System Admin (Cameo/Polarian), Chennai, TN, IN
Infra-System Admin
Primary Skills: CAMEO/ Polarion
Secondary Skills: Enovia
Linux, Devops, Jenkin etc.,
Primary Objective
Own the setup, support, maintenance and administration of the Cameo (CATIA Magic) MBSE stackincluding Teamwork Cloud and Cameo Collaborator (via Web Application Platform). Ensure a secure, efficient and reliable modeling environment across non production and production.
Environment / Tech Context
- Modeling tools: Cameo Systems Modeler based on MagicDraw, SysML/UML plug ins and reporting framework.
- Repository & collaboration: Teamwork Cloud for central model storage, element level versioning, RBAC, web admin, REST/OSLC endpoints, supports branching/merging and large models.
- Web access & reviews: Cameo Collaborator on Web Application Platform, typically hosted on Tomcat and recommended on separate nodes from TWC.
- Identity & access: SSO integration available via TWC Admin, role based permissions and global/custom scopes.
- Licensing: DSLS license server, clients check out licenses, admin monitors usage and compatibility with tool versions.
- Data tier & HA: Cassandra back end for TWC, supports clustered deployments and hot/cold backups, DR procedures include nodetool snapshot/restore.
- Platform requirements: Current CATIA Magic releases align on modeling tools and recommend specific server profiles for TWC/Collaborator.
Key Responsibilities (supporting The Infrastructure Lead)
Monitoring & Health
- Monitor application and system logs (TWC services, Tomcat, Cassandra) and respond to alerts. Validate repository and web admin availability.
- Track model throughput and REST/OSLC service health, tune JVM/connector/thread pools as needed.
Access, Roles & Security
- Operate SSO (configure directories, bind/timeout policies) and maintain RBAC in TWC Admin.
- Manage TLS certificates/keystores across TWC, apply vendor hardening guidance and secure container defaults.
- Patch OS/Java/Cameo tools/TWC in approved timeframes, validating against vendor compatibility.
Backups, DR & Capacity
- Run Cassandra cold/hot backups (nodetool snapshot, drain) with DBA teams and document RPO/RTO, periodically perform restores on Non-Prod env.
- Plan cluster sizing/replication factor and scale out with storage separation for data/commit logs.
- Track storage growth for repositories, Collaborator exports and forecast capacity.
Build, Release & Environment Management
- Install/upgrade Teamwork Cloud and Web Application Platform/Cameo Collaborator.
- Validate DSLS license server connectivity.
- Manage non prod refreshes from PROD, including access controls and environment alignment, coordinate with CAMEO Functional SME teams on best practices.
Troubleshooting & Performance
- Triage SSO auth, model commit conflicts, REST/OSLC errors and Collaborator rendering; conduct RCA and preventive actions.
- Tune JVM (heap/GC), web container in line with vendor guidance.
Reporting, Audits & Licensing
- Generate usage/health reports and keep audit evidence (access, changes, DR tests).
- Operate DSLS for floating licenses, monitoring and ensure tool compatibility.
Documentation & Knowledge Transfer
- Maintain architecture diagrams, config baselines, SOPs and runbooks. Train L1/engineering teams on common procedures.
Required Experience & Skills
- 68 years administering collaborative engineering platforms, specifically with Cameo + Teamwork Cloud in on prem Linux platform VMs.
- Strong skills in Linux, Java/Tomcat, Cassandra (snapshot/restore) process, TLS/certificates and SSO.
- Proven experience with TWC Admin (roles/permissions, project operations) and Collaborator deployment.
- Familiar with REST/OSLC endpoints and model collaboration workflows.
- Comfortable with DSLS licensing operations and client connectivity.
- Experience with TWC clustering and production HA patterns, Zookeeper.
- Observability stacks (Grafana) and automation (Bash/PowerShell).
- Familiarity with Cameo Systems Modeler plug ins (Simulation Toolkit, Requirements Modeler) and reporting.
Soft Skills
- Clear written and verbal communication with engineering and non technical stakeholders, disciplined change management and incident handling.
