Senior Machine Learning Engineer
Fizz
Palo Alto, CA
Who we are
Fizz is a private and authenticated platform designed to revolutionize the social fabric of communities, starting with colleges. After verifying a university email address, students use Fizz to post questions, memes, polls, and chat directly with other verified students, all while maintaining full control of their identity and privacy. Fizz communities are safe, authentic, and inclusive, made possible through community-based moderation.

Launched by two Stanford dropouts, Fizz is currently expanding into colleges all across the US. In a time when social media is plagued by curated highlight reels and lack of authenticity, Fizz is on a mission to redefine the definition of a true social network.

What we’ve done
We first launched Fizz at Stanford in July 2021 and have since seen >95% of undergraduates join the app, half of which use Fizz every day. Since then, we have raised over 16M from NEA, Owl Ventures, and Lightspeed, built a rock-solid engineering team with decades of experience at top tech companies, and expanded Fizz to be the dominant community platform at 70+ colleges.

Where we’re going
Our near term goal is to expand to all US universities by the end of the 2023-2024 academic school year. To get there, we give engineers at Fizz a lot of autonomy and ownership of our product. Some of the things you can expect to work on include:
- Building and maintaining scalable human in the loop AI community moderation systems
- Utilizing NLP systems to automatically categorize and target content to users
- Conducting analysis on larger amounts of user-generated content and using data to drive product decisions

We are open to candidates of all experience levels who are passionate about being an early employee and want to help drive our company forward.

Responsibilities

    • Design and implement machine learning models and algorithms to solve specific user problems
    • Develop in-house human in the loop moderation systems to detect and prevent inappropriate content and behavior on our platform
    • Develop and maintain data pipelines and infrastructure to support machine learning workflows
    • Work closely with the front-end team to implement content moderation and content recommendation systems
    • Keep up-to-date with emerging trends and best practices in machine learning and AI development

Qualifications

    • Strong understanding of machine learning techniques and algorithms (natural language processing, generative AI, content recommendation)
    • Experience as a lead engineer for at least one large scale system that supports at least a million users using a distributed system.
    • Familiarity with designing RESTful APIs that are scalable, reliable, and secure
    • Strong grasp on product and ability to develop a product that college students will use and love.
    • Passion for building intelligent systems that can improve the user experience and safety of our platform

Bonus Points

    • Experience working with User-Generated Content or a Trust & Safety team.
    • Experience with TypeScript, Firebase, or Google Cloud Platform.

Fizz
Palo Alto, CA
What is Fizz
Fizz is a social app that allows students to connect with their campus. Each Fizz community has a private and moderated feed of anonymous posts, authored by verified students, providing the most entertaining, relatable, and interesting conversations about student life.

Students can post questions, memes, polls, and chat with other verified students while maintaining control over their identity and privacy. Fizz communities prioritize safety, authenticity, and inclusion through community-based moderation.

Founded by two Stanford dropouts, Fizz is currently expanding to colleges across the US with a mission to redefine the “social network” in a time when legacy platforms lack authenticity and are filled with curated highlight reels.

What we’ve done
We first launched Fizz at Stanford in July 2021 and have since seen >95% of undergraduates join the app, half of which use Fizz every day. Since then, we have raised over $41 million from NEA, Owl Ventures, and Lightspeed, built a rock-solid engineering team with decades of experience at top tech companies, and expanded Fizz to be the dominant community platform at 200+ colleges.

Where we’re going
Our near term goal is to expand to all US universities by the end of 2024, and continue to reimagine Fizz as the most useful platform for college communities and beyond.

As a Fizz intern, you will be able to use your own experience of being a Fizz user to directly build for a product you care about. If you are proactive and driven to tackle challenging technical problems, have a passion for crafting high-quality software, and are eager to learn quickly and build new products from scratch, this internship is perfect for you. Interns will be compensated financially and work full time out of our Palo Alto office.

Responsibilities

    • Prototype, design, develop and productionize Machine Learning solutions
    • Design, develop and productionize data pipelines for solving real world ML problems
    • Keep up to date with cutting-edge research in relevant fields and adapt solutions for large scale user facing problems
    • Work with other engineers closely to integrate ML components to the product workflow
    • Work closely with senior engineers to support and iterate fast on the solutions and measure the impact

Qualifications

    • Currently enrolled in a Bachelors, Masters or Post Graduate degree in Computer Science, Statistics, Mathematics or relevant field
    • Have strong Computer Science background with academic or real world experience in Machine Learning, Natural Language Processing, Computer Vision or other related fields
    • Have theoretical understanding and academic experience in developing ML solutions approaches such as Tree models, Deep neural networks, Sequence modeling, Transformers, LLMs
    • Familiarity with PyTorch, TensorFlow or other relevant DL frameworks

Bonus Points

    • Experience working with User-Generated Content
    • Familiarity with large-scale systems and data such as Hadoop, Hive, Spark, Kafka
