Job summary

Stand Together in Arlington, VA is seeking a Senior Full-Stack Software Engineer with a front-end focus to own design implementation for our consumer-facing web apps. You will build a Next.js/React TypeScript monorepo, craft a reusable components library, and ensure performance, accessibility, and reliability across auth and API boundaries.

You will mentor engineers, collaborate with UX and backend teams, and drive CI/CD on AWS Amplify while contributing to back-end work as needed.

Qualifications

• Bachelor's or Master's degree in computer science, engineering, or a related field.
• 7+ years of full-stack software engineering experience with a clear front-end focus and a portfolio of production-grade work.
• Experience mentoring software engineers.
• Excellent collaboration, communication, and cross-functional partnership skills.
• Proficiency in JavaScript/TypeScript, Python, and PHP.
• Strong Node.js backend experience, preferably with NestJS.
• Experience designing and consuming APIs in distributed or microservices architectures.
• Hands-on experience with JWT/OIDC authentication, including Auth0 or equivalent, and passport-jwt/JWKS patterns.
• Proven experience with relational (SQL) and NoSQL databases — schema design, query optimization, multi-environment deployments, and operational MongoDB (replication, sharding, performance tuning).
• Experience with Docker and container orchestration on AWS ECS (task definitions, logging, ECR).
• Working knowledge of core AWS services: Amplify, API Gateway, ALB/NLB, S3, EFS, CloudWatch, X-Ray, IAM, and VPC.
• Experience building and maintaining automation within cloud-native environments using IaC frameworks (Terraform + Terragrunt).
• CI/CD experience with GitHub Actions and GitHub OIDC for secure AWS deployments.
• Observability and production operations experience: logs, metrics, alarms, distributed tracing, and production troubleshooting.
• Experience with security best practices, including IAM least-privilege, private S3 patterns, and secrets management.
• Testing and quality discipline across unit, integration, and e2e layers (Jest), with strong linting and formatting standards.
• Experience integrating headless CMS platforms with modern front-end frameworks.
• Enthusiasm to contribute to Stand Together's vision and principled approach to solving problems, and a commitment to stewarding our culture, which champions values including transformation and innovation, entrepreneurialism, humility, and respect.

Responsibilities

• Lead implementation of Next.js (App Router) features, including SSR, SSG, ISR, server components, and image optimization across our high-visibility web properties.
• Design, extend, and maintain a reusable component library and Storybook, serving as the team's authority on design system standards and front-end architecture.
• Integrate client applications with OpenAPI backends and secure authentication flows (JWT/OIDC), ensuring reliability and correctness across auth boundaries.
• Ensure accessibility, test coverage (unit, integration, and e2e), and high performance standards — with Lighthouse and Web Vitals.
• Own CI/CD builds, deployments, and environment configuration for AWS Amplify; collaborate on CDN caching and image transform pipelines.
• Troubleshoot production issues, instrument front-end monitoring, and maintain runbooks and on-call readiness for client-side reliability.
• Contribute to back-end tasks as needed, working closely with the broader engineering team across a Next.js/React TypeScript monorepo.
• Mentor engineers on front-end best practices, design system conventions, and performance engineering.
