About Us: 
Bluesky's mission is to transition the social web from platforms to protocols. We're building a federated social network where users have more power. Our team has decades of combined experience building distributed applications.

Role Overview:
As a Senior Machine Learning Engineer at Bluesky, you will design, develop, and maintain machine learning systems for various parts of our stack. You will work on systems that directly impact the user's experience on the network, whether through content recommendation, search, spam detection, or automated labeling. Your work will augment the team's abilities to make the network a good place for all our users.

Key Responsibilities:
  • Design and implement machine learning models to improve personalized content recommendations, search, spam detection, topic labeling, and more.
  • Work with the giant open dataset, the Bluesky social graph, and its content.
  • Run machine learning tests and experiments, documenting findings and results for future iterations.
  • Ensure algorithms deliver accurate user recommendations and optimized experiences.
  • Train, retrain, and monitor machine learning systems to maintain model effectiveness.
  • Operate and run machine learning systems at scale in production environments..

Required Qualifications:
  • 3+ years of recent experience in machine learning or data science roles, with a focus on recommendations and search.
  • Proficiency in Python and experience with PyTorch and related modules.
  • Willingness and a knack for rapid experimentation.
  • Familiarity with data structures, data modeling, and software architecture.
  • Experience with high-scale technologies 

We're especially excited if you:
  • Experience in recommendation systems, user behavior modeling, and social graph analysis.
  • Familiar or proficient with Golang, our ML code interfaces with it heavily.
  • Have experience with Ray, BigQuery, and Postgres.
  • Ability to extend and optimize existing machine learning libraries and frameworks.
  • Strong communication skills and a collaborative mindset for working with cross-functional teams.

We’re a fully remote team, but an overlap of working hours with PST is required, and for this role, proximity and willingness to travel to Seattle is a plus. Please note, there may be an on-site component to these interviews. We offer health, dental, and vision insurance. If you want to work with an excellent team and help define the future of social, we encourage you to apply.

Additional notes:
  • The anticipated base salary range for this position is $221,000 - $405,000 USD, excluding equity. Equity will be considered in the total compensation package. Final base salary for this role will be based on the individual’s geographic location, as well as experience level, skill set, training, licenses and certifications.

What you need to know about the Boston Tech Scene

Boston is a powerhouse for technology innovation thanks to world-class research universities like MIT and Harvard and a robust pipeline of venture capital investment. Host to the first telephone call and one of the first general-purpose computers ever put into use, Boston is now a hub for biotechnology, robotics and artificial intelligence — though it’s also home to several B2B software giants. So it’s no surprise that the city consistently ranks among the greatest startup ecosystems in the world.

Key Facts About Boston Tech

  • Number of Tech Workers: 269,000; 9.4% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Thermo Fisher Scientific, Toast, Klaviyo, HubSpot, DraftKings
  • Key Industries: Artificial intelligence, biotechnology, robotics, software, aerospace
  • Funding Landscape: $15.7 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Summit Partners, Volition Capital, Bain Capital Ventures, MassVentures, Highland Capital Partners
  • Research Centers and Universities: MIT, Harvard University, Boston College, Tufts University, Boston University, Northeastern University, Smithsonian Astrophysical Observatory, National Bureau of Economic Research, Broad Institute, Lowell Center for Space Science & Technology, National Emerging Infectious Diseases Laboratories
