Position summary

The Senior Operations Engineer is part of a small team acting as the technical reference for Stellar's operations. You provide advanced customer support, deliver proofs of concept (PoCs), present and demonstrate Stellar solutions, and drive the quality and depth of our operational practices.

Our solutions rely on a three-tier architecture: edge devices running embedded Linux that orchestrate traffic across WAN links (cellular, satellite, fibre, point-to-point, etc.), a gateway tier that terminates the multipath sessions (MPTCP, MPQUIC) and reassembles the traffic sent over those links, and a cloud-based management platform. Most field issues surface at the edge, and resolving them requires a solid understanding of the full chain, from the device to the gateway and the back-office. You will build and maintain this end-to-end understanding of the system.

This is a senior, hands-on role. You investigate in depth, dig into logs, traces, configurations and code, reproduce issues in the lab, and bring well-founded diagnostics to Engineering. You work closely with Engineering, Product and Sales to deploy, troubleshoot and demonstrate our solutions in real customer environments.

Key responsibilities

Advanced customer support: Own complex incidents involving infrastructure, applications, connectivity and Stellar products, from initial qualification through resolution. Keep customers informed and escalates to Engineering with a documented root-cause analysis.

In-depth investigation: Reproduce issues in the lab, analyse logs, packet captures, routing, tunnels, system metrics and source code (shell, Python) to identify root causes across the edge, gateway and management tiers.

Proofs of concept: Translate customer requirements into a defined scope, test plan and success criteria. Prepare, configure and deploy PoC environments, execute tests, analyse results and document conclusions and recommendations.

Technical presentations: Explain Stellar's architecture, capabilities and use cases to technical and non-technical audiences. Deliver product demonstrations and answer customer questions, clearly communicating prerequisites and limitations.

Device staging and deployment readiness: Working alongside logistics, stage hardware ahead of each customer delivery: flash and validate the right firmware, pre-provision devices, register them on the management platform and test them end to end so every unit ships production-ready. Install and configure edge devices, gateways, virtual machines and connectivity services, and support onboarding, upgrades and operational handovers.

Dedicated instance deployment: Deploy dedicated STEER® Management and STEER® Gateway instances, on Stellar-hosted VPS or on customer premises, using the deployment tooling provided by the DevOps team. Configure and validate each instance with the customer, lead on-site installations and run the instance in operation.

Customer training and enablement: Train customers across the full STEER® Suite (STEER® Edge, STEER® Gateway and STEER® Management) and its day-to-day use, and provide ongoing support as they roll out their fleet.

Documentation and knowledge base: Write and maintain customer-facing documentation, including API guides, user guides, a FAQ and an internal and external wiki, so customers and colleagues find answers on their own.

Technical reference: Act as the operations point of reference for Engineering, Product and Sales. Share knowledge, document recurring issues and help colleagues build their understanding of the system.

Operational excellence: Maintain lab and demonstration environments, contribute to product testing and release validation, and keep configurations, tickets and operational document
