[Hiring] Patient Growth Manager @Massive Bio

Role Description

Massive Bio is growing fast; more patients, more sponsors, more trials, more countries. We're creating a Patient Growth Manager role to lead the engine that finds cancer patients and brings them into the clinical trials that can help them.

What makes this role distinctive is where the work begins:

• Find the patient.
• Determine which open studies they are genuinely eligible for.
• Support them through to the institution that can treat them.

This person owns the patient growth and enrollment funnel end to end:

• Identification
• Outreach
• Qualification
• Site referral
• Screening
• Consent
• Randomization

You will work across internal teams (clinical operations, technology, provider engagement) and external stakeholders (sites, sponsors, CROs, site networks) to drive throughput, remove friction, and ensure our growth doesn't outpace our ability to deliver.

This is an operations leadership role. You will own enrollment outcomes and the processes behind them. As volume scales, you'll build and manage a team of Project Managers to expand delivery capacity.

Qualifications

• Direct, hands-on experience finding and enrolling patients into clinical trials.
• Oncology experience; comfortable with cancer indications, biomarkers, and eligibility criteria.
• Working knowledge of how a clinical trial runs; protocols, eligibility criteria, screening and consent, site workflow.
• Track record of driving enrollment numbers; can point to volume, conversion rate, or throughput improvements.
• 5+ years leading operational delivery in a complex, multi-stakeholder environment.
• Experience owning a conversion funnel or delivery pipeline end to end.
• Track record of scaling an operational function in a fast-growing organization.
• Experience coordinating across multiple external partners and internal teams.
• Strong analytical skills; proficient in building dashboards and working in Excel.
• Structured project management discipline; ability to run multiple parallel workstreams.
• High energy and comfort with ambiguity; startup environment.

Requirements

• Experience at a patient recruitment company, clinical trial matching platform, or integrated research organization.
• Direct-to-patient marketing or paid patient acquisition experience.
• Experience building referral relationships with community oncologists or academic centers.
• Background in operational value creation, management consulting, or private equity portfolio operations.
• Experience with AI-powered platforms or health technology.
• PMP or equivalent project management certification.

Benefits

You will be building the growth engine for a company in a high-growth phase where enrollment speed is the product. Every trial you move forward represents a group of cancer patients who reach a treatment option they would not otherwise have found.

The role is designed to grow, with a direct line to the C-level and co-founders, and within 12 to 18 months you will hire and lead your own team.

The pace here is fast and the scope is wide. If you are someone who would rather own an outcome and be trusted to go and get it than work inside a narrowly defined lane, you will find a great deal of room to do that here.
