Job Description

About the role

Check out the role overview below If you are confident you have got the right skills and experience, apply today.

This is an on-site role, based in Southend. Please only apply if you are comfortable working from the office Monday to Friday.

We are looking for a practical, capable Web Developer to join a small and growing development business working across a mixture of client websites, bespoke web applications and ongoing technical support.

Our work is varied. Some days you may be developing a new feature for a bespoke PHP application; others may involve improving an existing website, investigating a database issue, fixing a deployment problem or helping to maintain the Linux hosting environment behind a project.

Web development will be the main focus of the role, but we are looking for someone who is comfortable working beyond the front end and understands how websites, databases, servers and DNS fit together.

We work closely alongside a range of businesses requiring website development, maintenance and technical support.

This is a permanent position with room to take ownership of projects, expand your skills and become an important part of a small technical team.

What you will be doing

  • Developing and maintaining websites and bespoke web applications

Building new features using PHP, MySQL, HTML, CSS and JavaScript

Working on existing systems built with frameworks such as Laravel and CodeIgniter

Investigating and fixing bugs in both new and legacy code

Designing, writing and optimising MySQL or MariaDB queries

Integrating websites and applications with third-party APIs

Maintaining and improving existing client websites

Supporting WordPress websites where required

Deploying code and database changes to development and production environments

Diagnosing website, email, DNS, SSL and hosting-related issues

Carrying out basic Linux and web-server administration

Communicating clearly about progress, technical problems and proposed solutions

Working directly with clients and non-technical colleagues when required

Usage of Claude/Codex where appropriate to facilitate speed, however strong core understanding of what you are producing is essential

Essential skills

You do not need to have worked with every technology we use, but you should have a solid foundation in web development and be willing to learn.

You should have experience with:

  • PHP

MySQL or MariaDB

HTML and CSS

JavaScript

Git

Building, maintaining or supporting database-driven websites

Debugging existing code and identifying the cause of technical problems

Writing clear, maintainable code

Working independently and managing your own workload

A good understanding of relational database design is important. Whilst it will be largely unnecessary due to the frameworks we use, you should be comfortable writing joins, filtering and grouping data, working with indexes and investigating slow or incorrect queries.

Server and hosting knowledge

This is primarily a development role, but some basic server-management experience is required.

You should be comfortable with at least some of the following:

  • Linux command-line environments

Apache or Nginx

cPanel or WHM

File permissions and ownership

DNS records

SSL certificates

Email-delivery troubleshooting

Reading server and application logs

Using SSH, rsync and command-line tools

Basic deployment and backup procedures

You will not be expected to be a dedicated systems administrator, but you should be confident investigating why a website or application is not working rather than treating the server as a black box.

Desirable experience

Experience with any of the following would be beneficial:

  • Laravel

CodeIgniter

WordPress development

REST APIs

Docker or containerised development environments

Node.js

jQuery or existing JavaScript codebases

Linux server administration

cPanel hosting environments

Performance optimisation

Website migrations

Email authentication, including SPF, DKIM and DMARC

Cloud services or virtual servers

Automated testing

CI/CD or deployment pipelines

What we are looking for

We are a business starting out, and flexible regarding formal experience and qualifications. You may be an established developer, someone earlier in their career with strong practical skills, or a self-taught developer who can demonstrate good-quality work.

More important to us is that you:

  • Approach problems logically

Take responsibility for seeing work through

Are comfortable working with existing and sometimes imperfect code

Know when to investigate independently and when to ask for help

Communicate clearly and honestly

Pay attention to detail

Understand the importance of backups, testing and safe changes

Are interested in how the whole system works, not just the section of code immediately in front of you

We are not looking for someone who only builds pages using visual website builders. You should be comfortable working directly with code and databases.

What we offer

  • A permanent, full-time position

Varied work across websites, bespoke systems and infrastructure

The opportunity to take ownership of meaningful projects

Exposure to both modern and established codebases

Support from an experienced developer with more than 25 years in the industry

The opportunity to broaden your development and server-management skills

A relaxed, practical working environment without unnecessary corporate processes

Scope for the role to grow around your strengths

How to apply

Please send us:

  • Your CV

A brief introduction explaining your current experience

Links to any relevant websites, applications, GitHub repositories or portfolio work

Details of the parts of web development you are most confident with

Your current notice period and salary expectations

We welcome applications from candidates with different levels of commercial experience. xwwtmva Evidence of practical ability, sound judgement and a willingness to learn will be considered alongside years spent in previous roles.
