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. You won't be buried in meetings — you'll drive technical direction while still shipping code.
At a large company, leads write strategy docs. Here, you'll design financial systems, mentor engineers, and see your decisions impact merchants processing millions of dollars.
Finance owns accounting, reconciliation, revenue recognition, and financial integrations. North star: books close on time with transactions posted automatically.
Monday Define the technical roadmap for Q2 with Product Lead. A major merchant needs multi-entity consolidation before their audit. Prioritize.
Tuesday Deep dive on reconciliation performance. Design a path from 85% auto-match to 98%.
Wednesday Mentor a Senior Engineer on their first architecture project. Review their design, push back on unnecessary complexity.
Thursday Ship a critical fix yourself. Some weeks you're 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.
Fulfil is the only ERP designed for eCommerce & wholesale merchants. With the rise in multi-channel commerce, Fulfil was built with the simple idea that merchant operations need to be simplified in order to deliver amazing retail experiences. Fulfil enables businesses to turn their back office operations into an accelerator for growth by integrating order management, inventory management, warehouse management, purchasing, wholesale, manufacturing, financials and customer service; all into one seamless solution. We believe merchants should love their operations platform, and we work hard to make that happen every single day.
