JOB DESCRIPTION

We are seeking a hands-on Systems Architect (SME) with deep expertise across infrastructure, platforms, and application ecosystems spanning cloud and on-premises environments. This role requires a proven practitioner who can analyze existing (“as-is”) systems and applications, document current state architectures, design future-state solutions, and implement system enhancements or technology transformations end-to-end. 

The ideal candidate is a technical leader and doer, not just an advisor – someone who can seamlessly collaborate across infrastructure, platform, application, DevSecOps, information systems security, and data teams while maintaining ownership of system reliability, performance, scalability, and security.  

QUALIFICATIONS

• Bachelor’s degree in Computer Science, IT or related technical discipline, or the equivalent combination of education, technical training, or work/military experience. 

REQUIRED KNOWLEDGE/SKILLS

Candidates must demonstrate hands-on experience in all the following areas: 

Infrastructure & Platforms 

• Enterprise networking (e.g., routing, switching, firewalls, load balancers, DNS) 

• Storage technologies (e.g., SAN, NAS, object storage) 

• Container platforms (e.g., Kubernetes, Docker) 

• Linux (Redhat, CentOS) operating systems (administration, hardening, automation) 

• IdAM – Public Key Infrastructure (PKI) hands-on for AuthN and AuthZ 

Cloud & On-Prem Technologies 

• Cloud platforms (AWS, Azure, and/or GCP) 

• Hybrid and on-prem infrastructure design and integration 

• Cloud networking, identity, security, and cost optimization 

Data & Application Platforms 

• Relational and NoSQL databases – relational (e.g., Oracle, PostgreSQL, MySQL, SQL Server) and NoSQL (e.g., MongoDB, Cassandra, DynamoDB, Redis) databases 

• Web services, APIs, and middleware 

• Software development lifecycle (SDLC) fundamentals 

• Event-based messaging systems (e.g., SQS, SNS, RabbitMQ) 

Engineering & Automation 

• Infrastructure as Code – Scripting & Automation: Python, Bash, PowerShell, Terraform, Ansible, or CloudFormation 

• Configuration management and scripting (e.g., PowerShell, Bash, Python, etc.) 

• CI/CD integration with infrastructure and platforms (e.g., Jenkins, Gitlab CI/CD, GitHub Actions, GitOps, ArgoCD) 

• Security best practices and system hardening 

• Monitoring & Incident Response: Proficiency with tools like Prometheus, Grafana, Splunk, ELK Stack, CloudWatch 

Architecture & Design 

• Ability to create: 

• As-is architecture documentation 

• To-be architecture and detailed engineering designs 

• Implementation and migration plans 

DESIRED KNOWLEDGE/SKILLS 

• Observability and monitoring tools (e.g., logging, metrics, tracing) 

• Zero Trust and modern security architectures 

• Data analytics, AI/ML platform exposure 

• Experience supporting production or mission-critical environments 

• Relevant certifications (e.g., cloud, systems, security, or architecture) 

• Knowledge of machine learning platforms (e.g., TensorFlow, PyTorch, SageMaker) 

• Familiarity with big data ecosystems (e.g., Hadoop, Databricks, Snowflake, Google, BigQuery) 

• Strong background in ITIL processes and agile methodologies 

• Certifications: AWS Solutions Architect / DevOps Engineer, Azure Administrator, Kubernetes CKA/CKAD, ITIL Foundation 

KEY RESPONSIBILITIES 

• Perform hands-on systems engineering across network, compute, storage, operating systems, middleware, databases, and applications 

• Analyze and document as-is infrastructure, platform, and application architectures 

• Work with the System Architect and Cloud Architect to create the detail engineering designs for modernization, optimization, and transformation initiatives 

• Lead and execute cloud and on-prem system implementations, migrations, and upgrades 

• Ensure systems meet availability, scalability, performance, security, and compliance requirements 

• Integrate infrastructure and platforms with DevOps and DevSecOps pipelines 

• Troubleshoot complex, cross-stack issues spanning infrastructure, platforms, and applications 

• Collaborate effectively with: 

• Infrastructure & Platform Engineers 

• Software Engineers 

• DevOps / DevSecOps Engineers 

• Data Engineers (ETL) 

• Data Modelers, Data Scientists, and Data Analysts 

• Produce clear technical documentation, diagrams, standards, and runbooks 

• Serve as a technical authority and escalation point for complex system issues 

• Communication Skills: 

• Ability to brief executives clearly and translate technical issues into business impact 

• Ability to work across organizations (internal and IC) to implement complex solutions 

Ideal Candidate Profile 

• Recognized SME with deep, hands-on technical expertise 

• Strong systems thinker with the ability to see and engineer across the full stack 

• Comfortable operating at both strategic architecture and tactical implementation levels 

• Excellent communication and collaboration skills across technical and non-technical teams 

• Proven ability to own complex systems from design through production
