Staff Software Engineer, Fullstack

About Assured is transforming the infrastructure of U.S. healthcare using intelligent automation. We’re building an AI-native system of action for provider operations to automate the most painful parts of healthcare, starting with credentialing, licensing, and payer enrollment. These are slow, error-prone processes that cost the healthcare system billions and delay patient care. We’re backed by top Silicon Valley investors and trusted by the most innovative provider groups and health systems. This is a rare opportunity to join an elite team reimagining one of the most broken parts of healthcare - using cutting-edge AI in the real world, at scale. The Role: Software Engineer We’re looking for a Software Engineer to help architect, build, and productize our AI/ML infrastructure. You'll be the bridge between research, product, customers, and engineering, driving AI adoption from strategy through production at scale. This role is ideal for someone who thrives in early-stage environments, enjoys owning things end to end, and wants their work to have a measurable impact on an industry that desperately needs modern infrastructure. What You’ll Do System Architecture & Design Design and evolve a modular, service-oriented architecture to power configurable healthcare workflows at scale. Build a workflow orchestration engine capable of handling thousands of concurrent stateful tasks (credentialing, verification, enrollment). Define and optimize integration frameworks to connect with thousands of external systems — web portals, APIs, PDFs, spreadsheets. Drive reliability, auditability, and performance through observability, self-healing, and clear fault-domain boundaries. Applied AI and Automation Lead the design and deployment of AI-powered digital workers — LLM- and rules-driven agents that perform operational workflows end-to-end. Evaluate AI tools, frameworks, and third-party APIs, ensuring alignment with platform goals and data protection requirements. Cross-functional Leadership Partner with product, engineering, and analytics to discover use cases, build features, and deliver value Engage with customers to understand operational challenges, validate assumptions, and iterate solutions quickly What We’re Looking For Must-Have: 5+ years experience building and scaling complex, distributed systems or workflow-heavy SaaS platforms. Proven ability to own architecture and make high-stakes technical decisions in ambiguous, high-growth environments. Deep understanding of modern cloud architecture and full software stacks. Excellent communication — able to clearly explain technical trade-offs to technical and non-technical audiences alike. Preferred: Experience with workflow orchestration frameworks or event-driven architectures. Contributions to open-source projects, publications, or active technical presence. Open-source contributions, publications, or technical blog presence You’ll Love This Role If You Want to lead AI projects from idea to deployment Want to own architecture, projects, and culture — not inherit them. Thrive in a 0→1 environment , building from scratch and scaling from concept to production. Care deeply about impact — accelerating patient access by fixing the infrastructure of healthcare. Believe great products emerge from tight collaboration between product, engineering, and operations. Want your work to outlast you — building systems that become part of healthcare’s invisible infrastructure.
