Senior Software Development Engineer in Sunnyvale, California

Alexa is the groundbreaking cloud-based intelligent agent that powers Echo and other devices designed around your voice. Our mission is to push the envelope in Natural Language Understanding (NLU), Machine Learning (ML), Dialog Management, Automatic Speech Recognition (ASR), and Audio Signal Processing, in order to provide the best-possible experience for our customers. We’re looking for a Senior Software Development Engineer to help build industry-leading conversational technologies and machine learning systems that customers love.

As a Senior Software Development Engineer for the Alexa team, you will be responsible for translating business and functional requirements into concrete deliverables with the design, development, testing, and deployment of highly scalable distributed services. You will also partner with scientists and other engineers to help invent, implement, and connect sophisticated algorithms to our cloud based engines. Prior domain knowledge including ML, ASR, and NLU is a preferred, though not required. However, strong motivation to learn ML, ASR and NLU is critical for successful candidates. Candidates should also be very agile in developing flexible software with respect to scientific, experimentation methods and usage patterns. Additional responsibilities include:

  • Leading the development and maintenance of core system features

  • Helping define product features, drive the system architecture, and spearhead the best practices that enable a quality product

  • Working with scientists and other engineers to investigate design approaches, prototype new technology, and evaluate technical feasibility

  • Operating in an Agile/Scrum environment to deliver high quality software against aggressive schedules

  • Establish architectural principles, select design patterns, and mentor team members on their appropriate application

  • Graduate degree (MS or PhD) in Electrical Engineering, Computer Science, Mathematics, or related technical field

  • Experience with programming languages such as C/C++, Java, Perl or Python and open-source technologies (Apache, Hadoop)

  • Knowledge of OO design and common design patterns

  • Experience with data structures, algorithm design, problem solving, and complexity analysis

  • Experience defining system architectures and exploring technical feasibility trade-offs

  • Demonstrated track record of project delivery for large, cross-functional projects with evolving requirements

  • Experience developing cloud software services and an understanding of design for scalability, performance and reliability

  • Proven track record of innovation in creating novel algorithms and advancing the state of the art

  • Experience optimizing for short term execution while planning for long term technical capabilities

  • Ability to rapidly prototype and evaluate applications and interaction methodologies

  • Ability to produce bullet-proof code that is fault-tolerant, efficient, and maintainable

  • Academic and/or industry experience with standard AI and ML techniques, NLU, and scientific thinking

  • Experience working effectively with science, data processing, and software engineering teams

  • Ability and willingness to multi-task and learn new technologies quickly

  • Strong project management experience, working on cross-functional projects

  • Excellent written and verbal technical communication with an ability to present complex technical information in a clear and concise manner to a variety of audiences
