The Agent Research and Tooling team, part of MongoDB's AI Builder Experience organization, owns the platform layer around agents: how teams author, distribute, evaluate, monitor, and improve agent skills and agent behavior. We are hiring a software engineer to build and maintain the tooling, evaluation systems, and quality gates behind MongoDB's agent skills.
This is a software engineering role at the intersection of developer tooling, applied AI, and software quality. This role is open to remote work in Canada or can be based out of any of our Canada offices.
Design evaluation datasets and workflows that compare agent behavior against a baseline and produce actionable quality signals
Design safety and quality gates for agent-authored content: rule packs, static analysis, confidence thresholds, structured verdicts, and bounded suppression
Create CLIs, libraries, and MCP integrations that other repositories adopt and that run in local development and CI
Integrate tooling into GitHub Actions and other CI workflows, including secrets, annotations, exit codes, and artifacts




Build code-generation quality checks, such as anti-pattern catalogs and linting for AI-generated MongoDB code
How can tests verify an agent tool's structured result when item order may vary, but counts, required fields, and values must remain correct
How can an evaluation suite show whether a skill improves answers over a baseline and give authors enough signal to improve it
2+ years of experience building production software, developer tools, internal platforms, or automation systems
Software engineering fundamentals in API design, testing, error handling, and maintainability
Experience building CLIs, libraries, test infrastructure, static analysis, or CI/CD workflows
Experience reasoning about correctness and safety with ambiguous input, nondeterministic output, false positives, or untrusted content
Experience building eval harnesses, benchmark datasets, quality metrics, LLM-as-judge workflows, or
