Senior Engineer - Enterprise Architecture

MongoDB seeks an experienced Senior 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.

Has 6+ 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)

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 building reliable, usable software

Experience building and maintaining full-stack applications, from front-end UIs to backend API to data pipelines

Experience designing systems or services used by other engineers or teams

Knowledge of any of the following technologies: Tanstack Start, Next.js, FastAPI, React

Experience with model evaluation frameworks, vector databases, or agent orchestration tooling (e.g., LangGraph)

Familiarity with transformer architecture and model internals

Familiarity with containerized applications, Kubernetes, and ability to design CI/CD pipelines

Design and run experiments that test emerging AI capabilities against real internal use cases, before they're formally prioritized. Condense the learnings of those experiments and document them so that the knowledge can be used across the org.

Build lightweight prototypes to validate or kill ideas quickly

Stay current on new AI tooling and models, and turn relevant developments into concrete internal proof points

Partner with product, platform, and internal engineering teams to hand off validated capabilities once they're ready to move from experiment to production

Maintain technical rigor and clear documentation of findings, even for work that doesn't ship

Identify and communicate risks, unknowns, and open questions clearly to stakeholders

In three months, have run and documented at least one AI capability experiment, with a clear recommendation on whether and how to pursue it further

In three months, demonstrate the ability to move quickly from idea to working prototype

In six months, have influenced the org's roadmap or tooling direction by surfacing a capability two to three steps ahead of current need, backed by evidence from your experimentation
