Senior Full Stack Developer (React)

Senior Full-Stack Developer, Enterprise Applications

Job Locations: US | Remote

Although this is a remote position you will be required to interview one round onsite at a nearby location.

We are building an enterprise platform from the ground up — a custom-built system designed specifically for the automotive aftermarket wholesale business, with deep integrations into our ERP, analytics lakehouse, and AI services. This is not a COTS implementation or a Salesforce customization project.

We are seeking a highly skilled Senior Full-Stack Developer to join as one of the first engineers on the build team. You will have direct influence over technical decisions, code patterns, and system design. As the platform scales, this role grows into a technical lead position with responsibility for mentoring junior developers and guiding module development across the team.

This is a high-visibility project with direct stakeholder engagement at the executive level. Your work will be demonstrated to leadership regularly, and you will see the direct business impact of what you build — from a 75% reduction in customer onboarding time to AI-generated insights that drive millions in collection and sales activity.

Responsibilities

You will help design and deliver a modular enterprise platform consisting of integrated modules. Key areas of focus include:

• Shared Platform Core: Backend services powering authentication, RBAC, caching, event streaming, ERP integration, and a unified AI orchestration engine shared across all modules.
• AI-Powered Business Tools: Intelligent features including automated email generation, computer vision-based customer onboarding, demand forecasting, anomaly detection, and natural language querying.
• Operational Modules: Real-time dashboards, action queues, territory management, route optimization, lead pipelines, and executive scorecards used daily by collections teams, field sales reps, and senior leadership.
• Modern Frontend: A responsive React 19 + TypeScript SPA with a shared component library, module-based routing, and tablet-optimized design for field use.

Qualifications

5+ years of professional experience building production web applications, with at least 2 years at a senior level making architectural decisions.

• Full-Stack Proficiency. Production-level experience with both Python (FastAPI or Flask, SQLAlchemy or equivalent ORMs, async patterns, service-layer architecture) and React (hooks, context, component libraries, TypeScript, Tailwind or equivalent).
• AI/ML Integration Experience. Hands-on experience integrating LLM APIs into production applications — designing prompt chains, managing token budgets, implementing response caching, handling rate limits and fallbacks, and building user-facing AI features.
• Kafka and Event-Driven Architecture. Experience building or maintaining systems using Kafka for asynchronous event processing, change data capture, or inter-service communication.
• PostgreSQL + Redis. Experience designing relational schemas for multi-module applications, writing migrations, and using Redis as a caching layer with TTL strategies and invalidation patterns.
• Proficiency in JavaScript/TypeScript, including modern ES6+ syntax.

Technology Environment

You will be working within a modern, enterprise-grade technology stack that includes:

• Frontend: React 19, TypeScript, Tailwind CSS, Recharts/D3
• Backend & Cloud: Python 3.12, FastAPI, SQLAlchemy ORM, Pydantic
• Databases: PostgreSQL (multi-schema), Redis Cluster (6 nodes)
• Messaging: Apache Kafka (10+ topics, CDC patterns)
• Data Warehouse: Databricks SQL Warehouse, Delta Lake (medallion architecture), MLflow
• ERP Integration: IBM i AS400 via ODBC, Data Queue API, PCML, CDC via Kafka
• AI/ML: Anthropic Claude (text + vision), Google Gemini, Databricks MLflow
• Infrastructure: Kubernetes (Nutanix AHV), Docker, GitHub Actions CI/CD
• Monitoring: Grafana, Zabbix, TimescaleDB
• Security: Okta SSO, HashiCorp Vault, Arctic Wolf
• Version Control & Methodology: GitHub, Agile/Scrum
