Lead Platform Engineer, Application Modernization

The Application Modernization Platform (AMP) team is dedicated to solving one of the industry's biggest challenges: transforming rigid, legacy applications that suffer from poor scalability and high operating costs into modern, microservices-based architectures on MongoDB. To accelerate this transition, MongoDB is building a dedicated Platform and Operations team to develop the Application Modernisation Platform. As we help customers modernize their application and data ecosystems, we face the challenge of deploying complex tooling into highly restrictive client environments.

This new team will architect the platform foundation and infrastructure that enables a "build once, run anywhere" model, ensuring our AI-powered modernisation suite operates seamlessly regardless of a client's security or network constraints. We are looking for engineers to join this high-visibility initiative, where you will solve unique distributed systems puzzles and help shape the future of how global enterprises leverage data and AI.

We are looking for an experienced Lead Software Engineer who thrives on solving infrastructure constraints and building developer-centric modernisation platforms.

The ideal candidate is a hands-on technical leader who can architect complex distributed systems, mentor engineers, and collaborate with product teams to deliver a platform that minimizes deployment friction and protects MongoDB’s IP.

We are looking to speak to candidates who are based in Gurugram for our hybrid working model.

Position Expectations

• Provide technical leadership and mentorship to a team of engineers, fostering a culture of innovation, quality, and continuous improvement


• Drive the architectural vision for the Application Modernisation Platform, ensuring it supports a self-service SaaS product model while operating within client-controlled environments


• Lead the design and implementation of a sophisticated orchestration layer that manages authentication, telemetry, and the lifecycle of modernization tools


• Architect a client-side application that manages developer workflows and communicates securely with hosted services


• Solve complex "Day 2" operations challenges, such as designing interfaces to solve DevOps challenges to manage users, secrets, and updates


• Collaborate with security and product teams to ensure the platform can execute code generation and LLM-based tasks securely, protecting both client data and MongoDB IP


• Act as a hands-on leader, guiding the team through technical challenges related to container security, local vs. hosted logic distribution, and cross-service data sharing

The ideal candidate for this role will have

• 8+ years of software development and operations experience, with a focus on building internal developer platforms (IDP) or distributable software infrastructure


• 2+ years of experience leading, coaching, and mentoring a team of engineers to achieve high-impact results


• Deep experience designing distributable applications that run in air-gapped or highly restricted network environments


• Strong proficiency in containerization and orchestration, with the ability to design systems where the host executes containerized applications under strict security monitoring


• Experience building Service Host architectures that provide shared routing, proxy layers, and API gateways for multiple underlying services


• Experience managing persistent storage solutions (blob/file storage) within distributed systems


• Understanding of security-first design, specifically regarding the execution of untrusted code, fine-grain access control, and rigorous input validation


• Experience designing auto-update mechanisms for software that cannot directly access the public internet


• Curiosity, a positive attitude, and a drive to continue learning

Success Measures

Within the first three months, you will have

• Fully ramped up on our architecture, business domain, and the specific constraints of deploying software to large enterprise client environments


• Established yourself as the technical leader within the team, actively driving technical discussions on the Service Host and Local Orchestrator architecture


• Begun mentoring team members and collaborating with product counterparts to define the boundaries between the platform and the tools it hosts

Within six months, you will have

• Successfully led the team to deliver a prototype or initial release of the Deployment Platform that supports the core Modernization toolset.


• Designed and implemented a streamlined process for platform updates that works within client security constraints


• Established a precise rhythm of execution and a high-performing culture within your team

Within 12 months, you will have

• Become recognized as the go-to technical expert for the deployment and operations domain at MongoDB


• Delivered a stable, production-ready platform that allows our Field Engineering teams to deploy tools without significant delays or approvals


• Played a crucial role in recruiting, hiring, and growing the engineering team
