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:
We are looking for a Principal Architect to take responsibility for the technical architecture and the long-term development of Fulfillment IQ's core integration platform.
This is not a feature delivery role. This is a platform ownership role.
You will operate as the senior technical authority responsible for ensuring our integration architecture is scalable, resilient, high-throughput, and cost-efficient as the platform grows.
This role combines strategic architecture leadership, selective hands-on engineering, and cross-functional technical influence. You will set standards, define architectural direction, and ensure that small inefficiencies today do not become large operational and cost problems at scale.
Must Have:
10+ years of experience building cloud-native backend or platform systems
Proven experience owning architecture for distributed, high-throughput systems
Strong experience with event-driven architectures, APIs, or integration platforms
Deep understanding of cloud infrastructure (Azure preferred) and performance optimization
Experience working with Python-based backend systems and modern cloud architectures
Ability to lead through technical influence rather than formal people management
Nice to Have:
Prior experience with iPaaS platforms, middleware systems, or integration-heavy SaaS products
Experience with streaming technologies such as Kafka, Azure Event Hub, or similar platforms
Exposure to logistics, supply chain, fintech, or data-intensive enterprise systems
Experience with MongoDB or distributed data storage systems
Key Responsibilities:
Architecture & Standards
Own end-to-end architecture for FIQ's integration platform
Design scalable, event-driven and API-based integration patterns
Establish architectural standards and "golden path" development practices
Define patterns for connectors, transformations, retries, fault tolerance, and observability
Performance & Optimization
Identify architectural bottlenecks before they scale
Optimize compute, memory, I/O, and cloud infrastructure costs
Ensure platform reliability under increasing workloads
Lead architectural reviews and enforce design standards
Technical Leadership
Act as primary technical gatekeeper for platform decisions
Build POCs for complex integrations and architectural patterns
Unblock technically complex challenges across teams
Translate customer requirements into scalable technical designs
Collaboration
Partner with Product, Engineering, and Infrastructure teams
Communicate trade-offs, risks, and long-term implications to stakeholders
Maintain clear technical documentation
What Success Looks Like in the First 90 Days:
30 Days In
Develop a deep understanding of Fulfillment IQ's integration platform, architecture, and technical roadmap
Build strong working relationships with Engineering, Product, and Infrastructure teams
Review current platform design, performance bottlenecks, and architectural risks
Identify quick-win optimization opportunities and priority architectural gaps
60 Days In
Establish clear architectural standards and platform design guidelines
Deliver at least one Proof of Concept or reference implementation for a priority integration challenge
Begin improving performance, scalability, or cost efficiency in at least one core platform area
Introduce structured architecture review processes
90 Days In
Present a forward-looking platform architecture roadmap to leadership
Demonstrate measurable improvement in system reliability, performance, or operational efficiency
Ensure teams are aligned on platform standards and architectural direction
Establish a clear long-term technical vision for the integration platform
Key Performance Indicators (KPIs):
Reduced integration failures and platform incidents
Improved throughput and performance under load
Adoption of standardized patter
