About the role
MongoDB's Enterprise Architecture team runs a focused group dedicated to AI experimentation, partnering with teams across the organization including Internal Engineering. The team explores, prototypes, and validates emerging AI capabilities before they become formal roadmap priorities, working against MongoDB's AI-era data platform and Atlas cloud-native multi-cloud database. This role designs and runs experiments testing emerging AI capabilities against real internal use cases, builds lightweight prototypes, and hands off validated capabilities to product, platform, and internal engineering teams for production.
What you will do
- 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
Skills used in this role
What the employer is looking for
- 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)
- 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
Preferred qualifications
- 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
Benefits and support
- Employee affinity groups
- Fertility assistance
- Generous parental leave policy
