About Candid Health

In simple terms, healthcare in the U.S. has a massive, invisible problem behind the scenes: getting doctors paid by insurance companies is notoriously complicated. Insurance rules are constantly changing, and every bill (or "claim") requires mountains of paperwork. When mistakes happen, bills get rejected, patients end up with unexpected charges, and healthcare providers waste billions of dollars and countless hours on administrative bureaucracy instead of focusing on patient care.

That is where Candid Health steps in. Founded by former Palantir leaders who experienced these pain points firsthand, we are building the modern financial backbone for American healthcare. Instead of relying on decades-old legacy software or attempting to patch broken systems with superficial tools, we've rebuilt the underlying infrastructure from the ground up.

Our core product is an autonomous Revenue Cycle Management (RCM) platform. Powered by AI agents and a configurable rules engine, the platform unifies clinical, billing, and insurance data into a single smart system. It acts like an intelligent, automated back-office that handles complex medical claims from start to finish—submitting them accurately on the first pass, cutting down administrative costs, and dramatically increasing cash flow for healthcare providers.

Today, we are trusted by over 200 fast-growing healthcare organizations—from digital health innovators to large enterprise medical groups—processing billions in claims annually. Backed by top investors like Sixth Street Growth, Oak HC/FT, 8VC, and Y Combinator, Candid Health recently raised a $120 million Series D to fuel the AI-driven transformation of healthcare payments and eliminate administrative friction for good.

Role Overview

We are looking for a Product Security Engineer to join our team and act as a champion for security within our product engineering organization. You will be responsible for ensuring our products are designed, developed, and maintained with security as a core pillar. You will work in partnership with development squads to perform threat modeling, guide secure architecture decisions, and automate security gates in our CI/CD pipelines.

Key Responsibilities

• Security by Design: Lead threat modeling sessions during the architectural design phase of new features to identify potential risk vectors early.

• Secure Development Lifecycle (SDLC): Drive the adoption of "Shift Left" security practices, integrating security tooling (SAST, DAST, SCA) directly into developer workflows.

• Vulnerability Management: Triage, prioritize, and partner with engineering teams to remediate vulnerabilities found in code, third-party libraries, and cloud infrastructure.

• Security Tooling & Automation: Build, maintain, and tune security automation tools to reduce friction for developers while maintaining high-security standards.

• Secure Coding Standards: Develop and deliver training, coding patterns, and security guardrails to help engineering teams build resilient, secure-by-default products.

• Incident Response Support: Assist in identifying the root cause of security incidents related to product features and contribute to post-incident remediation and architectural improvements.

• Supply Chain Security: Build out processes and automation to ensure the security of open-source dependencies.

Required Qualifications

• Experience: 5+ years of experience in software engineering or security engineering, specifically focusing on product security or application security.

• Technical Skills:

  • Proficiency in one or more programming languages (e.g., Python, Go, Java, or JavaScript).

  • Deep understanding of modern web/cloud architecture (e.g., APIs, Microservices, Kubernetes, AWS/GCP/Azure).

  • Familiarity with the OWASP Top 10 and common exploitation techniques.

• Collaboration: Proven ability to influence and collaborate with engineering teams without hindering development velocity.

• Problem Solving: Strong analytical skills to evaluate complex systems and design innovative, practical security solutions.

Preferred Skills (Nice to Have)

• Experience with Infrastructure as Code (IaC) security (e.g., Terraform, CloudFormation).

• Experience in designing cryptographic implementations or secure authentication/authorization flows (e.g., OAuth, OIDC, JWT).

• Knowledge of compliance frameworks relevant to our industry (e.g., SOC2, ISO27001, HIPAA).
