Preferred * Fintech or lending experience - a plus, not a requirement. * Experience with schema-first / OpenAPI-driven development and typed API clients. * Experience with payment processing, loan origination, or loan servicing systems. * Zero-downtime migration discipline and on-call / runbook experience. * Familiarity with MLOps, ML engineering, or supporting the AI/data-science model lifecycle. * Understanding of data structures and distributed systems for large-scale data processing. ## Description This is a rare opportunity to build our agentic lending platform end-to-end - from the borrower-facing web app through the Django API and the fintech integrations that move money and make credit and loans work. This is a genuinely full-stack codebase, not frontend-with-a-BFF: most features touch both the app and the backend. You'll help set technical direction, own problems from ticket to production, raise the engineering bar as the team grows, and work closely with experienced leaders, a cross-functional team, and our vendor partners. You'll scale your impact through strategic decisions, reviews, and mentorship - while still shipping. It's an early leadership role with room to grow as the team does. The compensation for this role is pay + equity. Flexible New York City remote/hybrid. Full time. The stack you'll work in * Frontend: Next.js, React, TypeScript, TanStack React Query, Zustand, React Hook Form + Zod, and a shared component library built on Radix UI + MUI. * Backend: Django + Django REST Framework, Python, PostgreSQL, Celery, Redis. * Schema-first API: OpenAPI schema that generates a fully typed TypeScript client - types flow from Django serializers to React components, so schema drift is caught at compile time, not in production. * Infrastructure: AWS (Elastic Beanstalk and core services), GitHub Actions CI/CD. * Fintech integrations. What you'll own * Hands-on, full-stack feature delivery across the borrower app and the Django API - most features span both. * Fintech integration work: new vendor APIs, reliable webhook handling, retry and reconciliation semantics, and payment and loan-servicing workflows. * Infrastructure evolution - growing with scale. * Raising the engineering bar: testing strategy, observability, performance, and security in a regulated lending domain. ## Related Videos - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Inside Bitpanda's Tech Stack: Scaling a European Fintech Leader - Markus Dorner](https://www.wearedevelopers.com/videos/1979-inside-bitpanda-s-tech-stack-scaling-a-european-fintech-leader-markus-dorner) - [Accelerating Authentication Architecture: Taking Passwordless to the Next Level](https://www.wearedevelopers.com/videos/733-accelerating-authentication-architecture-taking-passwordless-to-the-next-level) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) - [Under the Hood of Building on Lovable](https://www.wearedevelopers.com/videos/100032-under-the-hood-of-building-on-lovable) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 7 Most Popular Backend Frameworks for Developers](https://www.wearedevelopers.com/magazine/403-the-7-most-popular-backend-frameworks-for-developers)
