Dear Hiring Manager,

In searching for a company that prioritizes cutting-edge technology and impactful solutions, I discovered your team's dedication to leveraging software innovations in healthcare. Your commitment resonates deeply with my professional philosophy and my systematic approach to backend engineering.

One of the most significant achievements of my career occurred at Epic Systems Corporation, where I led a team to revamp the backend data querying system. We successfully executed enhancements that resulted not only in a 40% improvement in data retrieval speeds, but also in a substantial reduction of load on our systems—paving the way for more robust and responsive healthcare applications. This exercise honed my expertise in NoSQL databases and AWS services, and it underscored my commitment to delivering substantial, measurable results.

I am eager to bring my decade-long experience as a Senior Backend Software Engineer and a record of impactful technology implementations to your esteemed team. I am confident that my background in developing advanced backend systems can contribute to the innovative work you're doing and help drive your mission forward.

I look forward to the opportunity to discuss how my skills and accomplishments align with the goals of your team, and I am keen to explore how we can collaborate to generate outstanding results in the future. Thank you for considering my application.

Sincerely,

Carla Jensen

Key qualities recruiters search for in a candidate’s cover letter

  • Proficiency in secure coding practices: Recruiters look for candidates who understand the principles of writing secure code and can implement security measures to protect applications from vulnerabilities like SQL injection, XSS, and CSRF.

  • Familiarity with security frameworks and standards: Knowledge of frameworks such as OWASP Top 10 and familiarity with compliance standards like GDPR, HIPAA, or PCI DSS is essential for establishing and maintaining the security of applications.

  • Experience with security testing and tools: Hands-on experience with tools such as static and dynamic analysis tools (SAST/DAST), penetration testing tools, and vulnerability scanners helps in identifying and mitigating potential security risks.

  • Incident response and threat modeling: The ability to create threat models and respond to security incidents is critical for proactive defense and quick recovery from attacks.

  • Understanding of authentication and authorization systems: A strong grasp of identity and access management, including knowledge of OAuth, OpenID Connect, SAML, and multi-factor authentication, is key for securing user data and access points.

  • Strong communication and collaboration skills: Application security engineers must effectively work with cross-functional teams and need to clearly communicate security risks and defensive strategies to non-technical stakeholders, including providing training and awareness programs.

Personalizing your application security engineer cover letter salutation

Always aim to address the recruiter from the get-go of your application security engineer cover letter.

Use:

  • the friendly tone (e.g. "Dear Paul" or "Dear Caroline") - if you've previously chatted up with them on social media and are on a first-name basis;
  • the formal tone (e.g. "Dear Ms. Gibbs" or "Dear Ms. Swift") - if you haven't had any previous conversation with them and have discovered the name of the recruiter on LinkedIn or the company website;
  • the polite tone (e.g. "Dear Hiring Manager" or "Dear HR Team") - at all costs aim to avoid the "To whom it may concern" or "Dear Sir/Madam", as both greetings are very old-school and vague.

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Company Name] Team,
  • Dear [Department] Department,
  • Dear [Mr./Ms./Dr.] [Last Name],
  • Esteemed Selection Committee,
  • Respected Recruiter,

Your application security engineer cover letter intro: showing your interest in the role

On to the actual content of your application security engineer cover letter and the introductory paragraph.

The intro should be no more than two sentences long and presents you in the best light possible.

Use your application security engineer cover letter introduction to prove exactly what interests you in the role or organization. Is it the:

  • Company culture;
  • Growth opportunities;
  • Projects and awards the team worked on/won in the past year;
  • Specific technologies the department uses.

When writing your application security engineer cover letter intro, be precise and sound enthusiastic about the role.

Your introduction should hint to recruiters that you're excited about the opportunity and that you possess an array of soft skills, e.g. motivation, determination, work ethic, etc.

Intro Paragraph
With a solid background in fortifying applications against the ever-evolving landscape of cyber threats, I am keen to contribute to [Company Name]'s renowned commitment to cutting-edge security solutions and robust protective measures.
RIGHT

What comes next: your application security engineer cover letter middle paragraphs

In the next three to six paragraphs (or the body of your application security engineer cover letter) you have to prove your unique value.

Most candidates tend to mess up at this stage. They tend to just copy-paste information from their resume.

That's one big no-no.

Remember that when writing your application security engineer cover letter, it has to be personalized. And, your ultimate aim is to catch the recruiter's eye.

So, look back on key job requirements and write down a list that includes the ones you cover.

Next, select just one key achievement from your professional (or personal) history that meets those advert keywords.

Narrate a story around how you've grown your skill set and knowledge. Also, aim to show the unique understanding or soft skills you bring about, thanks to your past success.

Body Paragraph
At my previous role, I spearheaded the integration of a robust intrusion detection system that reduced security breaches by 45% in the first quarter post-implementation. Through meticulous code reviews and enhancements to our API security protocols, I also achieved a 20% improvement in our application's resistance to XSS and SQL injection attacks, significantly bolstering our app's defense against common vulnerabilities.
RIGHT

Final words: writing your application security engineer cover letter closing paragraph

The final paragraph of your application security engineer cover letter allows you that one final chance to make a great first impression.

Instead of going straight to the "sincerely yours" ending, you can back up your skills with a promise of:

  • how you see yourself growing into the role;
  • the unique skills you'd bring to the organization.

Whatever you choose, always be specific (and remember to uphold your promise, once you land the role).

If this option doesn't seem that appealing to you, close off your application security engineer cover letter with a follow-up request.

You could even provide your availability for interviews so that the recruiters would be able to easily arrange your first meeting.

Closing Paragraph
Eager to discuss how my skills align with the goals of your security team, I look forward to the opportunity for an interview.
RIGHT

Keep this in mind when writing your zero experience application security engineer cover letter

Even though you may not have any professional experience, your application security engineer cover letter should focus on your value.

As a candidate for the particular role, what sort of skills do you bring about? Perhaps you're an apt leader and communicator, or have the ability to analyze situations from different perspectives.

Select one key achievement from your life, outside work, and narrate a story that sells your abilities in the best light.

If you really can't think of any relevant success, you could also paint the picture of how you see your professional future developing in the next five years, as part of the company.

Key takeaways

Winning recruiters over shouldn't be difficult if you use your application security engineer cover letter to tell a story that:

  • Is personalized by greeting your readers and focusing on key job skills greets;
  • Isn't spread all over the place, but instead focuses on one key achievement and selling your value as a professional;
  • Introduces your enthusiasm for the role, passion for the job, or creativity in communication;
  • Is also visually appealing - meeting the best HR practices;
  • Ends with a nod to the future and how you envision your growth, as part of the company.
