Original job description

McKesson is an impact-driven, Fortune 10 company that touches virtually every aspect of healthcare. We are known for delivering insights, products, and services that make quality care more accessible and affordable. Here, we focus on the health, happiness, and well-being of you and those we serve – we care.

What you do at McKesson matters. We foster a culture where you can grow, make an impact, and are empowered to bring new ideas. Together, we thrive as we shape the future of health for patients, our communities, and our people. If you want to be part of tomorrow’s health today, we want to hear from you.

About the Role

McKesson is seeking a Sr. Software Developer to design, build, and scale modern software solutions that support healthcare technology innovation. In this role, you will help deliver secure, reliable, and scalable applications across cloud-native platforms while contributing to AI-enabled engineering practices, multi-agent systems, LLM applications, and automation across the software development lifecycle.

You will work across engineering, architecture, product, security, and platform teams to develop API-first services, improve system reliability, and modernize application delivery using Azure, Kubernetes, event-driven patterns, DevSecOps, and AI-augmented development practices.

What You’ll Do

Design, develop, and maintain scalable full-stack applications using Java, Python, React, REST APIs, API-first architecture, MongoDB, and PostgreSQL.

Build and enhance AI-enabled applications using LLMs, RAG patterns, agentic workflows, and multi-agent system design.

Architect and deliver cloud-native solutions using Microsoft Azure, Kubernetes, containers, microservices, and event-driven systems.

Lead technical design discussions and help define software architecture, engineering standards, and reusable development patterns.

Improve CI/CD pipelines, DevSecOps practices, test automation, monitoring, and platform automation.

Troubleshoot complex production and non-production issues; analyze root causes and recommend long-term solutions.

Partner with cross-functional teams to deliver secure, compliant, reliable, and maintainable software in a regulated enterprise environment.

Mentor engineers through code reviews, technical guidance, and shared best practices.

Basic Requirements

7+ years of professional software engineering experience, including enterprise-scale application development.

Experience building applications with Java, Python, React, JavaScript/TypeScript, REST APIs, or related full-stack technologies.

Experience designing, developing, and optimizing database solutions using MongoDB, PostgreSQL, relational data models, document databases, query optimization, indexing, and data integration patterns.

Hands-on experience with cloud-native architecture, preferably Azure, Kubernetes, containers, microservices, or serverless patterns.

Hands-on experience with AI-assisted software development or agentic coding tools and practices, including Claude Code, GitHub Copilot, code analysis, automated test generation, documentation support, and developer productivity workflows.

Experience designing or integrating APIs, distributed systems, event-driven services, or enterprise integrations.

Experience with CI/CD pipelines, DevOps or DevSecOps practices, Git-based workflows, automated testing, and release processes.

Experience applying secure coding, software quality, scalability, reliability, and maintainability practices.

Experience working in Agile delivery environments with product, architecture, security, and operations partners.

Bachelor’s degree in Computer Science, Engineering, Information Technology, or related field, or equivalent experience.

Preferred Skills/Experience

Experience building AI applications using LLMs, RAG, vector databases, prompt engineering, orchestration frameworks, or agentic AI patterns.

Experience with multi-agent systems, autonomous workflows, AI copilots, or AI-assisted automation.

Experience with Azure services, Kubernetes operations, event streaming, messaging platforms, or API gateways.

Experience with MongoDB, PostgreSQL, database performance tuning, schema design, indexing strategies, data migration, and secure data access patterns.

Experience contributing to open-source frameworks, internal developer platforms, reusable libraries, or engineering accelerators.

Experience with observability tools, infrastructure as code, policy-as-code, SRE practices, or platform engineering.

Experience applying AI-assisted software development and agentic coding capabilities across the SDLC, including code generation, code review, repository analysis, test automation, documentation, risk detection, and developer productivity improvement.

Experience working in healthcare, regulated technology, security-conscious, or compliance-driven environments.

Travel / Work Environment / Physical Requirements

Work model may be remote, hybrid, or office-based depending on business and team needs.

Occasional travel may be required for team collaboration, planning, or business meetings.

Ability to work at a computer for extended periods in a standard office or remote-work environment.
