Why Fulfil

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.

#

The Team

Finance owns accounting, reconciliation, revenue recognition, and financial integrations. North star: books close on time with transactions posted automatically.

#

A Typical Week

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.

Our Approach to AI

What We Do

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.
