Job Description

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. No bureaucracy. No endless meetings. You'll lead a team that ships fast and talks directly to merchants and partners.

At a large company, EMs are disconnected from the product. Here, you'll be technical, close to partners like Shopify and Amazon, and see your team's integrations process thousands of orders per minute.

The Team

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.

A Typical Week

• Monday: Sprint planning. A major merchant wants to expand to a new marketplace. Plan the integration, assign work.

• Tuesday: 1:1s. One engineer shipped a Shopify upgrade handling 3000 orders/minute — recognize. Another wants to lead the framework project — discuss scope.

• Wednesday: Partner call with Amazon. Discuss upcoming API changes, plan migration.

• Thursday: Interview a strong distributed systems candidate. Debrief. Extend an offer.

• Friday: Roadmap review with Product Lead. Balance: new integrations vs. framework investments vs. reliability.

What You'll Own

• Team: 4-6 engineers — hiring, mentoring, performance

• Delivery: Backlog prioritization, sprint execution

• Reliability: SLAs, monitoring, operational excellence

• Roadmap: Technical direction with Product Lead

• Partnerships: Technical relationship with Shopify, Amazon, carriers

What We're Looking For

• 7+ years building software

• 2+ years managing engineers

• Experience with integration platforms or API-heavy systems

• Technical depth in distributed systems, async processing

• You've balanced speed with reliability

• Strong communication with engineers, partners, merchants

Tech Stack

Python, PostgreSQL, Redis, Celery, RabbitMQ, SQLAlchemy, Kubernetes, pytest, Claude Code, etc.

Hiring Process (We move fast)

• Initial interview — Leadership experience, integration systems

• Technical round — Distributed systems, API design

• Interview loop — Leadership scenarios, bar raiser

• Bootcamp — Managers also start in Product Support to learn how merchants use Fulfil

Our Approach to AI

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.
