Job summary

PlusAI, headquartered in Silicon Valley, seeks a Software Engineer or Senior Software Engineer to own the product surface on our data and simulation platforms. You will build web apps, APIs, and backend services used by autonomy engineers, operations, and external partners.

You will work across the stack—from Python services to React/TypeScript interfaces—creating reliable tools for scenario authoring, run management, and data visualization, with ownership and quality at the forefront.

Qualifications

• BS, MS, or PhD in Computer Science or a related technical field, or equivalent practical experience.
• Production fullstack experience spanning backend services and REST APIs, relational data modeling and SQL, and modern frontend development (e.g., React/TypeScript).
• Working proficiency in Python for services, libraries, and tooling
• Ability to work directly with users to turn ambiguous engineering workflows into simple, reliable interfaces
• Self-driven with a strong sense of ownership: a quick learner who is eager to take responsibility and drive projects forward end to end

Responsibilities

• Design and ship fullstack applications end to end: Python services and REST APIs, relational data modeling, asynchronous jobs, modern TypeScript frontend interfaces, deployment, testing, observability, and production reliability
• Build scenario authoring and management tools, including interactive editors for creating, parameterizing, and versioning test scenarios, and reproducible scenario libraries shared across teams
• Build interfaces for large-scale simulation and drive-log replay: launching and tracking runs, browsing results, comparing regressions across releases, and triaging failures down to individual scenarios
• Build shared application foundations — authentication, access control, multi-tenancy, and API conventions — that serve internal engineers, operations teams, and external partners from one coherent platform
• Ensure that your work is performed in accordance with the company's Quality Management System (QMS) requirements and contribute to continuous improvement efforts
