Description

Robert Half is hiring! We are looking for a Principal Software Engineer to lead the design and delivery of modern AI-driven software solutions. This role combines hands-on engineering with technical leadership across backend services, frontend applications, and intelligent workflow development. The ideal candidate brings deep full-stack expertise, a strong product mindset, and the ability to guide scalable systems from concept through production.

Responsibilities:

Lead complete product delivery efforts, from technical planning and architecture through implementation, testing, and long-term support.
Create and refine agentic AI workflows that support business goals and integrate effectively with broader application ecosystems.
Build, enhance, and support scalable server-side applications using Python frameworks such as Django, Flask, or FastAPI, or Node.js frameworks including Express or NestJS.
Develop robust RESTful and GraphQL interfaces that enable reliable communication between platforms, services, and user-facing applications.
Implement and improve React-based frontend features with a focus on usability, responsiveness, and smooth integration with backend systems.
Architect and maintain microservices and distributed application components to support performance, resilience, and future growth.
Improve system efficiency by tuning application behavior, streamlining database interactions, and optimizing cloud infrastructure usage.
Apply strong security standards by implementing access controls, authentication mechanisms, and authorization practices across the platform.
Oversee automated delivery processes and container-based deployments using CI/CD pipelines, Docker, and related engineering tools.
Partner with product, design, and DevOps teams to resolve production issues, maintain cloud-based services, and deliver high-quality software outcomes.

Requirements

At least 8 years of experience delivering software solutions in production environments.
Strong development expertise in Python or Node.js, with the ability to build maintainable and scalable applications.
Proven experience creating frontend applications with React in a full-stack development setting.
Hands-on knowledge of relational databases such as PostgreSQL or MySQL and/or NoSQL platforms such as MongoDB or DynamoDB.
Solid understanding of API design principles, including RESTful services, and experience with asynchronous programming concepts.
Proficiency with Git and team-based development practices in collaborative engineering environments.
Strong analytical thinking and problem-solving skills, with the ability to balance multiple priorities effectively.
Commitment to producing clear, maintainable, and well-documented code while working effectively with cross-functional teams.
