Staff Software Engineer(WMS & Supplychain)

Staff Software Engineer – Global Supply Chain Logistics

Purpose

As a Staff Software Engineer – Carrier & Logistics Platforms, you will design and evolve carrier management, shipping execution, LTL freight flows, returns, and post-shipment delivery platforms across eCommerce and wholesale fulfillment.

This role is hands-on and architecture-driven, focused on building scalable, resilient logistics systems, setting technical standards, and solving complex cross-domain problems spanning carrier integrations, transportation systems, and customer delivery visibility.

Key Responsibilities

• Architect and evolve enterprise-scale carrier management and shipping execution platforms, supporting parcel, LTL, returns, and multi-node fulfillment flows.
• Design and standardize carrier integration patterns for rate shopping, label generation, tendering, tracking, billing, and carrier event ingestion, integrating with platforms such as ProShip, Shipium, ConnectShip, and similar solutions.
• Lead the design and optimization of LTL freight workflows, including rating, routing, tendering, exception handling, and post-shipment reconciliation.
• Shape the post-shipment delivery experience architecture, including real-time tracking, proactive exception management, customer notifications, and delivery promise alignment, integrating with post-purchase platforms such as Narvar.
• Design and scale returns and reverse-logistics platforms, covering carrier selection for returns, label generation, RMA orchestration, tracking, and disposition lifecycle.
• Partner closely with WMS, OMS, and TMS teams to ensure end-to-end order-to-delivery and returns lifecycle correctness across systems.
• Design event-driven, highly available systems capable of processing high-volume shipment and carrier events with strong guarantees around reliability, idempotency, and observability.
• Establish and reinforce platform-wide standards for system design, reliability, and observability, influencing architectural consistency across teams.
• Mentor senior engineers and influence technical decision-making across domains, translating logistics and operational constraints into scalable technical solutions that improve cost, speed, and customer experience KPIs.

Qualifications & Experience

• 10+ years of software engineering experience, with deep specialization in logistics, shipping, transportation, or supply-chain platforms.
• Proven experience contributing to and shaping large-scale carrier management or shipping execution systems operating in production at high volume.
• Extensive hands-on experience integrating with carrier and shipping platforms such as ProShip, Shipium, ConnectShip, Logistyx, BluJay, or equivalent solutions.
• Strong expertise in parcel and LTL shipping workflows, including rate shopping, freight tendering, carrier compliance, exception management, and reconciliation.
• Demonstrated experience designing and scaling returns and reverse-logistics systems.
• Deep understanding of post-shipment delivery visibility, carrier event models, delivery promise alignment, and customer notification pipelines.
• Advanced proficiency in Go, Java, or Python, with a track record of building distributed, highly available backend systems.
• Strong architectural experience with microservices, event-driven systems, asynchronous processing, and data consistency patterns.
• Extensive experience with cloud platforms (AWS, GCP, or Azure) and messaging/streaming technologies such as Kafka or SNS/SQS.
• Experience designing delivery promise logic, transit-time estimation models, and shipping cost optimization strategies.
• Exposure to Transportation Management Systems (TMS), freight execution platforms, workflow orchestration frameworks (e.g., Temporal), and international or cross-border shipping flows.
• Proven ability to lead cross-team technical initiatives, influence without authority, and align engineering execution with business outcomes in high-volume eCommerce or omnichannel fulfillment environments.
