Job summary

Amazon.com Services LLC in Boston, MA seeks a Senior Software Development Engineer to lead the technical direction of CI systems for EBS. You will design architectures, orchestrate vast test suites, and apply AI-driven techniques to improve coverage and efficiency.

You will mentor engineers, partner with EC2/EBS teams, and shape CI reliability at AWS scale. This role requires strong leadership and a focus on secure, observable, self-healing infrastructure.

Qualifications

• 5+ years of non-internship professional software development experience.
• 5+ years of programming with at least one software programming language.
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems.
• Experience as a mentor, tech lead or leading an engineering team.

Responsibilities

• Drive technical design and architecture for CI systems that validate EBS server code changes across multiple hardware architectures with fast, reliable signal.
• Architect distributed test orchestration infrastructure that runs thousands of test suites daily, giving developers confidence in what they ship.
• Drive shift-left testing strategies and quality frameworks that catch defects earlier in the development cycle — emphasizing quality, agility, frugality, and engineering efficiency across the CI pipeline.
• Design intelligent test selection and qualification systems using AI/ML — cutting qualification time without sacrificing coverage.
• Build secure, automated operational infrastructure for CI services — ensuring availability, observability, and autonomous recovery.
• Design memory safety and performance profiling infrastructure that detects spatial/temporal errors, race conditions, and regressions at scale.
• Drive toward AI-native CI — automated test generation, intelligent code review, predictive failure analysis, and debugging assistants.
• Optimize CI infrastructure costs while maintaining quality (thousands of server-hours per release cycle).
• Lead design reviews, raise the engineering bar through code reviews, and establish best practices for CI reliability and developer experience.
• Mentor engineers across levels and contribute to a team culture of technical excellence and operational rigor.
