Job description

What you’ll do

• Build and maintain backend services and third-party integrations for our high-volume B2B platform — payments/financing, e-signature, CRM/ERP, and partner APIs.
• Build resilient, idempotent integration flows — queues, webhooks, retries, and reconciliation — and keep business‑critical data correct and auditable.
• Help design and build our battery and device fleet‑management platform — provisioning, over‑the‑air updates, remote configuration, monitoring, and telemetry at scale.
• Build and operate connected‑device / IoT data pipelines (device and battery telemetry).
• Contribute to reliability and quality — automated tests, observability, and safe releases.

Where you’ll make an impact early

• Adding much‑needed capacity to our core B2B platform and its integrations.
• Helping stand up the battery and device fleet‑management backend.

What we’re looking for

• Several years of professional backend engineering with C#/.NET (ASP.NET Core) and Azure — enough depth to own designs, set patterns, and work independently.
• Proven experience designing and operating third‑party integrations and data pipelines at scale — queues / Service Bus, webhooks, retries, reconciliation, idempotency.
• Experience with a document database (MongoDB / Cosmos DB) and a strong sense for data correctness and integrity.
• 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).
• A quality mindset: tested, maintainable code and attention to reliability.

Nice to have

• Payments, lending/financing, or e‑signature integrations (Box Sign, DocuSign).
• Battery management, energy systems, or embedded/hardware‑adjacent experience.
• Time‑series / telemetry data at scale.
• Observability with Application Insights / Azure Monitor / Log Analytics (KQL).
• iPaaS / integration middleware (Celigo / integrator.io or similar).
