Fulfil is a technical founder-led, bootstrapped company in our 11th year of operations. We're a small team of exceptional engineers powering millions of orders for brands like HexClad, Ridge Wallet, and Caraway. No red tape. No product managers. No layers of approval. You won't be buried in meetings — you'll drive technical direction while still shipping code.
At a large company, leads attend syncs and write roadmap decks. Here, you'll design integration systems that process thousands of orders per minute and mentor the engineers who build them.
Integration Platform owns all external connections: Shopify, Amazon, marketplaces, 3PLs, carriers, EDI. We process thousands of orders per minute. North star: integrations are reliable, scalable, debuggable, and fast to build.
Monday: Define Q2 technical roadmap with Product Lead. Three major merchants expanding to new channels. Prioritize the platform work.
Tuesday: Deep dive on Shopify sync performance. Design a path to handle 10x current volume.
Wednesday: Mentor a Senior Engineer on their first framework project. Review design, push back on over-engineering.
Thursday: Ship a critical fix yourself. Some weeks 80% code, some weeks 20%.
Friday: Interview a Staff Engineer candidate. Debrief. Make the call.

What We Do
Leverage LLMs (OpenAI API, Claude API) to embed AI-driven capabilities into Fulfil’s ERP, powering natural language interfaces, intelligent automation, and merchant-facing insights (e.g., Fulfil x MCP integrations with Claude).
Focus on AI for commerce operations — integrating models to solve real problems like order management, financial analysis, customer insights, and logistics optimisation.
What We Don’t
We are not a core ML/AI research company — we don’t train or fine-tune foundation models.
We focus on integration and productisation of AI, not building new ML frameworks or developing custom model architectures.
