. See yourself at Twilio Join the team as Twilio’s next Senior Engineering Manager. About the job 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.

BE AN OWNER: Take full accountability for your team’s operational excellence, including system reliability, incident response, on-call health, and security posture. Make high-judgment calls that balance speed, quality, and risk. WEAR THE CUSTOMER’S SHOES: Serve two customer bases with equal rigor. For external customers, partner with Product Management to ensure communication identity workflows are seamless and developer-friendly.

For internal customers, proactively engage with dependent engineering teams to understand their needs, gather feedback on your team’s APIs and Ops Tooling, and ensure your platform enables them to move faster.

Balance requests from multiple stakeholders-Product Management, internal engineering teams, and operations-with a clear framework for saying “no” to protect focus.

Ensure resources are aligned to the highest-impact work across all three pillars. WRITE IT DOWN: Communicate team strategy, progress, and risks clearly and consistently to engineering leadership and cross-functional partners. Author team plans, post-mortems, and decision documents that create transparency and alignment. BUILD BRIDGES: Act as the primary point of contact between the Communication Identity Domain and its stakeholders.

Manage relationships with Product Management, external-facing teams, and internal engineering teams that depend on your services and Ops Tooling. Proactively communicate roadmap plans, surface trade-offs, negotiate priorities, and ensure stakeholders have clear visibility into what y
