The project:

We are looking for an experienced Senior 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.

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 todays 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 Youll Work With or Introduce:

• Docker Docker Compose image building.

• Linux (Debian-style) Bash Python for scripting.

• Lighttpd today (niche with DB-driven vhost logic youll learn) - likely to be reconsidered as we scale.

• MariaDB - including replication backup/restore drills performance tuning.

• Kubo IPFS node private-swarm operation gateway scaling.

• Lets 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 isnt in a runbook it doesnt exist.

• Comfortable saying no or not yet to premature complexity.

Our offer:

• Salary: 30-34k on B2B

• 100% remote work (full-time or part-time)

• 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 - were looking for people who want to create an impact. You have ideas we want to hear them!
