Role Description We're modernizing a large, business-critical fintech platform. Our current system is a mature Node.js/Express + MongoDB backend (with RabbitMQ workers, batch jobs, and a reports service) paired with a tri-generational frontend — layers of Backbone/Marionette, legacy React class components, and a React + Redux + Material-UI app all coexisting in one codebase. We're looking for someone with the judgment to tell good patterns from bad ones — who can recognize where the legacy system went wrong, avoid repeating those mistakes in new work, and design scalable solutions that still have to live alongside a rigid, established system. You'll contribute to new NestJS services and Next.js UI, write tests, and ship changes that respect the constraints around you — using AI tooling (Claude Code, Copilot) as a force multiplier, not a crutch. What you'll do - Work across the full stack — data model, API contract, UI, and production behavior — contributing to domains as they move onto the modern stack. - Recognize bad legacy patterns and don't repeat them — read the existing Express/MongoDB and Backbone/React layers, understand where they fell short, and apply better practices in new development rather than carrying old habits forward. - Design for scale within real constraints — build solutions that scale even when they have to integrate with a rigid legacy system that can't be changed wholesale. - Build on the modern stack — NestJS modules (DI, guards, interceptors) and Next.js apps (App Router, server components, typed clients). - Understand the strangler-fig approach — how legacy and new run side by side, behind feature flags, with zero data loss and no downtime — and contribute to it without disrupting it. - Model relational data carefully — help move money-bearing/transactional data from documents into a normalized SQL schema with real constraints and safe migrations. - Write tests as a default — unit, integration, E2E. The suite is what lets the team move fast safely. - Spot and flag problems — the flaky test, the N+1, the missing index. Raise them clearly so they get prioritized, and pick them up when it makes sense. - Use AI tooling efficiently while understanding and standing behind every line that lands. Qualifications - 4+ years shipping production full-stack - Strong TypeScript front and back · NestJS (or deep Express/Fastify w/ DI grasp) - Next.js/React (hooks, App Router, SSR/CSR) - PostgreSQL or MySQL (schema, indexing, transactions, migrations) - An eye for distinguishing good patterns from bad legacy ones - Ability to design scalable solutions that fit within an existing, rigid system - Testing discipline (Jest, Playwright/Cypress, Supertest) - API design (REST, auth, backward-compatible evolution) Bonus - Experience migrating off a legacy code - Fintech/payments/ledger - Message queues (RabbitMQ/SQS/Kafka) - MongoDB/Mongoose Aggregation - AWS/Docker/Kubernetes/CI - Deliberate AI-agent use in production workflows Who you are - Takes ownership and responsibility for their work - Eager to take initiative and grow - Has the judgment to spot bad legacy code and the discipline to not repeat it in new work - Designs for scale even inside rigid constraints - Refactors and builds with better practices rather than carrying old patterns forward - Moves carefully without breaking trust (tests + small PRs + flags) - Communicates trade-offs clearly - Raises issues and flags risks rather than routing around them Our stack - Today: Node · Express · MongoDB · RabbitMQ · React/Redux · Backbone · Material-UI · AWS · Jest - Going: NestJS · Next.js · TypeScript end-to-end · PostgreSQL/MySQL · full automated coverage Benefits - Excellent salary and benefits commensurate with experience Company Description ClassWallet is a positive, family-oriented team environment.
