Role Overview

Zynque is FIQs integration platform (iPaaS) for supply chain and logistics. After a year of development it is live in production with active customers onboarding and it now needs to grow into an enterprise-grade high-throughput platform.

This is not a greenfield role and it is not a maintenance role. It is a scale-up role: take a young production platform and harden it into a system that enterprises trust with their operations. You will own the architecture as it evolves under real load with real customers while the platform keeps shipping.

Must Have:

• 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 ()
• Hands-on daily coder with founder-level ownership; comfortable in low-process high-ambiguity environments

Nice to Have:

• Built or scaled an integration platform ETL/data pipeline product or API platform (connectors transformation pipelines webhooks)
• Kafka or similar streaming infrastructure at scale
• Supply chain or logistics systems exposure (WMS OMS TMS EDI integrations)
• AI-assisted engineering workflows; AI is deeply embedded in how we build
• Experience shipping AI/LLM-driven capabilities in production (rag generation pipeline agentic workflows)

Key Responsibilities:

• 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

What Success Looks Like in the First 90 Days:

• 30: Deep command of the codebase and production topology; shipping to production; documented view of the top scaling and reliability risks
• 60: First major scaling or reliability improvements live; observability and SLO baseline established
• 90: Enterprise-readiness roadmap owned and in motion; measurable gains in throughput latency or stability

Key Performance Indicators (KPIs):

• Platform uptime and reliability
• Throughput and latency under growing customer load
• Customer and integration onboarding velocity
• Incident frequency and time to recovery
• Enterprise scalability readiness
