## Description

As a Principal Software Engineer for Stytch at Twilio, you will shape the next generation of identity storage, relationship tracking, and resolution. You will serve as the technical anchor for a brand new, 0-1 initiative: building an Identity Graph on the Fraud & Risk teams.

## Responsibilities

- Own the technical vision and system architecture for Identity Graph, evaluating and selecting the optimal technology stack to store complex identifiers and their relationships.

- Design, implement, and maintain high-performance, synchronous read models capable of serving identifier topologies and risk postures fast enough for real-time risk decisions.

- Build out complex data pipelines optimized for multi-cadence hydration, margin real-time dynamic events, periodic batch enrichments, and static reference data.

- Bake in strict privacy boundaries and secure PII handling from day 1.

- Partner closely with product and engineering leadership to manage expectations, set direction, and turn initial concepts into actionable plans.

- Collaborate across Twilio and Stytch teams to align on architecture, integrate platform capabilities, and unblock cross-team initiatives.

- Wrangle ambiguity and execute with a bias for action in grey areas - proactively breaking down undefined problems, making pragmatic architectural trade-offs, and helping write requirements instead of waiting for them.

- Establish strong production quality, resilience, and observability standards for a large-scale data and distributed graph platform.

- Deeply collaborate with the engineering team, prioritizing mentorship, knowledge-sharing, and pairing to elevate the team’s technical bar while actively bringing others along with you.

## Qualifications

- 8+ years of experience in designing, building, and operating high-scale, mission-critical distributed systems, graph databases, and complex data models.

- Deep hands-on expertise in a production-grade code base in a modern programming language, setting best practice coding standards, and writing high-quality code.

- Proven experience serving as a strong technical anchor, owning system architecture and vision, and leading cross-functional engineering teams through implementation.

- Exceptional ability to wrangle ambiguity and execute with a bias for action - proactively clarifying boundaries, defining scope, and turning concepts into an actionable MVP.

- Deep commitment to collaborative team dynamics and mentorship, with a track record of prioritizing bringing others along and actively raising a team's technical bar.

- Excellent written and verbal communication skills with proven ability to manage stakeholder expectations and drive technical alignment across product and engineering.

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

- Ability to work non-standard, on-call rotation weekend and holiday hours.
