See yourself at Twilio


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


About the job


As a Staff Backend Software Engineer you will help scale Stytch’s core product as we bring Stytch capabilities to Twilio’s full customer base, delivering secure, developer-first identity experiences. You’ll design and lead implementation of backend systems 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’s 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 backend product capabilities for Stytch’s identity platform on Twilio—shipping new API surfaces and core authentication flows, including agentic and non-human identity use cases.

  • Design, implement, and maintain scalable, reliable distributed services, optimizing for security, latency, and developer experience.

  • Partner with Product and Engineering leadership to set direction, translate customer needs into technical plans, and deliver high-impact roadmap features.

  • 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 and remediation.

  • 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!


*Required:



  • 7+ years experience in designing, building and operating high-scale, mission critical cloud based production systems.

  • Familiarity with a production-grade code base in a modern programming language, applying best practice coding standards and writing high quality code.

  • Experience designing technical services and leading teams through implementation.

  • Extensive experience with RESTful API design and development.

  • Bachelor’s degree in Computer Science or related industry experience.

  • Excellent written and verbal communication skills.

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


Desired:



  • Familiarity with Go, Kubernetes, and DynamoDB

  • Experience building developer tools and/or internal platforms that improve velocity and reliability.

  • Experience designing and building highly reliable back end systems

  • Builder at heart. Through a hobby or your profession, you are passionate about being hands on and seeing your work come to life.
