Digital Systems Developer (AI-Augmented)

We are hiring a developer to work directly alongside our technical lead and Claude, the AI we use every day as a working collaborator. This is not a “we use Copilot for autocomplete” role. Claude designs, writes and reviews production code with us; your job is to direct that work, judge it, integrate it and ship it. If you have already found that pairing with an AI makes you far more productive - and you want to do that all day, on systems that real customers and staff depend on - this is the role.

What you will do

• Turn operational problems (“orders stall here”, “billing files don’t reconcile”, “staff re-key this three times”) into specified, working systems - fast.

• Pair with Claude to design, build, test and harden new BSS modules and integrations, then take ownership of getting them live.

• Work against wholesale and carrier APIs (broadband aggregators, Openreach-based suppliers, One Touch Switch, mobile SIM management) - SOAP, XML, REST and JWT auth, often with thin or wrong documentation.

• Build internal tooling that changes how the business operates: automation of manual processes, dashboards, reconciliation engines, customer self-service, and the odd AI-driven feature (we already run an AI first-responder in our ticket system).

• Deploy and look after what you build on our Plesk-managed VPS hosting.

• Review AI-generated code critically: security, edge cases, data integrity and performance are yours to sign off, not the model’s.

• Ship in small, frequent increments across our family of brands.

• Improve and enhance what is built to ensure we are ahead of the game.

Our stack

• PHP 8.3+, PDO, MariaDB - framework-free, minimal dependencies
• Vanilla JavaScript, HTML/CSS; no build pipeline
• Plesk-managed VPS hosting, nginx, zip deployment
• Integrations via SOAP, REST/JSON, Microsoft Graph, Stripe, GoCardless, Royal Mail
• Claude (Anthropic) as the day-to-day development partner

Practical backend web development and relational database experience - you can design a schema, write the queries and make them fast.

• Real experience using AI coding assistants to build production software, and clear opinions on where they help and where they get it wrong.

• Comfortable working with third-party APIs, including badly documented ones, and debugging by reading the wire.

• Security-minded: auth, sessions, CSRF, input handling and personal data are second nature.

• Able to take a loosely described business problem and turn it into a scoped, buildable spec - you will often be the one writing the brief for Claude.

• Right to work in the UK; fluent written British English.

Desirable

• Knowledge of PHP (plain, framework-free) and MariaDB/MySQL.

• Experience administering or deploying to a Plesk-managed VPS.

• Telecoms or ISP background (broadband provisioning, Openreach/wholesale processes, billing and reconciliation, One Touch Switch).

• WordPress plugin development.

• Experience with TM Forum APIs, CDR pipelines or TR-069/ACS.

• Experience with data reconciliation or duplicate-detection logic.
