Our engineering teams build enterprise-grade, revenue-generating products at the intersection of cloud, data, analytics, and emerging AI technologies. If you’re excited about building sophisticated software that makes a real-world impact on healthcare, this is the place to do it.

You will make an impact:

As a Principal Full Stack Software Engineer, you will be a technical leader within the elluminate Product Development team. You’ll help design and build the core services and user experiences of a next-generation clinical data and analytics platform—while influencing architecture, engineering standards, and technical direction.

This role is ideal for an experienced engineer who enjoys hands-on development, mentoring others, and bringing modern capabilities—including AI-assisted and agentic workflows—into production-grade systems.

Your day to day:

• Design, develop, test, and deploy scalable, secure, and highly interactive web applications
• Own and evolve core platform modules, from concept through release and support
• Influence application and system architecture with a focus on performance, reliability, security, and maintainability
• Lead by example through clean, well-tested code, thoughtful design reviews, and pragmatic technical decisions
• Collaborate closely with Product Management, QA, and other engineers throughout the SDLC
• Provide technical mentorship and guidance to other engineers on the team
• Diagnoses and resolves complex production issues across distributed systems
• Ensure solutions meet eClinical Solutions quality standards and applicable industry regulations
• Contribute to technical documentation including design specs, acceptance criteria, and release notes

AI & Modern Engineering Focus

We’re actively incorporating AI-powered capabilities into our platform, and you’ll help shape how this is done responsibly and effectively in an enterprise environment. This includes:

• Integrating LLMs and AI services into .NET- and Python-based systems
• Designing and implementing AI-assisted workflows, copilots, or intelligent automation features
• Working with agentic AI patterns (e.g., task orchestration, tool-using agents, workflow automation)
• Applying prompt engineering, evaluation techniques, and guardrails to ensure reliability and compliance
• Collaborating with data and platform teams to operationalize AI—not just prototype it

Deep ML expertise is not required—we’re looking for strong engineers who understand how to apply AI capabilities in real products.

Qualifications:

• Bachelor’s or Master’s degree in Computer Science or equivalent practical experience
• 10+ years in software design and development using the Microsoft technology stack preferred
• Expert-level proficiency in
