HR Manager at Atlas Biotech

Human Resources
Senior

Dear Ms. Tran,

I am writing to apply for the HR Manager position at Atlas Biotech. With seven years of progressive HR experience spanning talent acquisition, employee relations, and organizational development, I am prepared to lead the people strategy for a company at your stage of growth.

In my current role at Vanguard Health Sciences, I manage a team of three HR generalists supporting a workforce of 420 employees across four locations. Over the past two years, I redesigned our recruitment process end-to-end, reducing average time-to-fill from 52 days to 31 days while improving quality-of-hire scores by 23% as measured by 90-day manager satisfaction surveys. I also led the rollout of a structured onboarding program that increased new hire retention at the 12-month mark from 71% to 89%.

Beyond recruiting, I partnered with our executive team to develop a competency-based performance management framework that replaced our outdated annual review system. The new quarterly check-in model achieved 92% manager adoption in its first cycle and was directly cited by 64% of employees in our engagement survey as a positive change. Our overall engagement score rose from 3.6 to 4.1 out of 5 within one year of implementation.

What draws me to Atlas Biotech is the challenge of scaling a people function alongside rapid headcount growth. I have experience building HR infrastructure from the ground up, including implementing our HRIS, writing our first employee handbook, and establishing compliance protocols for multi-state operations. I understand what it takes to professionalize HR without losing the culture that made the company attractive in the first place.

I would welcome the chance to discuss how my experience can support Atlas Biotech's growth while preserving the culture your team has built. Thank you for your consideration.

Best regards,
Elena Petrova, SHRM-CP

Why this HR manager cover letter works

Opens with breadth and depth. Elena names three HR disciplines and frames her experience as progressive, signaling she has grown into increasingly complex responsibilities rather than staying in a single lane.

Treats HR metrics like business metrics. Time-to-fill, quality-of-hire scores, and retention rates are presented with the same rigor a finance person would bring to a P&L review. This positions Elena as a strategic partner, not just an administrator.

Shows culture-building with evidence. The performance management overhaul is described in terms of adoption rate and employee sentiment data, proving that the initiative was not just launched but actually worked. The engagement score lift gives it a clear before-and-after.

Addresses the company's stage directly. The closing paragraph acknowledges Atlas Biotech's growth challenge and describes Elena's experience building HR systems from scratch. This is exactly what a scaling company needs to hear.
