Senior Software Development Engineer driving the re-architecture of Amazon Devices' pricing and assortment planning platform — the system that decides what devices sell where, when, and at what price, across every Amazon device sold worldwide. This role owns the design and delivery of a new domain-modeled system: collapsing a fragmented legacy input pipeline into an automated platform that determines pricing and retailer placement for over 21,000 products across 7 device families and 22+ countries.

The team's scope is growing, and you will shape how it grows.

What you will work on:

- Setting technical direction and architecture across the services the team owns
- Raising the engineering bar through design review, code review, and operational standards
- Aligning with engineers on partner teams on shared interfaces and ownership boundaries
- Replacing recurring manual work with automation and better design
- Mentoring engineers as they grow into deeper technical ownership

Key job responsibilities
- Design, build, and operate the most technically complex parts of the input layer, using AI-assisted development and agents to replace work that is manual today
- Set technical direction and architecture, including decisions to consolidate, rebuild, or retire systems
- Lead design and code reviews, and define the operational standards a service meets before the team owns it
- Partner with product managers, scientists, and engineers on other teams to turn requirements into designs and to align on shared interfaces and ownership boundaries
- Mentor engineers through design guidance, written documentation, and pairing

A day in the life
Your primary focus is the layer of inputs that Amazon's device planning, forecasting, and inventory systems all read from. A handful of services, and every build and allocation decision downstream depends on them agreeing.

You're rebuilding that layer to easily allow stakeholders to manage a whole product line's inputs for high-impact decisions. You'll make the calls on what that architecture looks like.

Beyond this system, an Sr. SDE in DSO is expected to operate across charters — bringing technical judgment to whichever part of the org needs it most at a given time, representing the team in cross-charter design discussions, and mentoring engineers across projects.

About the team
We own the inputs Amazon's device planning, forecasting, and inventory systems depend on — the data behind what gets built, where it ships, and at what price. Our customers are internal: the planners who own each product line, finance partners, and the science and engineering teams downstream. You'll work with them directly.
We're rebuilding it so each input lives in one place and stays correct without someone tending it, moving toward agent-based interfaces.

Basic qualifications

- 7+ years of non-internship professional software development experience
- 7+ years of programming with at least one software programming language experience
- 7+ 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

Preferred qualifications

- 7+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
- Bachelor's degree in computer science or equivalent
