Senior Software Engineer

Senior Software Engineer

The Senior Software Engineer 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, C#, SQL 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. As we continue to evolve and live our Orion values, we are looking for someone to grow with us.

Candidates must work in-office at one of the following locations for at least 3 days per week: Omaha, NE.

It is anticipated that an incumbent in this role will work as a Hybrid employee, with three (3) or more days each week required on-site at one of the listed office locations.

Candidates should be located within a commutable distance to an office. Internal candidates currently aligned to an Orion office location may be given preference; however, internal candidates with varying work arrangements may be considered based on experience and business needs. Work location is subject to change based on business needs.

In this role, you'll get to:

• 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
• 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.
• 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
• 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
• 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
• Operate with a platform-owner mindset—thinking holistically about reliability, scale, and long-term maintainability

We're looking for talent who:

• Has mastery of C#/.NET ecosystem
• Has strong understanding of browser capabilities, web performance, and front-end architecture
• Has advanced SQL and relational database expertise
• Has knowledge of data lakes and distributed data pipeline technologies
• Has expertise across AWS (Lambda, API Gateway, CloudFront, SQS, SNS, SES, EventBridge, S3, RDS, Bedrock)
• Has strong understanding of OAuth2, OpenID Connect, cryptography, and security protocols
• Has mastery of git workflows, CI/CD pipelines, IaC best practices, and SDLC processes
• Has broad architectural pattern knowledge (DDD, CQRS, SOLID, event-driven patterns)
• Has exceptional debugging and problem-solving skills across the full stack
• Tackles high-impact, highly ambiguous problems with no blueprint
• Defines technical frameworks, patterns, and decision structures for other engineers to follow
• Solutions directly influence Orion's long-term scalability, reliability, and competitive advantage
• Builds influence networks across teams and guides engineering direction at scale
• Operates with full independence on new, critical, or technically undefined initiatives
• May indirectly lead engineers or project teams through influence and technical direction
• Determines architecture, technical strategies, and methods for complex initiatives
• Has a minimum of 10+ years of progressive software engineering experience
• Has demonstrated mastery architecting and building in AWS
• Has AWS Solutions Architect certification (or equivalent experience) strongly preferred
• Owns and manages relationships with stakeholders directly and works effectively with people at all levels in an organization
