Software Engineer, Logistics Platform

Whatnot is hiring a Senior Software Engineer for its Logistics Platform team. The role builds and improves the shared backend systems, data, APIs, and tools that support logistics workflows, operational debugging, and trustworthy shipping experiences.

Responsibilities:

• Build and improve source-of-truth systems, APIs, and internal platform interfaces that other teams depend on for logistics workflows and decisions
• Own backend and platform work across logistics data quality, shipment state normalization, observability, and operational debugging surfaces
• Partner closely with Product, Data Science, CX, Ops, Trust, and Finance to turn messy real-world logistics problems into durable systems and better user outcomes
• Improve the correctness, timeliness, and usability of the logistics data that powers support, trust, product, and operational workflows
• Build tooling, monitoring, and debugging primitives that help teams detect problems earlier and get to truth faster
• Use AI thoughtfully in day-to-day engineering work to improve quality, learning speed, debugging, and execution — while keeping a strong independent bar for correctness and risk judgment

Requirements:

• Experience building and owning meaningful backend or platform systems in production at the senior scope — i.e. developing and owning moderate-to-complex software, disambiguating meaningful problems, and collaborating effectively with stakeholders and cross-functional partners
• Strong product judgment and the ability to connect technical work to user impact, business outcomes, and explicit trade-offs
• Experience in complex marketplace, coordination, delivery, fulfillment, trust, or post-purchase systems where software decisions interact with messy real-world state
• Strong instincts around data quality, source-of-truth systems, observability, and operational debugging
• A thoughtful approach to AI: not just using AI for more output, but using it to improve the quality of engineering work while knowing where verification and independent judgment still matter
• Comfort operating in fast-moving, high-ownership environments with ambiguity and shifting priorities
• Experience in adjacent domains like rideshare coordination, food delivery, marketplace fulfillment, trust/risk operations, or order tracking and exception-handling systems
• Experience working on a marketplace or other two-sided platform
• Direct experience in logistics, shipping, or fulfillment systems
