Device Engineer

About Us

At Active Surfaces, our mission is bold: to unlock clean energy in places traditional solar can't reach. Our technology, born from nearly a decade of materials science research at MIT, enables ultra-lightweight, flexible solar modules that install on rooftops, walls, and industrial surfaces once considered off‑limits. With our platform, the built environment itself becomes a source of clean power.

Since our founding, we've rapidly emerged as one of the most exciting startups in climate tech, merging breakthrough science with advanced manufacturing. Backed by leading global investors and strategic partners — including J-POWER, Sabancı, and Lendlease — and having already deployed a paid pilot with a Fortune 500 partner, we're scaling quickly to support a growing pipeline of deployments and commercial opportunities through 2028.

We're expanding our team to support this next phase of rapid growth. These key hires will join a world‑class group with deep expertise in semiconductor and perovskite research, roll‑to‑roll manufacturing, and commercial leadership across the energy sector.

Let's be direct about what this is. We're a small team taking on a genuinely hard problem—and we hire accordingly. This is a high‑intensity, early‑stage environment where the pace is fast and the work you do is load‑bearing: it directly determines whether we scale or we fail. We look for people who hold themselves to an exceptionally high bar, want deep ownership, and are energized rather than daunted by the ambiguity of tough problems.

The work is demanding; the upside—in impact, in career growth, and in equity—is meant to match it. Few people get to materially change whether clean energy reaches places solar never could. If that's the room you want to be in, you'll be surrounded by people who feel the same.

How we work:

• Tackle hard problems first — we front‑load the hardest work to minimize wasted iteration cycles and accelerate learning.
• Stay curious and creative — we thrive in ambiguity and push the boundaries of innovation and are always questioning the status quo.
• Thrive on feedback — we use it to grow quickly, as individuals and as a team - to make ourselves and our products better.
• Act today, not tomorrow — we move with urgency and a bias toward action, after all, climate change isn't slowing down.
• Trust the team and be trustworthy — we communicate openly and show up reliably for one another. We strive to make all our contributions perfect so that our peers and colleagues can do the same.

If you hold yourself to that bar and want to shape the future of solar alongside us, we want to meet you.

As a Device Engineer, you will be a key player in our Engineering Team efforts to advance solar thin‑film devices. Your expertise in thin‑film semiconductor materials, preferably in perovskites and organic photovoltaics (OPVs), will be vital in driving the development of our next‑generation solar products. Reporting to the Founder & Chief Technology Officer (CTO), you will take a leading role in developing, testing and vetting semiconductor materials, to be integrated into our solar device products.

Above all else, we value someone who is a quick, enthusiastic learner, creative problem solver and willing to push the bounds of what would normally be considered ‘standard’. As our company quickly grows its technical capabilities, we are looking for a team member who can grow and scale with us!

This role is eligible for visa sponsorship and relocation. This job will be located full‑time on site in Woburn, MA at our Headquarters and Manufacturing Development site.
