Job description

CiviCRM / PHP Engineer (Mid-level to Senior)

A big hello from the team at Compuco!

At Compucow empowering socially responsible organisations with the digital tools they need to build a better world.

As a data driven creative technology agency, we are passionate about helping membership, charitable and cultural organisations to streamline and reimagine the way they work so that they can focus on impact.

We are looking for an experienced PHP engineer to build and maintain CiviCRM extensions and Drupal modules for not-for-profit clients. You will use AI coding tools every day and care about testing.

Compucow is split into product teams. As a key member of one of these teams, you'll be involved in the entire development process, from the specification phase through to release. Your main focus will be building new functionality as CiviCRM extensions and Drupal modules (Drupal 7 and Drupal 10/11), around finances, payments, memberships and case management. We use AI coding tools every day and have shared playbooks for how to use them. We expect you to use them to work faster, and to check what they produce before it reaches a reviewer.

We’re a very process-driven team and constantly seek to refine the way we work to ensure that we continue to deliver the highest quality service to our clients and to the sector as a whole. We’re looking for someone with a “can do” attitude to join our growing team.

As a distributed company with an HQ in London and team members from all around the world, one of the things that makes working at Compuco special is the chance to meet, mix and learn from people from an amazing array of nationalities and cultures. We’re extremely proud of the way we work and the open culture we’ve developed.

Key responsibilities:

• Build and test CiviCRM extensions and Drupal modules, with unit tests on every change
• Help write technical specifications before building, and at a senior level lead them
• Review other people’s pull requests and give useful technical feedback
• Use AI coding tools within our playbooks, and check their output
• Investigate production issues to the root cause and write up what you found
• Take part in planning, estimation and retrospectives, and follow actions through
• Keep documentation up to date: README files, extension metadata, process pages
• Share knowledge with and support other members of the team

Experience sought:

• At least 3 years of experience in web application development with PHP. For the senior end of the range, we look for 5+ years, including time as a senior or lead.
• Experience extending a large PHP platform through its hooks, APIs and modules or plugins (Drupal, WordPress, SuiteCRM, Magento or similar). CiviCRM experience is a bonus
• Daily use of AI coding tools (Claude Code, Codex, Gemini CLI, Cursor or similar) on real projects, and the judgement to spot when their output is wrong
• Experience writing unit tests and testing processes
• Excellent database / SQL skills, including performance optimisation and normalisation
• Be skilled with Git, including rebasing and squashing commits
• Experience with Docker-based local development environments
• Experience with Linux and the command line
• Experience with CI/CD pipelines, ideally GitHub Actions

What we value in this role:

1. Good judgement: knowing when the quick answer is the wrong answer, whether it comes from an AI tool or a person
2. Following through: a job is done when the fix is merged and the ticket is closed
3. Clear writing: specifications, PR descriptions and investigation notes that others can act on
4. Team player: reviews, mentors and shares by default

Type: Permanent

Location: Hybrid working (office based in Shoreditch, London) or Fully Remote anywhere in the world

Salary range: £25k-£35k
