System Performance Engineer Jobs

About the Team ValMo is Meesho's logistics and supply chain organization, responsible for building India's most cost-efficient, reliable, and scalable fulfillment network. From first-mile pickup to last-mile delivery and reverse logistics, ValMo powers millions of shipments every month for small businesses across the country. As we scale, the complexity of our network increases exponentially. ValMo operates at the intersection of technology, operations, and partner ecosystems — where execution precision and systems thinking are critical to prevent cascading (domino) failures across the network. About the Role The Control Tower is where the stability, reliability, and cost-efficiency of ValMo's pan-India network is owned end-to-end. This is a deliberately generalist role in Fulfilment & Experience - your mandate is defined by an outcome, not a fixed function. Put simply: you are the person we point at the highest-leverage problem threatening the network, and you figure it out from first principles. The specific problem changes with what the network needs. In one quarter you might be redesigning the topology of a region; in the next, rebuilding the capacity-planning engine, running a structural cost-out program, firefighting an RTO or CX spike, or standing up readiness for a peak event - including problems that don't yet have an owner. What stays constant is the accountability: keep the network stable, predictable, and cost-efficient no matter what breaks or scales. What you will do 1. Own network stability (the constant) This is the through-line of the role regardless of what else you pick up: Set up and govern the automated dashboards, early-warning frameworks, and control-tower rituals tracking end-to-end SLAs, TAT, RTO, and cost health across first-mile, middle-mile, and last-mile. Detect real-time and structural exceptions across the linehaul and sorting ecosystem, and trigger rapid-response protocols <em
