Senior Backend Engineer (Python/TypeScript)

About the role

TellM is building software that helps urban households run smoothly through trained professionals, operational excellence and technology-driven support systems. It is hiring a Senior Backend Engineer in Bengaluru to own the backend architecture, safety boundaries and engineering standards for its agentic systems. The position is on-site in Bengaluru.

Key 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.

Required profile

• 7+ years in backend and distributed systems, including real architecture ownership.
• Experience designing systems that stayed correct and affordable under scale and concurrency.
• Deep judgment on data modelling, consistency, isolation and failure modes.
• Experience improving a fast-growing team through standards, review and mentorship.
• Calmness with ambiguity.

Bonus qualifications

• Work on agentic/AI systems, event-sourced architectures or high-stakes transactional systems.
• Having tamed a runaway cost or reliability problem in a complex system.
• Opinions on where automated systems need hard limits and human confirmation.

The expected timeline is: 30 days to absorb the architecture and shape decisions, 60 days to own architecture for core systems, and 90 days to set the standards and boundaries.
