The posting

🌍 Hello World!

We are The Codest - International Tech Software Company with tech hubs in Poland delivering global IT solutions and projects. Our core values lie in “Customers and People First” approach that prioritises the needs of our customers and a collaborative environment for our employees, enabling us to deliver exceptional products and services.

Our expertise centers on web development, cloud engineering, DevOps and quality. After many years of developing our own product - Yieldbird, which was honored as a laureate of the prestigious Top25 Deloitte awards, we arrived at our mission: to help tech companies build impactful product and scale their IT teams through boosting IT delivery performance. Through our extensive experience with product development challenges, we have become experts in building digital products and scaling IT teams.

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 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 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 offer:

  • Salary: 30-33k on B2B
  • 100% remote work (full-time or part-time)
  • A unique opportunity to take your career to the next level - we’re looking for people who want to create an impact. You have ideas, we want to hear them!

📌Recruitment process:

  • 30 minute screening call online with our recruiter, Justyna
  • Interview with CTO
  • 1h technical interview
  • Interview with CEO

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.
