IT Technical Architect

Vivacom, a member of United Group, is a leader in providing high-tech telecommunication services. Our large IT department delivers cutting-edge software solutions to support Vivacom’s business.

We are changing how we build software. Our teams own their systems end to end, and every team works with AI agents that help them design, code, test and operate. We are looking for a Technical Architect who will be hands-on with the engineering teams. The role makes AI-assisted development safe, fast and consistent across the department.

The benefits of being part of the team:

Compensation package

• Attractive salary based on your performance
• Monthly food vouchers – €52
• Device voucher – €312
• SIM card with an Unlimited plan
• No cap on bonuses under the “Refer a Friend” program
• Preferential conditions for Vivacom services for you and your loved ones

Work–Life Balance

• 3 extra days if you use up your entire annual paid leave
• 1 day off for your birthday
• Flexible working hours
• Hybrid working model depending on the position
• Additional health insurance for you and your family
• Co-financed sports card
• Discounts at over 100 great places – shops, restaurants, hotels

Not just a job. Growth.

• Personal mentor and access to an interactive e-learning platform
• A real career development plan

What you will do

• Set the technical standards for the department (languages, frameworks, APIs, security, observability) and turn them into templates, reference implementations and automated checks in CI.
• Design the AI-assisted engineering setup: coding and review agents, approved skills, ai.md rules per repository, approved MCP integrations, and the guardrails that keep agents away from production data and changes.
• Lead the code review community and own the review standards, so that AI-generated code is reviewed harder, not less.
• Work with Platform Engineering & SRE on the delivery pipeline: CI/CD, GitOps, Kubernetes, quality and security gates, and the metrics that show whether AI helps or hurts (review queue time, pipeline wait, defect escape).
• Support the domain teams in solution design: API contracts (TM Forum Open APIs), integration and event patterns, data access and non-functional requirements.
• Guide the modernisation of legacy systems: use AI to understand and document old code, write characterisation tests, and replace legacy step by step behind clear interfaces.
• Prototype and evaluate new AI tools and approaches, and say clearly what works and what doesn’t.
• Take part in the Architecture Review Board for technical decisions and record deviations as ADRs

What we are looking for?

• 5+ years of hands-on software engineering, with at least 2 years in a technical lead or architect role.
• Strong coding skills in at least one of Java, .NET, TypeScript/Node.js or Python. You read and review code every week.
• Practical experience building software with AI: coding assistants and agents, LLM APIs, prompt and context design, RAG, evaluation of AI output, and an understanding of AI security risks (prompt injection, data leakage).
• Experience with containers and Kubernetes, CI/CD and GitOps.
• Good understanding of API-first and event-driven architecture, microservices and integration patterns.
• Experience with relational and NoSQL databases.
• A pragmatic mindset: you can tell an assertion from a demonstrated fact and explain trade-offs to engineers and managers.
• Good English and the ability to write clear technical standards and decisions.
• A university degree is welcome but not required. We value proven experience and what you have built.

Nice to have:

• Experience in telecoms or with BSS/OSS systems; TM Forum Open APIs or ODA.
• Experience with MCP servers, agent frameworks or building internal developer platforms.
• Experience modernising legacy code (C++, PL/SQL) with AI assistance.
• Kubernetes or cloud certifications (CKA/CKAD, AWS/Azure/GCP), security certifications.
• Open-source contributions or a portfolio you can show us.
