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? Apply or get in touch: | linkedin.com/in/jirisoljak No CV needed — a LinkedIn profile and a few sentences about yourself is enough. You'll speak directly with a senior IT recruiter with hands-on IT background — 450+ hires. A relevant conversation without the HR fluff. Process: — Short intro call (15–30 min) — Maximum 2 rounds — if there's a fit, a decision can come after the first one — In-person meeting before the final decision — You'll know where you stand at every step EU work authorization required.

160.000 - 200.000 CZK

An international technology group with more than 30 years in the market, 800+ professionals, and a presence across several countries in Central and Eastern Europe. It delivers projects in IT infrastructure, data centres, cloud, cybersecurity and IT outsourcing for customers ranging from banking and public administration to European enterprise organisations. Why This Role Exists Now: Regulatory pressure, NIS2 in particular, is pushing organisations toward segmented, auditable networks. Microsegmentation and identity-based access are becoming baseline requirements, and the volume of enterprise network engagements has grown accordingly. That architecture layer is currently covered on an ad hoc basis — by the presales team or by drawing on capacity from elsewhere in the group. The company is building a permanent capability instead.What Matters Most: - CCNP Enterprise Architecture or equivalent - certification at architectural, not implementation, level - Minimum 5 years in enterprise network design - demonstrable experience across switching, routing, microsegmentation and security - Software-defined networking and automation - conceptual command is required; hands-on implementation is not - Consultative capability - the ability to present and defend a design to a customer stakeholder is a condition of the role, not an advantage English at B2/C1 for the international team; Czech or Slovak for day-to-day work. Nice to Have: - CCNP Data Center or CCNP Security - Cloud or multi-cloud experience - TOGAF or ArchiMate - Practical involvement in lab work or proof-of-concept builds These describe the working context, not selection criteria.Role / Mission: You own the architecture of enterprise network and data centre solutions for large customers — from initial concept through customer-facing validation to oversight during implementation. You work alongside the internal presales team, and when a design change becomes necessary during implementation, you adapt the concept rather than handing it off. Within twelve months, the expectation is a set of delivered engagements, established relationships with the customers you have worked with, and a working model with presales that moves designs into delivery without unnecessary iteration. Key Responsibilities: - Design and optimise enterprise networks — LAN, WAN and SD-WAN — for large-scale customer environments - Present and defend technical solutions directly to customers in consultative settings - Work with presales and sales on accounts you subsequently deliver - Govern design changes during implementation, maintaining the integrity of the original concept - Coordinate with service providers on configuration standards; review Bill of Materials and assess solution sizing What This Role Is NOT: - Not an implementation role — configuration delivery sits with the engineering team - Not a hand-off model — architectural ownership continues into implementation, not concluding at design sign-off - Not a back-office technical function — customer-facing consultation is central to the role, not adjacent to it Operating Model: Prague-based, hybrid. On-site presence with customers at least twice a week; the majority of the customer base is in and around Prague. More time in the office during onboarding, with greater flexibility thereafter. English at B2/C1 for the international team; Czech or Slovak for day-to-day work. Direct report: Head of Network & Security division. Options: The engagement model is open to discussion: - Permanent employment - 160 000-180 000 CZK/month with a company car - Contract (self-employed) - day rate up to 11 000 CZK, agreed individually - Reduced capacity - four days per week is acceptable under either model for the right profileInterested? Apply or reach out — no CV needed, your LinkedIn and a few lines is enough. We reply to everyone within two business days. | linkedin.com/in/jirisoljak You will speak directly with a senior IT recruiter with a hands-on technical background — a relevant conversation without the HR fluff.
