About us

Interstitial formed organically as a collective of technology freelancers looking to combine our skills and work together on projects we believe in. We come from diverse backgrounds - embedded systems, web development, data science and more - but we share in this common goal: to make the world a better place through technology. We work on environmental science, sustainable agriculture, the green economy, and human rights. We are engineers, scientists, designers and architects onboard Spaceship Earth.

Our innovative contracting model allows for substantial flexibility in matching our workforce with the needs of our clients. From hourly consulting to long-term contracts and government grants, Interstitial delivers high-quality engineering solutions for a variety of project structures.

We believe that good ideas deserve to be shared, so we are committed to practicing open-source principles wherever possible. Our developers maintain and contribute to open software and hardware projects that are used around the globe. Check out our GitHub.

We operate democratically as an employee-owned worker cooperative. Our flat and fair structure encourages collaboration at every level, and ensures that everyone is invested in the quality of our work. It also makes Interstitial a great team to be a part of - if you’re a technology professional interested in working toward positive change, please reach out to us!

Beth (she/her) is a health tech design researcher and epidemiologist with 10+ years experience optimizing domestic and global health technologies. Beth gets exceptionally excited about designing point-of-care technologies to support frontline healthcare providers (e.g Electronic Health Records or Community Health Worker apps). As a PhD student in human centered design and engineering, current projects include: reimagining patient consent for routine care in low resource settings; redesigning a project management toolkit for global health informatics projects; gathering requirements for an app to support people living with HIV in Jamaica; and exploring new ways to cost and evaluate digital health systems. She loves facilitating workshops, creating plans to evaluate tech, conducting user research, employing quantitative and implementation science research methods, working with the public sector, and supporting complex requirements gathering projects.

Evan (he/him) is a versatile engineer with experience ranging from real-time C++ signal processing to full-stack web development. He has years of experience developing industry standard professional and creative audio applications working on everything from performance critical DSP algorithm design, to multi-threaded reactive user interfaces. He is motivated by projects that bring equity, sustainability, and joy to human systems.

Sophie is an Electrical + Embedded Hardware Engineer with nearly a decade of experience in circuit design and PCB layout, hardware testing, software and firmware (C, Python, Arduino C++), and technical documentation. She has designed and tested hardware and software systems for battery management, automated PCBA testing, electrical fault management, and more. She is enthusiastic about sharing of knowledge, both as a learner and mentor.

Rebecca is a design-researcher with 8+ years of experience across private and public sectors. Her diversity of projects range from producing games for civic engagement, working on a biotech design team, to managing hackathons for maternal health. Her current graduate studies focus on human-centered design and engineering. Skills include: user research, qualitative methods, project management, and community development.

Josh likes to learn about the way things work and how they came to be. He's contributed to numerous projects around the globe - ranging from the eradication of Polio in Nigeria to a flying electric vehicle startup in silicon valley. He loves multidisciplinary projects, especially projects that are focused on sustainability and integrate permaculture/regenerative design into their scope. He dreams of a zero-waste manufacturing ecosystem and seeks to support local and global communities in their efforts to build one.
