Freelance Algorithmic Trading Software Developer Jobs in Springfield, IL

We're building a world of health around every individual – shaping a more connected, convenient and compassionate health experience. At CVS Health®, you'll be surrounded by passionate colleagues who care deeply, innovate with purpose, hold ourselves accountable and prioritize safety and quality in everything we do. Join us and be part of something bigger – helping to simplify health care one person, one family and one community at a time.

We're looking for a Lead Director of Software Engineering who thinks like a founder, executes like a principal engineer, and leads like someone who's done it at the highest levels of the industry. You will set the bar – and then raise it.

• Drive technical strategy across a multi‑team engineering organization (50‑150+ engineers), setting architectural standards, defining engineering excellence benchmarks, and personally reviewing and elevating the work.
• Operational Efficiency. Every system design decision you make should start with the question: How to create 10x leverage? You will actively embed LLMs, generative AI, agentic workflows, and ML‑powered automation into the engineering lifecycle, not just as experiments, but as production‑grade differentiators.
• Own delivery at velocity. You ship. You are accountable for outcomes, not roadmaps. You hold your teams to the same standard.
• Partner at the executive level – with Product owners, Data Engineers, and Health care business leaders – translating business strategy into engineering bets with precision and conviction.
• Be the technical voice in the room – You call out architectural debt, push back on infeasible timelines, and advocate for the right engineering investment.

• 10+ years of progressive software engineering experience, including 5+ years leading large‑scale engineering organizations. You have built and scaled systems that serve tens of thousands of users. You know what happens when your system goes down.
• Deep, hands‑on technical foundation in distributed systems, cloud‑native architectures, and modern backend engineering at scale.
• Proven AI platform ownership. You have deployed production AI systems – not POCs, not demos, not limited to prompt engineering. You understand model deployment pipelines, vector databases, RAG architectures, LLM orchestration, inference optimization, and responsible AI principles.
• Track record of engineering transformation. You have migrated monoliths to microservices, modernized legacy platforms under real business pressure, and lived the consequences of every architectural decision you've made.

• Healthcare or highly regulated domain experience – You have navigated HIPAA, CMS compliance, PHI data handling development.
• Platform engineering ownership – You have built or led internal developer platforms, engineering productivity tooling.

Minimum

• Bachelor's degree in Computer Science, Software Engineering, Mathematics, or a closely related technical discipline – or equivalent demonstrated engineering depth through work history, open‑source portfolio, or verifiable technical contribution at scale.

Preferred

• Master's degree (M.S. or M.Eng.) in Computer Science, Artificial Intelligence, Machine Learning, Data Science, or a related quantitative field. Graduate‑level training in algorithms, distributed systems, statistical learning, or systems design gives us confidence in your technical ceiling.
