Jose is an exceptional fit: he's a founding engineer with proven 0→1 AI product expertise, deep production experience shipping LLM agents and real-time AI systems at scale, and strong Python/FastAPI backend skills. He demonstrates the exact bias for shipping and high-autonomy ownership the role demands, having architected complex agent systems, made build-vs-buy decisions, and owned infrastructure/product simultaneously. The main gap is explicit UK location requirement and limited mention of multi-tenant SaaS architecture, though his work at scale with Twilio and Mycelium suggests capability here.
Hook: You've built LLM agents in production across multiple channels and owned the entire intelligence stack—this role is that scope with the autonomy you've already operated with at early-stage companies.
Missing: UK-based location (currently CA-based), explicit multi-tenant SaaS architecture experience

Hi, Your posting describes owning the intelligence layer end to end, working close to the infrastructure, and setting the engineering bar. That's exactly what I've been doing. At Addie I'm the founding and only engineer. I built a LangGraph agent system delivering counseling across web, SMS, voice, and WhatsApp, real-time voice on WebRTC + OpenAI Realtime API at sub-200ms latency, and three Next.js products on top. I owned architecture, build-vs-buy across voice/transcription/model providers, cost-per-conversation targets, and on-call. That's well beyond demos: thousands of concurrent sessions, students in 10+ countries, 99.9% reliability. Strong Python (FastAPI), and I've shipped multi-tenant systems in Docker/Kubernetes before. The high-autonomy, no-layers setup partnering with a Product Owner on the how is how I already operate at early stage. Happy to share more or jump on a call. Jose Oliveros chinnno15@gmail.com

Shift | AI Engineering Lead | UK | Remote (UK Based only) | Full-time Shift helps enterprises move faster through complex transformation programmes. We're an early-stage UK startup building the AI systems that power how we deliver that work. We're hiring an AI Engineering Lead to own the intelligence layer end to end. You'd own the agent systems, work close to the infrastructure, and set the engineering bar for how the product is built. You'd partner directly with the Product Owner: they own the what and the why, you own the how. It's a high-autonomy role at an early stage. No layers, no politics. Looking for: strong Python, real production experience with LLM APIs (well beyond demos), and a bias for shipping. Container and multi-tenant SaaS experience is a plus. Apply: humans@shiftco.ai
