Job Overview

We’re seeking a Senior DevOps / Cloud Engineer to play a pivotal role in stabilizing, modernizing, and preparing our systems for this transition. You’ll be stepping into a challenging environment, with limited documentation, legacy monolithic systems, and a team undergoing significant change. But this is also your opportunity to drive real impact—bringing stability to a vital system, preparing it for the future, and helping shape the technical direction.

You’ll collaborate closely with leadership and remaining technical experts to ensure knowledge transfer, make the system cloud-ready, and support a critical data center exit by the end of the year.

Your immediate impact in the first 3-6 months will be:

• Understand the current system landscape (through documentation, shadowing, and hands-on exploration) and become familiar with our digital measurement solutions.
• Stabilize and modernize the on-prem infrastructure, making it cloud-ready (containerized and deployable in any modern cloud environment).
• Collaborate with colleagues to build out CI/CD pipelines and automate key processes.
• Contribute to selecting the appropriate cloud provider and participate in defining the future-state architecture.
• Lead and support the migration of systems from on-premises to the cloud environment.
• Ensure proper knowledge transfer and documentation during the transition

Responsibilities

• Dive deep into our legacy systems (built with multiple languages like Python 2/3, PHP, JavaScript, Go, C#) and modernize them for containerized environments (Kubernetes, Docker).
• Collaborate with team members and stakeholders to gather insights and ensure knowledge continuity.
• Architect, implement, and optimize CI/CD pipelines (Jenkins-based).
  Prepare the system for migration: optimize infrastructure, document processes, and propose best-fit solutions for cloud deployment.
• Actively contribute to the selection of the cloud provider and design decisions
• Work independently and take ownership of driving initiatives forward in a fast-paced, resource-constrained environment.

Requirements

• Proven experience with cloud environments (AWS preferred), containerization (Docker, Kubernetes), and infrastructure as code (e.g. Terraform).
• Solid experience in DevOps, system administration, and infrastructure optimization.
• Strong Python (2 and 3) skills, along with some experience in other languages (PHP, JavaScript, Go) and a willingness to navigate legacy codebases.
• Knowledge of CI/CD pipelines, especially Jenkins, and experience building them from scratch.
• Familiarity with SQL databases (MariaDB, MySQL, PostgreSQL), NoSQL (MongoDB, Redis), and streaming technologies (Kafka).
• Strong knowledge of Linux environments.
• A fearless mindset: ready to question, break, fix, and improve existing systems.
• Excellent communication and collaboration skills for working across teams and transferring knowledge effectively.
• Interest in publishing market measurement or large-scale data systems is a plus.
