Software Engineer, Sign-Up Flow Optimization

Paramount•West Hollywood, CA

About The Position

We are seeking a Software Engineer (IC2) to join the Sign-Up Flow pod. Your mission is to implement and scale the ML systems that optimize how we personalize and optimize our P+ sign-up flow and Pluto TV registration flows. You will own the development of specific features and components within our sign-up/registration flow pipelines. In this role, you will be expected to deliver autonomously on defined technical problems, ranging from bandit-based reward signals to visual optimization of the sign-up/registration flows. You will work in a high-velocity environment where visual and attention optimization are the primary goals, requiring you to balance technical quality with delivery speed.

Requirements

3+ years of experience in backend software engineering or distributed systems.
Strong proficiency in Python and experience building and scaling production APIs.
Experience with asynchronous messaging, queues, and background workers.
Solid knowledge of SQL and data modeling for high-volume metadata systems.
Proven ability to own features autonomously and deliver clean, maintainable code.

Nice To Haves

Familiarity with Cloud Architecture (GCP preferred) and containerization (Docker/Kubernetes).
Experience or strong interest in Video/Media Processing (encoding, FFmpeg, or metadata standards).
Basic knowledge of ML Integration and how to serve model outputs via APIs.
Experience working with Agentic workflows or complex service orchestration.

Responsibilities

Design and implement specific solutions for Multi-Armed Bandit (MAB) systems in the sign-up/registration flows.
Own the end-to-end implementation of defined tasks, from data ingestion to production deployment, with moderate autonomy.
Proactively identify and fix bottlenecks in team systems to improve quality, reliability, or engineering velocity.
Participate actively in design and code reviews, providing constructive feedback and ensuring high technical standards within your scope.
Set up and monitor online experiments (A/B tests and bandit rollouts) to measure the impact of presentation features on user engagement.
