We are building products that make it easy, even effortless, for customers to connect with loved ones—no matter what device or platform they want to start that conversation on. We’re working hard, having fun, and making history; come join us!

Alexa Communications (connecting friends and family) is looking for a Language Engineer to join our Language Understanding Experience team in the area of speech and language data processing. We are seeking a candidate with strong analytical skills and language technology experience to help us measure, analyze and solve complex problems. In this role, you are responsible for the design and delivery of Language Understanding using your linguistic, voice user interface (VUI) design, and data analysis skills to understand what a customer meant. You are a key member in new feature development while proactively improving existing experiences. You work closely with other Language Engineers, Product Managers, Scientists and Engineers to deliver magical experiences that customers love.

Key job responsibilities

Specifically, the Language Engineer will:

  • Contribute to the design of new features by creating or extending annotation schemas to cover new areas,
  • Design the natural language processing components of new Alexa experiences and features by authoring, reviewing and debugging grammars and finite state transducers,
  • Advocate strict adherence to annotation guidelines,
  • Test and deploy changes to Alexa's language understanding codebase,
  • Identify and solve production issues that are impacting the Alexa customer experience,
  • Handle competing requests from a range of data customers,
  • Collaborate with other linguists, scientists and designers in creating optimal solutions to elevate the customer experience,
  • Own the customer-facing machine learning and deterministic models for a specific domain of features, and
  • Use modeling tools to bootstrap and test new functionalities

A day in the life

As an L5 Language Engineer on our team, you develop Alexa NLU for controlling products for Communication, Social, and Photos. You may start your day on your annotation reform project. Performing a deep dive on the annotated data using a Python script you wrote to help identify and visualize inconsistently annotated tokens. You review these visualizations to identify trends and add your findings to your list of proposed annotation changes.

You then switch to a feature development task. At any point you may be working on 2-5 different features in various phases. This particular feature design utilizes a label that previously was not used with this intent so you make a change to the code base and kick off a round of tests. When the tests complete, you will be responsible for analyzing any failing utterances and deciding whether these failures are expected/reasonable given the change you made. Unexpected failures will require you to do further investigations and fixing any issues you may find. After fixing the issue you will kick off another round of tests.

You end your day working on triaging a production issue. You read the customer's report of the issue and begin digging to see if it reveals a bigger problem, writing down your findings along the way. After you find the root cause, you provide your analysis and your mitigation strategy.
