Amazon moves millions of packages daily through a global logistics network of Fulfillment Centers Sort Centers and Delivery Stations. Every facility has a trailer yard the physical space where line-haul vehicles arrive get loaded or unloaded and depart. Tracking whats happening in these yards in real time (which trailers are where what state theyre in whos arriving and departing) is a hard problem that sits at the intersection of physical operations and software systems. The Relay Yard Automation (RYA) team builds the software that manages these trailer yards across 6000 Amazon facilities on three continents. Our products handle 200K gate transactions per day and facilitated the arrival and departure of 55M vehicles last year. We integrate computer vision RFID GPS ultrasonic sensors and IoT edge devices to automate what were historically manual associate-staffed processes from gate check-in/check-out to in-yard trailer movements. Our gate automation program has already eliminated millions of manual transactions with a long-term goal of fully autonomous yard operations. The tech stack is diverse by necessity: Android mobile apps for yard associates and drivers React web applications for remote gate agents and yard operators Java/ TypeScript backend services on AWS and hardware integrations running on edge compute devices deployed in the field. Systems are loosely coupled event-driven and must operate reliably in environments ranging from 1M sq ft North American fulfillment centers to small urban European delivery stations.
As a Senior SDE on this team you will lead the design and implementation of our most complex and ambiguous technical initiatives. You will own architecture decisions for team-level systems write critical-path code and drive projects from problem definition through production launch. The role requires someone who can operate across the full stack integrate with physical sensor systems at the edge and make pragmatic trade-offs between delivery speed and long-term extensibility. You will influence technical direction across partner teams in Transportation Technology raise the engineering bar through design reviews and exemplary artifacts and mentor junior engineers. You will own operational excellence for the services you build tier-1 systems where your decisions directly impact driver experience and Amazons ability to meet customer delivery promises.
Key job responsibilities
- Design and implement software for yard and gate automation products across tier-1 systems. Your code runs in production where defects directly impact driver experience and customer delivery promises.
- Lead large projects end-to-end: define the technical approach in ambiguous problem spaces decompose work into parallel workstreams and deliver cohesive launches.
- Own system architecture for your teams services. Proactively simplify code resolve architecture deficiencies and remove bottlenecks across Java backend services TypeScript/React web apps Android mobile apps and IoT edge devices.
- Make short-term vs. long-term trade-off decisions and communicate them clearly to your team and stakeholders.
- Integrate with physical systems RFID readers computer vision cameras ultrasonic sensors GPS running on edge compute in variable warehouse environments. Debug problems that span hardware and cloud software.
- Own operational excellence for services you build: monitoring alarming runbooks incident response and root-cause corrective actions.
- Influence technical direction beyond your team through design reviews with partner teams across Transportation Technology.
- Act as a force multiplier. Raise the engineering bar through code reviews design artifacts and reusable frameworks. Mentor junior engineers toward their next level.
- 5 years of non-internship professional software development experience
- 5 years of programming with at least one software programming language experience
- 5 years of leading design or architecture (design patterns reliability and scaling) of new and existing systems experience
- Experience as a mentor tech lead or leading an engineering team
- Bachelors degree in computer science or equivalent
- 5 years of full software development life cycle including coding standards code reviews source control management build processes testing and operations experience
