Job description

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/Sev‑2). 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

• 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

• 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.
