About CredFlow AI
CredFlow AI is transforming healthcare operations by building an AI co-pilot that automates credentialing, payer enrollment, and provider data management. Our platform replaces outdated manual processes with intelligent automation — reducing compliance risks, improving accuracy, and eliminating delays in onboarding and data workflows. By ensuring real-time data consistency across healthcare networks, CredFlow AI strengthens provider–payer relationships and enables healthcare teams to focus on what matters most: delivering better patient care.
About the Role
We're looking for an Associate Backend Engineer at the start of their career — someone who has built a few things (in an internship, at a first job, or through serious side projects) and is ready to grow fast in a real product environment.
You'll work on the services that power our platform — Node.js APIs, real databases, background jobs, and third-party integrations — alongside senior engineers who'll review your code, pair on tricky problems, and help you level up. We're not looking for someone who has done it all. We're looking for someone who is genuinely curious, writes thoughtful code, and wants to build systems that healthcare teams rely on every day.
What You'll Do
Build and maintain backend services and features using Node.js / Express, with guidance from senior engineers on architecture and design decisions.
Design and develop RESTful APIs, learning what makes them clean, scalable, and secure.
Work with our databases (MongoDB and PostgreSQL/MySQL) — writing and optimising queries, modelling data, designing schemas, and learning when to reach for which.
Build integrations with external systems and third-party APIs, handling retries, rate limits, and failure cases gracefully.
Work on background jobs, queues, and scheduled workflows that keep provider data in sync.
Get hands-on with AWS (EC2, S3, Lambda, RDS) as part of day-to-day development and deployment.
Take part in product and design discussions — your perspective matters, even early on.
Write clean, testable code and participate in code reviews (both giving and receiving feedback).
Help troubleshoot issues, debug production bugs, add logging and monitoring, and contribute to making the system more reliable over time.
What We're Looking For
Must-Have
Around 1 year of hands-on backend development experience — internships, a first job, or a mix of both all count.
Working proficiency in Node.js and Express — comfortable building real APIs, not just tutorial projects.
Solid understanding of REST API design, HTTP, and how clients and servers actually talk to each other.
Familiarity with at least one database (MongoDB, PostgreSQL, or MySQL) — you can write queries, understand indexes at a basic level, and reason about how data is structured.
Some exposure to AWS or any cloud provider — even deploying a personal project counts.
Strong fundamentals in JavaScript, Git, and debugging.
Nice-to-Have
Curiosity about AI/ML — you don't need production experience, but if you've experimented with LLM APIs (OpenAI, Anthropic, etc.), built something with them for a hackathon or side project, or simply enjoy exploring the space, tell us about it.
Exposure to TypeScript, or to Python for scripting and data work.
Familiarity with Docker, CI/CD pipelines, or basic deployment workflows.
Experience with caching (Redis), message queues, or async job processing.
Understanding of authentication patterns (JWT, OAuth) and basic web security concepts.
Exposure to writing tests (Jest, Mocha, or similar).
A visible portfolio — GitHub contributions, side projects, hackathon work, or open-source contributions.
