🏢 Summary: Platform Engineer role responsible for owning and scaling a self-hosted production stack running on Docker Compose.

But our journey does not end here - we want to continue our growth. If you’re goal-driven and looking for new opportunities, join our team! What awaits you is an enriching and collaborative environment that fosters your growth at every step. 📈 The role: We are looking for an experienced Platform Engineer (full-time or part-time). Own the production system end-to-end. Today the entire stack runs self-hosted on Docker Compose: a custom-built lighttpd with database-driven virtual hosts, MariaDB, a Kubo IPFS node, Dozzle for logs, and Uptime Kuma for monitoring. There is no CI/CD pipeline, no infrastructure-as-code, no application performance monitoring, and the scaling story is vertical for now. Your job is to keep the lights on, automate the manual work, design how this system scales, and make pragmatic build-vs-buy decisions on cloud services (load balancing, object storage, managed databases) as we grow. 📈 Your Responsibilities : Operate the production system: deploys, rollbacks, capacity, incident response. Design and execute the scaling roadmap — horizontal scaling, load balancing, caching layers, object-storage offload, database replication, IPFS-node fan-out. Evaluate and integrate cloud building blocks (managed databases, object storage, CDN, load balancers) where they earn their cost. Stand up CI/CD pipelines (greenfield — likely GitHub Actions) covering test, build, image push, and deploy across all services. Establish observability: metrics, logs, error tracking, SLOs, and meaningful alerts. Manage TLS / ACME automation, DNS, and secrets handling — replace today's hardcoded credentials with a proper secret-management story. Introduce infrastructure-as-code (Terraform or comparable) so the production system is reproducible. Use AI coding assistants to author IaC modules, runbooks, and incident-response playbooks. 🔑 Tech Stack You'll Work With or Introduce: Docker, Docker Compose, image building. Linux (Debian-style), Bash, Python for scripting. Lighttpd today (niche, with DB-driven vhost logic you'll learn) - likely to be reconsidered as we scale. MariaDB - including replication, backup/restore drills, performance tuning. Kubo IPFS node, private-swarm operation, gateway scaling. Let's Encrypt / ACME / Certbot. Load-balancing layer (to be chosen - HAProxy, Caddy, NGINX, ALB/NLB, etc.). Object storage (to be chosen - S3, GCS, R2, MinIO; mainly for non-IPFS payloads and backups). CI/CD (likely GitHub Actions, to be confirmed). Observability stack (likely Prometheus + Grafana + Loki + Sentry - to be introduced). IaC: Terraform or Ansible (to be introduced). One of AWS / GCP / Azure as the long-term cloud target - tbd Hard Skills - Must-Have: 5+ years professional Linux sysadmin / DevOps / SRE / Platform Engineering. Docker fluency: writing, debugging, and optimizing Dockerfiles and multi-service compose stacks. Networking fundamentals: DNS, TLS, HTTP semantics, reverse proxies, load balancers. Scripting: Bash plus at least one of Python (or similar like Go/Ruby). Hands-on CI/CD pipeline design with any modern system. Production operations experience - you have been on-call, you have written postmortems, you have designed a capacity plan. Familiarity with at least one major cloud (AWS, GCP, or Azure) including its load-balancing, object-storage, and managed-database primitives. Git fluency. Experience using AI coding assistants and agent-based workflows in real ops work. Strong written English - runbooks, RFCs, and postmortems are core deliverables. Hard Skills - Nice-to-Have: Kubernetes operational experience (CKA welcome but not required). Terraform or Ansible at intermediate-or-deeper depth. Multi-cloud literacy — you have shipped on more than one of AWS, GCP, Azure. Observability stacks: Prometheus, Grafana, Loki, OpenTelemetry, Sentry. Database operations beyond CRUD: replication, point-in-time recovery, query tuning. IPFS or other content-addressable / peer-to-peer storage operational experience. Security hardening - OWASP, basic pen-testing literacy, secrets-management tooling (Vault, SOPS, AWS SM). Cost engineering - you have right-sized a cloud bill before. Cloud or Kubernetes certifications. Soft Skills: Calm under outages - you reach for tail -f before you reach for blame. Pragmatism: you can tell when introducing Kubernetes is correct and when it is yak-shaving. Documentation discipline - if it isn't in a runbook, it doesn't exist. Comfortable saying "no" or "not yet" to premature complexity. 📜 Our Promise (what you can expect from us): 30-33k PLN on B2B 100% remote work 300 PLN to use on our benefits platform, Worksmile - gift cards, medical services, sports, etc. Our B2B contract contains provisions that allow you to obtain IP BOX support Integration events, education opportunities and much more… A unique opportunity to take your career to the next level - we’re looking for people who want to create an impact.
