Design the system a household bets its day on. Company Details At M, we’re early, ambitious, and moving fast. We’re building a new category in how urban households function. We help households run smoothly through trained professionals, operational excellence, and technology-driven support systems. Backed by Peak XV Partners, Blume Ventures and CRED, we’re reimagining how homes run, so people never have to think about chores again. Website: https://tellm.co/ The Role Design the system a household bets its day on. M is agentic software in production, and agentic systems are unforgiving: a loop that doesn't converge burns money, a weak boundary corrupts a tenant's data, a slow write makes a household wait. As we scale, you'll take over architecture ownership and set the foundations: the boundaries, the safety, the scale, the standards. Requirements • 7+ years in backend and distributed systems, including real architecture ownership. • You've designed systems that stayed correct and affordable under scale and concurrency. • Deep judgment on data modelling, consistency, isolation, and failure modes. • You've made a fast-growing team better through standards, review, and mentorship. • Calm with ambiguity; you bring order to it. Bonus Qualifications • Worked on agentic/AI systems, event-sourced architectures, or high-stakes transactional systems. • Tamed a runaway cost or reliability problem in a complex system. • Opinions on where automated systems need hard limits and human confirmation. Responsibilities • Own backend architecture as the team and product scale several-fold. • Design the boundaries and safety that keep autonomous, AI-driven systems correct, bounded, and affordable. • Get multi-tenant isolation, reliability, and performance right. • Make the hard design and build-vs-buy calls, and write the standards the team builds against. • Raise the bar through review and mentorship. 30 / 60 / 90-Day Expectations • 30 days: you've absorbed the architecture, found the sharpest risks, and are already shaping decisions. • 60 days: you own architecture for core systems and have led a foundational design the team is building on. • 90 days: you're the architecture owner, standards, boundaries, and the bar are set by you.
