Senior/Lead Backend Engineer

You will own the design, development, and operation of critical backend systems, working across AI infrastructure, energy data, billing, and trading technologies to deliver reliable and scalable solutions.

• Design, build, and maintain complex backend systems from initial architecture and implementation through production deployment and ongoing optimization.

• Develop the inference layer supporting AI workloads, serving millions of prompts per day across customer support and meter-reading optical character recognition (OCR).

• Migrate AI workloads to proprietary GPU infrastructure, improving control over performance, scalability, and computing resources.

• Build systems that process energy settlement data, supporting continuous recalculation as new information becomes available, even months after energy delivery.

• Develop and enhance real-time billing infrastructure, including per-customer transaction ordering, idempotency, audit trails, and pricing based on half-hourly meter readings.

• Build and extend energy trading and hedging systems supporting forward markets, portfolio optimization, and reconciliation with directly accessed exchanges.

• Ensure backend services meet high standards for availability, reliability, scalability, and data integrity.

• Collaborate closely with product teams to translate business requirements into effective technical architectures and production-ready solutions.

• Take ownership of technical decisions, identify system improvements, and deliver complex engineering projects with a high degree of autonomy.
