Lead Modeling And Simulation Engineer Jobs

About the Team The security team at Meesho is like the Avengers to Meesho's S.H.I.E.L.D. After all, when 5% of Indian households shop with us, it’s important to build resilient systems to manage millions of orders every day. We’ve done this – with zero downtime! 😎 Sounds impossible? Well, that’s the kind of Engineering muscle that has helped Meesho become the e-commerce giant it is today. We value speed over perfection, and see failures as opportunities to become better. We’ve taken steps to inculcate a strong ‘Founder’s Mindset’ across our engineering teams, making us grow and move fast. We place special emphasis on the continuous growth of each team member - and we do this with regular 1-1s and open communication. As a Security Engineer, you will be part of self-starters who thrive on teamwork and constructive feedback. We know how to party as hard as we work! If we aren’t building unparalleled tech solutions, you can find us debating the plot points of our favorite books and games – or even gossiping over chai. So, if a day filled with building impactful solutions with a fun team sounds appealing to you, join us. About the Role As a Security Engineer 3, you are a senior individual contributor who owns security outcomes end to end across one or more product areas. You operate with limited supervision, set the technical approach for your workstreams, and are a trusted second voice in design and architecture discussions. Beyond finding and fixing vulnerabilities, you drive security initiatives to closure across engineering teams, raise the bar on how we build securely, and mentor earlier-career engineers on the team. You will combine deep hands-on offensive and defensive skills with the judgment to prioritise what matters most for a platform operating at Meesho's scale. What you will do Security Architecture & Threat Modeling: Lead threat modeling and secure design reviews for complex, multi-service features, and partner with enginee
