See yourself at Twilio

Join the team as our next Backend Software Engineer on Twilio Segment CDP engineering team.

Who we are & why we’re hiring

Twilio powers real-time business communications and data solutions that help companies and developers worldwide build better applications and customer experiences.

Although we're headquartered in San Francisco, we have presence throughout Europe, Asia and Australia. We're on a journey to becoming a globally anti-racist, anti-oppressive, anti-bias company that actively opposes racism and all forms of oppression and bias. At Twilio, we support diversity, equity & inclusion wherever we do business. We employ thousands of Twilions worldwide, and we're looking for more builders, creators, and visionaries to help fuel our growth momentum.

About the job

Segment is a best-in-class customer data platform (CDP) designed with engineers, marketers, and product managers in mind. We’re excited to work at the cutting edge of data and artificial intelligence, such as with our AI-Assisted Suggest Mappings product. And, we move a lot of data - over 12 trillion API calls a year.

This position is needed to build and scale APIs to enable Twilio developers to unlock best-in-class personalized customer experiences through the Twilio Segment CDP products. As a Software Engineer on the team, you will collaborate closely with product management, architecture, and other engineering teams to design APIs, identify performance bottlenecks, and data models, and drive system-level improvements that enhance both developer velocity and customer experience. You’ll be expected to evaluate and communicate trade-offs between feature velocity, system stability, and technical debt, and help drive architectural decisions that ensure long-term sustainability and performance.

We iterate quickly on these products and features and learn new things daily — all while writing quality code using the latest AI tools. We work closely with product and design and solve some of the toughest engineering problems to unlock new possibilities for our customers. If you get excited by building products with high customer impact — this is the place for you.

Responsibilities

In this role, you’ll:

• Design and build robust, scalable backend systems and APIs across Segment’s data platform.
• Collaborate cross-functionally with design, product, and other engineers to define solutions that balance usability, performance, and long-term architecture.
• Communicate technical decisions clearly - articulating trade-offs, customer impact, and team alignment.
• Troubleshoot and improve system reliability, debugging issues and refining operational tooling and processes.
• Participate in an on-call rotation for our managed services
