Software Dev Engineer II, AWS Transactional Services (Database & Distributed Systems), Transactional Services

Amazon • Seattle, WA

22h • Onsite

About The Position

The Transactional Services organization at AWS builds foundational distributed systems that power the largest AWS services, specializing in high-performance, strongly consistent data systems operating at massive scale, processing over 4 million writes per second. This role involves working on a multi-year roadmap addressing complex problems such as reducing tail latencies, optimizing cost structures, delivering new capabilities, and enhancing durability, availability, and performance in distributed log systems. As an SDE-II, you will own systems end-to-end, from requirements and design through implementation, deployment, and production support. The work involves deep dives into system internals, including memory layouts, cache behavior, lock-free data structures, and network protocol design. The service is primarily built in Java, with Rust used for performance-critical components. You will troubleshoot complex production issues across distributed components, collaborate with Senior and Principal Engineers, and mentor junior engineers, contributing to the team's technical standards. The position requires strong computer science fundamentals, including algorithmic complexity, concurrency primitives, and understanding distributed systems trade-offs, focusing on building the core systems AWS depends on.

• 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

Nice To Haves

• 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
• Knowledge of professional software engineering & best practices for full software development life cycle, including coding standards, software architectures, code reviews, source control management, continuous deployments, testing, and operational excellence
• Experience with Java or Rust in performance-sensitive environments

Responsibilities

• Design and build highly available, low-latency distributed log and database systems that process millions of writes per second for AWS's most critical services.
• Own end-to-end delivery of software projects from requirements through design, implementation, deployment, and production support.
• Troubleshoot and resolve complex issues in production distributed systems using systematic debugging, performance profiling, and deep analysis of system behavior under failure conditions.
• Design and implement efficient data structures and algorithms optimized for throughput, latency, and memory efficiency in performance-critical paths.
• Identify and execute opportunities to reduce system latency and optimize cost efficiency across the platform.
• Drive improvements to security, reliability, durability, and performance across multiple foundational services.
• Lead and contribute to multi-year, cross-team migration and integration efforts with high-profile partner teams.
• Mentor junior engineers through code reviews, design discussions, and pairing sessions.
• Establish and evolve engineering best practices and operational processes for the team.
