##### YOUR IMPACT AT UMH
Build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container, processing millions of industrial messages that control actual production processes.
**What you will do:**
* Industrial-Scale Stream Processing: Architect systems handling 50+ protocol converters (OPC UA, Modbus, S7, MQTT) running concurrently in resource-constrained edge environments
* Unified Namespace Architecture: Design APIs and data flows connecting PLCs, sensors, ERP/MES systems into one coherent “Unified Namespace” using Redpanda (Kafka-compatible)
* Edge-to-Cloud Pipeline: Build robust data pipelines that survive network outages, buffer locally, and guarantee message delivery for mission-critical factory operations
* Debug distributed systems issues across industrial protocols, edge devices, and cloud infrastructure.
* Fast shipping with safety nets - PRs to production in <24h through automated testing, code reviews, and staged rollouts.
* Open Source at Scale: Contribute to github.com/united-manufacturing-hub
* Close collaboration with Customer Success and the user community via Discord, Slack, Linear, and GitHub
* Tech Stack: Go, Svelte, Typescript
##### YOUR PROFILE
* Proven track record of solving complex bugs, with evidence such as post-mortem, blog post, or PR link
* Experience in early-stage startup environments (small teams, high autonomy)
* 3–5 years of professional software engineering experience
* Examples of product ownership from idea to measurable success
* Active contributions to open-source projects
* Practical use of AI tools in development
* Ideally familiarity with IT/OT protocols (MQTT, OPC UA) or Industrial IoT
