About LearnWiseLearnWise AI is an AI-first scale-up building virtual assistants, instructor efficiency tools, and student engagement solutions for universities and colleges. We're a small team moving fast: the best idea wins no matter who says it, and every hire owns real scope from day one.

About the role
We are hiring a senior backend engineer who builds new features that extend our products and owns the hard platform problems behind them: integrations with systems we don't control, authentication and authorization in a multi-tenant product, and services that run in five regions. You design the solution, write it down, ship it safely, and stay with it in production. This is a backend role close to AI product surfaces, not an AI/ML research role.

What you'll do
Build new product features
• Extend our existing products with new capabilities, from design and data model to API and production rollout, together with Product and Design. Integrate institutional systems
• LMS, CRM (e.g. Microsoft Dynamics) and SIS data through a reusable integration framework, including writeback. Evolve the multi-tenant platform
• Organization hierarchies, granular role-based permissions, shared organization-level resources, and safe customization inside the LMS. Scale efficiently across regions and peaks
• Keep data and monitoring in-region across EU, US, CA, AU and UK, prepare for 10x term-start traffic spikes, and cut infrastructure and AI costs. Lead new initiatives




• Occasionally take technical leadership of a new initiative, coordinating the work of 2-3 engineers. What you bring
• 6+ years as a software engineer building and running production backend services.
• Production experience in more than one backend language (e.g., Python, PHP, Go, Java, TypeScript/Node, C#).
• Working Python knowledge and interest in learning async Python.
• Hands-on system integrations: third-party APIs, OAuth flows, webhooks, data sync, retries, and rate limits.
• Production ownership: logs, metrics, tracing, alerts; you debug live issues across services and third parties.
• Clear, direct written and spoken English; you raise blockers early.
• Daily use of AI coding tools, e.g., Codex or Claude, and you verify what they produce.
• Architecture design of services, data models, and service boundaries that others built on.
• Technical leadership: led development of a system across at least 2-3 engineers. Nice to have
• Our stack: Python, FastAPI, MongoDB, AWS, Docker, GitHub Actions.
• LMS integrations: LTI 1.3, Canvas, Brightspace, Blackboard, Moodle.
• Data residency and multi-region systems (GDPR, FERPA).
• Laravel/PHP experience.
• Exposure to LLM-powered products, agents, or tool-calling.
• Authentication and authorization in practice: SSO, OAuth/OIDC, JWTs, RBAC, multi-tenant access control.
