Twitter is what’s happening in the world and what people are talking about right now. From breaking news and entertainment to sports, politics, and everyday interests, see every side of the story. Join the open conversation, and collaborate with creative and curious people across the globe.  “The whole world is watching Twitter. You don't go a day without hearing about Twitter, how it’s used as the fastest way to send a message to the world in an instant, how it carries some of the most important commentary and conversations, how it mobilizes people into action. That's powerful, it's valuable, it's fundamental.” - Jack Dorsey, CEO

Who We Are

The Consumer Engineering organization’s mission is to develop experiences that serve the public conversation and delight our hundreds of millions of customers around the world. We’re responsible for timelines, recommendations, and search systems that allow customers to discover and connect with the most relevant content. Tweet authoring, direct messages, Fleets, Spaces, and many other new experiences for content creators live within the Consumer organization. Mobile experiences are central to everything we do.

Consumer is a rapidly growing organization with both existing and brand new products to support, unsolved technical challenges, and hundreds of millions of tweets and engagements each day. We are looking for experts in iOS and Android to help us build it all.

What You’ll Do

Principal engineers at Twitter operate with company-wide impact. In this role, you’ll report to the VP of Engineering and be responsible for setting technical direction, shaping our engineering culture, identifying and adopting best practices, designing effective partnerships, mentoring and coaching our technical leads, and more. You will be a technical leader with substantial autonomy who will work to enable effective collaboration, high velocity execution, and technical excellence across the company.

You will focus on mobile but also work at all layers of the stack and partner closely with technical leaders and senior management across all of engineering, data science, research, product, and design. You will help our codebase stay ahead of the curve of the constantly evolving development ecosystem and will ensure that feature development at Twitter is both fast and fun.

You will be responsible for guiding the organization as we rapidly expand our mobile team and architecture. While you will certainly spend plenty of time contributing directly to the codebase, you will also focus on using your creativity, problem solving, and technical skills to empower the engineers around you to do their best work.

You are an experienced IC engineering leader looking to make Twitter one of the best mobile experiences out there. You care about culture, collaboration, and partnership just as much as you care about coding, architecture, and technical design. You have a strong customer focus, you are comfortable with ambiguity, you can drive alignment, and you make thoughtful data driven decisions. You care deeply about quality, are energized by partnership and collaboration, and you strive to enable others around you to excel.

Requirements:

• 10+ years of software engineering experience and 4+ years of focused mobile app development.

• Experience developing iOS and/or Android applications

• Proven experience in technical leadership roles

• Strong knowledge of web and mobile architecture

• Hands-on experience building, deploying, and scaling native iOS and/or Android applications.
