Senior Software Engineer - Full Stack

ICON INTERNATIONAL GROUP is seeking a Senior Software Engineer to lead the design and development of highly available distributed systems on AWS. The role sets technical direction, promotes automation-first engineering, and partners with product and client stakeholders to deliver resilient, well-tested systems.

Responsibilities:

• We are looking for a Senior Software Engineer to lead design and development of complex, highly available, distributed systems on AWS using Go, Python, and Node.js, running on Kubernetes-based platforms such as EKS and OpenShift
• You will set technical direction for a team, drive an automation-first engineering culture, and act as a hands-on technical leader who partners with product and client stakeholders to turn requirements into resilient, well-tested systems

Requirements:

• Bachelor's or Master's degree in Computer Science, Engineering, or a related field
• 10–12 years of software engineering experience, with significant depth in distributed systems
• 8+ years of work experience with Node.js
• 8+ years of work experience with Python (Programming Language)
• Experience with healthcare interoperability standards (HL7, FHIR, X12 EDI)
• Expert-level proficiency in Go and Python, with strong working proficiency in Node.js for polyglot service environments
• Deep hands-on expertise with AWS architecture and services, including container orchestration on EKS
• Hands-on experience running and operating workloads on Red Hat OpenShift as an enterprise Kubernetes platform
• Proven experience designing and scaling automation frameworks and infrastructure-as-code (Terraform, CloudFormation, or Ansible)
• Strong grasp of distributed systems fundamentals: consistency models, fault tolerance, service mesh, messaging systems (Kafka, SQS/SNS), and data partitioning
• Experience leading technical projects or small teams
• Strong written and verbal communication skills for working with cross-functional and client stakeholders
• Strong, demonstrated use of AI-assisted and agentic development workflows (Claude Code, Copilot, Cursor, or similar) across the full development lifecycle: design, coding, testing, review, and documentation
• Able to define and enforce team-level standards for responsible AI-assisted coding, including validation rigor, security scanning of AI-generated code, and avoiding data leakage in prompts
• Practical knowledge of AI/LLM integration patterns for backend systems: APIs, prompt design, retrieval-augmented generation (RAG), embeddings, and agentic workflows (e.g., MCP)
• Able to identify where AI-driven automation can meaningfully improve engineering velocity, code quality, or operational efficiency, and lead adoption within the team
• Extensive experience in the US health insurance or payer domain: claims, enrollment, benefits, provider networks, and HIPAA/compliance-aware system design
• Prior experience in a client-facing consulting or professional services environment
