Macstab GmbH Wir bauen Systeme die wirklich performen.
Lead/Principal+ Level Engineers für platform, identity & performance — Kubernetes, Terraform, GitOps, Istio traffic shifting (canary/blue-green), SLO/SLA + error budgets, OAuth2/OIDC/SAML token lifecycle, observability-as-code, profiling-driven latency budgets (p99/p999). Zero-downtime patterns (stateless); near-zero / downtime-minimized migrations (stateful + DB, where feasible).
Seit 2009 liefern wir produktive Enterprise-Systeme – inklusive 10M+ Logins/Tag im Peak im regulierten Banking, SLO/SLA-getriebene Zuverlässigkeit im hohen 99er-Bereich (systemabhängig) und Zero-/Near-Zero-Downtime-Rollouts, wo es machbar ist.
Engineering Excellence
Nicht „nur Code“. Wir designen, shippen und operieren Systeme unter echten Constraints: Regulierung, auditability, Performance-Budgets und sichere Rollouts.
High-Performance Backend
Java, Kotlin, Go, Rust. Maintainable Microservices, event-driven architecture, CQRS wenn es passt — gebaut für throughput, correctness und operability.
Cloud-Native Platform
Kubernetes, Terraform, AWS/Azure/GCP. Production clusters, GitOps, Istio traffic shifting (canary/blue-green), graceful shutdown, connection draining — zero-downtime patterns für stateless; near-zero / downtime-minimized cutovers für stateful + DB (where feasible).
Identity & Security
OAuth2, OIDC, SAML. Secure auth flows, token lifecycle (rotation/revocation), session correlation, policy-driven access, Zero Trust patterns — audit-friendly by design für regulierte Umgebungen.
3D & Gaming Tech
Unity, Unreal, WebGL. Echtzeit-Multiplayer-Backends. Physik-Simulationen. Wir bauen immersive Erlebnisse, die Hardware-Limits sprengen.
Performance Engineering
Profiling-first optimization: perf budgets (p99/p999), cold start/startup, memory, CPU, I/O — measured, tuned, validated under load.
Strategische Beratung
Architecture reviews, delivery playbooks, Migrationsstrategie und technische Entscheidungen — hands-on, production-focused, sauber dokumentiert.
Battle-Tested Stack
Technologien, die wir shipped und in production operated haben (at scale)
Reliability & Delivery Playbook
SLO-driven engineering, progressive delivery, and operational guardrails — designed to survive production reality.
Progressive delivery (Istio)
Canary/blue-green traffic shifting, request routing, connection draining, and safe rollbacks — zero-downtime patterns for stateless services.
Stateful + DB migrations
Expand–migrate–contract, online schema changes, CDC-based cutovers, rolling upgrades, controlled failover — near-zero / downtime-minimized where feasible.
Observability guardrails
Golden signals (RED/USE), SLOs + error budgets, tracing, alert hygiene, load tests, chaos experiments — rollouts gated by metrics.
Security & compliance-by-design
OAuth2/OIDC hardening, token lifecycle, least privilege, audit trails, policy-as-code — built for regulated environments.
Echte Ergebnisse. Echte Produktion.
Ausgewählte Outcomes aus Enterprise-Engagements (Details anonymisiert)
In einem regulierten Enterprise-Banking-Programm: über 10 Millionen Authentifizierungen pro Tag im Peak (z. B. zum Jahreswechsel).
Cache round-trips reduziert und den read/write path gestrafft — messbar höherer Durchsatz und niedrigere Latenz in production-nahen Load-Tests.
Ausgelegt auf auditability: least privilege, traceability, policy-as-code und compliance-friendly logging/retention patterns.
