What you'll do

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

What we're looking for

  • 5+ years of professional Node.js development in production environments
  • Expert-level understanding of asynchronous programming, event loops, streams, and the Node.js runtime
  • Deep experience with TypeScript in production codebases
  • 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
  • Missionary, not mercenary: takes ownership and cares about what they are building
  • Craftsperson under pressure: writes code that survives, understanding that in regulated industries code is reputation
  • Direct communicator: speaks up respectfully and clearly about technical decisions
  • Long-term commitment: not looking for contractors who jump between projects every few months

Nice to have

  • Salesforce development experience: Apex, Lightning Web Components (LWC), Visualforce, or Salesforce API integrations
  • 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

Benefits

Meaningful technical challenges: security, compliance, scale, and reliability at the intersection of Node.js and Salesforce

  • Competitive compensation commensurate with your experience and impact
  • Direct collaboration with the founding team and engineering leadership
  • A profitable, stable company with aggressive growth plans — no funding anxiety, no runway clock
  • The opportunity to work on enterprise-grade products used by some of the largest organizations in the world
