About The Position

About this Opportunity: The Principal Software Engineer (IC6) leads the design, development, and evolution of Orion’s modern cloud-native technology stack. This role architects end-to-end systems, sets and drives engineering standards, identifies long-term platform investments, and leverages deep expertise in AWS, serverless patterns, distributed systems, JavaScript/TypeScript, React, and modern application development. Operating with substantial autonomy, the Principal Engineer tackles Orion’s most complex technical challenges, charts the course for major engineering initiatives, and ensures solutions are reliable, scalable, secure, cost-efficient, and aligned to business outcomes. For Internal and External Candidates: Candidates must work in-office at one of the following locations for at least 3 days per week: Jacksonville, FL. In this role, you'll get to: Architecture & Systems Design Architect and implement large-scale, fully serverless applications using AWS Lambda, API Gateway, CloudFront, EventBridge, SQS/SNS, S3, and RDS. Define the architectural vision for cloud-native, event-driven systems across Orion. Lead design for new platforms, subsystems, and cross-cutting capabilities that support Orion’s growth and scale. Build and maintain infrastructure-as-code and CI/CD pipelines that support rapid, consistent deployment. Technical Leadership Serve as Orion’s top technical expert in AWS architecture and serverless engineering. Provide guidance, mentorship, and direction to engineers, senior engineers, and tech leads. Lead design reviews, complex debugging efforts, and operational excellence initiatives. Drive adoption of new AWS services, modern distributed system patterns, and emerging technologies—including generative and agentic AI. Partner with Product, Security, DevOps, and business stakeholders to ensure technical decisions support Orion’s strategic goals. Quality, Security & Reliability Champion secure coding practices, system hardening, and proactive risk mitigation. Build performant, resilient, scalable systems that self-heal and optimize cost. Create and enforce testing strategies, including integrated and automated testing approaches. Diagnose and solve high-severity issues across any layer of the stack—front-end, back-end, database, networking, or infrastructure. Collaboration & Influence Shape the engineering culture by promoting best practices, simplification, and continuous improvement. Influence roadmaps and technology direction through data, experience, and clear communication. Serve as a trusted advisor across engineering teams and to senior leadership. Build strong cross-functional relationships to drive work that impacts multiple areas of the business. Mindset & Operating Approach Independently define methods, strategies, and technical approaches for novel or ambiguous initiatives. Balance creativity and discipline to build solutions that deliver outsized impact. Maintain a continuous learning practice to stay ahead of rapidly evolving cloud engineering trends.
