What the job involves
- BillionToOne is looking for a People Operations Manager to join our growing People team and play a critical role in scaling our people programs, systems, and operations
- This role will own and enhance core People Ops programs while serving as a key partner in driving operational excellence, vendor strategy, and data-informed decision-making
- This is a hybrid role (2–3 days onsite per week at our Menlo Park and/or Union City office) reporting to the Associate Director of People Operations
- Design, optimize, and scale core People Ops programs (onboarding, offboarding, performance cycles, engagement/recognition, and compliance), driving strategy, scalability, and continuous improvement
- Own and scale benefits strategy and operations, serving as the primary lead for vendor partnerships (benefits brokers, payroll providers, etc.)
- Act as the program manager for performance cycles, driving end-to-end execution, stakeholder alignment, and continuous improvement
- Design and implement scalable processes and systems, proactively identifying gaps and driving operational efficiency
- Partner with the Associate Director to operationalize strategic initiatives (e.g., recognition program, engagement survey, etc.)
- Maintain strong policy and compliance knowledge, recommending updates to enhance both compliance and employee experience
- Serve as the Tier 2 escalation point for complex employee inquiries, resolving issues independently and escalating only critical matters as needed
Our take
BillionToOne is a precision diagnostics company. Its proprietary molecular counting platform (Quantitative Counting Templates) accurately counts DNA molecules at the single-count level, which has the ability to significantly improve disease detection. While initially focused on prenatal screening and oncological liquid biopsies, the company’s QTC technology is highly scalable and has the ability to make vast improvements to a range of disease detection verticals.
The company’s funding efforts - most notably a 2025 IPO - will enable it to focus on further development and commercialisation of its noninvasive prenatal screening test and oncology products. However, it will need to maintain a strategic outlook, prioritising areas with higher testing frequencies to maximise patient benefit and balance test development costs.
BillionToOne has an important role to play in improving healthcare equity. As more promising peer-reviewed research studies are conducted and providers have increased confidence in the company’s tests, BillionToOne has significant growth potential.
