Principal Engineer

We are seeking a Principal Engineer to join our Compliance Experiences team at Twilio. 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.

Responsibilities:

• Lead the architecture and long-term technical roadmap, transitioning legacy systems into a modern, distributed microservices architecture that supports global scale.
• Lead by example in using AI coding assistants to automate boilerplate, generate exhaustive test suites, and perform rapid prototyping.
• Drive technical excellence across multiple teams, making critical architectural decisions that balance rapid feature innovation with world-class reliability and security.
• Partner with Product Managers to translate complex global telecommunications regulations and customer needs into elegant, developer-first APIs and application workflows.
• Mentor and uplift senior and staff engineers, fostering a culture of technical curiosity, ownership, and continuous learning.
• 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.
• Communicate complex technical strategies to both executive leadership and engineering teams through high-quality design documents, RFCs, and presentations.

Qualifications:

• 16+ years of experience designing and developing highly available, high-scale, secure, mission-critical cloud-native enterprise distributed systems.
• Expert proficiency in Java or Go, with deep knowledge of AWS ecosystems (Lambda, EKS, DynamoDB, Kafka).
• Architectural mastery: deep experience with cloud-native infrastructure (AWS preferred), microservices patterns, and designing 'five-nines' (99.999%) resilient systems.
• AI-native workflow: demonstrated experience using AI tools to significantly accelerate software delivery.
• 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).
• Infrastructure as Code: proficiency with Kubernetes, Terraform, and modern CI/CD paradigms.
• Leadership: proven ability to influence technical strategy across multiple teams and organizational boundaries without direct authority.
