About the role

We are hiring a Head of Infrastructure.

Our infrastructure is not one production. We run a legacy SaaS on bare-metal, a new SaaS on AWS (Kubernetes, Terraform), client on-prem installations in AWS, and we may deploy into client data centers or private clouds. All of this must work at 99.9%+ SLA under ISO 27001, PCI DSS and MiCA requirements.
We also run our own blockchain node farm with its own reliability requirements.

You lead the Infrastructure department (~40 engineers, 5-7 teams): strategy, people, platform and reliability. You are the technical leader engineers follow, and the person who owns infrastructure commitments to the CTO, product teams, Security and clients.

YOUR FIRST 6-12 MONTHS

• Finish the transformation of the infrastructure org into a layered structure (infrastructure as a service, platform/services, SRE, blockchain, internal IT). Keep key people, change what does not work.
• Build a platform to manage many environments: one source of truth for what version runs where, release policies per environment (SaaS on demand, bank on-prem with strict control), self-service for developers.
• Make SRE/L3 fully own observability and incidents for all productions.
• Complete the migration from legacy bare-metal SaaS to AWS and decommission the legacy.
• Raise the engineering and hiring bar in the department.

Job description

• Set infrastructure strategy for 1-3 years, quarterly goals and roadmap.
• Build and develop the team: structure, hiring, growth of team leads.
• Own change management, incident management and release processes across all environments.
• Approve target SLA/SLO; lead investigation of major incidents.
• Align infrastructure with Security, compliance, product teams and clients.
• Own infrastructure budget and vendor relationships.
• Report status and risks to the CTO and top management.

Required

• 7+ years in infrastructure / platform / SRE / DevOps.
• 2+ years leading an infrastructure organization through team leads (3+ teams, 10+ engineers).
• Strong technical background. You can review architecture, find weak points and explain to senior engineers why a solution will not work at our scale. Daily hands-on work is not expected, but your technical opinion must be respected by engineers.
• Experience running many environments or installations: versioning, rollout strategy, isolation, configuration drift.
• Experience with both bare-metal and cloud (AWS preferred), Kubernetes, IaC, observability, networking.
• Ownership of reliability: SLA/SLO, incident management, post-mortems, change discipline.
• Clear communication with CTO-level stakeholders: priorities, trade-offs, risks.
• High hiring bar. You hire people stronger than yourself.

Highly preferred

• Experience in regulated environments (fintech, banking, payments): ISO 27001, PCI DSS, SOC 2 or similar.
• Experience with client on-prem deployments, including environments with limited or no direct access.
• Track record of measurable results: MTTR, uptime, cost reduction, deployment speed.
• Built an org with clear roles: team leads, tech leads / principal engineers, service ownership.
• FinOps: cost attribution and optimization with real numbers.

Nice to have

• Blockchain node infrastructure (RPC nodes, validators).
• DR/BCP at department level (RTO/RPO).
• Internal developer platform experience (Backstage or similar).
