Senior Platform Engineer, Poland

DoiT is a global technology company that works with cloud-driven organizations to leverage the cloud to drive business growth and innovation. As a Senior Platform Engineer, you will develop and evolve foundational software and services that empower product and development teams, ensuring scalability, reliability, and security of the platform.

Responsibilities:

• Function as an individual contributor within the team: actively collaborating with peers through thorough code reviews, providing constructive support and mentorship, and contributing to a unified technical direction for the platform. This role also requires collaboration with individuals in feature teams, providing them with support and working with them to facilitate the adoption of developed platform features
• Architect, Design, and Implement Infrastructure as Code (IaC): You will treat our infrastructure as a sophisticated software system, responsible for its comprehensive lifecycle management using Terraform. This involves applying best practices from software engineering, such as designing reusable code modules, implementing robust unit and integration testing strategies, and ensuring that our infrastructure is consistently provisioned and managed in a predictable and repeatable manner
• Deploy, Manage, and Optimize Kubernetes Clusters on GCP (GKE) and AWS (EKS): You will take ownership of the deployment, configuration, and ongoing maintenance of our Kubernetes clusters on GCP Google Kubernetes Engine (GKE) and AWS Elastic Kubernetes Service (EKS) kit. This includes managing node groups, configuring network policies, implementing service meshes, handling cluster upgrades, and ensuring high availability and fault tolerance. You will also be responsible for monitoring cluster health, performance, and resource utilization, and proactively addressing any issues that arise
• Develop and Refine Internal Software Delivery Systems (CI/CD: You will design, implement, and maintain robust Continuous Integration/Continuous Deployment (CI/CD) software specifically tailored for our platform components. This involves integrating tools like Argo CD or Atlantis, applying advanced programming concepts to automate build and release processes, and ensuring seamless deployment of platform updates. You will also focus on optimizing pipeline performance and reducing deployment times
• Diagnose, Troubleshoot, and Resolve Platform-Related Issues: You will be the primary point of contact for diagnosing and resolving platform-related issues, including performance bottlenecks, scalability challenges, and security vulnerabilities. This involves utilizing advanced troubleshooting techniques, analyzing logs and metrics, and collaborating with development teams to identify and resolve root causes. You will also contribute to creating comprehensive incident response plans and post-mortem analyses
• Drive Automation Initiatives to Streamline Operational Tasks and Enhance System Reliability: You will champion automation initiatives to eliminate manual operational tasks, reduce human error, and improve overall system reliability. This involves developing scripts, tools, and workflows to automate tasks such as infrastructure provisioning, configuration management, and monitoring. You will also proactively identify opportunities for automation and drive continuous improvement in our operational processes
• Act as a Strategic Partner to Development Teams, Understanding and Addressing Their Infrastructure Needs: You will foster strong relationships with feature teams, treating them as your internal customers. You will actively engage with them to understand their infrastructure and developer experience requirements, provide expert guidance on platform capabilities, and ensure our platform effectively supports their development workflows. You will also translate developer needs into actionable platform product features and roadmaps
• Drive Development of Internal Platform Product and Services: You will actively participate in the full software development lifecycle (design, code, test, and deploy) of internal tools and APIs. These services will enhance the functionality, self-service capability, and usability of our platform, directly improving developer productivity across the organization
• Implement and Enforce Rigorous Security Best Practices and Ensure Compliance with Industry Standards: You will be responsible for implementing and enforcing robust security best practices across our platform, including access control, vulnerability management, and data encryption. You will also ensure compliance with relevant industry standards and regulations, such as SOC 2 and GDPR. You will also conduct regular security audits and penetration testing to identify and mitigate potential security risks
