Salary

75.000 - 110.000 CZK

International technology group with 30+ years in the market, 800+ professionals, and offices across Central and Eastern Europe. They deliver projects in IT infrastructure, data centres, cloud solutions, and cybersecurity. The company is growing — clients are expanding their demand, new projects are coming in, and there's space for new competencies. The Cyber Security / IAM division currently works heavily with the IdStory platform, but the environment includes other IAM/IDM solutions too. They need someone who can handle the full cycle from analysis to implementation. Why This Role Exists Now: Client demand for identity security is growing. The IAM division is expanding its project portfolio and needs someone who can own the full delivery cycle — from analysis through architecture to go-live. There's space for new competencies and platforms beyond IdStory. The right person can shape what the IAM practice looks like going forward.What Matters Most: — IAM/IDM experience — minimum 3–5 years in IT security / IAM. Real implementation experience, not just operations — IAM platforms — IdStory, SailPoint, One Identity, Entra ID, Okta, or similar. Knowing one superficially isn't enough — Client-facing communication — analysis, consultations, presenting solutions. This is non-negotiable — Integration and APIs — REST, SOAP, GraphQL. You know how to connect systems Fluent Czech or Slovak required. English at a level where you can handle a normal working discussion. Nice to Have: — SQL and databases — you work with data, not just look at GUIs — Scripting (Groovy, PowerShell, Python) — Basic Linux knowledge — Identity governance concepts and identity lifecycle management — Experience with HR systems and their integration with IAM These are nice to have — not hard filters.Role / Mission: You own the full cycle — from the first client workshop through architecture to go-live. You walk into a client's environment, map what's actually there, ask the right questions, pull the data together into a document, and design a new architecture. Then you implement it. You're an analyst and implementer in one — not someone who waits for a spec. After 12 months, this is what good looks like: completed projects, clients who trust you, and working identity integrations in real environments. Key Responsibilities: — You analyse customer requirements and design IAM/IDM architecture — You implement and integrate identity solutions into client environments — You handle incidents and operational support within SLA — not as the core of your work, but as part of it — You create technical documentation — actually useful materials, not formal paperwork — You provide technical consultations to clients — You contribute to presales — solution proposals, presentations, technical input for bids — You work with sales, presales, support, and delivery teams What This Role Is NOT: — Not AD administration — you won't be resetting passwords and creating accounts — Not a pure operations role — SLA tickets are part of the job, but not the core — Not an isolated position — client and team communication is key Operating Model: Prague-based, remote-friendly. More time in the office during onboarding. After that, remote is possible — but you're expected at the office or client sites as needed. Most of the business is in and around Prague, so a reasonable commute matters. No 24/7 on-call. Permanent contract preferred, freelance possible. Czech or Slovak proficiency required. Direct report: Head of Network & Security division.More Information: Interested?

International technology group with 30+ years in the market, 800+ professionals, and offices across Central and Eastern Europe. They deliver projects in IT infrastructure, data centres, cloud solutions, and cybersecurity. The company is growing — new projects, new clients, expanding demand. The Network & Security division runs a team of 20 engineers across Cisco, Checkpoint, Palo Alto, and Fortinet. Fortinet projects are picking up and the team needs someone who can take that capability to the next level. This is a place where you build and implement, not just operate. WHY THIS ROLE EXISTS NOW: The company is growing and Fortinet projects are expanding. The team currently has two mid-level Fortinet engineers — they need an L3 who can own the capability, drive delivery, and set standards. There's a clear gap: strong demand from clients, growing project pipeline, but no senior Fortinet specialist to lead it.What Matters Most: — Fortinet hands-on — strong experience with FortiGate, NGFW, VPN, IPS. Fortinet is the primary vendor here, not one of many — Minimum 5 years in network security — design, implementation, service. Not just monitoring — Client-facing communication — you can present solutions, consult, and defend a proposal. This is non-negotiable — Security concepts — NGFW, NAC, SASE, SD-WAN, WAF. You understand them, not just list them Fluent Czech or Slovak required. English at a level where you can handle a normal working discussion. Nice to Have: — Experience with Cisco or Palo Alto (the team works with these vendors too) — FCP, CCNP, or PCNSE certification — Cloud deployments (AWS/Azure) and IaaC principles — Python for automation — University degree These are nice to have — not hard filters.Role / Mission: You're coming in as the strongest Fortinet person on the team. The team is a mix of juniors, mids, and seniors across platforms — right now there are two people working with Fortinet at a mid level. You're L3, the one who drives it forward. You design solutions for clients, you're the technical authority in presentations and consultations, and you pull the heavier delivery. After 12 months, this is what good looks like: a stabilised Fortinet practice in the team, completed projects, and clients who know you by name. For a top profile, there's a natural path toward technical leadership of the Fortinet part — but first and foremost, they need someone who's strong technically and can communicate. Key Responsibilities: — You design, implement, and service network security solutions — primarily Fortinet (FortiGate, FortiManager, FortiAnalyzer) — You're the L3 escalation point for the team — you handle what others can't yet — You communicate directly with clients — technical presentations, consultations, solution proposals — You work with presales and sales — you help sell what you'll then build — You contribute to cloud-based Fortinet deployments (AWS/Azure) — You share know-how with the team — you set standards and help juniors and mids grow What This Role Is NOT: — Not pure operations — you won't spend your days on tickets and routine maintenance — Not a management role — you don't formally manage people, but you lead them technically — Not isolated work — without client and team communication, this doesn't work Operating Model: Prague-based, remote-friendly. More time in the office during onboarding. After that, remote is possible — but you're expected at the office or client sites as needed. Most of the business is in and around Prague, so a reasonable commute matters. Permanent contract preferred, freelance possible for the right profile. Standard L3 on-call rotation within the team.
