About the role
CI/CDObservabilityIncident ResponseUX Design
The tasks that service provider will be expected to perform include any or all of the following.
· Develop, configure, and monitor DevSecOps pipelines using pipelines-as-code with integrated quality gates (linting, testing, security scanning, environment promotion), ensuring efficient and reliable CI/CD processes.
· Automate deployments with progressive delivery strategies (e.g., canary, blue/green) and feature flagging, incorporating automated rollback mechanisms to ensure reliable and repeatable releases.
· Manage deployment and setup of services and applications, ensuring they are configured correctly and optimized for the production environment.
· Manage infrastructure provisioning, scaling, and availability using Infrastructure-as-Code (IaC) practices, with drift detection, policy-as-code enforcement, and tested disaster recovery runbooks (RTO/RPO).
· Implement monitoring and observability solutions (metrics, logs, traces) aligned with service level objectives (SLOs), ensuring application and infrastructure performance and health are tracked effectively.
· Coordinate incident management through on-call rotations, incident playbooks/runbooks, and blameless post-incident reviews, ensuring production issues are resolved swiftly with lessons learned embedded.
· Perform performance tuning of both applications and infrastructure to ensure optimal usage of resources and user experience.
· Integrate security practices into CI/CD pipelines, including software supply-chain security (SBOMs, provenance checks), secrets management, and least-privilege access, to maintain secure system configurations.
· Design and maintain internal developer platforms with golden paths, reusable templates, and policy-based guardrails, enabling teams to securely and consistently self-serve infrastructure and application environments.
· Plan and implement upgrades and migrations of software stack.
· Monitor, analyze, and optimize cloud costs by applying FinOps practices such as budgeting, forecasting, rightsizing, and implementing show back/chargeback models to maximize cost efficiency.
· Document pipelines, processes, and infrastructure for reusability and knowledge transfer.
· Establish artifact repositories and image signing; enforce software supply-chain policies and integrity checks.
· Design and implement cloud solutions that meet business objectives, with defined operational Key Performance Indicators (KPIs) for availability, reliability, and performance, and clear ownership boundaries.
· Manage and optimize cloud infrastructure and operations against defined Key Performance Indicators (KPIs) for cost, performance, and availability, adhering to operational excellence best practices.
· Conduct cost analysis and monitor cloud expenses using Financial Operations (FinOps) practices, including budgeting, forecasting, rightsizing, and implementing showback/chargeback models.
· Ensure security, compliance, and data protection through the implementation of the shared responsibility model, zero-trust principles, encryption, and adherence to relevant compliance frameworks (e.g., General Data Protection Regulation (GDPR)).
· Automate cloud processes and workflows using scripting and tools.
· Troubleshoot and resolve cloud-related issues to maintain service levels and meet defined operational Key Performance Indicators (KPIs) for availability and reliability.
· Collaborate with development teams to support cloud-based applications.
· Evaluate and recommend new cloud services and technologies to enhance capabilities, improve efficiency, and reduce costs while aligning with architectural standards.
· Create and maintain comprehensive documentation for cloud systems, architectures, and operational processes to ensure knowledge sharing and operational continuity.
· Manage the end-to-end cloud architecture, development, and migration lifecycle, including strategy definition, landing zone design, networking, data migration planning, and execution via detailed runbooks.
· Provide cloud expertise and support to stakeholders and teams.
· Establish cloud landing zones with governance guardrails (e.g., policies, tagging, Role-Based Access Control (RBAC)) and a well-defined environment hierarchy to ensure security and compliance.
· Implement comprehensive observability (monitoring, logging, tracing), incident response processes, and disaster recovery/business continuity plans (DR/BCP) with defined Recovery Time and Point Objectives (RTO/RPO).
