Senior Fullstack Software Engineer, AI (Backend focused)

At Gorgias, we’re building the platform that makes this real: a unified AI agent that sells, supports, and re-engages customers across the entire journey. Conversational Commerce is the future of ecommerce, and we’re leading that shift.

Our mission is to turn every interaction between a brand and its customers into a relationship: personal, seamless, and intelligent. By combining deep product expertise with the latest in AI, we’re making shopping feel more natural, human, and connected than ever before.

To win, we focus relentlessly on:

• Develop end-to-end features across backend, APIs, and frontend

• Translate shopper event streams and product data into the context that LLMs can act on

• Own the multi-turn conversational behaviour of our AI Agent: quality, reliability, and iteration in production

• Build and improve evaluation workflows for prompts and agent behaviour

• Define practical ways to measure and improve AI performance in production

• Optimize for cost and latency as models and usage scale

• Evolve the platform as we scale it for higher load and more complex use cases

• Improve data ingestion, context building, and observability

• Partner with product and design to shape AI-driven user experiences

• Strong backend foundations and the ability to quickly pick up new languages. We work in Python and TypeScript, and we hire for problem-solving, not specific stacks

• Production experience integrating LLMs into user-facing products, including multi-turn or agentic systems

• Hands-on experience evaluating prompts and agent behaviour, formally or informally. You’ve had to answer “Is this getting better or worse?” in production

• Experience designing systems that turn structured data (events, user state, transactions) into LLM context

• Experience building and operating APIs and event-driven services

• Comfort with frontend work when needed (React), even if your centre of gravity is backend

• LLM observability tooling experience

• Experience optimizing inference cost or latency in production

• E-commerce, merchant-facing, or marketing-tech product experience

• Backend: Python and TypeScript

• Frontend: React

• Infrastructure: Event-driven services, Temporal workflows, APIs

• AI: LLMs, prompt engineering, multi-turn conversational systems, agent SDKs, evaluation

• Recruiter phone screen

• Hiring Manager interview

• System Design interview

• Live Coding interview

• Final interview

AI at Gorgias
At Gorgias, AI is a natural extension of how we work and build. Our teams use it every day to research, write, analyze, code, and craft better customer experiences. Everyone has access to premium AI tools (ChatGPT, Claude, Granola & others) and an annual L&D budget to explore new ones.

The real magic happens when we share what we learn. Our #powerup Slack channel is a digital petri dish of new tools and workflows, and each team has AI champions who showcase fresh ideas during weekly company-wide standups, now practically AI demo sessions.

We see AI not as a replacement for creativity or empathy, but as a multiplier, helping us move faster, think deeper, and serve customers better.
