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:

• 3+ years of experience as a fullstack engineer delivering customer-facing web products in production using modern frontend technologies (Next.js experience is a must)

• Experience developing and maintaining complex web applications and/or public-facing web SDKs.

• Experience building developer-first APIs and tools, with a focus on integration experience.

• Proven ability to ship high-quality, reliable software that runs across browsers and environments.

• Excellent written and verbal communication skills; comfortable writing design docs and leading technical discussions.

• Bachelor’s degree in Computer Science or equivalent practical experience.

• Schedule: ability to work non-standard, on-call rotation weekend and holiday hours.

Desired:

• Experience owning or contributing to open-source libraries or SDKs.

• Familiarity with authentication, identity, security, or fraud-adjacent client-side flows.

• Experience supporting public SDKs: release automation, semantic versioning, deprecations, and long-term maintenance.

• Interest in emerging identity patterns, including agentic/non-human identity and new auth workflows.
