Full-stack Development Contractor
United States July 14, 2026

Job description

We're looking for a Senior Fullstack Engineer to join a technology company that's transforming the moving, storage, and last-mile delivery industry. In this role, you'll help build scalable products that power real-world logistics, collaborating with a team that values ownership, pragmatic problem-solving, and clean engineering practices. We're looking for a backend-leaning engineer who thrives in Node.js, enjoys designing APIs and data models, and is comfortable jumping into React, Angular, or React Native whenever the product requires it.

Key Responsibilities

  • Translate architectural and business requirements into actionable technical tasks, owning feature delivery end-to-end through to production deployment.
  • Build resilient, well-tested core services in Node.js, with deep ownership over the APIs and workflows that power supply, scheduling, and fulfillment.
  • Architect MongoDB schemas for complex workflows and continuously optimize performance through indexing, aggregation pipelines, and tuning at scale.
  • Build and maintain integrations with third-party services including payments, mapping/routing, SMS/notifications, and CRM platforms.
  • Contribute to frontend features in React, React Native, and Angular when work requires full-stack ownership.
  • Participate in technical design reviews, help set backend architecture standards, and leverage AI-assisted development tools throughout the engineering lifecycle.

Core Requirements

  • 7+ years of professional software engineering experience, with the majority spent on backend systems using Node.js in production.
  • Experience designing and versioning REST or GraphQL APIs consumed by multiple clients.
  • Solid MongoDB experience: schema design, indexing, aggregation pipelines, and performance tuning at scale.
  • Proficiency with frontend development using Angular, React, and React Native.
  • Working knowledge of GCP (Cloud Run, GKE, Pub/Sub, or similar) sufficient to understand deployments and debug production issues.
  • Direct experience building or scaling a two-sided marketplace, supply/demand matching engine, or fulfillment platform.
  • Familiarity with event-driven or queue-based architectures (e.g., Pub/Sub).
  • AI-forward mindset with active use of AI-assisted development tools (e.g., Claude Code, Cursor, Copilot) to accelerate delivery.
  • Excellent written and verbal communication skills in English.
  • Ability to work independently in a remote, fast-paced environment.

Additional

  • US Timezone Overlap: CST, Full overlap
  • Startup or fast-growing company experience with a track record of balancing speed and long-term maintainability.
