Senior DevOps / Infrastructure Engineer
Vacancy Description
We are building and operating infrastructure for a broad blockchain ecosystem, including a wallet infrastructure, stablecoin products, and supporting financial services. We are looking for a senior DevOps / Infrastructure Engineer who can help design, maintain, and scale secure production environments across cloud and on-premise setups.
The role combines hands-on infrastructure engineering, operational support, reliability planning, incident response, and coordination across multiple technical and business stakeholders.
Requirements
-
7+ years of professional experience in infrastructure support, infrastructure engineering, DevOps, SRE, or platform engineering.
-
Deep understanding of Microsoft Azure, including hands-on production experience with its core infrastructure, networking, security, compute, storage, and managed service offerings.
-
Experience with on-premise infrastructure, including environments with and without Kubernetes.
-
Strong hands-on experience with Kubernetes and containerized workloads, including production operations, troubleshooting, scaling, and maintenance.
-
Experience with modern delivery tooling, including GitHub or GitLab, CI/CD pipelines, Argo CD, and related automation practices.
-
Strong understanding of infrastructure-as-code practices, preferably with Terraform.
-
Solid understanding of network architecture, including segmentation, segregation, VPNs, routing, DNS, load balancing, NSGs, firewalls, private connectivity, and secure access patterns.
-
Experience with security practices and the ability to interpret and implement compliance requirements in infrastructure and operational processes.
-
Experience maintaining infrastructure for financial systems or other high-reliability, regulated, or business-critical platforms.
-
Strong experience with monitoring, logging, observability, alerting, and traceability using modern stacks such as Prometheus, Grafana, Loki, ELK/OpenSearch, OpenTelemetry, or similar tools.
-
Understanding of RTO, RPO, backup strategies, restore procedures, failover planning, and their practical implications for system design.
-
Proven experience participating in on-call rotations, incident response, post-incident reviews, and operational improvements.
-
Hands-on participation in infrastructure planning, reliability planning, disaster recovery planning, and failover testing.
-
Strong communication skills, with the ability to coordinate infrastructure work involving multiple teams, vendors, clients, and stakeholders with different levels of technical understanding.
-
Ability to identify infrastructure and operational risks early, explain trade-offs clearly, and drive mitigation actions to completion.
Would be a plus
- Experience with platform engineering tools such as Kargo, Crossplane, Backstage, or similar tools that improve developer experience and operational consistency.
- Experience maintaining HSMs, especially Thales or similar enterprise-grade key management solutions.
- Experience with secure execution environments such as SGX, Nitro Enclaves, or similar technologies.
- Hands-on experience with blockchain infrastructure, Web3 systems, rollups, smart contracts, validators, sequencers, nodes, bridges, or related components.
- Experience supporting multiple concurrent projects or environments with different priorities, risk levels, and operational requirements.
- Ability to communicate effectively with technical and non-technical stakeholders
Responsibilities
-
Design, maintain, and improve production infrastructure across Azure, on-premise, and hybrid environments.
-
Plan and operate Kubernetes-based and non-Kubernetes infrastructure depending on project needs.
-
Build and maintain CI/CD and GitOps workflows using GitHub/GitLab CI, Argo CD, and related tools.
-
Develop and maintain infrastructure-as-code modules for reproducible and auditable environments.
-
Define and maintain network, compute, storage, access control, and security configurations for production and pre-production systems.
-
Implement and improve monitoring, logging, alerting, tracing, and operational visibility across services and infrastructure components.
-
Support backup, restore, disaster recovery, and failover planning, including practical validation of RTO and RPO assumptions.
-
Participate in incident response, on-call escalation, root cause analysis, and follow-up remediation.
-
Help project teams resolve infrastructure, deployment, networking, security, and reliability issues.
-
Participate in infrastructure planning for new systems, releases, migrations, integrations, and production launches.
-
Translate compliance, security, and operational requirements into practical infrastructure changes.
-
Coordinate operational work involving engineering teams, delivery teams, vendors, clients, and other stakeholders.
-
Evaluate and introduce tools or practices that improve reliability, security, delivery speed, or operational maintainability.
