Job Description & How to Apply Below

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 Type Script
  • 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 Dev Ops practices
What you bring

Required:

  • 7+ years of software engineering experience, bachelor's degree or equivalent
  • 5+ years of professional JavaScript/Type Script 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 No

    SQL 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, Git Hub 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.

Clearance requirement

Must be a U.S. citizen or legal resident. This role requires the ability to obtain a Public Trust clearance.
