ML Engineer

Who we are

Our mission at Sourcegraph is to make it so that everyone can code, not just ~0.1% of the population. 

We are transforming how the world’s most important companies build software by industrializing development with AI. Today, most professional developers spend a disproportionate amount of time understanding code and performing repetitive, low-level tasks—leaving less time for innovation and meaningful impact.

We’re changing that. Sourcegraph brings AI-powered search and agents to the enterprise, helping teams automate the mundane and amplify what developers do best— solving hard problems and creating great products.

Here’s how we’re making a difference:

• Accelerating developers with AI agents that deliver insights and precision—enabling 5x faster test creation, 30% increase in merge requests, and saving 20 minutes per developer daily.
• Automating repetitive tasks, from remediating vulnerabilities (saving teams 1,000+ hours annually) to speeding up migrations that would take years to months. 
• Enabling innovation by addressing complex problems like automated bug triage, vulnerability detection, and AI-driven code reviews seamlessly integrated into workflows.

Trusted by 7/10 top software companies by market cap, 4/6 top US banks and many of the companies leading global innovation, like Stripe, Indeed, Tesla, and 1Password, and with $225M in funding from investors like a16z, Sequoia, and Redpoint, we are building the tools that will define the next era of enterprise software development.

If you’re passionate about solving the hardest problems in software and shaping the future of technology, join us. Let’s build something extraordinary together.

Hours & location

🌎 While we hire almost anywhere in the world, we have office hubs in select locations and expect this person to reside in the San Francisco Bay Area to be able to work from our office for several days per week.

Required locations:

• San Francisco, CA

We do not subscribe to “I do my best work when I work 40 hours a week.”  People we hire at Sourcegraph believe that building outstanding things means working very hard — smarter and more hours than the competition.

Why this job is exciting

Many companies are trying, but Sourcegraph is uniquely differentiated by our rich code intelligence data and powerful code search platform. In the world of prompting LLMs, context is everything, and Sourcegraph’s context is simply the best you can get: IDE-quality, global-scale, and served lightning fast. Our code intelligence, married with modern AI, is already providing a remarkable alpha experience, and you can help us unlock its full potential.

We are looking for an experienced full stack ML engineer with demonstrated industry experience in productionizing large scale ML models in industrial settings. And if you happen to have an entrepreneurial streak, you’re in luck:  We have an enterprise distribution pipeline, so whatever you build can be deployed straight to enterprise customers with some of the largest code bases in the world, without all the go-to-market hassle you’d encounter in a startup.
