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 patterns across teams
- Reduced technical debt and architectural rework
- Improved resource utilization and cost efficiency
