Job Description
About the role
\n
EHMA builds the software behind Everpower’s family of products. This is a broad role for an experienced backend engineer supporting multiple applications across our portfolio — from the high-volume APIs, third-party integrations, and data behind our B2B platform to a new battery and device fleet-management system. You’ll bring depth the current team can lean on, and work across our backend on a small, fast-moving team.
\n
\n
What you'll do
\n
• Build and maintain backend services and third-party integrations for our high-volume B2B platform — payments/financing, e-signature, CRM/ERP, and partner APIs.
\n
• Build resilient, idempotent integration flows — queues, webhooks, retries, and reconciliation — and keep business-critical data correct and auditable.
\n
• Help design and build our battery and device fleet-management platform — provisioning, over-the-air updates, remote configuration, monitoring, and telemetry at scale.
\n
• Build and operate connected-device / IoT data pipelines (device and battery telemetry).
\n
• Contribute to reliability and quality — automated tests, observability, and safe releases.
\n
\n
Where you’ll make an impact early
\n
• Adding much-needed capacity to our core B2B platform and its integrations.
\n
• Helping stand up the battery and device fleet-management backend.
\n
\n
What we're looking for
\n
• Several years of professional backend engineering with C#/.NET (ASP.NET Core) and Azure — enough depth to own designs, set patterns, and work independently.
\n
• Proven experience designing and operating third-party integrations and data pipelines at scale — queues / Service Bus, webhooks, retries, reconciliation, idempotency.
\n
• Experience with a document database (MongoDB / Cosmos DB) and a strong sense for data correctness and integrity.
\n
• Hands-on IoT / connected-device or fleet experience — ideally the Microsoft IoT stack (Azure IoT Hub, Device Provisioning Service, IoT Edge, Azure Digital Twins, or similar).
\n
• A quality mindset: tested, maintainable code and attention to reliability.
\n
\n
Nice to have
\n
• Payments, lending/financing, or e-signature integrations (Box Sign, DocuSign).
\n
• Battery management, energy systems, or embedded/hardware-adjacent experience.
\n
• Time-series / telemetry data at scale.
\n
• Observability with Application Insights / Azure Monitor / Log Analytics (KQL).
\n
- \n
- • iPaaS / integration middleware (Celigo / integrator.io or similar).
