Senior Full Stack Developer

We’re building a large healthcare portal and the services behind it — a React web application, a suite of embeddable micro-frontend widgets, and a serverless Python API layer on AWS. You’ll own a significant area of this platform end to end: shaping the design, writing the code, securing it, shipping it through CI/CD, and operating it in production.

This is a true full-stack role — frontend and backend are equally important, and you’re expected to be effective across both. You’ll move comfortably between a React UI, the serverless APIs behind it, and the infrastructure that runs it all.

This is a senior role for someone who can take an ambiguous problem, drive it to a well-architected solution, and deliver with minimal oversight. You’ll set technical direction in your area, raise the quality bar, and mentor others — not wait to be handed tickets.

Responsibilities

• Own a domain end to end across the full stack — from the React UI through the serverless API to the data and infrastructure that backs it.
• Build and maintain features in a React single-page application and a family of independently deployable micro-frontend widgets that embed into it.
• Design and implement Python serverless APIs (AWS Lambda behind API Gateway), with typed request/response models and an OpenAPI contract as the source of truth.
• Build and evolve identity and authorization — OAuth2/OIDC sign-in, MFA, token validation, and fine-grained, entitlement-based access control (including delegated/third-party access scenarios).
• Integrate with upstream enterprise APIs: model their contracts defensively, handle partial/missing data gracefully, run calls concurrently, and keep changes backward-compatible.
• Design data and caching layers (e.g., DynamoDB), manage secrets, and tune performance and reliability of your services.
• Harden everything for a regulated, PII/PHI-sensitive environment — data masking, least-privilege access, secrets management, and secure handling of personal data by default.
• Own your CI/CD: automated linting, type-checking, tests, security scans, and infrastructure changes through to production.
• Define and evolve infrastructure as code, and participate in operational ownership of your services.

Qualifications

• 7+ years of professional software engineering experience, including significant experience delivering modern full-stack web applications in production environments.
• Strong hands-on experience building frontend applications with React, TypeScript, and modern single-page application architectures.
• Proven experience designing and developing backend services using Python, including RESTful APIs, service integration, and API contract-driven development.
• Deep experience with AWS cloud services, including AWS Lambda, API Gateway, DynamoDB, IAM, CloudWatch, and related serverless technologies.
• Strong understanding of authentication and authorization technologies, including OAuth 2.0, OpenID Connect (OIDC), MFA, token-based security, and role- or entitlement-based access controls.
• Experience implementing secure software solutions in environments containing sensitive customer, healthcare, financial, or regulated data.
• Demonstrated expertise with CI/CD pipelines, automated testing, code quality controls, security scanning, and release automation.
• Hands-on experience with Infrastructure as Code (IaC) using tools such as Terraform, AWS CDK, CloudFormation, or similar technologies.
• Experience designing scalable data solutions using NoSQL and/or relational databases, including performance optimization, caching strategies, and data modeling.
• Strong understanding of software engineering best practices, including system design, automated testing, observability, resiliency, and production support.
• Proven ability to lead technical initiatives, independently drive ambiguous requirements to implementation, and make architectural decisions with minimal oversight.
• Experience mentoring engineers, conducting code reviews, and influencing engineering standards and technical direction across a team.
• Excellent written and verbal communication skills, with the ability to collaborate effectively across product, engineering, architecture, security, and business stakeholders.
