Twitter is what’s happening and what people are talking about right now. For us, life's not about a job, it's about purpose. We believe real change starts with conversation. Here, your voice matters. Come as you are and together we'll do what's right (not what's easy) to serve the public conversation.

Who we are

The ML Infrastructure team’s mission is to provide Twitter’s ML Engineers with the orchestration tools and compute capacity to reliably run state-of-the-art ML experiments. We provide this capability through managed Kubeflow clusters built on top of Google Kubernetes Engine, running in Google Cloud Platform. We partner with our sister teams within Cortex Platform to provide an end-to-end ML experimentation platform experience.

Cortex Platform 

Cortex Platform empowers internal teams to efficiently leverage ML by providing a platform and by unifying, educating, and advancing the state of the art in ML technologies within Twitter. We win when our customers win by helping our users stay informed, share and discuss what matters; by serving the public conversation. We’re building an AI-first company and every major initiative is increasingly dependent on the successful application of machine learning. Cortex is at the nexus of this evolution.

We are building one of the strongest machine learning platforms in the world by marrying the latest ML industry practices with engineering excellence and the need to perform at Twitter scale. Our customers are all the ML engineers at Twitter and our goal is to provide a unified tooling ecosystem that allows these engineers to focus on what they are good at, building ML models with novel approaches, and abstracting away the complexities of bringing these models into a production environment.

What Success Looks like

We look for someone who can lead a team of diverse, smart, and driven engineers distributed across multiple locations. We need leaders who take an active role in shaping the future of Twitter engineering while embodying our principles. A successful engineering manager will:
 

• Own your team’s deliverables and ensure we develop scalable, highly-available infrastructure that enables product engineers to experiment and rapidly iterate on products that delight our users and customers. 

• Take responsibility for the team’s short-term and long-term strategy. Define the team's roadmap, success metrics (OKRs), and priorities in close collaboration with product management, other engineering teams and multi-functional partners.

• Maintain a balance between building sustainable, high-impact projects and shipping things quickly.

• Lead a team of talented machine learning software engineers who like to ship code and tackle hard engineering problems.

• Build cohesive, high-functioning teams that thrive in a culture of trust, respect, and inclusion.

• Balance autonomy with guidance by giving your team the tools, context, confidence, and motivation to make decisions effectively and independently.

• Have the technical capacity to partner with tech leads and be comfortable diving into the fray to help drive resolution in the case of incidents.

We care deeply about:

• Engineering excellence such as good design abstractions, API stability, unit testing, leading best practices for other engineers to follow, and solid documentation.

• Staying abreast and compatible with a quickly shifting technology landscape for ML platform components and related open source solutions.

• Creating the best ML Platform environment for Twitter that provides an exceptional developer experience for our engineering customers.

• Encouraging engineering creativity and innovative solutions

Our Current projects include:

• Establishing Kubeflow as a managed offering at Twitter

• Enabling and sustaining GCP Infra/Platform components for broader use in Cortex platform; e.g. AI Platform, Dataflow, Data Proc, etc.

• Improving Operations of essential ML Platform services

  • Hosted notebooks

  • ML Training Service

  • Continuous model training and deployment
