About The Position

As a Senior Full-Stack Software Engineer (Front-End Focused) on our Enterprise IT team, you will own the design implementation for the consumer-facing web applications that serve as the front door to Stand Together's philanthropic community. You will build and maintain a Next.js/React TypeScript monorepo, implement production-grade UX and performance, integrate with our OpenAPI backend and headless CMS, and ship via CI/CD to AWS Amplify. The role combines deep front-end engineering, design-system ownership, and operational responsibility for client-side reliability and performance.

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.
