● Build and maintain CI/CD pipelines and automation tools to accelerate releases and minimize risks during updates.

● Ensure fault tolerance, backup strategies, and disaster recovery plans.

● Monitor performance, implement logging systems, and respond promptly to incidents.

● Optimize infrastructure for minimal latency, high throughput, and cost efficiency.

● Collaborate with development, architecture, and security teams to implement DevOps best practices and improve system reliability.

● Ensure security measures and compliance with regulatory requirements (if necessary) in the DeFi space.

Requirements:

● Extensive experience with Kubernetes (deployment, configuration, scaling, and lifecycle management).

● Proficiency in automation tools such as Ansible, Terraform, Helm, Argo CD, and GitOps approaches.

● Experience building CI/CD pipelines (GitLab CI, GitHub Actions, Jenkins, etc.).

● Understanding of microservice architecture principles, network interaction in Kubernetes, and service mesh technologies.

● Experience integrating monitoring and logging systems (Prometheus, Grafana, Loki, ELK, OpenTelemetry).

● Understanding of DeFi project architecture and blockchain infrastructure specifics.

● Strong knowledge of infrastructure security, DDoS protection, and secrets/access management tools (e.g., HashiCorp Vault, KMS).

Soft Skills:

● Ability to work independently, make decisions, and manage time effectively.

● Proactive problem-solving approach, with the ability to suggest and implement improvements.

● Strong interpersonal skills to work effectively with distributed teams.

● Flexibility and adaptability to fast-paced, ever-changing environments and new technologies.

Nice to have:

● Experience with blockchain node setup and operations (Ethereum or other popular blockchains), with a strong understanding of node operations, P2P protocols, and indexing processes.

● Web3 Decentralization Guardians.

We Offer:

● The opportunity to work on innovative projects in the DeFi and blockchain space.

● Professional and career growth opportunities in a rapidly evolving industry.
