About Gelato

Gelato has created the world’s largest global network for on-demand production of custom products – from t-shirts and mugs to books and wall art. We empower a new generation of ecommerce entrepreneurs to share their creativity worldwide while embracing local, sustainable production. By producing locally and perfectly matching supply with demand, we eliminate waste and reduce carbon emissions.

At Gelato, we don’t own production facilities – we build the software that connects them. With over 140 production partners in 32 countries, our network can deliver custom products to five billion people in just 72 hours. It’s smarter, faster, and greener.

With GelatoConnect, our SaaS platform, we’re driving innovation in print production. GelatoConnect simplifies operations for print producers by automating procurement, workflows, and logistics into one seamless system. By boosting efficiency and cutting costs, it helps businesses scale to meet market demands. With GelatoConnect, we’re reshaping the print industry to be more efficient, sustainable, and profitable.

Gelato is an AI-first, cloud-native platform transforming local, on-demand production and delivery — with zero physical assets. We power:

• Global production orchestration: connecting e-commerce customers to 130+ partners across 32 countries. From AI-guided plate design to smart routing and logistics, we deliver to over 5billion people in under 72 hours—faster, greener, smarter.
• GelatoConnect: our AI-driven print production OS that helps producers master digital printing — from inventory to shipping — by automating every step: procurement, prepress, printing, packaging, and dispatch. It’s machine-agnostic, real-time, and built for uptime, precision, and profitability.

We are not just early adopters of AI — we’re AI-native builders. Across engineering, product, and operations, we embrace AI to accelerate innovation:

• AI-first development using LLMs for code generation, testing, documentation, and design exploration.
• Autonomous AI agents driving platform resilience, observability, cost control, and internal workflow automation.
• AI-native product features built into GelatoConnect and the core platform — improving routing, personalization, and production optimization.
• A culture of continuous experimentation with RAG, agent orchestration, prompt engineering, and model fine-tuning.

• Drive adoption of AI and agent-driven workflows to improve developer experience, automate operations, and prototype new capabilities.
• Build and evolve the Internal Developer Platform (IDP) to accelerate service delivery with reliability and scale.
• Develop internal tools, APIs, and automation that streamline developer workflows and enable self-service.
• Deliver and maintain CI/CD pipelines (Argo CD, Helm, CircleCI) and event-driven automation patterns.
• Enhance observability and feedback loops across build, deploy, and runtime stages.

• Strong backend engineering skills in Go; solid knowledge of clean architecture, DDD, and event-driven systems.
• Hands-on expertise with CI/CD, GitOps workflows, and platform automation.
• Familiar with platform foundations (Terraform, Helm, Kubernetes) and DevEx tooling (IDPs, service catalogs).
• Experience with identity and access management (Keycloak or similar).
• Knowledge of observability practices in cloud-native systems.
• Excited about AI-assisted development (Copilot, Claude, Cursor) and agent-based automation in engineering workflows.
• Curious, collaborative, and comfortable running PoCs to validate new ideas quickly.
