Platform Engineer (Mid/Senior)

We’re looking for an experienced Platform Engineer to join our growing infrastructure team. If you enjoy working across cloud and bare-metal systems, value pragmatic automation, and thrive in a small, high-impact team - this is for you.

💼 Role Summary

As a Platform Engineer, you'll be responsible for building and maintaining our hybrid infrastructure - a mix of AWS-based cloud workloads and on-prem systems. You'll help us scale our platform with Kubernetes (EKS), automate environments, improve security and observability, and support product engineering with robust tooling and deployment workflows.

This is a hybrid role - part-remote, part-on-site (Warsaw area). You'll join a team of 2 engineers, working closely with developer teams and the CTO.

🔧 What You’ll Be Working On

• 🛠 Build and maintain infrastructure across AWS (EKS, EC2, RDS, Aurora, Redis, CloudFront) and Proxmox VE/Backup.

• 🧩 Support containerized workloads using Docker, orchestrated via Kubernetes (EKS) with Helm and Karpenter for scaling.

• 🧬 Manage IaC pipelines with Terraform and Ansible for consistent environment provisioning.

• 📦 Optimize app serving stack: nginx/passenger, HAProxy, Varnish, Cloudflare, and Let's Encrypt integrations.

• 🔍 Enhance platform observability using Prometheus, Grafana, AlertManager, and centralized logging via Elastic, Wazuh, and Netdata.

• 🔐 Support internal tooling: secrets with Vault, secure access via Boundary, and GitLab-based CI/CD.

• 🔨 Build and maintain internal developer platform (self-hosted Gitlab), CI runners, CI pipelines and deployment automation

• 🚦Enable zero-downtime deployments for monolithic Rails and Inertia.js applications.

✅ What We’re Looking For

Must-Have Skills

• 3+ years in Platform, DevOps, or Infrastructure Engineering.

• Strong Linux fundamentals (Debian/Alpine).

• Production-grade experience with AWS (EC2, EKS, RDS, IAM, Cloud networking (VPC)).

• Proficiency with Terraform, Ansible, and GitLab CI/CD.

• Experience operating Kubernetes, ideally EKS, with Helm and Karpenter.

• Solid understanding of containers and service orchestration.

• Familiarity with logging, monitoring, and alerting systems.

• Collaborative mindset, autonomy in hybrid/remote work, and strong problem-solving skills.

Nice-to-Have Skills

• Experience with Proxmox VE, custom hardware deployments, or hybrid cloud/on-prem setups.

• Knowledge of PostgreSQL RDS Proxy, Aurora, or ElastiCache Redis.

• Familiarity with Vault, Boundary, or other HashiCorp tooling.

• Experience optimizing high-traffic web stacks (Rails/Nodejs) or performance-tuning Nginx/Passenger/Varnish.

• Awareness of infrastructure security, SSL/TLS, and zero trust principles.

• Interest in future MLOps work (e.g., GPUs, ML infra) is a bonus.

🧠 How We Work

• We’re a small team, with high trust and shared ownership.

• You’ll work across the stack - from cloud architecture to deployment tooling.

• Our infra is built for scale, reliability and cost-efficiency, but we avoid unnecessary complexity.

• We value clarity, async communication, thoughtful automation and learning skills.

🌍 Work Model

• Location: Hybrid (remote + on-site in Warsaw)

• Schedule: Flexible, with some team-aligned core hours

• Language: English (tech), Polish (team communication)
