💡 ABOUT ARCH
Arch powers frontline industries with cutting-edge AI.
The US $800 billion frontline-services sector underpins the nation, yet many of these critical businesses still rely on spreadsheets, outdated software, and paper forms. We’re driving energy resilience, economic strength, and long-term prosperity by bringing cutting-edge AI to the frontline services that need it most.
We’re backed by Coatue, Floodgate, Gigascale, ReGen, MCJ Collective, and the founders of Aurora Solar.
Competitive salary + significant equity package based on experience.
🎒 Role Overview:
We're hiring a Software Engineer to join our tight-knit engineering team of four. In this high-impact and fast-paced role, you'll collaborate directly with our founders to build products at the cutting edge of technology and sustainability. This role requires in-person collaboration 3-4 days per week at our San Francisco office (WeWork or office on Union Square).
If you’re motivated by solving challenging problems, have a passion for elegant code, and want your work to have a meaningful impact, we'd love to hear from you.
🏃 What You'll Do:
- Build and enhance core product features, from backend logic to intuitive user interfaces.
- Own your work end-to-end, from concept through deployment.

- Technical Stack: Proficiency in TypeScript (our stack includes Node.js, Next.js, PostgreSQL).
- Engineering Excellence: A passion for crafting clean, elegant solutions to complex problems.
- ML experience: Exposure to classic ML workflows (even through side projects): data cleaning, model training, and iteration.
Strong Bonuses:
- Experience handling large-scale datasets—we deal with billions of records and focus heavily on query performance.
- Familiarity with leading-edge AI productivity tools (Cursor, Windsurf, MCP, etc.).
🧑🤝🧑 Who You'll Work With:
Philipp (Co-Founder & CEO) - Hi, I’m Phil! 👋 Raised on a small strawberry farm in Bavaria, Germany, I'm passionate about sports, hiking, and exploring meditation and biohacking. Before founding Arch, I earned an MBA and Master’s in Environmental Science from Stanford, led global solar projects with 180+ employees, and was a management consultant at McKinsey, helping software companies scale. Ask me about my favorite cafes and brunch spots in SF!
Sacha (Co-Founder & CTO) - Hi, I'm Sacha! Originally from Belgium, I discovered my passion for climate tech after experiencing devastating fire seasons in Australia and California. With a dual M.Sc. in Engineering and Management, I thrive at the intersection of engineering, design, and strategy. My entrepreneurial journey includes both early failures (a Tinder-like app ahead of its time) and successes (a YC-backed company with 40+ employees). Previously, I built AI tools enabling first responders to rapidly identify fire ignition zones, directly influencing my path to founding Arch.
Interviews start the week of March 31st.
