Software Engineer 3 - Enterprise ArchitectureNew

The opportunity

MongoDB seeks an experienced Software Engineer to join Enterprise Architecture on a focused team dedicated to AI experimentation. You'll partner with teams across the organization, including Internal Engineering, to explore, prototype, and validate emerging AI capabilities before they become formal roadmap priorities.

What you'll do

  • Has 2-5 years of professional software engineering experience

  • Deep experience with at least one modern programming language (Python, Typescript, Go, Rust, etc.)

  • Strong technical judgment and the ability to independently solve complex engineering problems

  • Excellent communication skills and comfort collaborating across teams and disciplines

  • Comfortable operating in ambiguity, scoping and running experiments when the right approach isn't known yet

  • Hands-on experience prototyping with LLMs or agentic systems (evals,: fine-tuning, RAG, tool use, orchestration frameworks)

What they're looking for

  • Has the ability to iterate fast, specially in the case where requirements are not clear
  • Keeps up with emerging AI tooling and models, not just what's already mainstream
  • Collaborative, detail-oriented, and passionate about developing usable software
  • Experience building and maintaining full-stack applications, from front-end: UIs to backend API to data pipelines
