Staff Software Engineer | Backend, Python and FastAPI

A staff backend role at Harvey, the AI for legal work company, in Bengaluru. The stack is named precisely, which is helpful at this level: Python with a modern web framework such as FastAPI or Flask, relational databases with Postgres named, and cloud on Azure, AWS or GCP. The requirements go beyond code into operating reality, asking for comfort running services in production using logs, metrics, dashboards and alerts, including participation in an on call rotation, which is stated rather than implied. Stated bar is twelve or more years of backend engineering building and operating production web applications or SaaS products. Good fit for a senior backend engineer who wants an AI product where the domain, professional legal work, demands correctness over novelty.

Published requirements: 12+ years of backend engineering experience building and operating production web applications or SaaS products; a track record of building fast growing SaaS products using progressive web application technologies; a track record of shipping highly intuitive products with strong attention to detail; strong programming skills in Python with experience of a modern web framework such as FastAPI or Flask; hands on experience with relational databases, with Postgres named; a solid understanding of API design, authentication and authorisation, background job patterns and robust error handling; experience building for cloud infrastructure on Azure, AWS or GCP; and comfort operating services in production using logs, metrics, dashboards and alerts, including participation in an on call rotation. The on call expectation is stated explicitly in the requirements rather than buried, which is honest and worth knowing before you apply. Location is Bengaluru. Domain context: Harvey builds AI tools for legal and professional services work, so the backend serves a product where users are lawyers acting on the output. That raises the bar on correctness, traceability and data handling compared with a general consumer product, and background job patterns appearing in the requirements is a hint about the workload shape, since document processing and model inference are long running rather than request response. Company culture as published: three stated values, decisiveness, simplicity and Job's Not Finished, with candid language about moving fast, operating with intensity and staying close to customers. Two of Harvey's three engineering roles today ask for 12+ years and the third asks for 10+, so this is a consistently senior team rather than a mixed one. Good fit for a backend engineer with twelve or more years who wants Python depth on an AI product and accepts a genuine on call rotation as part of the role.
