Senior Software Engineer Backend/Infrastructure

About SimplicityDX: SimplicityDX (SDX) converts creator user-generated content (UGC) into structured, verified, agent-readable social proof for AI-powered commerce. We operate as infrastructure for the agentic commerce era, not as a content or marketing tool. Our platform began by solving a real-time problem for the creator economy: as a creator’s post goes live, SDX ingests it, matches it against brand product catalogue and the creator’s own media, and assembles a purpose-built storefront on the fly. The creator gets a single link to drop into their social call-to-action, and that link resolves to a shoppable experience built for that exact post. We are now extending that same ingestion, verification, and assembly capability to a bigger problem: AI shopping agents (ChatGPT Shopping, Google AI Mode, Perplexity, Gemini, and the frameworks that will follow them) can already retrieve structured product data — price, specs, availability. What they cannot do reliably is judge whether a product actually works for a specific person or use case. SDX’s verified creator UGC is built to close that gap: human-validated evidence, creator context, and use-case-specific claims that an AI agent can reason over rather than merely retrieve. Our mission is to make verified, trustworthy UGC a standard, queryable layer of the agentic web — available not just on our own storefronts, but to any AI chatbot or agent that shops on a consumer’s behalf. Why Lisbon: Lisbon is our first office outside our current base, and this hire is one of the founding members of that team. Early engineers here will have an outsized hand in how the office’s engineering culture, standards, and working practices take shape. What You’ll Work On: SDX engineers work across a pipeline that runs from raw creator content to something an AI agent can trust and act on. Depending on the role, that includes: Real-time ingestion — pulling and normalizing creator content across heterogeneous, constantly- changing social pl
