Senior Software Engineer, Application Migration

Senior Software Engineer, App Analysis & Modelling

Mongodb

MongoDB is growing its team in Sydney, focusing on building intelligent tools that help customers understand and modernise their application codebases. The Application Modernisation Platform (AMP) guides customers through the entire journey of modernising their applications — from legacy relational platforms to modern, scalable systems built on MongoDB. The App Analysis & Modelling team owns the critical first stage of this journey: building the context that powers everything downstream. The team builds code analysis tools that construct code dependency graphs and generate deep insights for codebases, giving customers a clear understanding of their existing applications before transformation begins. The team also designs schema recommendation engines that analyse signals such as existing relational schemas and query patterns to inform data modelling decisions. Our work sits at the intersection of analysis, data modelling, and AI — helping developers make confident, data-driven decisions as they transition to MongoDB. We are looking for a Senior Software Engineer who is passionate about building scalable backend systems and applications. As we expand our use of AI to power smarter analysis and recommendations, the ideal candidate will bring strong backend engineering fundamentals with the ability to contribute across the full stack. You will collaborate closely with product management and other engineering teams to design and deliver cutting-edge features that guide customers through complex modernisation journeys. We are looking to speak to candidates who are based in Sydney for our hybrid working model.

Senior Software Engineer, Forward Deployed AI Engineer

Mongodb

MongoDB is looking for an outstanding person to join our newly created Forward Deployed Engineering team and take on a key role in our extended R&D organization. Forward Deployed Engineering is linking the work of teams engaged on application modernization roles with our Product and Engineering teams. We are looking to speak to candidates who are based in Dublin or Cork for our hybrid working model. Many organizations have built up large estates of legacy applications. Lack of scalability and resilience, long development times, operating cost, and inability to run on cloud are common issues with these applications. To address these issues, organizations are engaging in large transformational Application Modernisation programs. MongoDB is recognized as the developer data platform of choice for transactional systems that provide the best scalability, resiliency and developer experience in the cloud as well as on premises. Organizations are continuously migrating workloads from these legacy applications to new platforms, often based on microservices, using MongoDB.  Such transformations are time intensive and often risky. Tooling based on generative AI promises to accelerate these transformations in a way never seen before. Forward Deployed Engineering is responsible for exploring the possibilities of Generative AI  technologies and providing invaluable feedback to MongoDB’s R&D teams to drive future capabilities of MongoDB and the MongoDB ecosystem. Application Modernization Engineers will work alongside project teams that are executing Application Modernisation projects with customers. The successful candidate will be responsible for evaluation, build, and applying tools in modernization  projects, facilitating the usage of such tools and processes across the different project teams, identifying opportunities for tooling deployment, selecting potential 3rd party tools, contributing to the development of tooling prototypes and helping to shape the product roadmap. OUR IDEAL CANDIDATE WILL HAVE * 4+ years of experience as a field engineer or professional services consultant or full stack developer working directly with Enterprise clients  * Proficiency in Java or C#, and some familiarity with common database access patterns and frameworks in one or more of these languages * Strong knowledge about enterprise-scale software architectures, application development methodologies, and software deployment and operations * Experience developing enterprise applications using relational databases, and employing SQL and stored procedures with Oracle, MS SQL Server, Sybase and/or PostgreSQL databases * Experience of using and developing with MongoDB and JSON based Document models is highly desirable * Problem solving skills, including the ability to collaborate across disciplines and teams to come up with creative solutions to technical and business challenges * Willingness to dive into a complex domain, ask the right questions, and bring new software tools and technologies to the table to solve customer problems * Great communication skills (both spoken and written), within the team and in customer meetings * Good understanding of Generative AI concepts, tools, and services. Any experience to build new applications/tools using Generative AI is a big plus. That includes Cursor, Claude Code, Gemini, and OpenAI APIs * And finally, a strong interest in how AI supported toolchains can improve application development POSITION EXPECTATIONS * Contribute to customer application modernization initiatives at any or all phases of the application lifecycle: assessment and analysis; planning and design; data modeling; application code conversion, development, test and build; integration and release configuration, production operations, application optimisation, and best practices adoption * Test drive MongoDB migration products to deliver on customer use cases and drive adoption of the product. Deliver concise feedback to the rest of the development organisation * Work closely with Product and Engineering teams to influence the direction of the MongoDB product roadmap * Personally execute POCs including developing or extending existing tools when necessary and appropriate for customer success, with an eye towards reusability and eventual integration with our products. These are often on premises at client locations * Maintain a broad and deep technical understanding of the product line and the underlying technologies and protocols * Work as part of a wider delivery team comprising consulting engineers from MongoDB Professional Services, project managers, and account teams * Assist sales teams in evaluating opportunities with prospects and customers * Willingness to work on site with customers for 7 days per month, which includes regional travel (within Europe) SUCCESS MEASURES The Senior Forward Deployed Engineer will be successful in this role when they can execute the following strategic tasks/responsibilities: * Become an expert level user of MongoDB, and our tools current migration products * Develop a playbook for customer application modernization engagements, in collaboration with other MongoDB Engineers, Product Management and Engineering * Communicate complex technical proposals simply and convincingly to a wide range of audiences * Provide unique insight into customer needs, product requirements and strategic opportunities by contributing experience from the field * Gain the reputation as a trusted advisor with our field teams and customers * Contribute to the success of customer application migration initiatives that they support ABOUT MONGODB MongoDB is built for change, empowering our customers and our people to innovate at the speed of the market.
