Core Responsibilities

  • Design and build internal tools, services, and automations across the full stack (frontend, backend, data layer)
  • Translate revenue and operations requirements into well-architected, maintainable software
  • Own features end to end — from technical design through deployment, monitoring, and iteration
  • Build and maintain integrations across our stack (HubSpot, Mixpanel, Aloware, Meta, Google, and others)
  • Design and implement API layers, webhooks, and data-sync services between systems
  • Diagnose and resolve API issues, sync failures, and attribution gaps at the source
  • Design data models and schemas that keep information clean, structured, and reliable across systems
  • Build data pipelines and validation logic to enforce integrity and prevent drift
  • Support reporting reliability with trustworthy, well-instrumented data flows
  • Build and maintain dashboards and reporting infrastructure for sales and marketing leadership
  • Instrument systems for real-time funnel monitoring and proactive issue detection
  • Ensure accuracy of key metrics (speed-to-lead, conversion rates, ROAS) at the data layer
  • Audit funnels end to end (ads → forms → CRM → sales activity) and fix breaks in lead flow and attribution
  • Proactively harden systems against failure as volume grows

Qualifications

  • 5–8+ years of professional full stack software development experience
  • Strong proficiency with modern languages and frameworks (e.g., JavaScript/TypeScript, Node.js, React, Python)
  • Deep experience building and consuming APIs (REST, webhooks, OAuth) and integrating third-party systems
  • Solid database and data-modeling skills (SQL, schema design); data warehousing experience a plus
  • Comfortable across the stack: backend services, frontend UI, and the data layer in between
  • Experience with cloud platforms (GCP or AWS) and serverless/scripting environments
  • Highly analytical, with strong attention to detail and a bias toward shipping
  • Bonus: experience with CRM platforms (HubSpot), product analytics (Mixpanel/Segment), AI/LLM integration, or revenue/marketing operations systems
