Build platforms that power connectivity at national scale

At AllPoints Fibre Networks (APFN), we’re transforming how the UK connects. As a full‑fibre network wholesaler, we make high‑speed broadband simple, scalable and accessible — all through our API‑driven platform,
aquila
, which unifies major networks including Openreach, BT Wholesale and City Fibre.

We’re now looking for a Senior Platforms Engineer to play a key role in designing, running and improving the Linux, virtualisation and cloud platforms that underpin our services.

• Design, build and operate Linux‑first platforms supporting critical internal and ISP‑facing services

• Take ownership of our Proxmox virtualisation environment (with VMware as a legacy footprint)

• Engineer high‑availability, resilient architectures across on‑prem and AWS environments

• Build and maintain secure, observable hybrid connectivity between data centres and AWS

• Develop and evolve shared lab and test environments
  , enabling consistency, automation and self‑service

• Engineer AWS services with a focus on simplicity, uptime and operational readiness

• Design and support AWS networking, IAM and secure connectivity patterns

• Contribute to capacity planning, resilience testing and service transitions

• Lead automation using Python, Terraform and Ansible
  , reducing manual effort and risk

• Define and promote engineering standards
  , documentation and repeatable build patterns

• Improve observability and monitoring using tools such as Prometheus, Grafana, Zabbix, ELK and Graylog

• Ensure backup, recovery and resilience are engineered and regularly tested

• Act as a senior technical escalation point for complex issues

• Mentor and upskill engineers across Linux, AWS and automation

• Contribute to platform roadmaps and technical decisions aligned with business goals

• Produce clear design documentation and share knowledge across teams

• Participate in an on‑call rota
  , focusing on rapid recovery and long‑term preventative improvements

Essential experience

• Expert‑level Linux administration and troubleshooting

• Strong hands‑on experience with Proxmox / KVM / QEMU

• Practical AWS engineering experience (VPCs, IAM, hybrid connectivity, HA design)

• Automation and scripting expertise (
  Python preferred
  )

• IaC and configuration management (e.g.
  Terraform, Ansible
  )

• Solid networking fundamentals and secure integration patterns

• Experience operating monitoring and observability platforms

• Strong communication skills and a collaborative mindset

Nice to have

• Experience with ISP‑relevant platforms (e.g.
  Kea DHCP, Free RADIUS, Maria
  
  DB, Libre
  
  NMS, ELK
  )

• Knowledge of advanced routing protocols (BGP, OSPF)

• AWS hybrid networking (Direct Connect, VPNs)

• Experience designing lab or test environments

• Relevant certifications (AWS, Linux, networking, automation)

• Familiarity with XGS‑PON technologies (Adtran, Nokia)

We believe great engineering starts with well‑supported people. Our benefits include:

• 30 days’ annual leave (plus bank holidays)

• Bupa private medical & dental cover

• Income protection & group life insurance

• Health plan — yes, we’ll even pay for a massage

• Employer‑contributory pension & cost‑of‑living benefits

• A genuine commitment to Diversity, Equity & Inclusion
  , including Women in Telecoms, apprenticeships and mentoring

At APFN, we’re curious, ambitious and delivery‑focused. We move fast, support each other, and take pride in building platforms that genuinely make life easier for our partners.
