Primary Responsibilities :

- Strategic Application Architecture Design
- Champion observability‑driven architecture (golden signals, SLOs, and error budgets) to ensure systems are designed for measurable reliability and rapid, data‑driven iteration
- Compliance, Security & Governance
- Implement policy‑as‑code and guardrails‑by‑default (e.g., service policies, RBAC, OPA) to operationalize governance across environments
- Platform Reliability & Optimization
- Establish end‑to‑end observability (OpenTelemetry‑aligned tracing, metrics, logs, and profiling) with actionable dashboards, SLO reporting, and automated alerting to accelerate MTTR and improve customer experience
- Embed resilience patterns (circuit breakers, retries, timeouts, bulkheads, partitioning, autoscaling) and validate them continuously via chaos experiments and game days
- Technology Thought Leadership
- Stay ahead of trends in microservices, event‑driven architecture, serverless computing, container orchestration, observability practices, chaos engineering, and AI‑enhanced developer platforms (DevEx) to continuously evolve platform capabilities
- Cross‑Functional Collaboration
- Resilience, Disaster Recovery & Fault Tolerance
- Define RTO/RPO objectives,



implement multi‑zone/region failover patterns, and regularly test disaster recovery through automated drills
- Automation, Scalability & CI/CD Enablement
- Leverage automation tools and IaC practices to streamline deployments, improve operational efficiency, and support frictionless scaling of microservices and event-based workflows
- Vendor & Platform Partner Engagement
- Mentorship & Engineering Enablement
- Provide guidance and mentorship to developers and architects, fostering a culture of up-to-date engineering excellence
- Comply with the terms and conditions of the employment contract, company policies and procedures, and any and all directives (such as, but not limited to, transfer and/or re-assignment to different work locations, change in teams and/or work shifts, policies in regards to flexibility of work benefits and/or work environment, alternative work arrangements, and other decisions that may arise due to the changing business environment). The Company may adopt, vary or rescind these policies and directives in its absolute discretion and without any limitation (implied or otherwise) on its ability to do so

Required Qualifications :

- Proficiency with Infrastructure as Code tools (Terraform) and GitOps workflows

- Solid experience with microservices, containers, and orchestration technologies (Docker, Kubernetes)

- Hands‑on experience establishing end‑to‑end observability (metrics/traces/logs), defining SLOs & error budgets, and building actionable dashboards/alerts

- Practical experience with chaos engineering and resilience validation (e.g., failure injection, fault isolation, game days) and codifying DR tests.

- Experience implementing automation and AIOps for incident reduction, anomaly detection, and auto‑remediation; familiarity with integrating AI‑assisted DevEx into SDLC workflows

- Preferred Qualifications:

- Architecture certifications from major cloud providers (GCP, AWS, Azure)

- Understanding of industry‑specific compliance and interoperability standards (HL7, FHIR, HIPAA) when relevant

- Proven ability to design and integrate event‑driven and streaming pipelines using cloud‑native messaging, data, and event processing services

- Proven solid analytical, problem‑solving, decision‑making, and communication abilities

- 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
