Original job description

See yourself at Twilio

Join the team as Twilio's next Staff Mobile Software Engineer for Stytch, where you'll shape the next generation of identity and fraud prevention products.

About the job

We are currently building our talent pipeline with qualified candidates for future openings in this position. This position is needed to help scale Stytch’s core identity and fraud products as we bring Stytch capabilities to Twilio’s full customer base, delivering secure, developer-first identity and fraud prevention experiences. You’ll build mobile SDK products that power authentication, fraud detection and prevention as well as emerging agentic identity use cases. You’ll partner closely with product and engineering leadership to design and deliver high-impact customer-facing 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

In this role, you’ll:

Build and own the mobile SDKs for Stytch’s identity and fraud detection platforms on Twilio - go deep on device internals for complex signal collection to improve identification of bad actors and ship new SDK surfaces powering core authentication flows, including agenting and non-human identity use cases.
Partner with Product and Engineering leadership to set direction, translate customer needs into product capabilities, 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 design developer experiences that delight our customers.
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:

6+ years of professional mobile engineering experience, with deep experience in designing, building and maintaining mobile applications.
Android development experience, fluent in Kotlin or Java.
Expertise in mobile development ecosystems, frameworks, 3rd party libraries.
Deep understanding of software engineering best practices, including monitoring, observability, and building maintainable systems.
Experience making high-impact technical decisions and leading technical initiatives.
A proven track record of driving technical excellence while keeping customer needs at the center of your work.
Deep understanding of software engineering best practices, including monitoring, observability, and building for the long term.
Exceptional communication and collaboration skills, with the ability to influence and align stakeholders.
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

iOS development experience.
Familiarity with Kotlin Multiplatform, C/C++, Swift or Go.
Experience building developer tools or SDKs.
Builder at heart. Through a hobby or your profession, you are passionate about being hands on and seeing your work come to life.

Location

This role will be remote and based in Ontario, British Columbia or Alberta, Canada.

Travel

We prioritize connection and opportunities to build relationships with our customers and each other. For this role, you may be required to travel occasionally to participate in project or team in-person meetings.

What We Offer

Working at Twilio offers many benefits, including competitive pay, generous time off, ample parental and wellness leave, healthcare, a retirement savings program, and much more. Offerings vary by location. Based on role, employees may also be eligible for additional compensation and benefits, including but not limited to incentive programs, commissions, equity grants, health and wellness benefits, retirement contributions, and paid time off.

The estimated pay ranges for this role are as follows:

- $160,320 - $200,400.00
- Target Bonus Percentage 10%

The successful candidate’s starting salary will be determined based on permissible, non-discriminatory factors such as skills, experience, and geographic location.
