Our almost 1,000-person team builds tools that make work better for the three billion frontline workers who keep the world moving. We've got big tech scale, without the sign-off layers or corporate theatre. Every permanent team member gets equity, so when we grow, you do too. This next chapter is about scaling smart, powered by AI, a clear vision and real ownership.\nBig tech impact, without the big tech ick.\nRole Purpose\nThis role exists to build Mitti's hybrid network, connecting our existing Amazon Web Services (AWS) and Google Cloud Platform (GCP) environments to a new physical colocation (colo) facility, and connecting that facility to the internet through our own multi-homed network. It's a greenfield build that starts with research and development (R&D) workloads, so we can prove the foundation before production follows. It's also a software engineering role: the automation built here has to scale from one site to a global footprint, so network and hardware operations are treated as a software problem from day one.\nThis is the first hire into a new team. You'll be primarily a specialist across networking and a generalist across infrastructure rather than a deep network only specialist, and this is not a people leadership role.\nNot in scope: application-level reliability and service level objectives, sole ownership of the on-premises Kubernetes platform, and corporate IT. These are owned or shared with other teams.\nKey Responsibilities\nDesign, build and operate Mitti's multi-homed internet edge using Border Gateway Protocol (BGP) with multiple carriers, so traffic moves predictably and losing a path is a non-event.\n\nDesign and run the data centre fabric: an Ethernet Virtual Private Network (EVPN) control plane over Virtual Extensible LAN (VXLAN) overlays with equal-cost multi-path (ECMP) forwarding, so the network scales horizontally and predictably.\n\nConnect AWS and GCP to the physical network with a routed, secure path (interconnect, transit design, Virtual Private Cloud integration, Domain Name System, load balancing and IP address management), defined in code and reproducible. Use it to prepare for a production integration with AWS & GCP.\n\nContribute to enabling Mitti's own routed Internet Protocol (IP) address space, including address and Autonomous System Number (ASN) allocation through the relevant Regional Internet Registry, announcement, peering and route origin validation, and migrate traffic without disruption.\n\nBuild the automation layer for network and hardware operations (provisioning, configuration, validation and change management as code), starting at one site but designed for a global footprint.\n\nContribute to standing up on-premises Kubernetes on physical hardware with the Cloud Infrastructure Team, owning the network and hardware layer it runs on.\n\nContribute to the colo environment build: hardware selection, cabling standards, out-of-band management, hardware lifecycle and supplier relationships. The physical build is straightforward and infrequent, so the emphasis is on the network.\n\nMake the estate observable and self-service with the Observability team, and write the designs, standards and runbooks that the team that follows will need.\n\nRequired Skills & Experience\nTechnical Skills\nProduction experience running a multi-homed BGP network, including peering and sessions with providers, traffic engineering and path selection, and diagnosing issues such as link flapping.\n\nStrong IP networking fundamentals and packet-level debugging (Wireshark or equivalent).\n\nDesigning and troubleshooting an EVPN/VXLAN overlay fabric with ECMP multipath forwarding.\n\nStrong Linux system administration, including comfort treating network devices as Linux systems. Experience with open network operating systems such as SONiC is a strong advantage.\n\nWorking knowledge of Kubernetes, especially networking (Container Network Interface plugins, services, ingress and load balancer integration) in self-managed or bare-metal environments. We'd welcome someone whose strength is Kubernetes and who is keen to go deeper into networking.\n\nThe ability to write working Python or Go to automate network and infrastructure tasks. Experience with Terraform and Ansible is a plus. Our backend teams work in Go, and the Cloud Infrastructure Team's Kubernetes work leans on it too.\n\nExperience building or operating cloud network architecture in AWS or GCP (VPC design, transit routing, private connectivity, VPNs).\n\nHands-on familiarity with physical infrastructure (racking, cabling, power, out-of-band management through Baseboard Management Controllers). Experience with enterprise or data centre network vendors (Arista, Juniper, Cisco or similar) is helpful, and we're open to people willing to learn.\n\nA plus, not a prerequisite: public internet routing (Regional Internet Registry allocation, Resource Public Key Infrastructure and route origin validation) and kernel-bypass networking (Vector Packet Processing, Data Plane Development Kit).\n\nBehavioural Skills\nLoves a blank sheet. Gets energy from building something from scratch rather than inheriting it, and makes decisions with incomplete information, revisiting them as evidence comes in.\n\nSelf-directed. Works out what needs to happen next, drives it with minimal direction, and defers decisions until the evidence is in.\n\nExperiments properly. Builds a virtual lab, forms a hypothesis, tests it, documents the result, and treats cost as an engineering input.\n\nScrappy and cost-conscious. Finds practical, economical ways to get things done rather than waiting for a full toolset, which suits a build where we start small and expand.\n\nBuilds with others, not at them. Works with the engineers who'll use the automation, takes code review seriously in both directions, and treats the Cloud Infrastructure Team as a customer.\n\nReceptive to feedback and open about mistakes. Mistakes during the R&D phase are expected and safe to make. You'll own them, learn from them and share what you learned.\n\nKnows when to pull in help. Brings in specialists in Cloud Infrastructure, Observability, Security or backend engineering rather than pushing on alone.\n\nAI Skills\nUses AI tools every day for infrastructure code, automation and runbooks, including bootstrapping and validating device configurations, with sound judgement about when not to trust the output in a change-controlled network.\n\nUses AI to speed up research and to investigate network incidents, for example correlating logs, events and observability signals, and builds small AI-assisted automations (alert enrichment, inventory parsing, first-draft configurations).\n\nMinimum expectation: a fluent, everyday user of AI tooling for engineering work.\n\nSuccess Looks Like\nWithin about six months, a first network is standing and has been reviewed and re-architected where needed. Mitti has a multi-homed internet edge with multiple carriers, running BGP.\n\nAWS and GCP are connected to the live colo facility over a routed path that is designed, documented and reproducible from code.\n\nThe first colo site is running R&D workloads on an EVPN/VXLAN/ECMP fabric that is documented, instrumented and tested for failure behaviour.\n\nOn-premises Kubernetes is running R&D workloads for the Cloud Infrastructure Team, and the network and hardware layer is solid enough that no one is worrying about it.\n\nNetwork and hardware operations run through automation that other engineers use and extend, and the design holds up when a second site is added. This gives leadership the evidence it needs to decide on bringing production workloads in.\n\nKey Stakeholders\nCloud Infrastructure Team (primary internal customer and on-premises Kubernetes partner)\n\nEngineering Manager, Platform (direct manager)\n\nEngineering Director (mentor and stakeholder for the colo and hardware scope)\n\nSite Reliability Engineering, Platform, Observability and backend (Go) engineers\n\nSecurity Engineering, Finance and Procurement, Corporate IT\n\nExternal: the colo provider, network carriers, hardware suppliers and the Regional Internet Registry\n\nMore than a job\nEquity with high growth potential, and a competitive salary\n\nFlexible working arrangements\n\nAccess to professional and personal training and development opportunities\n\nHackathons, Workshops, Lunch & Learns\n\nOffice benefits\nIn-house Culinary Crew serving up daily breakfast, lunch and snacks\n\nBarista coffee machine, craft beer on tap, boutique wines and a range of non-alcoholic beverages\n\nWellbeing initiatives such as EAP services and generous parental leave policy\n\nQuarterly celebrations and team events\n\nOn-site gym, table tennis, board games, books library, and pet-friendly offices\n\nWe’re committed to building inclusive teams and cultivating a sense of belonging so our people can bring their whole authentic selves to work each day.
