Importance of cover letters in the United Kingdom

Cover letters are a vital part of professional job applications, helping shape recruiters' first impression of your profile.

Here’s why they’re important:

  • Indicates your genuine interest: A well-researched cover letter reflects your knowledge of the company and role.
  • Professionalism from the outset: Employers expect your cover letter to be structured, polite, and formal. If you wish to add a more personalised touch, be sure to address your recipient directly.
  • Capture the recruiters' attention: For most roles, candidates tend to have rather similar experience, which is why you should use your cover letter to explain what is unique about your profile.

What UK employers expect from a cover letter

When writing your cover letter for a UK employer, it’s important to keep several things in mind. First, you need to conduct a thorough research, which includes reading up on the company’s website, recent news, and their presence on social media. Understanding the company’s latest achievements and its overall mission will allow you to tailor your letter to their specific needs.

Next, focus on the company’s core values. Whether they value teamwork, innovation, or community involvement, highlighting how your own experience aligns with these principles is essential.

Finally, don’t forget to match your skills to the job’s requirements. Study the job description carefully and pick out the most important qualifications or competencies. Then, provide evidence of how you meet those criteria with concrete examples from your past work experience.

How to format a embedded software engineer cover letter

Before diving into the content, the structure of your cover letter should include the following elements:

  • Your address and contact details
  • The employer’s name and address
  • Date
  • Salutation or greeting
  • Opening or introductory paragraph
  • Middle or body paragraphs
  • Closing paragraph
  • Sign-off and signature

When it comes to the best font choice, consider modern options like Lato, Rubik, Raleway, Volkhov, Chivo, or Bitter as alternatives to Arial or Times New Roman.

Your cover letter should be single-spaced, with approximately 1-inch (2.5 cm) margins all around (our templates are set up automatically with this spacing in mind).

Ensure your CV and cover letter use the same font for consistency, and always send them as a PDF to prevent edits and maintian formatting.

Lastly, while Applicant Tracking Systems (ATS—the software used to match your application to set requirements) won't read your cover letter, recruiters certainly will, so make sure it stands out.

How to write your embedded software engineer cover letter salutation

In a world of AI and instant prompts, taking the extra time to personalise your cover letter truly makes a difference.

Address the hiring manager directly with a customised greeting (e.g., 'Dear Mr Bond', 'Dear Ms Penny').

You can often find their name on LinkedIn (under the job listing or by searching) or in the ‘About’ or ‘Meet the Team’ section of the company's website. If in doubt, you can also contact the reception for assistance.

If you can't find the name, rather than using 'Dear Sir or Madam', opt for something more personal, such as 'Dear [Company Name] Hiring Manager'.

How to write your embedded software engineer cover letter intro

It's never a bad time to show enthusiasm about the role, company, or team in your cover letter introduction.

Begin by sharing one or two aspects that genuinely excite you about the position—whether it's the company culture, specific responsibilities, or the team's past achievements.

Your enthusiasm demonstrates that you'll bring a strong work ethic, are eager to contribute, and are motivated to succeed.
