ABOUT BUILD AI Build AI is the data hyperscaler for Physical AI. We're vertically integrated across hardware, manufacturing, logistics, collection, and model training to scale the physical labor dataset orders of magnitude faster than anyone in the world. JOB SUMMARY We build hardware and software to collect data from people doing physical work. We’re hiring a Software Engineer in India to build the systems that run these operations at scale. Our field teams recruit workers, assign wearable cameras, collect devices, upload footage, and coordinate payments. Your software should make this process reliable and easy to run across cities. You will work closely with founders and operations teams to identify problems, ship solutions quickly, and improve them based on field use — owning each problem from understanding through deployment and support. You should be comfortable working across the stack and learning whatever is needed. KEY RESPONSIBILITIES - Build web and mobile tools for field teams, partners, and internal operations - Build workflows for worker onboarding, device assignment, attendance, collection tracking, and payments - Build dashboards that make collection volume, data quality, costs, and operational problems visible - Integrate applications with upload, storage, and data quality systems - Make field workflows reliable when connectivity is poor or uploads fail - Automate manual processes that slow down operations or introduce errors - Work directly with operators to understand problems and test solutions in the field - Own features from design and implementation through testing, deployment, and monitoring - Investigate production failures and fix the underlying causes - Make practical trade-offs between speed, reliability, and maintainability YOU MAY BE A GOOD FIT IF YOU HAVE (MUST-HAVE QUALIFICATIONS) - Have personally built and shipped software used by real users - Can work across frontend, backend, APIs, and databases - Can turn an unclear operating problem into a working product - Can debug issues across application code, infrastructure, and third-party integrations - Understand testing, access control, and reliable data handling - Can work independently and communicate clearly with technical and nontechnical teams STRONG CANDIDATES MAY ALSO HAVE EXPERIENCE WITH (NICE-TO-HAVE QUALIFICATIONS) - Building Android applications - Python, TypeScript, React, and PostgreSQL - Building software for field operations, logistics, or workforce management - Large file uploads, video processing, or data pipelines - Building applications that work with unreliable connectivity - Working at an early-stage company WHAT WE LOOK FOR - Deep desire to solve extremely challenging problems - High learning rate - High agency - Intense determination - Attention to detail - Low ego - Creative, not constrained by how things have been done before Immediate rejects: inability to change, limiting beliefs, low ambition. BENEFITS - Competitive pay - Medical, dental, and vision packages with generous premium coverage - $500 per month credit for waiving medical benefits - Housing subsidy of $2k per month for those living within walking distance of the office - Relocation support for those moving to San Francisco (Financial District) or Shenzhen (Nanshan) - Various wellness benefits covering fitness, mental health, and more - Daily lunch and dinner in our office - Unlimited compute budget subject to ROI justification - Unlimited Codex and Claude credits - Travel HOW WE'RE DIFFERENT Build believes in the Bitter Lesson http://www.incompleteideas.net/IncIdeas/BitterLesson.html. By taking a general approach of learning from humans, our addressable market is all physical labor. We are a fully in-person team in San Francisco (Financial District) and Shenzhen (Nanshan), and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both and work across disciplines as needed. Build AI is an equal opportunity employer. We review every application. If you do not meet every bullet, still apply. Questions: research@build.ai
