Job description

We are seeking an independent, client-facing Senior Full-Stack Developer (6–10 years of experience) to design, code, and deploy robust modules using the MERN stack, SQL, and AWS infrastructure.

Required:

  • Experience & Stack: 6 to 10 years of professional full-stack web development. Strong proficiency in the MERN stack (MongoDB, Express.js, React.js, Node.js) paired with relational SQL database design and complex query writing—a premium hybrid data talent pool.
  • Client Engagement & Communication: Excellent communication skills with explicit readiness to act as a technical resource when selling or presenting solutions directly to high-profile enterprise accounts like Marsh clients.
  • Cloud & DevOps: Practical knowledge of AWS cloud services (EC2, S3, Lambda, RDS) and collaborative Git workflows (branching, merging, pull requests).
  • Domain Context (Bonus Value): Prior insurance or claims knowledge, custom data analytics experience, and a track record with large-scale system migrations will heavily accelerate onboarding.
  • Professional Attributes: Deep understanding of software best practices (testing, debugging, documentation) with a proven ability to work independently and mentor junior team members.
  • Containerization & Automation: Docker, Kubernetes, and CI/CD pipelines.
  • Modern Languages: TypeScript and modern JavaScript frameworks.
  • Efficiency: Ability to leverage AI-driven tools to optimize programming workflows.

Duties:

  • Development & Data: Independently design, code, test, and debug technical modules using MERN and SQL. Handle custom data analytics and system migrations.
  • Deployment & Git: Deploy and maintain applications on AWS infrastructure. Manage source code repository hygiene using Git.
  • Client & Team Support: Provide escalated help desk support, monitor support trends to advise senior leadership, and serve as an enterprise technical resource.
  • Execution & Mentorship: Meet project milestones under limited guidance, follow rigorous security/testing standards, and actively mentor junior developers.
