About the role

  • Designing, developing, and maintaining backend services that integrate with external e-commerce platforms (starting with **Shopify**).
  • Building and optimizing APIs that power installation, configuration, and data synchronization between Text and external systems.
  • Developing mechanisms for **sales tracking**, order history, and contextual data delivery across teams and products.
  • Collaborating closely with other product teams (AI Agents, Close Deals, Reporting, and Inbox) to ensure consistent, reliable data flows.
  • Contributing to backend architecture design and decisions, ensuring scalability, maintainability, and observability.
  • Researching and proposing technical solutions for new integrations or automation opportunities.
  • Taking ownership of your services end-to-end: from design and implementation to deployment, monitoring, and maintenance.
  • Working in a collaborative environment that values **knowledge sharing**, **proactivity**, and **technical ownership**.

Requirements

  • 6+ years of backend engineering experience, ideally in **product-focused SaaS environments**.
  • Strong experience with **Go (Golang) and/or TypeScript (Node.js) -** at least one is required, and experience in both is a plus.
  • Solid understanding of **distributed systems**, API design, and integrations with external platforms.
  • Experience working with **cloud platforms** (GCP preferred).
  • Knowledge of **SQL/NoSQL databases** (e.g., PostgreSQL, Redis).
  • Hands-on experience with **CI/CD pipelines**, containerization (Docker, Kubernetes), and observability tools.
  • Experience working in **data-driven environments** with event-based communication (Pub/Sub, webhooks, etc.).
  • Strong English communication skills, both written and spoken.
Benefits
  • You’ll build the systems that **power real e-commerce experiences** - from store connection to revenue tracking.
  • You’ll work closely with teams across the company (AI Agents, Reports, Inbox), impacting multiple products and customer journeys.
  • You’ll have **freedom to experiment**, research, and propose architectural improvements.
  • You’ll join a collaborative team that values asynchronous communication, clean documentation, and autonomy.
  • You’ll shape how e-commerce businesses interact with AI-driven tools - making their daily work smarter and faster.
