Full-Stack Engineer (AI-Native) in London

About DELLIDELLI exists to empower the independent economy, the makers, creators, and producers whose craft shapes the way the world tastes, feels, and connects. We imagine a world where every maker has a companion; a quiet, intelligent partner who handles the chaos so they can stay focused on the joy of creating.

Every day, millions of small businesses lose hours to invisible labour — the unseen admin, the back‐and‐forth messages, the clarifications, the late‐night catch‐up that keeps everything moving. It’s the unspoken cost of being independent, and it steals time and energy from the work that actually matters. We believe commerce should feel natural again.

A baker shouldn’t have to wrestle with emails, calls, spreadsheets and tools that don’t talk to each other. A retailer shouldn’t need to scan across fragmented channels just to understand who has stock or what’s available. In the world we’re building, AI agents become the connective tissue, listening across conversations, interpreting intent, and quietly taking care of what needs to happen next. They reduce noise, restore clarity, and give makers and retailers the freedom to operate the way they already do, but with far more ease, confidence, and flow.

It’s intelligence that feels human, supportive, and alive — technology that steps in without stepping over. We’re starting in food, where culture, community, and craft collide most powerfully. What we learn here will shape how we support other categories across the independent economy, amplifying the people who make our world more interesting, more human, and more alive.

Your Role: Join us as a Full‐Stack Engineer and help build the foundation of DELLI's agentic platform. You’ll work across the entire stack, from the intelligence powering our Order and Payments Hubs to the infrastructure that keeps everything running smoothly. This is a hands‐on role where you’ll build, ship, and learn quickly based on feedback from real makers who rely on what we create.

You’ll be part of a collaborative engineering team where everyone contributes to architecture, problem‐solving, and delivery. Instead of being limited to a narrow slice of the system, you’ll work across platforms end‐to‐end. You’ll architect, build, deploy, and iterate in an environment that values autonomy, trust, inclusivity, and thoughtful engineering. We’re looking for someone excited to help create something new and meaningful. The work you do here will shape the future of independent commerce.

Responsibilities: You’ll design and build core features across the Order, Payments, and Discovery Hubs, working closely with the team to make technical decisions and carry them through to implementation. You’ll take responsibility for what you build and when you deliver it, while working in a supportive and collaborative environment. You’ll shape backend systems, contribute to frontend flows, and support the infrastructure on AWS with tools like Terraform. You’ll ship quickly, gather feedback, and iterate based on the needs of real makers. Your work will also include supporting deployments, monitoring, and ensuring our systems run securely and reliably. As the platform grows, you’ll help refine product direction and engineering standards.

What We’re Looking For:

• Must‐haves: Full-stack capability across backend (Node and Python), frontend (Next.js and React), and strong experience with TypeScript. Experience with AWS, CI/CD, and infrastructure tooling such as Terraform. Familiarity with MCP, LangChain, or equivalent frameworks for agentic or AI‐powered systems. Curiosity about intelligent software design and how AI should shape modern architecture. A builder mindset focused on learning quickly and delivering real impact. Comfort working with autonomy in open problem spaces.
• Nice‐to‐haves: Experience integrating LLMs or other AI systems into production environments. Background in early‐stage companies and an understanding of the zero‐to‐one journey. Interest in payments infrastructure. Early‐stage startup experience, you know what 0→1 feels like. Empathy for non‐technical users and a desire to design clear, accessible experiences.

Why Join DELLIEarly ownership — help shape the architecture, product direction, and technical standards that define how the independent economy runs. Direct impact — your code powers real businesses; every feature you ship saves makers hours and gets them paid faster. True autonomy — small, flat, senior team; no red tape, just clear ownership and shared ambition. Frontier learning — build in one of the most exciting frontiers of software - agentic AI and real‐world commerce infrastructure. Top‐tier backing — supported by Balderton Capital and HV Capital, building with intent and long‐term conviction. Purpose that matters — you’re not optimising clicks; you’re building systems that sustain culture, creativity, and independence.

We’re at that rare inflection point — early enough that your fingerprints will be everywhere, but real enough that your work ships to makers every week. If you want to build foundational systems that change how the world’s independent economy operates, this is your moment.

Practical Details: Location: UK based, London hybrid with two days in the office. Start date: January or February 2026. Compensation: Competitive salary and meaningful early stage equity. Team: Collaborative engineering team with high autonomy and shared ownership.
