengthen data infrastructure by improving processing pipelines for reliability, observability, and performance, and by resolving complex production issues before they become bigger problems

-
Shape the roadmap by partnering with Engineering and Product leadership to balance platform investment against feature delivery, and by evaluating new technologies worth adopting

-
Raise the bar for the team through code and design reviews, mentorship across multiple teams, and continuous improvement via refactoring, automation, and tooling

-
Help uphold security and compliance standards across your area of the platform
