Software Engineer IV/Tech Lead

AbsenceSoft provides secure technology that helps employers manage complex workplace leave experiences. The Software Engineer IV / Tech Lead will own core infrastructure for the enterprise leave management platform while leading technical initiatives, shaping architecture and roadmaps, mentoring engineers, and delivering production-quality code.

Responsibilities:

• 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

Requirements:

• Bachelor's degree in computer science, Engineering, or a related field — or equivalent experience — plus a track record leading complex technical initiatives
• Advanced proficiency in .NET/C#, building enterprise-grade software on a modern stack
• Hands-on experience implementing identity and authentication protocols (OAuth2, SAML 2.0, OIDC) in enterprise SaaS environments
• Proven ability designing multi-tenant SaaS architectures, including tenant isolation, data access patterns, and provisioning workflows
• Strong grasp of system architecture, scalability principles, and authorization frameworks (RBAC, data governance) in regulated environments
• Sharp problem-solving and debugging skills, with the independence to drive end-to-end solutions
• A natural technical leader and mentor who thrives on guiding direction and coordinating work across teams — not just executing to spec
• A clear communicator who can translate complex, systems-level thinking for technical and non-technical audiences alike
• Collaborative, adaptable, and results-driven, with genuine pride in the foundational platform work that powers everything else
• Curious about AI tools and concepts, and eager to put them to work
• 7-12 years of professional software engineering experience with SaaS platforms, distributed systems, and cloud infrastructure (AWS)
• Prior involvement in platform-scale initiatives, like framework migrations or multi-tenant redesigns
• DevOps fluency, including containerization and CI/CD pipelines
• Experience supporting compliance programs such as SOC2 or HIPAA
• Polyglot backend skills — Python and/or Node.js/JavaScript — NoSQL (MongoDB, CosmosDB) databases
• Familiarity with embedded analytics or BI tooling such as Sisense
• Experience with relational databases such as PostgreSQL or other ANSI SQL-compliant databases
