Description

At RXNT, we offer a rare engineering environment: the lean, fast, and iterative velocity of a mission-driven startup, backed by our stability as a 26-year-old industry leader. We serve as the digital backbone of the U.S. healthcare system, empowering healthcare professionals to deliver better patient care when it matters most. We are not here to maintain the status quo. The healthcare landscape is evolving rapidly, demanding platforms that are performant, highly secure, and deeply intelligent. We are aggressively modernizing our core cloud-based applications and building advanced, AI-native clinical products from the ground up. You will tackle complex data workflows, engineer high-availability systems, and solve deep architectural challenges that securely transform unstructured information into trustworthy clinical data and actions, helping the healthcare providers focus on what matters the most, the patient. Transforming healthcare is both a profound privilege and a serious responsibility. It requires us to uphold the highest technical standards, think with rigor, and move with extreme urgency because patients’ health and their care process depend on it. If you are an engineer who high-stakes teams and projects rely on and looking for true end-to-end ownership, where your architectural decisions have an immediate, real-world impact without the bureaucratic red tape, this is where you belong.

What True Ownership Looks Like Here

• Own the End-to-End Outcome: You won't just be handed a ticket to code; you will own the entire lifecycle of complex technical challenges from initial architecture to deployment and monitoring. You will operate with the lean, iterative speed of a startup, delivering features that directly impact the U.S. healthcare ecosystem.
• Architect Advanced AI-Native Solutions: Rather than simply consuming AI as a tool, you will build and integrate the foundational agents, services, and infrastructure that power our intelligent clinical products. You will solve deep architectural problems to securely transform unstructured data into reliable, scalable solutions for the healthcare industry.
• Engineer for Uncompromising Reliability: Because our platform supports healthcare providers when it matters most, our standards for system health are absolute. You will independently design, test, and scale high-availability systems, aggressively modernizing core applications and eliminating structural inefficiencies.
• Drive Delivery and Close the Gaps: You will work in harmony with product and engineering teams to shape raw, undefined problems into precise, scalable solutions. We expect you to proactively identify bottlenecks, close every technical loop, and mentor peers to continuously elevate the team's engineering bar.

The Mindset & DNA We Need

• Relentless Attention to Detail: You obsess over accuracy and precision. You have a disciplined habit of closing all loops and gaps, ensuring absolutely nothing falls through the cracks when building systems that patients and providers rely on.
• Objective & Ego-Free: You thrive in a culture rooted in openness and respect. You are highly comfortable giving and receiving direct, objective feedback, viewing it as the fastest path to technical excellence rather than a personal critique.
• Pragmatic First-Principles Thinking: You comfortably navigate ambiguity, moving efficiently to solve complex problems without needing your hand held. You break down raw problems to their core elements, balancing fast execution with the uncompromising reliability required in healthtech.
• Unwaveringly Mission-Focused: Your sense of ownership extends beyond the codebase to the ultimate success of the product and the company. You keep your eyes fixed on the overarching goal, ensuring that every technical decision you make directly advances our real-world impact.
• Continuous Growth: You actively digest the latest technologies, engineering practices, and architectural patterns. You are a lifelong learner who adapts quickly to new challenges and proactively shares your expertise to elevate the entire team.

Key Responsibilities

• Own the Problem Space: Translate ambiguous product concepts into concrete ML strategies. You will start deep in the data, conducting rigorous EDA, uncovering patterns, and identifying features—long before you write production code.
• Architect for Healthcare: Fine-tune multi-modal generative models and orchestrate sophisticated AI agents (e.g., LangGraph) with a deep respect for the domain. You will prioritize precision, test relentlessly for edge cases, and build fallback heuristics.
• Establish Rigorous Evals: Define strict statistical and business metrics from day one. Build robust evaluation frameworks to ensure models meet the high-stakes reliability required in healthtech.
• Ship & Monitor: Write production-grade Python and collaborate with engineering to deploy scalable solutions. You own the post-deployment reality: work with engineering and ops to build monitoring for system health, track data drift, catch model degradation, and more.
• Communicate & Execute: Operate with deep focus and autonomy. Proactively align with stakeholders and deliver crisp, concise, results-driven updates to technical leadership.

Skills, Knowledge and Expertise

• Experience: 5+ years of shipping production-grade software in complex, high-stakes environments. You possess a deep foundation in computer science principles and can demonstrate a track record of architecting performant, highly scalable web applications, rather than just contributing to them.
• Advanced AI-Native Workflow: You are far past treating AI as a simple assistant. You understand the underlying mechanics and best practices of modern AI assistants (Claude, Copilot) to achieve fast-paced delivery without sacrificing an ounce of quality. You don't just throw ambiguous problems at an agent; you rigorously structure technical plans and specs to guide them effectively, ruthlessly verifying the generated code against your own high standards.
• Deep Systems Mastery: Expert-level command of modern backend languages (e.g., C#, Node.js, or Python) and frontend architectures. You understand the underlying abstractions, microservices design, RESTful APIs, and how to structure clean, maintainable code.
• Cloud & Infrastructure Understanding: While we have dedicated SREs, you are expected to truly own your payloads. You possess strong cloud understanding and are ideally familiar with Infrastructure as Code (e.g., Terraform).
• Observability & Testing: You instrument your code for the real world. You have practical expertise with modern monitoring and logging tools (e.g., Datadog, New Relic, or similar) to track down anomalies before they become critical bugs, backed by rigorous unit and integration testing.
• Bonus Qualifications: Previous experience leading complex technical projects from 0 to 1, mentoring peers, or a background working within the healthcare industry.

Benefits

• RXNT offers employees access to medical insurance, short and long term disability, as well as the potential to earn quarterly incentives based on the company's performance.
