Original job description

Amazon’s Worldwide Deals and Promotions organization builds the systems that compute and apply promotional benefits to hundreds of millions of customer orders every day. The Promotions Calculations Lifecycle (PCL) team owns the checkout-time calculation path: deciding which promotions apply to a cart, how benefits combine, and what the customer ultimately pays - correctly, at low latency, and at worldwide scale.

We are looking for a Software Development Engineer II (SDE II) to own the design, build, and operation of services on this critical path. You will work on high-throughput, low-latency systems where correctness is customer-facing and measured in real money. This is a hands-on engineering role for a builder who enjoys deep technical ownership, solving ambiguous problems with team members, and raising the operational bar for services that must work worldwide on Day 1.

Key job responsibilities

Own end to end the design, implementation, testing, deployment, and operation of components and services on the promotions calculation path, from design document through post-launch monitoring.
Design and build scalable, low-latency services and features that compute promotional benefits correctly at checkout for customers worldwide.
Raise code quality through thorough, timely code reviews, strong testing practices, and secure, maintainable, well-instrumented code.
Drive operational excellence - participate in on-call, reduce operational load through automation, and constructively identify and fix sources of defects and toil.
Collaborate across teams with partner engineering teams, product managers, and stakeholders to deliver cross-functional initiatives that span multiple months.
Work through ambiguity by breaking down loosely defined problems, unblocking yourself and others, and making pragmatic decisions that move the team forward.
Mentor and uplevel peers and newer engineers through design feedback, pairing, and knowledge sharing.

A day in the life A typical week combines focused building with the collaboration and operational rigor that keep a Tier-1 service healthy. You might start the day reviewing a design document for a change to how benefits combine at checkout, then pair with a teammate on the Universal Benefit Service (UBS) to reduce calculation latency on a high-traffic path. You will write and review code, add tests and metrics, and ship changes through the team’s continuous deployment pipeline.

You will take part in the on-call rotation for services the team owns, using operational signals to find and remove recurring sources of defects and toil. You will work with partner teams across Worldwide Deals and Promotions, and with product managers, to turn ambiguous requirements into concrete designs. You will also invest in the people around you - giving design feedback, mentoring newer engineers, and sharing what you learn so the whole team levels up.

About the team The Promotions Calculations Lifecycle (PCL) team sits within Amazon’s Worldwide Deals and Promotions organization. We own the checkout-time path that determines which promotions apply to a customer’s cart, how those benefits combine, and the final price the customer pays. Our services run worldwide and are on the critical ordering path, so correctness, availability, and latency are first-order requirements - the systems we build directly shape both the customer experience and Amazon’s financials.

We are a team of builders who value deep technical ownership, operational excellence, and raising the bar for one another. We invest in mentorship and career growth, work backwards from the customer, and take pride in making complex systems simpler and more reliable over time. You will join a group where your work is highly visible, your decisions matter, and there is ample room to grow as an engineer. Basic qualifications

3+ years of non-internship professional software development experience
2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
1+ years of software development engineer or related occupational experience
1+ years of designing and developing large-scale, multi-tiered, multi-threaded, embedded or distributed software applications, tools, systems, and services using: C#, C++, Java, or Perl experience
1+ years of Object Oriented Design experience
Bachelor's degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related field
Experience programming with at least one software programming language Preferred qualifications
3+ 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
