Description
At Twilio, we're shaping the future of communications, all from the comfort of our homes. We deliver innovative solutions to hundreds of thousands of businesses and empower millions of developers worldwide to craft personalized customer experiences.
As a Software Engineer (L3), 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:
- Contribute significantly to 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.
- 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 in the team, 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 junior and mid-level engineers.
- Foster a culture of technical curiosity, ownership, and continuous learning.
- Identify and mitigate technical risks early, ranging from scalability bottlenecks to security vulnerabilities.
- Lead the team through complex production incidents with a focus on long-term remediation.
- Articulate technical designs and system trade-offs clearly to your team and cross-functional partners through high-quality design documents, RFCs, and collaborative discussions.
Qualifications:
- 5+ years of experience designing and developing highly available, high-scale, secure, mission-critical cloud-native enterprise distributed systems.
- Strong proficiency in Java or Python with solid knowledge of AWS ecosystems (Lambda, EKS, DynamoDB, Kafka).
- Cloud-Native Architecture: Hands-on experience with cloud-native infrastructure (AWS preferred), microservices patterns, and building highly resilient systems.
- AI-Augmented Development: Practical experience using AI tools (e.g., Copilot, Claude, Cursor) to accelerate software delivery.
- API Design: Experience building and maintaining high-volume public-facing APIs with a focus on developer experience.
- Data Proficiency: Experience with high-throughput data processing and storage solutions (SQL/NoSQL, Redis, Kafka, or Spark).
- Infrastructure as Code: Familiarity with Kubernetes, Terraform, and modern CI/CD paradigms.
- Collaboration & Influence: Demonstrated ability to influence technical decisions within your team through strong communication and technical credibility.
Location: This role will be remote, and based in India.
Travel: You may be required to travel occasionally to participate in project or team in-person meetings.
What We Offer: Working at Twilio offers many benefits, including competitive pay, generous time off, ample parental and wellness leave, healthcare, a retirement savings program, and much more.
