Where rare disease meets uncommon opportunity
At Mirum, Relentlessly Rare means caring deeply—and acting decisively. We build with intention, lead with integrity, and execute with focus for patients and families who inspire our work.
We are a team of scientists, strategists, operators, and advocates who believe high performance and purpose go hand in hand—and together drive meaningful progress.
Our Mirum core values
High performance and having fun are not opposites—they fuel each other and drive meaningful results for our patients. That’s why we live these four core values every day.
Care.
We care deeply because the work matters to patients and families counting on progress. And for each other, we bring that care to life through empathy, appreciation, and open, honest communication.
Be real.
Bring your authentic, honest, and open self to work while valuing diverse perspectives and collaboration.
Have fun, seriously.
Foster energy, connection, and joy at work by celebrating together and keeping things lighthearted.
Get it done!
Take initiative, act with integrity, and work collaboratively to deliver results and shared goals.
Where patients come first—always
Our work begins and ends with patients. We partner closely with advocacy communities, listen deeply to lived experience, and let those insights guide how we design trials, pursue approvals, and prepare for access.
For our teams, that means clarity of purpose. It means knowing that every dataset, every meeting, and every decision connects back to someone waiting for progress. That’s what keeps us focused and our work meaningful.
“The thing that makes Mirum different is our leadership. They set the tone for how everyone treats each other. They’re real and authentic, but they also have great expectations. Without that, I don’t think you could have what you have here.”
“One of the things that excites me most at Mirum is getting to know the people who join the organization—and being able to show them that values aren’t just words. They can be lived. You can develop as an individual while building a company.”
“The office is really unique—the names of the conference rooms are actual patient names. The artwork we’ve done for them illustrates how we see them—as superheroes. It motivates me to want to work harder.”
“Mirum’s patient-centric approach doesn’t just inspire me—it drastically changes the way I do my job.”

Where we work
We believe in the energy that happens when teams come together—and we respect the flexibility modern life requires. Arrangements vary by role, so ask us what’s possible.
Foster City is the global headquarters of Mirum and home to many of our corporate, development, and cross-functional teams. Nestled in the heart of the Bay Area, our HQ sits among a vibrant life sciences community—reflecting the spirit of innovation that drives our work in rare disease.
Connection is part of our rhythm here. Team members gather over catered lunches Tuesday through Thursday and connect with colleagues over Monday coffee chats (with an on-site barista). Snacks, beverages, and EV charging stations make the everyday experience easy and energizing—so people can focus on what matters most.
Our Basel office is the European heart of Clinical Development and Operations. Here, teams advance our pipeline with rigor and urgency, working closely across functions to bring meaningful therapies to patients living with rare diseases.
Beyond the science, connection matters. Weekly off-site “Coffee and Chats” create space for thoughtful conversation, and bi-weekly “Lunch Connections”—hosted in the office or at local restaurants—strengthen collaboration across teams. With snacks and beverages available on-site, Basel offers an environment designed for both focused work and genuine camaraderie.
Zug is home to our European Commercial and Medical Affairs teams—bringing together deep biopharmaceutical expertise from development through commercialization. With strong insight into rare disease communities across Europe and surrounding regions, this team plays a critical role in ensuring our medicines reach the patients who need them.
Regular “Coffee and Chats” and bi-weekly “Lunch Connections” foster open dialogue and cross-functional partnership, reinforcing a culture where collaboration drives impact. A welcoming office environment with stocked snacks and beverages supports both productivity and connection.
