About the role

Key responsibilities & impact

High-performance backend services and APIs powering enterprise-grade SaaS applications
Scalable, secure Node.js micro services and integrations within the Salesforce ecosystem
Modern front-end experiences using Vue.js and TypeScript that serve demanding enterprise users
CI/CD pipeline tooling, automation frameworks, and developer productivity infrastructure
Real-time data processing and event-driven architectures handling sensitive enterprise data at scale

Requirements

What you’ll need

5+ years of professional Node.js development in production environments — not tutorials, not side projects, not bootcamp exercises. Real production systems serving real users at scale.
Expert-level understanding of asynchronous programming, event loops, streams, and the Node.js runtime. You should be able to explain backpressure, the differences between setImmediate and process.nextTick, and why unhandled promise rejections are dangerous — without Googling it.
Deep experience with TypeScript in production codebases. We write typed code, and we expect you to understand why.
Strong command of RESTful API design, authentication patterns (OAuth 2.0, JWT), and API security best practices for enterprise environments.
Proven experience with SQL and NoSQL databases, query optimization, data modeling, and understanding the performance implications of schema decisions at scale.
Proficiency with Git workflows, code review practices, automated testing (unit, integration, and end-to-end), and CI/CD pipelines.
Solid understanding of containerization (Docker), cloud services (AWS/GCP/Azure), and infrastructure-as-code principles.
Salesforce development experience: Apex, Lightning Web Components (LWC), Visualforce, or Salesforce API integrations. If you know both Node.js and Salesforce, you are a rare and extremely valuable candidate to us.
Experience building or contributing to Salesforce ISV (AppExchange) products.
Vue.js front-end development experience, particularly with Vue 3 Composition API and state management.
Experience working in B2B SaaS companies serving enterprise customers with strict compliance requirements (SOC 2, HIPAA, FedRAMP, GDPR).
Familiarity with DevOps/DevSecOps toolchains and practices in the Salesforce ecosystem.
