Principal Engineer - Zynque

Fulfillment IQ is a supply chain engineering company. Zynque is their integration platform (iPaaS) for supply chain and logistics. The role is to take the young production platform and harden it into an enterprise-grade, high-throughput system, owning the architecture and scaling it under real load with active customers.

• Own technical direction and architecture evolution of a live, revenue-generating platform
• Scale throughput and reliability while customers onboard, including zero-downtime changes to running systems
• Harden the platform: tenant isolation, rate limiting, security, data integrity
• Establish observability, SLOs, and incident practices as the customer base grows
• Lead performance and capacity work ahead of demand, not behind it
• Raise engineering standards through design reviews and mentorship
• Partner with Product to balance platform investment against feature delivery
• Identify and retire scaling risks and technical debt before they compound

• 10+ years building and operating cloud-native backend or platform systems
• Owned the scaling of a production SaaS or data platform through rapid customer growth: hardening, re-architecture under load, and maturing an early product to enterprise grade
• Deep hands-on experience with high-throughput distributed systems: event streaming or message queues, async processing, idempotency, retries, backpressure
• Strong performance engineering: profiling, load testing, horizontal scaling, capacity planning
• Production reliability ownership: observability, SLOs, incident management, fault-tolerant design
• Multi-tenant SaaS experience, including tenant isolation and noisy-neighbor problems
• Proficiency in Python and JavaScript/TypeScript (Next.js)
• Hands-on daily coder with founder-level ownership; comfortable in low-process, high-ambiguity environments
• Built or scaled an integration platform, ETL/data pipeline product, or API platform (connectors, transformation pipelines, webhooks) - Nice to have
• Kafka or similar streaming infrastructure at scale - Nice to have
• Supply chain or logistics systems exposure (WMS, OMS, TMS, EDI integrations) - Nice to have
• AI-assisted engineering workflows; AI is deeply embedded in how we build - Nice to have
• Experience shipping AI/LLM-driven capabilities in production (rag, generation pipeline, agentic workflows) - Nice to have

• Work That Matters: Build systems that directly impact global commerce and supply chain performance
• Career Growth That Matters: mentorship, leadership development, learning budgets, long-term career growth
• Flexibility to Thrive: remote and hybrid work models, multiple office locations
• We Celebrate You: recognition, milestone celebrations, performance rewards
• A Collaborative Culture: talented engineers, product leaders, domain experts
• Employee Health: comprehensive health and dental coverage for you and your family
• Time Off: competitive paid time off and flexible leave policies
• Retirement: retirement savings programs and employer contributions
• Professional Growth: dedicated learning and development budget
• Flexible Work: remote and hybrid work options
• Perks: equipment allowances, internet reimbursements, business travel coverage, employee stock options (ESOP)
• Community Engagement: team events, meetups, company offsites
