Full-Stack Developer (AI-Assisted Development)

Stack

Responsibilities

• ▹Develop, optimize and maintain Next.js front-end applications with pixel-perfect UI and high performance across all 6 portals
• ▹Build and maintain NestJS APIs, microservices and scalable back-end architecture with Prisma ORM
• ▹Own Prisma migration workflows: schema changes, migration generation, seeding and coordination with QA on data integrity
• ▹Deploy and manage infrastructure on AWS and Google Cloud Platform (dual-cloud architecture)
• ▹Implement and maintain multi-tenant architectures with code-level tenant isolation, where each portal has distinct user roles and data access patterns
• ▹Use Claude Code as your primary AI-assisted coding tool to generate code, debug and refactor
• ▹Use Cursor as a secondary AI IDE for rapid iteration and code exploration
• ▹Orchestrate and configure sub-agents within Claude Code for complex multi-step tasks (test generation, documentation, migration scripts, code reviews)
• ▹Build MCP (Model Context Protocol) integrations connecting AI tooling with platform data sources and workflows
• ▹Write code that passes SonarCloud quality gates on first push (4,484+ issues being burned down in waves)
• ▹Address feedback from 5 PR review bots (Devin, Bugbot, Codex, Copilot, Augment) in addition to human reviewers
• ▹Work on front-end aspects including data extraction tools, dynamic scheduling, dynamic pricing and workflow automation interfaces
• ▹Optimize application performance for millions of concurrent users: efficient database queries, connection pooling, caching (Redis/ElastiCache), lazy loading and code splitting
• ▹Design and implement scalable data access patterns: pagination, cursor-based queries, read replicas and query optimization for high-throughput workloads
• ▹Build systems that handle tens of millions of sessions without degradation: connection management, rate limiting, graceful degradation and horizontal scaling
• ▹Profile and resolve performance bottlenecks across the full stack: frontend rendering, API response times, database query plans and cache hit ratios
• ▹Collaborate closely with designers, product managers and QA to deliver features rapidly
• ▹Contribute to the Marcia Enabled ecosystem by building AI-powered features across the platform

Requirements

• ▹Proven, daily experience using Claude Code (or an equivalent agentic coding tool) as your primary development environment, including prompt engineering for code, sub-agent orchestration, multi-file refactoring via AI and AI-driven test generation
• ▹Hands-on experience configuring and using sub-agents for parallelized tasks: writing tests, generating docs, running migrations and reviewing PRs via AI
• ▹Comfortable using Cursor as a secondary tool for code exploration, inline completions and rapid prototyping
• ▹Strong JavaScript/TypeScript and Next.js expertise (App Router, Server Components, Suspense)
• ▹Deep proficiency with NestJS for backend API development and microservices patterns, and with Prisma ORM (schema design, migrations, seeding)
• ▹Proven experience building and optimizing applications serving millions of users with high concurrency: database query optimization, connection pooling, caching, horizontal scaling and profiling bottlenecks
• ▹Experience identifying and reducing unnecessary cloud spend, optimizing database costs, right-sizing infrastructure and writing code that minimizes compute and memory use
• ▹Proficiency with AWS services (ECS, Lambda, S3, CloudFront, RDS, SQS) and Google Cloud Platform (GKE, Cloud Run, BigQuery, Cloud Functions)
• ▹Experience in multi-tenant front-end and back-end architecture with tenant isolation
• ▹Redis/ElastiCache for caching and session management (core infrastructure, not optional)
• ▹pnpm monorepo experience: the codebase is a monorepo with pnpm workspaces, used daily
• ▹SonarCloud compliance: understanding quality gates and code smell categories, and writing clean code that passes static analysis
• ▹Proficiency with CI/CD pipelines (GitLab CI, GitHub Actions) and deployment automation
• ▹Comfortable with remote development environments: developers work on EC2 dev boxes accessed via Tailscale VPN, not local machines, using SSH-based workflows
• ▹Experience with real-time features: Socket.io, Redis, BullMQ
• ▹Security hygiene: IP allowlists, secret scanning and push protection are enforced at the GitHub org level and pushing secrets triggers alerts; security consciousness is non-negotiable

Nice to have

• ▹Experience building or integrating MCP servers and tools
• ▹Background in LLM integration (API calls, prompt management, token optimization)
• ▹Exposure to serverless architecture and microservices integration on AWS/GCP
• ▹Experience in healthcare, veterinary or scheduling-heavy applications
