Job description
OVERVIEW
Backed by a major non‑profit healthcare consortium, our client is a newly formed, well‑funded healthcare technology spin‑off on a mission to fix a fundamentally broken industry. They are building the universal operating system for healthcare—an AI‑native, event‑driven platform connecting payers, providers, and patients. This is not about maintaining legacy systems; it is about building a disruptive, intelligent data hub from the ground up.
This is a hands‑on, coding‑heavy Principal role for a builder, not an enterprise architect. You will write production code every day across the full platform—front‑end, back‑end, and full‑stack work spanning AI and chat, document processing, analytics, and claims processing, all on a single modern tech stack. You will architect where it matters (assembling high‑performance services, designing database schemas), but architecture is one part of the job, not the whole job.
The environment is startup‑minded with CI/CD and full end‑to‑end ownership. Developers own setup, testing, and integration testing without handing work off across silos, which lets the team move faster than a traditional enterprise structure allows. We are looking for self‑driven engineers who push back with suggestions rather than waiting for direction.
Must be eligible to work on W2 without sponsorship. Not eligible for C2C.
Pay Rate: $85–$100/hr
Duration: 6‑month contract‑to‑hire
Location: Hybrid; 2×/week in office—San Diego, Long Beach, Sacramento, Rancho Cordova, or Oakland (SF Bay Area)
RESPONIBILITIES
Write production code daily in Node.js and TypeScript to build scalable, cloud‑native applications across all platform products.
Build back‑end services, APIs, and front‑end components in React, working as a full‑stack contributor rather than within a single silo.
Build secure, high‑scale enterprise APIs and integration layers, including API gateways and event‑driven systems.
Own work end to end—setup, development, testing, and integration testing—within a CI/CD and DevSecOps workflow.
Architect high‑performance services and design database schemas as part of building, not as a separate hand‑off.
Incorporate AI capabilities and real‑time data streaming into the platform.
Work within Azure using Kubernetes (AKS), Docker, and Terraform to deploy and scale applications.
Provide proactive, tech‑lead‑caliber reporting and guide other engineers through code reviews and best practices while remaining deeply hands‑on in the code.
QUALIFICATIONS
10+ years of software engineering experience, currently hands‑on at a Senior, Staff, or Principal level. This is a builder role; candidates whose recent work is primarily architecture or oversight are not a fit.
Deep, current expertise in Node.js and TypeScript. This is the core stack; Java and .NET / C# backgrounds are not a match.
Strong front‑end experience with React.
Deep experience building APIs and back‑end services.
Self‑driven working style with a track record of proposing improvements and pushing back constructively rather than waiting for direction.
Strong communication skills with proactive, tech‑lead‑caliber reporting expected at the principal level.
Cloud‑native development experience in Azure, hands‑on with Kubernetes (AKS), Docker, and Terraform (Infrastructure as Code).
System Design & Platform Experience
Experience building multi‑tenant SaaS platforms.
Strong understanding of data isolation, scalability, and system design.
Experience with event‑driven architecture and integrations.
Nice to Have
AI integration experience.
API gateways / MuleSoft.
Healthcare or other regulated environments (HIPAA, SOC 2).
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, disability status, or other non‑merit factor. We are committed to creating a diverse and inclusive environment for all employees.
