We are looking for a Technical Support Manager to build and lead the support organization from the ground up. You will be the first operations hire — responsible for assembling the team, designing processes, setting up tools, and launching 24/7 support operations. 

You will manage two teams: 

- Technical Operations Engineers — L2-level technical specialists handling platform monitoring, incident response, and API troubleshooting. 

- L1 Support Specialists — first-line support handling triage, basic troubleshooting, and ticket routing.

This is a hands-on leadership role for someone who enjoys building from zero, not just managing what already exists.

Position Requirements

Must have:

• 3-5 years of experience in technical support or IT operations, with at least 1-2 years in a Team Lead or Manager role.
• Hands-on experience building support processes from scratch.
• Experience managing 24/7 shift-based teams — scheduling, rotation, burnout prevention.
• Understanding of incident management frameworks (ITIL, PagerDuty/Opsgenie workflows, SLA design).
• Technical depth sufficient to mentor L2-level engineers: REST API debugging, log analysis, basic SQL, monitoring dashboards.
• Experience hiring and onboarding technical staff across different seniority levels.
• Strong written and verbal communication skills.
• Fluent Ukrainian and English (C1+).

Nice to have:

• iGaming, fintech, or payments industry experience.
• Experience with B2B support models (SLA-driven, operator/client-facing).
• Familiarity with compliance-regulated environments (ISO 27001, PCI DSS).

• ITIL Foundation or similar certification.

  
  Responsibilities

• Build, hire, and lead a team of ~9 people (L1 Support + Technical Operations Engineers).
• Design the full support process: ticket lifecycle, triage rules, escalation matrix, SLA framework.
• Manage 24/7 shift schedules and ensure sustainable rotation for the team.
• Own the incident management process: classification, escalation paths, post-incident reviews.
• Build and maintain a runbook library for consistent incident response.
• Set up support tooling: ticketing system, knowledge base, status page, monitoring dashboards.
• Define and track operational KPIs: First Contact Resolution, MTTA, MTTR, SLA compliance.
• Coordinate with DevOps and Engineering teams on escalations and infrastructure issues.
• Provide regular operational reports to leadership.
  
  We offer
• 25 days off per year + official holidays off
• Military reservist deferment
• English lessons compensation
• Medical compensation
