Senior Platform Engineer

The Codest, an international tech software company with a focus on web development, cloud engineering, DevOps, and quality, is seeking a Senior Platform Engineer to manage and scale their self-hosted production system and help grow their infrastructure capabilities.

Location: Remote

Salary: 30-34k B2B

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.

Requirements

• 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.

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