Hiring Team – 5G Systems GmbH
Vienna, Austria

Dear Hiring Team,

I am excited to apply for the Lead Engineer – Backend & Frontend position at 5G Systems. With 7+ years of hands‑on development in the real‑money gaming sector, deep expertise in sports‑betting and casino platforms, and a proven track record of leading high‑performing engineering squads, I am confident I can help drive the next wave of scalable, event‑driven solutions for Tipico’s ecosystem.

Why I’m a strong fit

• Domain expertise – I have spent the last [X] years building and maintaining betting‑exchange APIs, odds‑calculation engines, and casino‑game back‑ends for [Company A] and [Company B]. This includes compliance with multiple regulatory jurisdictions (e.g., Malta, UK, Germany) and integration with third‑party payment providers.
• Full‑stack leadership – As Tech Lead at [Current/Previous Company], I managed a cross‑functional team of [5‑10] engineers, introduced a micro‑services/event‑driven architecture using Kafka, Docker/Kubernetes, and Node.js/TypeScript on the backend, and React/Redux on the frontend. Our platform now handles >10 M concurrent users with sub‑second latency.
• Ownership & delivery – I championed a CI/CD pipeline (GitLab → Helm → K8s) that cut release cycles from weekly to daily, and instituted blameless post‑mortems that reduced production incidents by 30 %.
• Communication & collaboration – I regularly present technical road‑maps to product owners, translate business requirements into concrete engineering tasks, and mentor junior developers through pair‑programming and code‑review sessions.
• Cultural fit – Your values of Open Communication, Ownership, Humor, Innovation, and Teamwork resonate strongly with my own work style. I thrive in environments where ideas are shared openly, where we celebrate wins (and birthdays!) together, and where we constantly push the technical envelope.

What I can bring to 5G Systems

1. Scalable event‑driven platform – Design and rollout of a Kafka‑centric event bus to decouple betting‑logic, risk‑management, and UI services, enabling horizontal scaling and real‑time analytics.
2. Regulatory‑ready architecture – Implement audit‑trail logging, GDPR‑compliant data handling, and automated compliance checks across all services.
3. Team growth – Build a culture of continuous learning (tech‑talks, hack‑days, mentorship) while hiring and onboarding new talent to expand the squad to [desired size].
4. Hybrid‑working excellence – Establish clear async communication norms (Slack, Confluence) and regular in‑office collaboration days to keep the team aligned and energized.

I am eager to discuss how my experience aligns with 5G Systems’ vision and how we can together “write Gaming history from Austria.” Thank you for considering my application. I look forward to the possibility of meeting the team in Vienna.

Sincerely,

[Your Name]

Tip: Replace the bracketed placeholders with your actual data, and feel free to add any specific achievements (e.g., “Reduced latency by 45 % on the odds‑calculation service” or “Led a migration from monolith to micro‑services for a €30 M product line”).
