Our mission is simple: make healthcare data usable, so the people responsible for care and cost decisions can act faster, with confidence.\nAs the AI and Data Platform for Payer Intelligence, we help health plans break down data silos to create a single, trusted data foundation. That foundation powers better decisions-so plans can improve outcomes, reduce waste, and deliver better experiences for members and providers alike. Backed by $100M from top investors, we're tackling big challenges in an industry that's ready for change. Our platform enables GenAI use cases by delivering clean, connected, and reliable healthcare data to support automation, prioritization, and decision workflows-and it's why we are leading the way.\nOur innovation begins with people. We are bold, curious, and collaborative-because the best ideas come from working together. We embrace the thoughtful use of AI and automation to drive innovation and efficiency, and we look for individuals who are curious and adaptable-those excited to leverage emerging technologies to enhance how we work-while keeping human insight, connection, and our clients at the center of every decision.\nReady to make an impact? Join us and let's build the future together.\nAbout the Role\nAt Abacus Insights, we’re building AI-powered platforms that sit at the center of critical healthcare decisions-where reliability, correctness, and trust matter as much as innovation. As our use of agentic, LLM-driven systems scales, ensuring these systems behave safely and predictably in real-world environments isn’t optional-it’s foundational. \nThe Senior AI Systems Quality Engineer plays a critical role in making our AI systems production-ready, operable, and trustworthy. This is not a traditional QA role. Instead, you’ll help define how quality is engineered into agentic systems from the very beginning-embedding guardrails, evaluation signals, and safe-failure behavior directly into how these systems are designed, built, and deployed. In this role, you will also help design and own an AI testing platform that operates natively within our Databricks Medallion architecture-leveraging tools like MLflow to enable evaluation, lineage, traceability, and auditability at scale. This is a platform-oriented role, focused on establishing repeatable, scalable quality practices rather than point-in-time validation.\nYou’ll partner closely with AI Engineers, platform teams, and delivery stakeholders to design custom evaluation frameworks, validation pipelines, and automated testing harnesses that reflect how agentic systems behave in production. You’ll focus on validating orchestration logic, managing non-deterministic behavior, and ensuring AI systems degrade safely under uncertainty, scale, and failure.\nThis role is automation-first by design. You will build end-to-end automated AI testing integrated into the development lifecycle, where validation is continuously enforced-not manually reviewed after the fact. Your work will directly influence release readiness, operational confidence, and Abacus’ ability to responsibly deploy advanced AI in mission-critical healthcare environments.\nIf you believe quality is a core engineering discipline-not a downstream checkpoint-this role gives you the opportunity to shape how reliable, governed, and scalable agentic AI is built from the ground up.\nYour day to day\nBuild and ship production-grade, automated validation frameworks, test harnesses, and evaluation pipelines across the AI lifecycle (design → deploy).\nDesign and evolve an AI testing platform integrated with Databricks and MLflow, enabling repeatable testing, traceability, and auditability.\nCreate large-scale, scenario-based test suites (hundreds to thousands of cases) to validate agentic workflows end-to-end, including edge cases, long-tail scenarios, and failure modes.\nValidate orchestration behavior (tool use, memory, decision logic) and stress-test non-deterministic system behavior before production.\nEmbed quality by design: define system contracts, guardrails, and safe-degradation patterns at key boundaries.\nDefine measurable quality signals for LLM systems (grounding, hallucinations, relevance, latency, cost) and integrate them into CI/CD pipelines as automated quality gates.\nEnsure AI validation runs automatically on model, prompt, and code changes-enabling continuous quality enforcement.\nBuild reusable libraries and components so teams can adopt consistent AI quality practices quickly.\nOwn aspects of AI release readiness, including defining go/no-go criteria based on measurable quality thresholds.\nPartner with AI, platform, security, and delivery teams to translate mission needs into clear quality criteria, tradeoffs, and confidence levels.\nWhat you bring to the team\n7+ years of software engineering experience, primarily in backend or platform systems.\nProven experience designing and implementing AI testing automation in production environments, not just executing tests.\nDemonstrated ability to build custom validation, evaluation, or testing frameworks for complex, distributed systems.\nStrong proficiency in Python and/or TypeScript within modern AI engineering stacks.\nHands-on experience with AI-powered systems, including LLM-based or agentic workflows and non-deterministic behavior.\nExperience designing or contributing to AI testing at scale, including regression frameworks, long-tail evaluation, and large test coverage.\nDeep understanding of CI/CD integration, including embedding automated tests and quality gates into deployment pipelines.\nSolid understanding of AWS cloud-native architectures.\nTrack record of engineering for quality, reliability, governance, and safety as core system design principles.\nWorking knowledge of security, privacy, and operational risk in regulated or mission-critical environments, including failure modes and recovery.\nExperience with AI testing methodologies, including evaluation of non-deterministic outputs, drift detection, bias/fairness testing, and robust regression strategies.\nProven ability to establish measurable trust thresholds for AI systems, including defining and operationalizing success metrics such as query accuracy, hallucination limits, explainability, and PHI-safe behavior as enforceable release criteria.\nExperience working with domain experts to define correctness and real-world validation scenarios, enabling large-scale, business-relevant test coverage that reflects true production use cases rather than engineering-only perspectives\nWhat we would like to see, but not required\nExperience with Databricks-native environments and Medallion architecture.\nExperience using MLflow for model evaluation, lineage tracking, and auditability.\nExposure to observability tools (e.g., Datadog, Prometheus, Grafana) for distributed AI workflows.\nFamiliarity with LLM evaluation techniques, guardrails, and policy enforcement frameworks.\nExperience evaluating performance, latency, or cost regressions in AI systems.\nAbility to clearly document system behavior and quality trade-offs for technical and business audiences.\nFormal training or certification in AI/ML systems (e.g., ISTQB AI Testing, AWS ML Specialty, Google ML Engineer).\nExperience designing and iterating on prompts, agent behaviors, and orchestration logic as versioned, testable artifacts, enabling rapid refinement of AI system behavior (often referred to as “vibe coding”) without heavy reliance on traditional code changes.\nFamiliarity with using AI systems to generate and expand test scenarios, including creating large-scale, diverse, and adversarial test datasets to significantly improve coverage and validation depth.\nCompensation: Compensation for this role is based on experience, skills, and location, and includes base salary plus eligibility for performance bonuses and equity grants.\nWhat you’ll get in return:\nUnlimited paid time off - recharge when you need it\nWork from anywhere - flexibility to fit your life\nComprehensive health coverage - multiple plan options to choose from\nEquity for every employee - share in our success\nGrowth-focused environment - your development matters here\nHome office setup allowance - one-time support to get you started\nMonthly cell phone allowance - stay connected with ease#\nOur Commitment as an Equal Opportunity Employer\nAs a mission-led technology company helping to drive better healthcare outcomes, Abacus Insights believes that the best innovation and value we can bring to our customers comes from diverse ideas, thoughts, experiences, and perspectives.
