ALIVE In Purpose

Changing healthcare for the better.

Arranta Bio is a fast-growing contract development and manufacturing organization (CDMO) with deep roots in the biopharmaceutical industry. A startup at our core, Arranta Bio was conceived by our team of experienced, entrepreneurially driven leaders with the goal of revolutionizing disease etiology through therapies focused on the human microbiome. The name Arranta originated from the Gaelic word meaning “bold and daring”, and working at Arranta Bio means having a direct hand in supporting the pioneers who are innovating human microbiome therapies and giving hope to patients in need.

ALIVE In Passion

Pushing the boundaries of what’s possible. Making a difference in people’s lives.

At Arranta Bio, we’re not just doing a job – we’re answering the call for innovative therapies to treat unmet needs. We are collectively impassioned by the work we do and the people we impact, which is why we continuously challenge ourselves to grow, learn and surpass the limits of our capabilities. If you are a problem-solver, innovator and collaborator who thrives in an agile, rapidly moving environment, then it sounds like you may be ready to answer the call with us.


Celebrating diversity, inclusion and allyship.

We couldn’t advance our mission of becoming the best-in-class microbiome CDMO without the diverse breadth of people, identities, cultures and perspectives across our organization. That is why we hold ourselves to an exceptionally high standard of diversity and inclusion and provide equal opportunity employment across socioeconomic boundaries.

As part of our commitment to empowering individuals of all backgrounds and circumstances to realize their potential, we partner with Year Up, a nonprofit organization working to close the opportunity divide for young people outside of the economic mainstream. We are currently hosting two Year Up interns at our Watertown, Massachusetts, facility and look forward to welcoming more future innovators on an ongoing basis.

Learn More About Diversity at Arranta Bio

We can be paralyzed by the challenges and divisions in our society. We can feel overwhelmed until we recognize that there are many actions we can take to make a difference. It’s our duty to open doors, support those of color and from diverse backgrounds to pursue a fulfilling career in life sciences. Let’s take those steps together.

ALIVE Together

Listening, learning, leading.

What defines a great company culture is more than just fantastic team-building events and a never-ending supply of coffee and snacks (though don’t get us wrong – we’ve got all that and more). The way we see it, celebrating our successes, recognizing the contributions of our teams and lifting one another up in times of need are pillars of a great place to work.

We lead with openness and transparency, looking to our employees for ways to improve as a company. In fact, we have a dedicated employer of choice project team continuously seeking input from staff on what they look for in an employer – feedback we take to heart and incorporate into our organizational strategy.

A Word on COVID-19

You’ve likely seen companies touting the phrase, “business as usual,” amid the COVID-19 pandemic. Although we remain unfaltering in our ability to deliver for our customers, we recognize that the current circumstances are anything but usual. The wellbeing of our employees and their families is our top priority, and we are taking all necessary precautions to ensure their health and safety. We acknowledge and appreciate the contributions of our staff during this difficult time, starting each day with a (virtual) huddle of gratitude and encouragement.
