Staff Software Engineer

The Compliance Experiences team sits at the heart of the Twilio platform, owning two critical domains: Phone Numbers and Compliance (KYC). In 2026, 'getting a phone number' is no longer a simple API call; it requires sophisticated orchestration across global phone number inventory, real-time identity verification, regulatory compliance, and operational tooling at massive scale. Twilio’s KYC Platform, the gateway to accessing all of Twilio’s communication APIs, enables customers to securely provision and operate communication services globally while navigating complex, constantly evolving regulatory requirements.

As a Staff Software Engineer (P4), you will be a key technical leader for a platform that processes millions of requests. You will build innovative solutions while working closely with Twilio partners to ensure alignment. You will lead the technical design and influence the strategic direction that shapes Twilio’s compliance footprint. You will collaborate with cross functional teams and stakeholders across Twilio who rely on your team's APIs, services, and tooling to operate efficiently. You will embrace AI-driven development workflows, using LLMs and agentic tools to accelerate code generation, improve test coverage, and translate complex regulatory requirements into executable logic. Your mission is to turn ambitious designs into production-grade features.

• 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 (GitHub Copilot, Anthropic Claude, or internal LLMs) 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. Foster 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.

• 12+ 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).
• Deep experience with cloud-native infrastructure (AWS preferred), microservices patterns, and designing 'five-nines' (99.999%) resilient systems.
• 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.
• A track record of building and maintaining high-volume public-facing APIs that focus on exceptional developer experience.
• Experience with high-throughput data processing and storage solutions (SQL/NoSQL, Redis, Kafka, or Spark).
• Proficiency with Kubernetes, Terraform, and modern CI/CD paradigms.
• Proven ability to influence technical strategy across multiple teams and organizational boundaries without direct authority.

• Experience with telephony protocols, local number porting (LNP), or global regulatory compliance frameworks.
• Experience building 'internal platforms' that enable other developer teams to move faster.
• Experience building or integrating AI agents into internal developer platforms or automated ops workflows.
