Job summary

Jobgether, partnering with a client, is seeking a Software Engineer (Edge – Networking & Fleet) based in Spain. You will build and scale edge networking, fleet infrastructure and a scalable scheduling platform across Windows, Android, and Linux, contributing to reliable, production-grade systems for a large residential device network.

In a remote-first environment, you will own critical infrastructure, implement safe deployments, drive observability, and collaborate with distributed teams to

Qualifications

• 5+ years of professional Rust experience, including building, deploying, and operating production services end to end.
• Experience designing and operating distributed systems at scale ( schedulers, control planes, stateful services ).
• Strong understanding of distributed-systems concepts, including consistency, network partitions, backpressure, and idempotency.
• Deep networking knowledge covering TCP, TLS, HTTP, connection handshakes, and packet-level behavior.
• Practical experience with gRPC and long-lived connections across NAT environments and unreliable networks.
• Experience building or operating forward proxies, proxy gateways, or residential/ISP proxy infrastructure.
• Understanding of IP reputation, session stickiness, proxy pool health, and traffic routing.
• Production operations experience, including defining SLOs and error budgets, building observability, leading incident response, and participating in on-call rotations.
• Familiarity with cross-platform Rust development targeting Windows, Linux, and Android, including FFI boundaries where needed.
• Strong written communication skills and ability to collaborate effectively within a globally distributed, remote-first team.
• Curiosity, analytical thinking, and a practical approach to investigating system behavior under load and resolving underlying causes.

Responsibilities

• Scale the data plane with a scalable fetch scheduler capable of handling 50–100 million requests per day.
• Design and build the Fleet Manager control plane, including provider adapters, inventory and health management, configuration, reconciliation, software rollout control, and metrics export to BigQuery.
• Develop provider integrations that allow additional device sources to be onboarded through standardized workflows.
• Own and improve the CONNECT proxy gateway, edge session management, IP reputation, proxy leases, and request scheduling.
• Engineer secure and reliable networking between control services and residential peers using mTLS, gRPC, long-polling, and streaming over unreliable connections.
• Address networking challenges involving NAT, carrier-grade NAT, bandwidth accounting, and connection reliability.
• Define and maintain service-level objectives for availability, request success, and latency across the Edge route.
• Build observability and operational metrics covering peer availability, device drop-off, bandwidth usage, and provider performance.
• Implement safe blue/green deployments and software rollouts for control services and edge peers.
• Participate in the on-call rotation, lead incident post-mortems, and translate operational findings into improvements.
• Produce technical design documents and recommendations for scheduling, fleet management, and failover strategies.
• Review technical designs and promote distributed-systems best practices, including consistency, backpressure, idempotency, and limiting failure impact.
