Job Type: Permanent, Full Time
About Hagerty Digital
At Hagerty Digital, we’re expanding our Systems & Integrations team to support a major long-term client transformation programme. This is an opportunity to join a growing agency and play a key role in delivering complex, business-critical technology projects.
We’re looking for either a Senior Developer ready to take the next step into a leadership position, or an experienced Lead Developer / Systems Engineer who enjoys taking ownership of technical solutions from design through to delivery.
The Role
You’ll lead the technical delivery of a significant systems transformation programme involving CRM implementation, systems integration, custom middleware development, and, in the near future, a large-scale ERP migration.
Working closely with our internal development team, leadership, and the client, you’ll help define technical architecture, guide a small team of developers, and ensure multiple business systems work seamlessly together.
This is a hands-on technical role with genuine ownership and the opportunity to shape long-term solutions.
We will also be inheriting a Coollogic Android app being built on native Java in the near future as part of this project.
Key Responsibilities
- Lead and mentor a small systems and software development team
- Design, build and maintain custom middleware and system integrations
- Work extensively with SQL-based databases and business systems
- Integrate CRM, telephony, accounting software and other third-party platforms using APIs
- Support wider full-stack development where required
- Collaborate with stakeholders to translate business requirements into technical solutions
- Help modernise and migrate legacy platforms into a newly managed environment
- Take technical ownership of a future ERP implementation and integration project
- Support Hagerty Digital’s wider development team on selected client projects
About You
We’re looking for someone with a strong technical background who enjoys solving complex integration challenges and can confidently lead technical delivery.
Ideally you’ll have:
- Strong hands-on SQL experience
- A solid full-stack development background
- Experience designing and developing APIs, integrations and middleware
- Experience working with CRM, ERP or other business-critical systems
- The ability to understand, modernise and integrate legacy platforms
- Good knowledge of HTML, CSS, JavaScript and modern web technologies
- Exposure to Magento or other ecommerce platforms (desirable, not essential)
- Previous experience working within an agency or other fast-paced project environment
- The confidence to take technical ownership and support less experienced developers
- Around five years’ commercial development experience
Why Join Us?
This role would suit someone who enjoys untangling complex technical problems, working across multiple interconnected systems, and playing a leading role in delivering large-scale digital transformation projects.
You’ll have the opportunity to influence architecture, work directly with senior stakeholders, and help shape the future direction of a growing Systems & Integrations function within Hagerty Digital.
Working Pattern
This is primarily an office-based role from our Warmley, Bristol office, with flexibility where appropriate. Occasional travel to client or vendor sites may be required as part of project delivery.
Pay: £45,000.00-£60,000.00 per year
Work Location: In person
