Software Developer

Job Description

Location: Somerset

Job Type: Permanent

Clearance: N/A

We are seeking a Software Developer to join a highly collaborative, agile development team that values creativity, autonomy, and shared responsibility. Working within a flat structure, you’ll engage in pair programming, whiteboarding, and joint architecture design, ensuring every line of code is peer-reviewed. Collaboration is at the heart of this role, extending across product owners, account managers, and operations teams to deliver exceptional customer experiences and maintain application stability. You’ll participate in sprint planning, contribute to a culture of continuous learning, and help drive value through Scrum practices. To succeed, you’ll need commercial experience with modern programming languages (PHP, JavaScript, React, or similar), a solid understanding of MVC or modern JavaScript frameworks, and familiarity with Git. Strong communication skills and comfort with collaborative coding are essential. Experience with accessibility standards, testing frameworks, and software design best practices is desirable, but a willingness to learn and grow is just as important. If you’re passionate about technology and thrive in a supportive, team-driven environment, we’d love to hear from you.

To be able to do this, we process the IP addresses of visitors to the website. When someone visits our website, we collect information to monitor and report on the effectiveness of the site and help us improve it.
- - We use Google Analytics, a web analytics service provided by Google, to perform this task, collecting information including Internet Protocol (IP) address and visited page, as well as any other actions taken while interacting with the website, for example links clicked on. Google Analytics uses cookies to help us analyse how users are interacting with the Website as described later in our Cookie Policy.

If you send us a private or direct message via social media or job sites, the message will be stored relevant to their data retention policies. It will not be shared with any other organisations.

3. Purposes And Legal Basis For The Processing

3.1 We use information held about you for the following purposes:

3.1.1 To carry out our obligations arising from any contracts we intend to enter into or have entered into between you and us and to provide you with the information, products and services that you request from us, or we think will be of interest to you because it is relevant to your career or to your organisation.

3.1.2 To provide you with information about other goods and services we offer that are similar to those that you have already purchased, been provided with or enquired about.

3.1.3 To introduce candidates to our clients for the purpose of temporary or permanent engagement. This is the core service we offer; however, our service expands to supporting individuals throughout their career and to supporting businesses’ resourcing needs and strategies.

3.1.4 To analyse website usage and visitor behaviour patterns.

3.2 Our main legal basis for the processing of personal data is legitimate business interests, described in more detail in the next section, although we will also rely on contract, legal obligation and consent for specific uses of data.

3.2.1 Where we have entered into a contract - We will rely on contract if we are negotiating or have entered into a placement agreement with you or your organisation or any other contract to provide services to you or receive services from you or your organisation.

3.2.2 Where we have a legal obligation - We will rely on legal obligation if we are legally required to hold information on you to fulfil this. An example of this is when we are required to cooperate with the appropriate regulatory and government authorities.

3.2.3 Where we have obtained your consent - We will in some circumstances rely on consent for particular uses of your data. If legally required, you will be asked for your express consent, either orally, by email or by an online process, for the specific activity we require consent for.  Examples of when consent may be the lawful basis for processing include permission to introduce you to a client (if you are a candidate or a partner). You have the right to withdraw your consent to this particular processing at any time by emailing cnd.dpo@CNDLtd.com.

4. Our Legitimate Business Interests

4.1 Where we have not entered into a contract with you, or obtained your consent, or have stated that another legal basis shall apply, then legitimate interest is the legal basis for the following processing activities:

4.1.1 As a recruitment and consultancy business and recruitment agency, we introduce candidates or partners to clients for permanent employment, temporary worker placements or independent professional contracts. The exchange of personal data of our candidates, partners and our client contacts is a fundamental, essential part of this process.

4.1.2 To support our candidates’ career aspirations and our clients’ resourcing and requirement needs, we require a database of candidate and client personal data containing historical information as well as current resourcing requirements.

4.1.3 To maintain, expand and develop our business, we need to record the personal data of prospective candidates, partners, and client contacts as follows:
- - Following an enquiry, we will keep client and candidate information for 3 years, unless contacted by them and directed otherwise.
  - Following an engagement, we will keep client or candidate information for 6 years, unless contacted by them and directed otherwise.
4.1.4 To register office visitors and monitor office security, health and safety.

4.1.5 To assess and improve your experience on our website (such as analysing trends in order to improve your overall experience, or to track your usage of and interactions with the website).

5. Disclosure Of Your Information

5.1 We may be required to disclose or share your personal data in order to comply with any legal obligation, or in order to enforce or apply our terms of use or Master Framework Agreement or Supply of Services Agreement and other agreements; or to protect the rights, property, or safety of Computer Network Defence, our customers, or others.

5.2.1 Clients for the purpose of introducing candidates to them.

5.2.2 Candidates for the purpose of arranging interviews and engagements.

  - We may send a candidate the Hiring Manager’s name and experience so they can effectively prepare for an interview.
5.2.4 Subcontractors including our accountants and other financial service providers.

5.2.5 Analytics and search engine providers that assist us in the improvement and optimisation of our site.

5.2.6 Credit reference agencies, our insurance broker, compliance partners and other subcontractors, such as job sites, for the purpose of assessing your suitability for a role where this is a condition of us entering into a contract with you.

5.3 We do not control your data once it is disclosed to a third party and therefore you should satisfy yourself of their Privacy Policy and how they may collect and distribute information. The lawful basis for the third-party processing may include:

5.3.1 Their own legitimate business interests in processing your personal data, in most cases to fulfil their internal resourcing needs.
