Staff Software Engineer, PerformanceJudi Health is an enterprise health technology company providing a comprehensive suite of solutions for employers and health plans, including:Judi Rx, a public benefit corporation delivering full-service pharmacy benefit management (PBM) solutions to self-insured employers,Judi Health™, which offers full-service health benefit management solutions to employers, TPAs, and health plans, andJudi®, the industry's leading proprietary Enterprise Health Platform (EHP), which consolidates all claim administration-related workflows in one scalable, secure platform.Together with our clients, we're rebuilding trust in healthcare in the U.S. and deploying the infrastructure we need for the care we deserve. To learn more, visit Summary:Judi Health is building the technology infrastructure our nation needs to deliver the healthcare we deserve. The Architecture organization is responsible for the technical foundation the rest of the company builds on: the standards, patterns, and infrastructure that engineering teams use to move fast and build efficiently. The Performance team sits within Architecture's Core Platform function, owning the platform's ability to understand, measure, and enforce how systems behave under load.As a Staff Engineer in Architecture, your influence extends beyond what you ship directly. The standards you set, the patterns you establish, and the decisions you document become the reference point for how system performance is measured and managed across the organization.Claims processing, prior authorization, and supporting data products drive highly complex, data-intensive workloads where decisions across the entire database stack – including schema design, database configuration, connection management, and storage architecture – directly determine the platform's ability to deliver reliable performance under heavy read and write load. You will be directly responsible for identifying where the ceiling is, prioritizing changes that move it with minimal disruption, and driving deeper re-architecture where the problem demands it.One of your first major initiatives will be a comprehensive diagnostic of the platform's database architecture, focused on the systems powering adjudication and claims processing – the most performance-sensitive workflows on the platform. This is a deeply embedded engagement; you will work directly within these domains to understand the query patterns, connection behavior, and cluster configuration shaping how the system performs under load. From there, you will establish the benchmarking frameworks and performance baselines that give the engineering organization a reproducible way to evaluate parameter changes, query modifications, and database upgrades before they reach production.Position Responsibilities:Apply deep Postgres expertise to diagnose production performance problems by interpreting query plans, analyzing usage patterns, and evaluating how cluster configuration and architectural decisions shape system behavior at scale, then own the path from root cause to production remediationEvaluate and implement cluster topology changes and drive the architectural transformations, including the migration from synchronous to asynchronous I/O patterns, that take the platform's throughput to the next order of magnitudeBuild the benchmarking and regression-detection infrastructure that gives engineering teams a database performance signal, before changes reach productionDefine and own performance contracts for the database layer: latency targets, throughput expectations, and the SLA boundaries that upstream services build againstLead query and schema reviews for high-risk changes; own incident response for performance-related degradations and drive post-incident findings into engineering improvementsMentor and develop senior engineers on Postgres internals, query analysis, execution plan interpretation, and the performance implications of schema decisions at scaleParticipate in a 24/7 on-call rotation to provide continuous operational support and rapid incident responseRequired Qualifications:10+ years of production engineering experience, with deep specialization in PostgreSQL performance and transactional systems at scaleDeep fluency in PostgreSQL internals: MVCC, autovacuum behavior, query planner statistics, locking semantics, and the interaction between transaction patterns and long-running queriesDemonstrated ability to diagnose and remediate production database performance problems in regulated or correctness-critical environments where performance improvements cannot compromise data integrityExperience designing and building performance benchmarking and regression-detection systems – including CI-integrated performance gates and observability pipelines – that give engineering teams pre-production visibility into database performance across the stackExperience evaluating and implementing cluster topology changes: connection pooling configuration, read replica strategy, partitioning/sharding approaches, and PostgreSQL - parameter tuning for high-concurrency transactional workloadsA track record of leading cross-team technical initiatives – driving decisions through influence and producing documentation that holds up over timeStrong written and verbal communication – you produce architectural guidance that the broader engineering organization depends onComfortable operating with ambiguity – at this level, you will be handed problems, not plans, and are expected to identify the right approach and drive it from first principles to productionStrong experience supporting 24/7 production on-call rotations, including responding to alerts and resolving incidents outside of standard business hoursPreferred Qualifications:Direct experience with Aurora PostgreSQL at scale, including familiarity with the operational constraints of a managed PostgreSQL deployment: connection limits, storage autoscaling behavior, I/O throughput ceilings, extensions, and the performance characteristics of Aurora's distributed storage layerHands-on experience with connection pooling middleware, particularly the operational tradeoffs between pooling modes (session, transaction, statement) in high-concurrency transactional workloads; e.g. PgBouncer, PgDog, or equivalentExperience with asynchronous Python I/O patterns (asyncio, asyncpg, or equivalent) and the architectural migration from synchronous to asynchronous database interactionFamiliarity with horizontal scale strategies for transactional PostgreSQL workloads, including logical and physical sharding approaches and the tradeoffs they introduce for data model complexity and query routingFamiliarity with the boundary between OLTP and OLAP workloads, and the ability to recognize when analytical query patterns are better served by a purpose-built system than optimized on the transactional clusterSystems-level programming experience in Rust, Go, or C/C++. While the primary focus of this role is database optimization, you'll be actively involved in application development, and the ability to work at lower levels of the stack when performance demands it is a meaningful advantageBackground in pharmacy benefit management, claims adjudication, healthcare data systems, or other regulated, correctness-first transactional environmentsNew York, NY Salary Range: $200,800 - $251,000 USDDenver, CO Salary Range: $184,000 - $230,000 USDCharlotte, NC Salary Range: $167,200 - $209,000 USDAll employees are responsible for adherence to the Judi Health Code of Conduct including the reporting of non-compliance.
