About the job

The Phone Numbers Platform is the heartbeat of Twilio. In 2026, "getting a phone number" is no longer a simple API call; it is a sophisticated orchestration of global inventory, real-time identity verification (KYC), and automated regulatory compliance.

As a Principal Engineer (P5), you will own the technical strategy for a platform that processes millions of requests. You will be expected to pioneer AI-driven development workflows using LLMs and agentic agents to accelerate code generation, automate architectural reviews, and synthesize complex global telecommunications regulations into executable logic. Your mission is to collapse the distance between a great idea and a production ready feature.

Responsibilities

In this role, you’ll:

• DRAW THE OWL: Lead the architecture and long-term technical roadmap for the Phone Numbers Platform, transitioning legacy systems into a modern, distributed microservices architecture that supports global scale.
• ACCELERATE WITH AI: Lead by example in using AI coding assistants (GitHub Copilot, Anthropic Claude, or internal LLMs) to automate boilerplate, generate exhaustive test suites, and perform rapid prototyping. You will be measured on your ability to amplify your own output and the team's velocity through AI augmentation.
• BE AN OWNER: Drive technical excellence across multiple teams, making critical architectural decisions that balance rapid feature innovation with world-class reliability and security.
• WEAR THE CUSTOMER’S SHOES: Partner with Product Managers to translate complex global telecommunications regulations and customer needs into elegant, developer-first APIs and application workflows.
• EMPOWER OTHERS: Mentor and uplift senior and staff engineers. Foster a culture of technical curiosity, ownership, and continuous learning. Teach the team how to move from "writing code" to "reviewing and orchestrating AI-generated logic" without sacrificing security or quality.
• RUTHLESSLY PRIORITIZE: Identify and mitigate technical risks early, ranging from scalability bottlenecks to security vulnerabilities and lead the team through complex production incidents with a focus on long-term remediation.
• WRITE IT DOWN: Communicate complex technical strategies to both executive leadership and engineering teams through high-quality design documents, RFCs, and presentations.

• AI-Native Workflow: Demonstrated experience using AI tools to significantly accelerate software delivery. You should be comfortable discussing how you use LLMs for architectural brainstorming, debugging, and code synthesis.
• API Excellence: A track record of building and maintaining high-volume public-facing APIs that focus on exceptional developer experience.
• Data Savvy: Experience with high-throughput data processing and storage solutions (SQL/NoSQL, Redis, Kafka, or Spark).

You will lead rapid research-to-production cycles that translate business ideas into solutions for complex problems—such as streaming anomaly detection, recommendation systems, predictive modeling, and agentic AI frameworks—with the goal of delivering personalized customer experiences.

You will collaborate closely with a cross-functional team of engineers, architects, product managers, UI/UX designers, and ML/data science partners to deliver robust, reliable solutions that power customer success.

Responsibilities

In this role, you’ll:

• Partner with product, UX, and technical stakeholders to analyze business problems, clarify requirements, define scope, and translate them into measurable ML problem statements.
• Design, implement, and maintain scalable, enterprise-grade ML solutions in production.
• Build reproducible ML workflows for data preparation, training, evaluation, and inference using modern orchestration and MLOps tooling.
• Implement monitoring and evaluation frameworks to continuously improve data quality, model performance, latency, and cost through feedback loops.
• Partner cross-functionally with Product, Data Science/ML, Engineering, and Security to deliver resilient, scalable, and compliant ML-powered services.
• Demonstrate end-to-end systems understanding and articulate the “why” behind model and system design choices.
• Own operational excellence: SLAs, on-call, incident response, customer feedback triage, and blameless post-mortems.
• Drive engineering excellence via AI-assisted SDLC, code reviews, automated testing, MLOps best practices, knowledge-sharing, and mentoring.
• Actively adopt AI-assisted practices to improve implementation and collaboration efficiency.

Qualifications 

Twilio values diverse experiences from all kinds of industries, and we encourage everyone who meets the required qualifications to apply. If your career is just starting or hasn't followed a traditional path, don't let that stop you from considering Twilio. We are always looking for people who will bring something new to the table!
