We’re driving energy resilience, economic strength, and long-term prosperity by bringing cutting-edge AI to the frontline services that need it most.\nWe’re backed by Coatue, Floodgate, Gigascale, ReGen, MCJ Collective, and the founders of Aurora Solar.\nCompetitive salary + significant equity package based on experience.\nRole Overview:\nWe'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).\nIf 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.\nWhat You'll Do:\nBuild and enhance core product features, from backend logic to intuitive user interfaces.\n\nOwn your work end-to-end, from concept through deployment.\n\nCollaborate closely with our founders and engineering team to define and execute our technical roadmap.\n\nExperiment and innovate with new technologies, particularly in AI/ML, to enhance our offerings.\n\nQualifications:\nMust-haves:\nStartup Experience: 5+ years software engineering experience in a fast-paced startup environment.\n\nTechnical Stack: Proficiency in TypeScript (our stack includes Node.js, Next.js, PostgreSQL).\n\nEngineering Excellence: A passion for crafting clean, elegant solutions to complex problems.\n\nML experience: Exposure to classic ML workflows (even through side projects): data cleaning, model training, and iteration.\n\nStrong Bonuses:\nExperience handling large-scale datasets-we deal with billions of records and focus heavily on query performance.\n\nFamiliarity with leading-edge AI productivity tools (Cursor, Windsurf, MCP, etc.).\n\nWho You'll Work With:\nPhilipp (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!\nSacha (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.\nInterviews start the week of March 31st.\nReady to Make an Impact?\nIf this sounds like you, we'd love to connect.
