Join the team as a Software Engineer for Stytch, where you'll shape the next generation of identity products.

About the job

As a Fullstack Software Engineer, you will shape the next generation of the Stytch product as we bring Stytch’s capabilities to Twilio’s full customer base, delivering secure, developer-first identity experiences. Your focus will be the onboarding and integration experience for our customers - you’ll make it fast and delightful for developers to integrate Stytch and for end users to complete authentication and authorization flows, including emerging agentic and non-human identity use cases.  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

• Design, build and own the onboarding and integration experience for our customers, including intuitive, reliable SDK APIs that make our product easy to adopt for developers.
• Partner closely with Product, Design, and Engineering leadership to shape the team’s roadmap, prioritize high-impact work, and deliver features that unlock customer value quickly.
• Build in ambiguity: break down complex authentication and identity problems, make pragmatic tradeoffs, and deliver incremental milestones to production.
• Raise the bar for the quality of the products you work on through testing, versioning, documentation, backward compatibility, and smooth migration paths.
• Improve performance, reliability, and security of client-side flows, especially those on customers’ critical paths.
• 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!
