Graphdex.io

GraphDex is a trading terminal for Solana, Base, and other EVM-based networks. We already have real users and integrations with decentralized exchanges (DEXs), and now we are expanding our team.

Format: Full-time, remote/hybrid

Project stack: 20+ microservices (Rust, Python/FastAPI, Go), Docker, Helm, K3s/K8s, PostgreSQL, Redis, RabbitMQ, Prometheus/Grafana, GitOps, Terraform, The Graph subgraph, multi-repo/monorepo.

Responsibilities

• Deploy and maintain 20+ microservices.
• Manage and update Helm charts and values.yaml.
• Maintain observability: configure SLO/SLI, investigate incidents, conduct postmortems.
• Manage releases across dev/stage/prod, implement GitOps processes.
• Operate Kubernetes/K3s clusters: upgrades, security, scaling.
• Monitor and maintain PostgreSQL, Redis, RabbitMQ.
• Capacity planning, cost and performance optimization.
• Perform regular backups, test disaster recovery procedures.
• Automate CI/CD, accelerate pipelines, implement quality gates.
• Develop Infrastructure as Code (Terraform), ensure modularity, conduct code reviews.
• Set up monitoring and alerting (Prometheus, Grafana, Alertmanager).

• Maintain documentation, create runbooks, train the team.

   

Requirements

• 3–5+ years of DevOps/SRE experience in production environments.
• Strong expertise in Kubernetes/K3s, cluster management, Helm.
• Production-grade experience with Terraform (modules, state management, pipelines).
• CI/CD and GitOps (ArgoCD/FluxCD or similar).
• Linux administration, diagnostics, performance tuning.
• Experience with Docker, container images, and container security.
• PostgreSQL, Redis: replication, backups, tuning.
• Prometheus/Grafana: exporters, metrics, alerting.
• Experience with multi-cloud or hybrid solutions.
• HashiCorp Vault or similar, VPN, certificates.

• Scripting and automation (Python/Bash).

   

Nice to have

• Experience operating RabbitMQ (clustering, HA, monitoring).
• Knowledge of network policies and service meshes (CNI, Ingress, mTLS).
• Experience with The Graph/subgraphs and Web3 stack.

• Container and cluster security practices (OPA/Gatekeeper/PSP/PodSecurity).

   

What we offer:

• Remote collaboration without bureaucracy
• A strong technical team that values clean code and healthy communication
• Challenging tasks at the crossroads of Web3, blockchain, and high-load systems
