See yourself at Twilio

Join the team as Twilio’s next Senior Infrastructure Engineer.

About the job

This position is needed to build and scale Stytch’s core product as we bring Stytch capabilities to Twilio’s full customer base, delivering secure, developer-first identity experiences.

Join the Stytch team at Twilio to shape the next generation of identity products. You’ll design and build infrastructure that power authentication, authorization, and emerging agentic and non-human identity use cases. You’ll partner closely with product and engineering leadership to set direction, deliver high-impact features, and evolve our platform for Twilio scale. This is a rare chance to operate like a startup within Twilio: you’ll work in a high-ownership environment with startup speed, backed by Twilio’s reach and scale.

Responsibilities

• Build and own the infrastructure and platform capabilities that power Stytch’s identity platform as it scales across Twilio—ensuring security, reliability, and performance for every customer.
• Design, implement, and operate scalable cloud infrastructure (AWS/EKS, ECS, networking, data stores), balancing uptime, cost, and developer velocity.
• Partner closely with Product and Engineering leadership to set infrastructure direction, translate platform needs into technical plans, and deliver high-impact roadmap work.
• Collaborate across Twilio and Stytch teams to align on architecture, integrate platform capabilities, and unblock cross-team initiatives.
• Operate with deep technical ownership: author design docs, drive key technical decisions, review code, and stay close to the systems you ship.
• Build in ambiguity—break down complex problems, make pragmatic tradeoffs, and adopt new technologies or strategies when they improve outcomes.
• Improve production quality and resilience through strong observability, incident response, automated remediation, and continuous reliability engineering.
• Make developers’ lives easier by building self-service tooling, safer deployment patterns, and reliable platform primitives that accelerate product teams.
• Mentor and support other engineers through pairing, feedback, and knowledge-sharing, helping raise the team’s technical bar and culture.

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!
