Berlin (Hybrid / On-site) | Full-time | 5+ years experience | Loadwise.ai About LoadwiseData centers are becoming one of the fastest-growing electricity consumers in history, especially AI and HPC clusters. Power systems are increasingly driven by renewable generation, creating volatility in prices, carbon intensity, and grid conditions. Loadwise builds software that allows compute infrastructure to respond intelligently to these energy signals. The RoleWe are looking for a Platform & Integration Engineer to build the Loadwise platform. This is the core software engineering role on the team. You will own ingestion, external connections, backend services, and production infrastructure; work closely with Energy Systems and Controls Engineering; and be the technical point of contact for customer engineering teams. What the first six months look likeBy month six, the platform is ingesting live telemetry from pilot facilities via at least two industrial protocols, integrated with one external energy market signal feed, and serving a real-time backend API to the controls and forecasting stack. All services are fully instrumented with metrics, logging, and alerting. What You'll Work OnProtocol Adapters & Integrations: Build and maintain protocol adapters to facility infrastructure and building automation systems; connect to energy market APIs and grid operator feeds; build interfaces for real-time and forward-looking compute workload demand visibility.Platform & Backend Services: Build reliable data ingestion pipelines (validation, transformation, storage); design and maintain backend APIs; implement data normalization and schema management; ensure pipelines handle reconnection, backfill, and partial failures gracefully.Reliability & Observability: Instrument services with metrics, logging, and alerting; define and track data freshness, completeness, and quality SLAs; own deployment, scaling, and operational runbooks. What We're Looking ForBackend Engineering & Systems: Experience building backend services and data pipelines; strong in Python or TypeScript/JavaScript (Go also works); comfort with distributed systems; familiarity with event-driven architectures, message queues, or streaming systems (Kafka, NATS, or similar).Infrastructure & Operations: Deploying/operating services in Kubernetes; observability tooling (Prometheus, Grafana); fault tolerance, retry logic, graceful degradation; CI/CD and GitOps.Tools & Mindset: Treat AI-assisted development tools as force multipliers; operate as a senior IC with broad ownership; navigate vendor docs and proprietary APIs; clear communicator.Nice to Have: IoT/industrial protocols (BACnet, Modbus, MQTT, OPC-UA); simple operator dashboards (React/Vue); experience with DCIM/BMS vendors; experience with energy market APIs or grid interfaces. What We OfferCompetitive Base & Meaningful Equity; Relocation & Visa Support (Berlin, hybrid/on-site); Your Setup (licenses, top hardware); High Autonomy, Zero Bureaucracy; Our Process: Three stages, no more than four weeks from first call to offer.
