Senior Software Development Engineer (Tech L), DSO (Demand Science Optimization)

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
