Job Description

Salesforce is seeking a Machine Learning Engineer to develop and implement features and models that enhance Slack's product. The role involves working with data to drive business impact through machine learning, focusing on practical applications rather than research.

Requirements

  • Experience with functional or imperative programming languages: PHP, Python, Ruby, Go, C, Scala or Java.
  • Built with common ML frameworks like pytorch, Tensorflow, Keras, XGBoost, or Scikit-learn.
  • Experience building batch data processing pipelines with tools like Apache Spark, Hadoop, EMR, Map Reduce, Airflow, Dagster, or Luigi.
  • Worked on generative AI apps with Large Language Models and possibly fine tuned them.
  • An analytical and data driven mindset, and know how to measure success with complicated ML/AI products.
  • Put machine learning models or other data-derived artifacts into production at scale.
  • Led technical architecture discussions and helped drive technical decisions within the team.
  • The ability to write understandable, testable code with an eye towards maintainability.
  • Strong communication skills and you are capable of explaining complex technical concepts to designers, support, and other specialists.
  • Strong computer science fundamentals: data structures, algorithms, programming languages, distributed systems, and information retrieval.

Responsibilities

  • Develop ML models supporting ranking, retrieval, and generative AI use-cases.
  • Brainstorm with Product Managers, Designers and Frontend Engineers to conceptualize and build new features for our large (and growing!) user base.
  • Produce high-quality results by leading or contributing heavily to large multi-functional projects that have a significant impact on the business.
  • Actively own features or systems and define their long-term health, while also improving the health of surrounding systems.
  • Support in the development of sustainable data collection pipelines and management of ML features.
  • Assist our skilled support team and operations team in triaging and resolving production issues.
  • Mentor other engineers and deeply review code.
  • Improve engineering standards, tooling, and processes.

Benefits

  • Employees at Slack, as part of Salesforce, are often offered comprehensive benefits focused on wellbeing and inclusion, including competitive health-care coverage, time off to rest, recharge and volunteer, and holistic programs that support mental health, family planning and overall work–life balance.
