About Fulfillment IQ (FIQ):

Fulfillment IQ is a supply chain engineering and transformation company that helps brands, retailers, and 3PLs design, build, and scale high-performance logistics operations. 

We work at the intersection of strategy, operations, and technology where we solve complex, real-world problems across warehouse design, automation, order management, transportation, and end-to-end supply chain execution. 

Our teams combine deep domain expertise with strong technical capability, delivering outcomes through consulting, systems implementation, and proprietary platforms that accelerate time-to-value and reduce delivery risk. 

If you enjoy working in complex environments, partnering closely with clients, and seeing your work make a tangible impact on how global commerce moves, this is the place where your skills and judgment truly come to life. 

Role Overview

As a Backend Engineer III, you will build the services, data models, and APIs that power a new greenfield platform at the core of FIQ's supply chain technology. You will write the business logic and processing workflows that everything else depends on, with a focus on data integrity, correctness, and performance. Working alongside the founding engineer and full-stack team, your work will form the reliable backbone the rest of the product is built on.

Key Responsibilities:

• Design and build backend services, APIs, and data models
• Implement business logic and processing workflows
• Design relational schemas and manage database migrations
• Ensure data integrity, correctness, and API performance
• Write tests and contribute to shared engineering standards

• Participate in code review and technical design
• Help evolve the backend architecture as the platform scales

Must Have:

• 4-6 years of experience building backend services and APIs
• Strong, hands-on Python fluency; you will write production Python from day one
• Experience designing and building REST APIs, ideally with FastAPI, Flask, or Django
• Strong relational database skills, including schema design and SQL (PostgreSQL or similar)
• Experience with ORMs and data modeling
• Ability to translate requirements into robust, production-ready backend systems
• Strong engineering fundamentals across performance, reliability, and maintainability
• Comfort operating in a fast-moving, early-stage environment with high ownership

Nice to Have:

• Experience with AI-driven development and AI-assisted engineering workflows
• Experience with LLM-integrated development, including RAG and retrieval-augmented patterns
• Experience with FastAPI, SQLAlchemy, and Alembic
• Experience with multi-tenant systems or complex data models
• Experience building workflow engines, pipelines, or DAG-based processing
• Familiarity with CI/CD, containers (Docker), and cloud infrastructure
• Experience with calculation engines, rules engines, or deterministic data pipelines
• Exposure to logistics, supply chain, fintech, or data-intensive SaaS platforms
