Senior Node.js Developer / Backend Architect

What You'll Own

• Architecture & technical direction of the entire serverless backend (Google Cloud Functions on Firebase / GCP).
• Code quality and standards — review PRs, define patterns, and guide the team on TypeScript best practices.
• System reliability — performance, observability, error handling, and deployment safety across dev / pre-prod / production environments.
• Integration strategy — design and maintain reliable two-way data flows with NetSuite, Business Central, HubSpot, Mailchimp, Constant Contact, Stripe, HERE API, Zapier, and Integration.app.
• Data architecture across Firestore (primary operational DB) and MongoDB (data warehouse).
• CI/CD pipelines in GitHub Actions, including selective function deployment.

• Mentorship — grow the engineering team and raise the bar on code review, testing, and documentation.
  
  What We're Looking For

  Must have:

• 8+ years of backend development with Node.js and TypeScript in production environments.
• Strong experience with serverless architectures — ideally Google Cloud Functions, AWS Lambda, or equivalent.
• Hands-on experience with NoSQL databases (Firestore, MongoDB, DynamoDB, or similar).
• Proven track record designing and maintaining third-party integrations (ERP, CRM, payment processors, webhooks).
• Solid understanding of event-driven architecture (Pub/Sub, queues, scheduled jobs, triggers).
• Experience designing REST APIs, request validation, authentication, and authorization patterns.
• Comfort owning CI/CD pipelines and managing multi-environment deployments.

• Ability to communicate clearly with non-technical stakeholders — including project managers, founders, and customers.

   

   

  Nice to have:

• Experience with Firebase ecosystem (Firestore, Cloud Functions, Auth, Storage).
• Background in CRM, ERP, or field operations domains.
• Familiarity with Stripe billing, subscription lifecycles, and in-app purchase reconciliation.
• Experience with geospatial features (route optimization, geofencing, HERE / Google Maps).

• Prior role as a tech lead or backend architect for an SMB / mid-market SaaS product.

• Real business impact — your work directly affects how field sales teams operate every day.
• Modern stack — TypeScript, serverless, cleanly structured codebase.
• Stable product with active enterprise customers and a clear product roadmap.
• Remote-first team and flexible schedule.
