Nethermind

Build and maintain backend telemetry services, APIs, and data models for connected devices and operational systems. | Strong backend development skills with experience in APIs, event pipelines, telemetry, and secure system design, plus domain knowledge in IoT or related fields. | Backend / Telemetry Engineer Nethermind is a blockchain research and software engineering company building high-performance infrastructure, security tooling, and cryptographic systems across the Ethereum ecosystem and beyond. We work closely with protocol teams, L2s, and ZK projects to help design, review, and secure cutting-edge decentralized systems. We are expanding our team and are looking for a Backend / Telemetry Engineer to build the cloud systems that support connected physical devices and real-world deployments. This is a backend role for someone who wants to work on machine data, events, fleet infrastructure, dashboards, APIs, and operational systems. Responsibilities: • Build backend services for telemetry, device state, events, dashboards, and partner integrations. • Design data models for machines, locations, users, events, status, diagnostics, and operational activity. • Build APIs for edge devices, internal tools, dashboards, and AI workflows. • Implement event ingestion pipelines, monitoring, alerting, and audit logs. • Work with embedded engineers on device-to-cloud protocols. • Work with product and business teams to define the data needed for demos, pilots, and customer reporting. • Support security, reliability, observability, and scalability from the beginning. Requirements: • Strong backend engineering experience. • Experience building production systems, APIs, databases, event pipelines, or telemetry platforms. • Strong programming ability in TypeScript, Python, Go, Java, Kotlin, Rust, or similar. • Experience with relational databases, time-series data, queues, event streaming, or cloud infrastructure. • Understanding of authentication, authorization, logging, monitoring, and secure system design. • English fluency required. Must Haves: • Experience with IoT, fleet management, retail technology, payments-adjacent systems, kiosks, robotics, or industrial systems. • Experience with high-volume event ingestion or real-time monitoring. • Experience with dashboards, analytics, alerting, field-service tools, or operational reporting. • Experience with transaction-like event flows, reconciliation, audit trails, or financial-grade data systems. Success in the first 90 days: • You build the first reliable telemetry backend for prototypes and pilots. • Devices can register, send events, report health, and expose useful data. • The team has clear data models and APIs. • You create observability that makes field debugging possible. Success in the first 6-12 months: • The backend supports multiple pilot environments and connected devices. • The platform can show machine status, operational events, diagnostics, and performance data. • You become a key owner of the data and telemetry platform. At Nethermind, we celebrate diversity and are committed to creating an inclusive environment for all team members. We believe a variety of perspectives drives innovation and leads to better solutions for the blockchain community.
