Senior Software Engineer, Code Generation

MongoDB's mission is to empower innovators to create, transform, and disrupt industries by unleashing the power of software and data. We enable organizations of all sizes to easily build, scale, and run modern applications by helping them modernize legacy workloads, embrace innovation, and unleash AI. Our industry-leading developer data platform, MongoDB Atlas, is the only globally distributed, multi-cloud database and is available in more than 115 regions across AWS, Google Cloud, and Microsoft Azure. Atlas allows customers to build and run applications anywhere-on premises, or across cloud providers. With offices worldwide and over 175,000 new developers signing up to use MongoDB every month, it's no wonder that leading organizations, like Samsung and Toyota, trust MongoDB to build next-generation, AI-powered applications.

MongoDB is seeking a Senior Software Engineer with advanced software engineering skills and experience in code modernization & building tools that can traverse code structures programmatically. Joining this team, you'll be pivotal in a product engineering group dedicated to helping users navigate code conversion challenges with AI's support.

We are seeking candidates located in North America for in-office, remote, or hybrid work options.

Many organizations have built up large estates of legacy applications. Lack of scalability and resilience, long development times, operating costs, and inability to run on the cloud are common issues with these applications. To address these issues, organizations are engaging in large transformational Application Modernization 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 and on-premises. Organizations continuously migrate workloads from these legacy applications to new platforms, often based on microservices, using MongoDB.

Such transformations are very time-intensive and often risky. MongoDB is bolstering its team by creating tools that guide customers in transitioning their applications from relational databases to MongoDB. As businesses evolve their application development frameworks, they're increasingly drawn to the versatility of the document model. The Application Modernization team, already instrumental in this area, aids developers in making the shift from relational databases to MongoDB via Relational Migrator ( . Now, they're broadening their toolkit and are keen on modernizing code using a mix of AI and traditional text processing.

Our ideal candidate will have

5+ years of experience in JAVA in building large-scale enterprise applications

Proficiency in Javascript and familiarity with common database access patterns and frameworks in one or more languages

Knowledge of 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 in using and developing with MongoDB and JSON-based Document models is highly desirable

Experience with tools and methodologies for code analysis, refactoring, and automated testing

Problem-solving skills, including collaborating across disciplines and teams to devise 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 solve customer problems

Excellent communication skills (both spoken and written), within the team and in customer meetings

A good understanding of Generative AI concepts, tools, and services is a big plus, as is any experience building new applications/tools using Generative AI

A strong interest in how AI-supported toolchains can improve application development
