Job Description

L3Harris seeks a Senior Cloud Software Architect who can bridge deep Cloud infrastructure expertise with modern software development practices for Cloud native software applications. The successful candidate has demonstrated experience developing applications for Multi-Cloud and Hybrid-Cloud environments, automating deployment of infrastructure and configuration, and architecting solutions leveraging Microservices and Event Driven patterns and will apply the experiences to support existing programs, support growth of business through new program pursuits and serve as a technology evangelist and thought leader. The candidate will shape the next generation of multi‑Cloud, Microservices‑based platforms, mentor the nation’s top engineers, and directly influence multimillion dollar contract wins.

Responsibilities:

• Design and oversee development of applications deployed to Cloud/Hybrid, providing up to six‑nine (99.9999%) availability. Requires understanding of Cloud services for compute (EC2, Lambda), storage (S3, EBS), and databases (RDS, Dynamo DB).
• Architect solutions with Microservices and Event Driven patterns. Requires experience selecting COTS tools and Cloud Services, scaling Event Driven solutions and understanding how to deliver highly available solutions across zones, regions and Cloud providers.
• Provide thought leadership when partnering with Business Development on successful contract pursuits and managing key partnerships with vendors. Requires ability to translate requirements and/or desired outcomes into solutions and document the design in technical volumes.
• Demonstrate benefits of L3Harris solutions through Proof of Concepts (PoC) in resolving customer pain points and partner with the customers to provide technical leadership. Requires ability to integrate COTS products with internally developed software to deliver the desired outcomes to customers.

The role is both a technical lead and a trusted advisor where you will mentor engineers, drive architectural designs and solutions, and act as the go‑to subject matter expert (SME) for Cloud, Infrastructure as Code (IaC), Configuration-as-Code (CaC), DevSecOps, and Microservices/Event-Driven architecture across multiple programs.

Essential Functions:

• Architect End‑to‑End Cloud solutions – Define reference architectures, deployment topologies, and data‑flow patterns for mission critical workloads delivering up to six‑nine (99.9999%) availability. Create and maintain multi‑Cloud reference architectures, including network topology, data management, observability, and disaster recovery designs.
• Design Microservices-based solutions – use containers (Docker, OCI) orchestration (Kubernetes, Red Hat OpenShift, Amazon EKS, Azure AKS, GKE), service mesh (Istio/Linkerd), and distributed messaging (Kafka, Pulsar, Pub/Sub) to meet scalability & resiliency goals. Define service boundaries, API contracts (REST/GraphQL, gRPC), Event Driven patterns, and schema registry strategies for data intensive applications.
• Partner with customers - Translate mission level requirements into technical specifications, implement Proof of Concepts (PoC), support system‑integration testing, and oversee deployment of solutions to both customer and L3Harris managed Cloud Landing Zones.
• Partner with Business Development - Author white papers, produce technical content for business capture initiatives, perform trade studies, and influence product roadmaps through emerging technology (e.g., serverless, edge compute, AI enhanced networking). Build & maintain strategic relationships with Cloud vendors and key partners to influence product direction and negotiate commercial and technical outcomes (pricing, service commitments, new platform capabilities) in a timely manner in support of critical initiatives.
• Mentor & Evangelize - mentor & enable development teams, run architecture review sessions, provide hands-on workshops, champion best practice coding standards, and help develop Cloud expertise within the organization. Stay abreast of emerging Cloud services (e.g., serverless, AI/ML, edge computing) and evaluate fit for L3Harris mission needs.
• Ability to obtain and maintain a US Security Clearance.

Qualifications:

• Bachelor’s Degree and a minimum of 12 years of prior relevant experience. Graduate Degree and a minimum of 10 years of prior related experience. In lieu of a degree, minimum of 16 years of prior related experience.

Preferred Additional Skills:

• 8+ years of professional experience designing, building, and operating Cloud solutions; 4+ years in a senior architect or Lead Engineer role
• 5+ years of design & implementation of distributed systems using event driven architectures (Kafka, Pulsar, Pub/Sub, RabbitMQ) and API management (API gateway, Istio, Kong) and experience successful deployment of solutions to production and supporting operational systems.
• 5+ years of demonstrated production experience on a major Cloud Service Providers (AWS, Azure, GCP).
• 5+ years of hands‑on experience with Docker, Kubernetes (OpenShift/EKS/AKS/GKE), Helm, and service mesh technologies.
• 8+ years of proficiency in modern programming languages (Java, JavaScript/NodeJS, Python, Go, C#) and deep understanding of CI/CD, automated testing, and version control workflows (Git, Gitlab).
• Hands-on experience delivering solutions leveraging FedRamp High Authorized services (GovCloud, Assured Workloads) and understanding of the differences with Public Cloud services
• Hands‑on experience with Terraform, AWS CDK, Azure Bicep, or Pulumi; familiarity with GitOps concepts.
