We learn on the floor
The problem is next to the line. Engineers who know PLC wiring and shift schedules find answers on real sites — proven in running plants, not demos.
KOPENS / CAREERS
People who know the floor
build the software for industry.
When our software stops, factories stop. KOPENS proves its work next to the line, not in a meeting room. From 42 protocols and 512,000 events per second to an on-premises industrial LLM — we're looking for people who solve real industrial problems in code.

A How we work
How we work
You own what you build
Small teams, big ownership. From design to deployment and operations, work doesn't leave your hands. You define the problem and finish it.
We speak in numbers
8ms ingest latency, 512,000 events per second, 1,674 automated tests. We prove quality with what's measurable, not adjectives.
We defend data sovereignty
Your data stays yours. On-premises tech that completes even in closed, air-gapped networks — we choose the hard right answer over the easy cloud.
B What you'll build
The tech you'll work with
One pipeline from sensor to AI — you build the whole line.
- Collect · Edge
- 42 industrial protocols (OPC-UA · MQTT · Modbus · SECS/GEM · IEC 61850 · DNP3), edge gateway, store-and-forward
- Real-time
- 512,000 events/s CEP, 8ms ingest latency, event & time-series DB, stream analytics
- AI
- On-prem industrial LLM, time-series anomaly detection, RAG, knowledge graph & ontology (ISA-95)
- Product · Web
- TypeScript, React, Astro, web SCADA canvas, no-code app builder
- Ops
- On-prem & air-gapped deploys, non-stop redundancy, 1,674 automated tests, container orchestration
C Roles
People we'd love to work with
These are areas we're growing. Even without a perfect opening, if you're serious about industrial data & AI, let's talk first.
01
Backend · Data Engineer
Large-scale real-time ingestion, stream processing, time-series storage. Pipelines that must not stop.
02
AI · ML Engineer
Industrial time-series models, on-prem LLMs, anomaly detection. AI that solves real problems on field data.
03
Frontend Engineer
Web SCADA, real-time dashboards, no-code builders. Turning dense industrial data into clear screens.
04
Field / Solutions Engineer
PLCs, protocols, on-site rollout. You finish the software on the customer's line.
05
Product Designer
Design restrained interfaces for the high-density information of the instrumentation domain.
06
Always open
Not on the list? That's fine. Where what you're great at meets what we need, a role gets made.
D Why here
What you get here
Industrial AI, for real
Electronics, shipbuilding, power, defense, aerospace — mission-critical domains you can't touch just anywhere.
End-to-end craft
From protocol drivers to LLMs, you own every layer of the product.
Autonomy & ownership
A team that runs on trust, not management. How to solve it is up to you.
Two homes
Changwon HQ and the Yongin R&D center — field and research, close together.
