Headquartered in London with global offices, Cognism’s contact data and contextual signals are trusted by thousands of revenue teams to eliminate the guesswork from prospecting.

OUR WORK MODEL

Hybrid: This is a hybrid role, requiring you to work from our Warsaw office 2 days per week, with flexibility to work remotely on other days.

YOUR ROLE As a Platform Engineer at Cognism, you will design, build, and maintain the infrastructure that powers our high-scale development and deployment environment. Working as part of a small but mighty Platform team, your expertise will be instrumental in driving performance, scalability, and developer efficiency across the business.

YOUR CHALLENGES & OPPORTUNITIES

  • Streamline Deployments – Build and manage infrastructure-as-code to enable fast, standardized, and reliable deployments across teams.
  • Advance CI/CD Pipelines – Evolve and maintain CI/CD systems that minimize downtime and maximize deployment speed and consistency.
  • Boost Developer Experience – Create tooling and automation to reduce friction in development workflows and accelerate delivery.
  • Foster Collaboration – Work cross-functionally with Security, Data, ML, and Product teams to ensure infrastructure aligns with both technical and business goals.
  • Lead Incident Readiness – Own systems post-deployment, driving observability, failover planning, and incident response.
  • Drive Continuous Improvement – Participate in architecture discussions, retrospectives, and planning to improve infrastructure processes and resilience.
  • Champion Documentation – Create and maintain documentation and post-incident reviews to support shared learning and onboarding.

OUR EXPECTATIONS

  • Cloud Expertise – 3+ years experience managing production systems on AWS (experience with Azure and AliCloud a bonus).
  • Container Orchestration – 2+ years using Kubernetes in production environments.
  • Infrastructure as Code – 3+ years experience with Terraform and GitOps workflows.
  • Observability First – Proficient with Prometheus, Grafana, OpenTelemetry, Coralogix, Loki, or similar tools.
  • System-Level Thinking – Analytical mindset with the ability to consider the whole system, not just the task at hand.
  • Automation & Scripting – Solid command of Linux and scripting languages (Python, Bash, etc.).
  • CI/CD Familiarity – Experience with Github Actions, ArgoCD, or similar tools.
  • Strong Communicator – Excellent collaboration skills with an ability to explain technical concepts clearly.
  • Certifications Welcome – AWS, Kubernetes, or Terraform certifications are a plus, but not required.
  • Proficiency in coding with Python or Golang

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
