Job description

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.

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.

Why Join Assured

• High-impact work — Tackle bottlenecks that slow down provider access to patients
• Real-world AI — Build intelligent systems that reason, act, and automate in production.
• Cross-functional exposure — Collaborate with customers, clinical ops, engineers, and founders
• Early-stage upside — Equity, early influence, and a high-growth trajectory
• People-first culture — Mental health time, and a focus on outcomes, not hours

Benefits and Pay

Our headquarters are located in New York City. This is an in-office role. We value in-person collaboration — we host offsites, outings, and team meals to stay connected as people, and offer office lunch and a fully stocked snack bar. We provide competitive base compensation along with stock options. Compensation for this role depends on experience and interview performance. We offer generous employer-sponsored health and dental coverage, nine company holidays, and unlimited PTO (take what you need).
