Why you'll LOVE Sagent: You could work anywhere. We know you are talented and looking for something inspiring and impactful. A place where you will make a difference and have a great time doing it! By choosing Sagent, you can be part of our mission to make loans and homeownership simpler and safer for all US consumers. Sagent powers servicers and consumers. You power Sagent! About the Opportunity: We are seeking an Enterprise Architect to help lead the architecture change process governed by our Architecture Review Board (ARB). In this role you will evaluate proposed solutions across the full enterprise architecture landscape — Business, Data, Application, and Technology (BDAT) — assess them against our architecture principles, standards, and target-state roadmaps, and guide project and solution teams toward designs that are sound, secure, cost-effective, and strategically aligned. This is a breadth-first role with depth in at least one domain. You will spend less time building systems and more time shaping how systems fit together, why they should exist, and what the enterprise should stop doing. You will need to be equally credible talking about a value stream with a business VP and a network topology with an infrastructure engineer. Our environment includes on-premises data centers, mainframe workloads deployed to cloud, and a substantial Microsoft Azure footprint, so practical hybrid-enterprise experience matters. Your Day-to-Day at Sagent: Architecture Governance and the Review Board Co-lead the intake, triage, and review of architecture change requests entering the ARB, ensuring each submission has the artifacts, context, and analysis needed for an informed decision. Assess proposals against enterprise architecture principles, reference architectures, standards, and target-state roadmaps; identify risks, gaps, dependencies, and overlaps with existing capabilities. Facilitate ARB sessions: frame the decision, surface trade-offs, drive to a

Karya’s mission is to leverage the AI revolution to create dignified earning and learning opportunities for low-income communities across the world. In India, our smartphone-based digital work platform has enabled over 120,000 people to build language datasets and evaluate AI models while earning fair wages. With pilots in Kenya and Ethiopia and partnerships with leading AI labs, we are advancing language technologies for underrepresented communities. By combining dignified digital work with frontier AI innovation, Karya hopes to build a new AI economy that is equitable, inclusive, and community driven. About the Role Karya's PaaS vertical is the organization's global expansion arm, taking Karya's ethical data collection infrastructure to partners across Africa, Southeast Asia, and Latin America, deployed locally. This is one of Karya's largest bets: we're moving from a set of internally-run deployments toward a self-serve platform that partners can configure and operate themselves. We're looking for someone to be the first line of defence on that front: triaging and resolving partner-facing technical issues, coordinating with engineering when something needs a real fix, and critically - spotting the patterns behind repeat issues and scoping them as automation opportunities the platform team can build against. This role is explicitly built to evolve. As the platform gets more self-serve, the volume of manual triage should shrink and the expectation is that you grow with it, moving from first-line support toward solutions architecture: designing how partners configure and deploy the platform themselves, rather than fixing things alone. Key Responsibilities First-line technical support. Own initial triage for partner-facing technical issues — diagnose what's broken, resolve what you can directly, and route what you can't to engineering with enough context that it doesn't bounce back. Scope automation opportunities. Spot the pattern behind repeat iss
