Senior Full Stack Engineer (Next.js / AI / Creator Commerce)

## About the Role Build the operating system for creator commerce. Lumo is building the AI operating system behind TikTok Shop and Instagram affiliate marketing. We help brands discover creators, automate outreach, manage affiliate relationships, track performance, and scale creator-led revenue, without the spreadsheets, fragmented tools, and manual workflows that currently dominate the industry. Think: - Salesforce meets creator commerce. - Linear meets influencer marketing. - AI agents replacing repetitive agency work. We're already live with paying brands and are now expanding into Instagram while building the next generation of AI-native tooling for social commerce. We're a very small team moving very fast: - CTO - QA - AI Engineer - 2 Founders This is not a maintenance role. You'll help shape the product, architecture, and direction of the company from an early stage. The Role We're looking for a true product engineer. Someone genuinely comfortable moving across the stack and shipping features end-to-end, from database schema to backend router to polished frontend UI. You'll work directly with the Founding Engineer and AI Engineer across both the TikTok and Instagram products, helping build systems used daily by real brands managing creator campaigns at scale. You should enjoy: - owning features from idea to production - building clean product experiences - thinking deeply about UX and system design - working quickly without sacrificing quality - reading existing systems and extending them properly - startup environments with high ownership and low bureaucracy The codebase is structured, documented, and already live in production, but we need someone who can quickly understand patterns, work independently, and ship confidently. ## What You'll Build First 30 Days You'll work on one of the most important infrastructure changes in the platform: making the entire product platform-aware across TikTok and Instagram. This includes: - platform switcher architecture - extending the existing shop selector - platform-context aware dashboard pages - shared component abstraction patterns - cross-platform UI consistency This touches almost every area of the app and requires someone who can ramp up quickly and think systematically. First 90 Days You'll help build the Instagram expansion across: - Creator Radar - CRM Kanban pipelines - Instagram acquisition workflows - DM window countdown systems - campaign creation flows - catalogue health dashboards - outreach and cold email infrastructure tooling Ongoing You'll help build the Creator Portal: a completely new authenticated experience for creators using Lumo. This includes: - earnings dashboards - affiliate links - creative brief delivery - direct messaging with brands - creator onboarding and account systems As the platform grows, you'll continue extending both the frontend and backend systems across TikTok and Instagram. ## Our Stack At Lumo, "full stack" genuinely means full stack. ## What We're Looking For You've already bu
