About Hemab

Hemab is building preventative treatments for serious, underserved bleeding disorders.

We went public via our 2026 IPO, and were scaling across two homes: Cambridge, MA, USA, and Copenhagen, Denmark.

What to expect, honestly

Hemab is still building a lot of its own structure. Systems here tend to get created as we need them, not handed down in advance. Whoever takes this role will likely build some of their own process instead of inheriting a finished one. We work across two hubs and multiple time zones - bridging that well takes real, deliberate effort. And because were growing quickly, priorities can shift with less notice than they would at a larger, more established company.

This is the actual shape of working somewhere at this stage: Its genuinely energising for the right person and genuinely frustrating for the wrong one. If you want a place where the operating manual is already written, this might not be it - but if you want to help write it, this might be exactly it.

Why Hemab

At Hemab, your work ultimately connects back to something simple. People living with serious bleeding disorders get something theyve never had before - the chance to prevent a bleed, instead of reacting to one after it happens. Youll be joining at a stage where individual decisions still carry real weight, and where your work can help turn promising science into a preventative treatment that actually reaches patients.

How we treat our people is meant to be an extension of how we think about patients: with care, honesty, and respect. Were still building the consistency to back that up across every hiring process, every time. Wed say that plainly instead of pretending otherwise. If any part of your experience with us falls short of it, tell us.

Hemab builds balanced candidate slates and assesses everyone against a single standard. If you need a reasonable adjustment at any stage of the hiring process, please tell us.
