Description

About Bask Health

Bask Health is a software platform that enables entrepreneurs, doctors, and healthcare businesses to launch, manage, and grow direct-to-consumer telehealth businesses.

Our platform brings together patient experiences, clinical workflows, pharmacy operations, and commerce tools in one place.

We're an entrepreneurial, product-focused engineering team that values ownership, technical excellence, and building software that solves real problems. Engineers work closely with product teams and company leadership, take features from idea to production, and have a direct role in shaping the platform.

Engineering at Bask is AI-first and builder-led. We use tools like Cursor and Claude Code throughout development while maintaining high standards for reliability, testing, and software quality.

About the Role

We're looking for an AI Evaluation Engineer to help ensure that AI-powered features across Bask Health behave accurately, reliably, and consistently before and after they reach production.

Bask Health supports the technology behind direct-to-consumer telehealth businesses, connecting patient experiences, merchant operations, clinical workflows, pharmacy coordination, and commerce capabilities. As we introduce more AI-powered functionality, we need dependable ways to verify that these systems work as intended under realistic conditions.

You'll build and maintain evaluation workflows that test large language models, AI assistants, retrieval systems, and automated features against clearly defined product requirements.

This is a hands-on engineering role that combines AI evaluation, software testing, automation, and production quality assurance. You'll develop test scenarios, evaluation datasets, automated checks, and tools that help engineering teams identify problems before they affect users.

Your work may include testing AI-generated responses, validating structured outputs, evaluating tool-calling behavior, checking retrieval accuracy, and identifying regressions caused by changes to prompts, models, or application code.

You'll collaborate with applied AI engineers, machine learning engineers, backend engineers, product managers, and quality-focused engineering teams to define expected behavior and translate those expectations into repeatable evaluations.

You'll also help establish processes for reviewing AI failures, documenting recurring issues, and determining whether a feature meets its acceptance criteria. You'll work with engineers to reproduce problems and verify that fixes address the underlying issue.

Because Bask operates in healthcare-related environments, you'll pay particular attention to privacy, permissions, unsupported medical claims, and AI behavior that could interfere with approved clinical or pharmacy workflows. Evaluation systems should help verify that AI features remain within their intended operational boundaries.

This position emphasizes practical testing, thoughtful engineering, and continuous improvement. You'll contribute to evaluation standards while independently implementing and maintaining the tools and tests that support AI quality.

We're looking for an engineer who enjoys finding difficult edge cases, understands how AI behavior differs from traditional deterministic software, and wants to help build products that users can depend on.

What You'll Do

• Design and implement evaluation workflows for AI-powered applications across Bask Health.
• Build automated tests for large language model outputs and AI application behavior.
• Develop evaluation datasets that represent realistic user requests and product workflows.
• Create test scenarios for patient-facing, merchant-facing, and internal AI features.
• Implement checks for response accuracy, relevance, completeness, and consistency.
• Evaluate AI-generated content for unsupported claims and misleading information.
• Test structured model outputs for schema compliance and application compatibility.
• Build evaluations for AI tool calling and authorized action execution.
• Validate that AI assistants respect application permissions and tenant boundaries.
• Test retrieval-augmented generation systems for grounding and information relevance.
• Develop regression tests that identify unexpected changes in AI behavior.
• Integrate evaluation checks into engineering development and release workflows.
• Create automated comparison tests for prompts, model versions, and configuration changes.
• Develop scripts and utilities that simplify AI evaluation execution.
• Build reporting tools that summarize evaluation results and failure patterns.
• Investigate failed evaluations and help engineers reproduce underlying issues.
• Work with product managers to define expected AI behavior and acceptance criteria.
• Collaborate with applied AI engineers to improve prompts and application logic.
• Test AI applications against unusual inputs, ambiguous requests, and difficult edge cases.
• Develop evaluation cases for prompt injection and unauthorized tool-use attempts.
• Support human review workflows for outputs that require subjective assessment.
• Track recurring AI failures and help prioritize reliability improvements.
• Monitor production evaluation signals and investigate quality regressions.
• Document test coverage, evaluation procedures, and known limitations.
• Improve evaluation efficiency, repeatability, and maintainability.
• Participate in code reviews, engineering planning, and technical discussions.
• Support controlled testing and rollout of new AI-powered features.
• Own assigned AI evaluation projects from test design through implementation, reporting, and ongoing improvement.

• Ability to evaluate AI-generated responses against expected requirements.
• Experience working with structured data and validating application outputs.
• Familiarity with regression testing and software release processes.
• Experience debugging application failures and reproducing technical issues.
• Understanding of authentication, authorization, and secure application behavior.
• Familiarity with databases and application data models.
• Experience working with Git and collaborative software development workflows.
• Understanding of continuous integration and automated testing pipelines.
• Familiarity with logging, monitoring, and production troubleshooting.
• Ability to create clear, reproducible test cases.
• Strong analytical thinking and attention to detail.
• Ability to distinguish application defects from model behavior limitations.
• Experience documenting technical issues and communicating findings.
• Familiarity with cloud-based application environments.
• Ability to collaborate effectively with engineers, product managers, and other stakeholders.
• Strong problem-solving skills and a quality-focused engineering mindset.
• Ability to independently own evaluation and test automation projects.

Nice to Have

• Experience evaluating large language models or generative AI applications.
• Familiarity with OpenAI, Anthropic, or comparable model APIs.
• Experience with LangSmith, DeepEval, Ragas, promptfoo, or comparable evaluation tools.
• Familiarity with LLM-as-a-judge evaluation techniques.
• Experience developing AI evaluation datasets and test benchmarks.
• Understanding of human evaluation and response labeling workflows.
• Experience testing retrieval-augmented generation systems.
• Familiarity with embeddings, semantic search, and vector databases.
