About the role

Key responsibilities & impact

Own the technical direction and roadmap for the member referral platform across the full stack — from frontend experiences to backend services and data pipelines.
Scale incentive and referral systems to handle growing member volume and complexity without degrading conversion or user experience.
Integrate ML model outputs (for example, propensity scores, personalized offers, and targeting signals) into referral surfaces to improve effectiveness.
Design, instrument, and analyze A/B experiments; work with data science to close the feedback loop between model outputs and product outcomes.
Partner with product, design, and analytics to define what to build and why, balancing short-term wins with long-term platform leverage.
Raise the engineering bar by driving code quality, system design standards, observability, and technical decision-making on the team.

Requirements

What you’ll need

Bachelor’s degree (or foreign equivalent) in Computer Science, Engineering, or a related technical field.
4+ years of professional software engineering experience, including meaningful time working on production systems at scale.
Hands-on experience building and operating full-stack applications (for example, using React/React Native on the frontend and Node.js/TypeScript or similar on the backend).
Incentive & growth experience — a track record of designing or evolving systems that measurably shift user behavior through incentives, rewards, or social mechanics.
Personalization at scale — experience operationalizing ML model pipelines, model serving, A/B testing infrastructure, and feedback loops that connect model performance to product outcomes.
Full-stack depth — strong skills across technologies such as React, React Native, TypeScript, NestJS, GraphQL, Node.js, relational and non-relational databases, Docker, Kubernetes, AWS, and Redis. We don’t expect a perfect match on every technology, but you should be fluent in most.
Staff-level leadership — you’ve set technical direction for a team, influenced cross-functional roadmaps, and made architectural decisions that have held up over time.
