Senior engineering for what has to ship.
Generated code is the easy part. We bring the architecture, integration and production ownership a model can't hold — for several DAX 40 companies and the SMEs who move the DACH economy.
SME to DAX 40 — range is the proof, not size.
RANGE
DAX 40 + SME
Engineering partner for several DAX 40 companies and SMEs across DACH. We fit both ends of the market, not just one.
STACK
OPC-UA · MQTT · Kafka
One coherent pipeline from sensor to event stream. Scala, Rust, Go, and Python for data science — cloud-native on Kubernetes.
TRUST
BSI IT-Grundschutz
Certified by Germany's Federal Office for Information Security — full-company scope, based on ISO 27001. AWS Select Partner. EU-hosted.
UPTIME
9-5 → 24/7
SLAs that match the severity of the system. Many of our builds are still in production years later — operated by us, or handed over to the customer.
Why Core exists
We started Core Technologies because the problems we wanted to work on fell into a gap — too ambitious for generic dev shops, too integrated for industrial integrators, and now too consequential to hand to a model. The AI era hasn't made judgment less valuable. It's made it the whole game. We built the team that brings it: senior engineers who ship production systems, and who can sit in a room with a CFO, a plant manager, or a board and talk about the business in its own language — then go write the code that moves those numbers.
01.
Judgment, not code.
We use AI to go faster. We ship decisions, not generated output.
02.
Seniors ship.
Every engineer has 8+ years behind them. No pyramid, nowhere to hide, nowhere to coast.
03.
Build to harden.
Demos are easy. Second-year systems are hard. We build for the second year.
04.
Fluent in the business.
Unit economics, OEE, platform risk — whatever your language, our engineers speak it. Then they write the code.
Small by design. Senior by default.
8+.
years, every senior — no juniors on the line
Europe.
remote-first, HQ Essen, EU data residency
End-to-end.
edge → cloud → LLM in production
01.
Edge & Gateway
Fleet, OTA, device identity, offline-first.
02.
Platform & SaaS
Multi-tenant, billing, auth, observability from day one.
03.
Industrial Data
OT ↔ IT bridges, time-series at scale, sensor fusion.
04.
LLM in Production
RAG and tool-use integration for existing platforms. Evals, cost controls, guard-rails.
05.
Observability & SRE
SLOs, tracing, incident discipline, post-mortems that change code.
06.
Cloud-Native Architecture
Event-driven on Kafka, microservices on Kubernetes — our bread and butter, from the first commit.
07.
Own Edge Hardware
We build our own intelligent edge gateway for industrial data ingestion — separate landing page follows.
08.
Regulated Delivery
GDPR, ISO-aligned change control, audit-ready from the first commit.
No names, no photos, no AI-generated faces. The count on screen is capabilities — not engineers. See /privacy.
Where the work has gone.
ENERGY
Trading-floor automation inside several major European energy traders.
INDUSTRIAL
Asset-optimization systems across industrial, manufacturing, and energy operations.
DAX 40
Customer-facing products shipped for DAX 40 companies.
We're selective about when we hire.
If you're a senior engineer who ships — edge, platform, or production AI — we want to hear from you, even when we're not actively recruiting.
Put us in a room with your hardest system.
Send a line, or book 30 minutes. Either way you get an engineer, not an account manager.
