  • Experience with enterprise multi-tenant architectures
  • Familiarity with bit-set data structures (optional)
  • Observability/monitoring experience with Datadog and/or Elasticsearch
  • Familiarity with Cypress for automation testing
  • MarTech/SaaS background (audience segmentation, email marketing, subscription management)
  • Experience integrating AI/LLM capabilities into existing apps (e.g., MCP layer, agentic UI patterns)
  • Fluent English with 9am-5pm EST availability
  • Flexible schedule - ability to work extra hours for sprint deadlines

  • First Engineering Hire - Shape the technical foundation of a rapidly growing startup
  • Massive Market - Tech debt affects $3 trillion globally with 41% created by AI
  • Real Impact - Help companies save millions in development costs
  • Cutting-edge Tech - Latest AI/ML technologies solving real business problems
  • Growth Opportunity - Lead digital transformation in the modernization market

Benefits & Compensation
