Mid/Senior Full Stack Engineer (Node.js, GraphQL, AWS)

We are looking for a strong, productive engineer to work directly with our Lead Engineer and CTO.

Your primary responsibility will be turning architectural specifications into production-ready features. The role is backend-focused, with significant responsibility for asynchronous processing and integrations, while also implementing frontend integrations in React / Next.js, including GraphQL queries, mutations, and UI components.

This is not an entry-level role. You are expected to be comfortable working with TypeScript, NestJS, and React / Next.js in production, within an AWS-based environment. The role spans the following technical areas:

Backend

• Node.js, TypeScript, NestJS
• Event-driven patterns
• GraphQL (Apollo Server) as BFF 
• PostgreSQL (MicroORM), Redis

Async & Messaging

• RabbitMQ
• Producers, consumers, retries, idempotency, message durability 

Frontend

• React, Next.js (App Router)
• GraphQL (Codegen, Apollo Client)
• Ant Design, SCSS Modules

Infrastructure

• AWS (EKS), Cloudflare
• Terraform
• gRPC (Protobuf)

What You’ll Do:

• Build backend features end-to-end: implement business logic, asynchronous workflows, and data synchronization.
• Design and implement GraphQL resolvers and schemas used directly by the frontend.
• Build and maintain integrations with external systems (CRMs, vendors, APIs), including authentication, retries, and failure handling.
• Implement frontend integrations in React / Next.js: write GraphQL queries and mutations and connect them to UI components.
• Provision and use infrastructure resources required by your features using Terraform (you don’t own infra, but you use it).
• Ensure production readiness: logging, tracing, and tests where they matter.

Requirements

• 4+ years of professional engineering experience.
• Strong hands-on experience with TypeScript and Node.js.
• Production experience with NestJS and GraphQL.
• Comfortable working with React / Next.js beyond basic UI changes.
• Experience integrating with third-party APIs, including OAuth and rate limiting.
• Practical understanding of AWS and ability to read and work with Terraform.
• Security-aware mindset when working with user data and identities.

Nice to Have

• Experience with Salesforce or other enterprise CRM APIs
• Experience working on projects with strict compliance requirements (e.g. HIPAA, SOC 2, ISO 27001).
• Interest in or experience with DevOps or information security

What We Offer

• Direct collaboration with the Lead Engineer and CTO.
• A greenfield system with no legacy constraints.
• High ownership and minimal process overhead.
• Fully remote work.
• High-end MacBook (M4 Pro) after the trial period.
• Relocation support to Australia after long-term collaboration.
