Senior System Engineer

The Senior System Engineer serves as the senior technical authority within the Service Delivery organization. This hands-on leadership role is responsible for end-to-end system architecture, technical design, and execution across complex, large-scale deployments. You will define technical strategy, ensure delivery excellence, mentor engineers, and act as the top-level escalation point for critical incidents. Working closely with the PMO and cross-functional teams, you will safeguard delivery integrity, enforce technical standards, and ensure all projects meet performance, security, and compliance requirements.

Key Responsibilities

• Lead solution architecture and design for multi-site, geo-redundant systems. Develop High-Level and Low-Level Designs (HLD/LLD) and validate Detailed-Level Designs (DLD) before deployment.

• Define reference architectures and golden images; champion automation-first strategies for provisioning, configuration, patching, and system upgrades.

• Own technical delivery plans, risk identification, and mitigation strategies across staging and production environments. Ensure proper validation through documented

unit, integration, and UAT testing.

• Partner with engineering and PMO teams to maintain governance frameworks, manage change control, and align key stakeholders at every project milestone.

• Serve as the highest-level (Tier-3/4) escalation point for critical incidents (Sev-1/Sev2). Lead incident resolution, conduct root-cause investigations, and drive

implementation of permanent corrective measures.

• Act as the technical lead during pre-sales and delivery phases clarifying requirements, validating assumptions, and translating business needs into technical designs in

collaboration with Sales, Service Excellence, Product, and PMO teams.

• Lead technical workshops, architecture reviews, and formal handovers. Represent engineering leadership in change advisory boards and go/no-go decision meetings.

• Ensure HLDs, LLDs, runbooks, disaster recovery procedures, and security hardening guides are up to date, version-controlled, and consistently applied across delivery

teams.

• Mentor System Engineers and Senior Engineers, review technical designs and scripts, set quality benchmarks, and guide professional growth and cross-training efforts.

• Drive close collaboration with Sales, Service Excellence, Product, and Customer teams to deliver cohesive and high-quality solutions.

Technical Skills and Experience

• Linux Administration: Advanced expertise in RHEL, CentOS, and Ubuntu, including system hardening, high-availability clustering, and performance optimization.

• Networking and Security: Strong understanding of switching, routing, firewalls, VLANs, and core protocols (TCP/IP, DNS, NTP, LDAP, SMTP); capable of making

architecture-level security and design decisions.

• Virtualization and Cloud: Skilled in KVM, VMware, and Hyper-V platforms; proficient in designing hybrid architectures across AWS, Azure, and GCP with cost and

performance optimization.

• Data and Observability: Hands-on experience with MySQL, MariaDB, and PostgreSQL; familiarity with centralized logging, metrics, and alerting tools such as syslog-ng and

Elastic Stack.

• Automation and Scripting: Proficient in Bash and Linux shell scripting; working knowledge of Python, Ansible, and Terraform for infrastructure automation and

CI/CD implementation.

• Containerization: Experience with Docker, Docker Swarm, and Kubernetes for building, deploying, and managing scalable containerized applications.

• Implementation Support: Willing to engage directly in hands-on configurations and deployments for critical or high-priority projects.

Requirements

• Minimum 10 years of experience in systems engineering, including at least 3 years in an architecture or principal engineering capacity managing complex deployments.

• Preferred certifications include RHCE, AWS/Azure Solutions Architect, Kubernetes (CKA/CKAD), and network/security credentials such as CCNP.

• Willingness to travel for onsite deployments, implementations, and cutover activities when necessary.

• Strong leadership, communication, and stakeholder management skills, with the ability to influence and drive outcomes across technical and business teams.
