Connectivity Engineer

About The Position

Dexory is hiring a Connectivity Engineer to help keep its global robot fleet connected over cellular, Wi-Fi, and mesh VPN, often on customer networks outside the company’s control. The role is focused on software, troubleshooting, and customer support rather than enterprise network infrastructure. It is based in Nashville, Tennessee, and is hybrid, with the split open for discussion. The position is permanent and calls for flexibility around customer needs, including occasional evening incidents because robots operate across multiple time zones. The engineer will handle customer-site connectivity cases from initial report through resolution, work with customer IT teams, diagnose network and application issues, commission routers, and validate sites before robot arrivals. They will build tooling, primarily in Go and shell, add monitoring and alerts, and help establish runbooks and incident processes. The role also includes visiting warehouse sites to test coverage and bring robots online, including UK sites and occasional international travel. The successful candidate will work alongside the engineer who designed and operates the current connectivity stack. After onboarding, they will become the first point of contact for connectivity cases and progressively develop expertise in cellular connectivity, mesh VPN design, challenging Wi-Fi environments, and Go tooling for a live fleet. With experience, they will take ownership of components such as router commissioning tools or fleet monitoring. Candidates are asked to include a short note about something technical they built, broke, or fixed and what they learned.

Requirements

Hands-on experience with networks, Linux systems, or deployed devices, gained through work or personal projects.
Comfort using a Linux command line.
Solid IP networking knowledge, including subnets, routing, NAT, DNS, DHCP, and firewalls.
Ability to use tcpdump or Wireshark to investigate where traffic stops.
Experience writing scripts or tools that other people have used, in any programming language, and willingness to work in Go.
Experience handling technical problems with customers or end users through support, field, or deployment work.
Methodical fault-finding habits, including keeping track of what has been tried.
Comfort working with ambiguity and helping shape processes.
Flexibility to respond to occasional evening incidents due to robots operating across several time zones.

Nice To Haves

Experience with mesh VPN products such as Tailscale, Netbird, Headscale, Netmaker, Nebula, or Defguard.
Experience with WireGuard, Tailscale, Nebula, or NetBird.
Experience with cellular modems and SIMs.
Wi-Fi knowledge beyond the basics.
Experience with Prometheus or Grafana.
Background supporting or operating networked systems at a telco or mobile operator, ISP, managed service provider, in IT support or IoT, or at another robotics company.
Personal technical projects or interests such as a home lab, self-hosted services, amateur radio, CTFs, or write-ups of problems solved.

Responsibilities

Own connectivity cases for customer sites from initial report through resolution, working directly with customer IT on firewall rules, port access, and Wi-Fi coverage.
Work with customers to solve connectivity issues and maintain active communication and follow-up.
Diagnose faults across cellular, Wi-Fi, VPN, and DNS, and determine whether the issue is with the network or the application.
Commission and configure routers for new sites and validate site networks before robots arrive.
Build and maintain tooling, mostly in Go and shell, to replace manual router setup and fleet-check steps.
Add monitoring and alerts for discovered issues so they can be caught before customers notice.
Write runbooks and help shape incident and escalation processes.
Visit warehouse sites to test coverage and bring robots online, including in the UK and occasionally abroad.
Progressively develop expertise in cellular connectivity, mesh VPN design, Wi-Fi in challenging RF environments, and Go tooling for a live fleet.
As experience builds, take ownership of parts of the connectivity stack, such as router commissioning tooling or fleet monitoring.
