Senior Connectivity Engineer / Network Engineer

Senior Connectivity Engineer / Networking / VPN / Go / Python / Linux / Location: Wallingford - Oxfordshire (Hybrid) Permanent At Dexory, we are transforming the warehousing and logistics industry through data intelligence. We’re currently recruiting for a Senior Connectivity Engineer to take day-to-day ownership of the connectivity layer that keeps our global robot fleet online. You will build the tooling and automation that makes managing mesh VPN, industrial routers, Wi-Fi and cellular connectivity across the fleet fast, repeatable and observable. Offices are based in Wallingford, Oxford, with this role offered on a flexible hybrid basis (approximately once every 4 weeks on site). Experience in robotics, telematics, connected vehicles, industrial IoT, or start-up / scale-up environments is desirable, along with experience operating fleets of devices across multiple geographies and carriers. We’re open to candidates from a range of backgrounds - networking, platform, SRE, DevOps, embedded Linux, telematics - what matters is strong networking fundamentals paired with a tooling-first mindset. Responsibilities / Skills Own and evolve Dexory’s fleet connectivity stack (mesh VPN, routers, Wi-Fi, cellular) with a tooling-first, automation-led approach so we scale with the fleet, not headcount. Build internal tooling and self-serve workflows for router configuration/validation, access management, and fleet health checks; replace manual processes with repeatable, testable systems. Operate the mesh VPN layer (WireGuard/Tailscale or equivalent): access-as-code, policy patterns, posture/health automation, and resilience/disaster recovery planning. Deliver fleet-wide connectivity observability: monitoring, alerting, reporting, and actionable signals that help teams diagnose end-to-end issues quickly. Improve cellular/SIM lifecycle management: provisioning automation, usage/cost visibility, and carrier-level reporting. Enable deployments with pre-deployment network validation and simple site survey workflows that field teams can run independently. Partner with deployment, service and customer-facing teams to turn field issues into durable tooling and documentation, not recurring manual fixes. Strong networking fundamentals (routing, NAT, firewalls, DNS, VPNs, IPv4/IPv6) and experience operating production systems at scale; comfortable debugging multi-layer failures. Comfortable working close to the Linux networking stack when needed (interfaces, routing tables, MTU/PMTUD, conntrack, nftables/iptables) and diagnosing kernel-level networking behaviour. Proficient in Go and/or Python and experienced with modern observability tooling; bonus points for containers/IoT OS, ACL-as-code patterns, and carrier/router API integrations. #J-18808-Ljbffr
