  • Responsibilities

    Our client has been building digital products for government agencies and businesses for over 20 years. The work is technical, the clients are high-visibility, and the team is small by design. Everyone here owns their work.

    This role is for a senior full-stack developer who is comfortable making technical decisions, working directly with clients and stakeholders, and mentoring the engineers around them. AI integration is a real part of this work, not a checkbox.

    What you'll do

    • Lead full-stack development across React, Next.js, Node.js, and TypeScript
    • Design and integrate RESTful APIs, GraphQL endpoints, and AI-assisted features including LLM-powered workflows and RAG
    • Work directly with clients to translate requirements into technical solutions
    • Make architectural decisions and hold accountability for them
    • Mentor junior engineers on modern JavaScript and AI-augmented development practices
    • Evaluate and adopt AI-assisted tools (Copilot, Claude, automated testing) where they actually improve the work
    • Contribute to CI/CD pipelines, cloud architecture, and DevOps practices

    What you bring

    Required:

    • 7+ years of software engineering experience, bachelor's degree or equivalent
    • 5+ years of professional JavaScript/TypeScript development, front-end and back-end
    • Strong React or Next.js experience building responsive, production-grade interfaces
    • Node.js proficiency with frameworks like Express or Fastify
    • Experience designing and consuming REST APIs and/or GraphQL
    • Solid understanding of relational or NoSQL databases (PostgreSQL, MongoDB, or similar)
    • Git and modern CI/CD workflows

    Preferred:

    • Prior government contracting experience
    • Cloud platform experience (AWS, Azure, or GCP)
    • Hands-on experience integrating LLM APIs (OpenAI, Anthropic, Azure AI) into production apps
    • Familiarity with RAG, prompt engineering, or agentic workflows
    • Docker, Terraform, GitHub Actions
    • Section 508 / WCAG accessibility standards
    • Agile methodologies

    Compensation Range is wide due to leveling (1 and 2).   Range depends on experience level.

    Level 1:  115-135k.

    Level 2:  135-170k.
