About the job

This position is needed to drive innovation and the development of cutting-edge products that serve developers, builders, and operators within Twilio’s Data & Observability Substrate organization.

This is a hands-on, builder-focused engineering role that bridges Product, Design, and Engineering to develop, evaluate, and maintain scalable, low-latency, ML-based systems for real-time applications. 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.
