Systems & AI Developer (ID: QHRB2mj5)

In-House Developer – AI, Automation & Software Development - Salary: £40,000–£50,000 per year - Location: In person - Barwell, Leicestershire (LE9)

About the role

• We're serious about using technology and AI to work smarter, eliminate unnecessary admin and build a more efficient business. Now, we're looking for our first in-house developer to help make that happen.
• This is an opportunity to take ownership of our technology from the ground up. Rather than inheriting someone else's systems or spending your days fixing minor issues, you'll have the freedom to identify problems, develop solutions and build tools that make a real difference to how our business operates.
• You'll work directly with our directors, estimators, surveyors and office team, turning real business challenges into practical software, intelligent automation and better ways of working.
• You'll have the opportunity to shape our entire technology strategy and see the results of your work being used every day.

What you'll be doing

This is a hands-on development role with plenty of scope to take ideas from concept through to implementation.

• Connect our systems: Integrate our core business platforms, including Priceworx, accounts, email and merchant data, so information flows seamlessly without manual re-keying.
• Build AI-powered automation: Use tools such as Claude and its API to automate repetitive processes. One of the first projects will be matching supplier invoices against purchase orders and improving our procurement processes.
• Develop our own estimating software: Design and build an in-house system that converts house types, specifications and project requirements into accurate material and labour costs.
• Improve business reporting: Create better visibility of costs, margins, purchasing and progress across individual sites and plots.
• Make our team more productive: Identify opportunities to use technology and AI to reduce administration, improve accuracy and streamline everyday tasks.
• Support and develop the team: Introduce new tools, train staff and document the systems you build so the whole business can benefit.

What we're looking for

We're interested in what you can actually build and how you approach solving problems, not just the qualifications on your CV.

You'll ideally have:

• Strong practical development experience in Python and/or JavaScript.
• Experience working with databases and building applications.
• Hands-on experience using AI tools and APIs, ideally the Claude API.
• Experience integrating business systems through APIs.
• Familiarity with automation platforms such as Make, Zapier or n8n.
• A practical, problem-solving mindset and the ability to take projects from idea to finished product.
• The confidence to work directly with non-technical colleagues and explain technical concepts in plain English.
• An interest in understanding how a business operates, rather than simply writing code to a specification.
• Most importantly, you should enjoy finding better ways of doing things and have the initiative to make them happen.

Desirable experience

• Experience in construction, plumbing, trades or new-build housing.
• Previous involvement in building estimating, quoting, procurement or job management software.
• Experience working with financial, accounting or merchant systems.
• A portfolio of applications, automations or tools you've built to solve real business problems.

What we offer

• Salary of £40,000–£50,000, depending on experience.
• Company pension.
• Laptop and tools provided.
• A genuine opportunity to build our technology function from scratch.
• Direct access to the directors and the freedom to influence business decisions.
• Real ownership of projects, with the opportunity to see your ideas implemented across the business.

This is a chance to become a key part of the business as we invest in technology, AI and automation to support our next stage of growth.

How to Apply

• Alongside your CV, please include a short note telling us about something you've built that you're particularly proud of. Ideally, we'd like to hear about a tool, application or automation that solved a genuine business problem.
• Shortlisted candidates will be invited to complete a short, paid practical task so we can see how they approach real-world problems.
