Key job responsibilities
Own the entity lifecycle APIs — create, provision, power-on, and tear down virtual satellites, gateways, customer terminals, and antennas — and drive them to and past a 99.9% availability bar
Design and evolve the orchestration layer: long-running state machines that coordinate provisioning across distributed dependencies where any step can fail on physics rather than code, and where partial failure must be recoverable rather than restart-from-scratch
Own the service-side plugin framework — the published contract, registration, delegation, and result aggregation that lets subsystem owner teams define their own initialization, health validation, and provisioning logic without our team in the loop
Build the health check aggregation API: a single call that returns per-subsystem health with every failure attributed to the team that owns it, so customers self-diagnose instead of paging an on-call
Build and own continuous canaries that validate the full stack against a pre-production constellation on a fixed schedule, wired so that a failure cuts a ticket and pages automatically with no human in the detection path
Integrate with certificate, identity, and entity-registry services — device identity generation at constellation scale, certificate lifecycle, namespace registration, and the calibration data that makes a virtual entity behave like its physical twin
Drive down provisioning latency, currently measured in minutes at p90, through parallelization, image pre-baking, and eliminating serialized dependencies
Own observability end to end — structured logging, embedded metrics, distributed tracing, and log centralization — with the specific goal that a customer can root-cause a failed run from logs alone without recreating it
Scale the platform for concurrent multi-tenant use: capacity management across bare-metal pools, fleet-wide provisioning throughput, and cost per simulated entity
Partner closely with the virtualization and emulation team that owns the host layer, with subsystem owner teams who build against your plugin contract, and with the test frameworks and release pipelines that are your highest-volume customers
A day in the life
This role is for a Software Development Engineer who will build new cloud services and APIs that manage customer devices such as applying software updates, telemetry, and self-healing. You will be building low-latency, highly scalable architecture that are critical to getting high quality internet service to customers.
About the team
You will join the VirtSat Platform team within Leo Developer Experience. The team owns VirtSat end to end — the simulation service control plane, the virtualization host layer, fidelity of the emulated subsystems, and adoption across Leo.
This role sits on the services side of that boundary. You will own the simulation service: its public APIs, its provisioning workflows, its plugin framework, its canaries and health checks, and its availability and latency posture. A sibling role owns the bare-metal virtualization layer beneath you; you own the contract between them.
