Senior Engineering Manager

As a Senior Engineering Manager in Communication Identity Domain, you will lead the engineering teams behind Porting, Hosting, and A2P Messaging. Your teams own the products that let customers bring their own numbers onto Twilio (Porting), enable existing numbers for messaging without a full port (Hosting), and register and operate compliant Application-to-Person (A2P) messaging campaigns at scale — the gateway that determines whether a customer's messages actually reach their end users' handsets. Porting and Hosting are high-value, white-glove transactions: each one touches an existing customer's live production number, or a prospective customer's number that already works elsewhere and needs to keep working seamlessly through the transition. That makes operational maturity a core part of the value we deliver — precise execution, clear communication, and dependable outcomes are what earn a customer's trust in the Communication Identity Domain. Delivering on that requires deep, reliable integration with a broad ecosystem of carriers, aggregators, industry registries and the expertise to orchestrate that complexity into a smooth, trustworthy experience for the customer. It also means investing in efficient, well-instrumented Ops Tooling that gives your team and our internal support organizations clear visibility into every port, hosting activation, and campaign — so issues are caught and resolved quickly, and operational excellence scales with the business. You will own the people strategy, delivery execution, and stakeholder relationships for a team responsible for the trust-building work of moving and activating phone numbers for existing and prospective customers.

You will be expected to champion AI-driven development practices, ensuring your engineers adopt LLMs and agentic tools to accelerate delivery, improve quality, and stay at the forefront of modern software engineering. Your mission is to build a high-performing team that consistently ships reliable, customer-obsessed products - while balancing the competing demands of external product commitments, internal platform obligations, and operational tooling investments.
