Job Summary
Designs, develops and deploys the evaluation and trust capabilities of Equinix's GenAI platform. Builds platform features that let teams evaluate their agents at scale: golden datasets, synthetic test data, scoring with LLM-as-judge, and monitoring of agent quality in production. Builds and tests the trust controls that agents run on, including agent identity, access, guardrails and data boundaries. Traces agent failures to their root cause and fixes them in the platform. Works in a team with senior engineers and with product, platform and security partners to turn defined problems into robust, secure, observable and performant solutions.
Knowledge and Application
Applies solid knowledge of software engineering practice and of LLM and agent concepts (prompting, retrieval, tool and function calling, orchestration, MCP). Understands evaluation methods (code-based checks, LLM-as-judge, human review, golden datasets, regression suites) and evaluation statistics (sampling, variance across runs, agreement between reviewers). Understands AI security risks such as prompt injection and data leakage, and identity concepts such as OAuth and per-user access. Follows established standards and suggests improvements.
Complexity and Problem Solving
Works on problems of defined scope where analysis requires evaluation of identifiable factors. Traces an agent failure to its cause (retrieval, tool call, prompt, model, data or infrastructure) using logs and traces, and follows it until it is fixed. Judges whether a metric reflects real quality. Escalates unusual or high-impact issues. Work is reviewed at defined checkpoints.
Collaboration and Interaction
Works with AI engineers, product managers, forward-deployed engineers, platform and security teams. Turns the needs of agent builders into platform features. Explains results, defects and risks to partners who are not familiar with the subject. Asks for guidance early and shares knowledge with the team.
Evaluation platform (primary focus)
Build platform features for evaluation: dataset creation and versioning, golden datasets, synthetic test data and reusable metric templates
Build scoring for agents: code-based checks, LLM-as-judge, tool-call accuracy and grounding checks
Build human-review features that compare judge scores against human reviewers, and recalibrate when agreement is low
Run evaluations at scale: before release, on every change to a prompt, model or tool, and on agents in production
Build evaluation playbooks so agent builders can evaluate their agents without specialist help
Keep results traceable to the agent, model, prompt and dataset versions tested, with a record of who approved each release
Trust and safety
Build and test the platform's trust controls: agent identity, per-user access to connected systems, tool permissions, guardrails and data boundaries
Run adversarial tests and red-teaming (prompt injection, out-of-scope requests, data-boundary tests), and turn findings into fixes and regression tests
Work with security and governance teams to turn policy requirements into automated checks
Root-cause analysis and quality
Investigate agent failures and performance problems end to end, and follow them until the cause is fixed
Build test and performance tooling: end-to-end agent tests, load and latency tests, and failure diagnostics
Turn production failures and user feedback into regression tests, so the same defect does not return
Quality and responsible practice
Write tested, reviewed and documented code, and contribute to shared libraries and tooling
Test and build to security, data-privacy and responsible-AI requirements
Required
1–4 years in AI/ML or software engineering (internships and applied research count)
Bachelor's degree in computer science, engineering, data science, mathematics or a related field, or equivalent experience
Proficiency in Python, with solid habits: version control, testing, code review. Experience building backend services or platform features
Hands-on experience building, not only using, evaluations or test systems for ML or LLM applications, including reading failures from logs or traces
Working knowledge of LLM applications (prompting, retrieval, agents)
Working knowledge of evaluation statistics (sampling, confidence intervals, variance across runs) and of measuring agreement between reviewers
Ability to write SQL and analyze results
Clear written and verbal communication
Nice to have
Experience building evaluation or observability features used by many teams or at scale
Experience with LLM evaluation and observability tools, and tracing standards such as OpenTelemetry
Experience with red-teaming or adversarial testing of LLM systems
Experience with identity and access (OAuth 2.0, OIDC, delegated access)
Experience with performance, load or test engineering
Experience with agent frameworks, MCP or A2A
Experience with Google Cloud (Vertex AI, GKE) and Kubernetes
Familiarity with AI risk frameworks (NIST AI RMF, ISO 42001)
MS in a related field
What success looks like
Platform features ship on schedule, with tests and documentation
Teams can evaluate their agents on the platform without specialist help
Every agent release carries an evaluation record with criteria, results, open defects and approver
Judge scores agree with human reviewers, and teams use them to make release decisions
Trust controls are enforced by the platform and covered by automated tests
Defects found in evaluation become regression tests, and the same defect does not return
The engineer takes on larger, less defined work each quarter with decreasing guidance
