Original job description

Optum is a global organization that delivers care, aided by technology to help millions of people live healthier lives. The work you do with our team will directly improve health outcomes by connecting people with the care, pharmacy benefits, and data they need to feel their best. Here, you will find a culture guided by diversity and inclusion, talented peers, comprehensive benefits, and career development opportunities. Come make an impact on the communities we serve as you help us advance health equity on a global scale. Join us to start Caring. Connecting. Growing together.

As a Senior Information Security Engineer on our Security Operations Engineering team, you will play a critical role in designing, deploying, and maintaining enterprise web application security and traffic management solutions across F5 BIG-IP and Cloudflare platforms. You will collaborate across application development, network, and cloud infrastructure teams to protect web applications against emerging cyber threats, optimize WAF and edge security controls, and streamline security operations using modern automation and enterprise-approved AI tools.

You will enjoy the flexibility to telecommute* from anywhere within the U.S. as you take on some tough challenges.

Primary Responsibilities:

Design, deploy, configure, and maintain F5 BIG-IP architectures (LTM, ASM/WAF, APM, DNS/GTM) and Cloudflare edge security solutions
Manage and optimize Web Application Firewall (WAF) policies, Cloudflare security rules, and DDoS protection mechanisms to safeguard web applications
Monitor network traffic, investigate security incidents, and execute technical mitigation for web application threats and access issues
Leverage enterprise-approved AI tools to streamline workflows, automate repetitive tasks, analyze incident data, and drive continuous operational improvement
Evaluate emerging security trends, threats, and traffic management technologies to inform solution design and strategic technical innovation
Collaborate with application development, network, and cloud infrastructure teams to integrate traffic management and security policies into architecture pipelines
Maintain comprehensive technical documentation, operational runbooks, and disaster recovery procedures for F5 and Cloudflare deployments
Provide technical guidance, troubleshooting support, and operational mentorship to junior security engineers and cross-functional partners

You’ll be rewarded and recognized for your performance in an environment that will challenge you and give you clear directions on what it takes to succeed in your role as well as provide development for other roles you may be interested in.

Required Qualifications:

5+ years of experience in information security engineering, network security, or application traffic management
3+ years of hands-on experience designing, configuring, and managing F5 BIG-IP modules (e.g., LTM, ASM/WAF, APM, or DNS/GTM)
2+ years of experience analyzing application layer protocols (HTTP/HTTPS, SSL/TLS, DNS) and web application security vulnerabilities

Preferred Qualifications:

Bachelor’s degree in Computer Science, Information Technology, Cybersecurity, or a related technical field
2+ years of hands-on experience administering Cloudflare security services (e.g., WAF, DNS, DDoS protection, Rate Limiting, or Workers)
2+ years of experience using scripting or automation tools (e.g., Python, PowerShell, iRules, or API integrations) for task orchestration
F5 Certified Administrator / Technology Specialist, Cloudflare certification, or CompTIA Security+/Network+ certifications
Experience integrating WAF policies and edge security into CI/CD deployment pipelines or infrastructure-as-code workflows
Experience operating within healthcare or highly regulated enterprise IT environments

*All Telecommuters will be required to adhere to UnitedHealth Group’s Telecommuter Policy.

Pay is based on several factors including but not limited to local labor markets, education, work experience, certifications, etc. In addition to your salary, we offer benefits such as, a comprehensive benefits package, incentive and recognition programs, equity stock purchase and 401k contribution (all benefits are subject to eligibility requirements). No matter where or when you begin a career with us, you’ll find a far-reaching choice of benefits and incentives. The salary for this role will range from $91,700 - $163,700 annually based on full-time employment. We comply with all minimum wage laws as applicable.

Pursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records.

Application Deadline: This will be posted for a minimum of 2 business days or until a sufficient candidate pool has been collected. Job posting may come down early due to volume of applicants.

At UnitedHealth Group, our mission is to help people live healthier lives and make the health system work better for everyone. We believe everyone–of every race, gender, sexuality, age, location, and income–deserves the opportunity to live their healthiest life. Today, however, there are still far too many barriers to good health which are disproportionately experienced by people of color, historically marginalized groups, and those with lower incomes. We are committed to mitigating our impact on the environment and enabling and delivering equitable care that addresses health disparities and improves health outcomes - an enterprise priority reflected in our mission.

UnitedHealth Group is an Equal Employment Opportunity employer under applicable law and qualified applicants will receive consideration for employment without regard to race, national origin, religion, age, color, sex, sexual orientation, gender identity, disability, or protected veteran status, or any other characteristic protected by local, state, or federal laws, rules, or regulations.
