About the Opportunity
At Cohort AI, we’re building technology that demands reliability, scalability, and thoughtful engineering. We’re looking for a Senior Software Engineer who brings strong full-stack experience, sharp design instincts, and a passion for building systems that are clean, testable, and production-ready. In this role, you’ll help shape our platform end-to-end—working across backend services, modern front-end interfaces, and the automation pipelines that power delivery.

You’ll collaborate closely with product, design, and engineering teammates to turn ideas into dependable software, while helping raise the bar for quality, performance, and security across our stack.

Responsibilities:

• Build and evolve full-stack features using Python/Django on the backend and React on the frontend.

• Write clean, efficient, well-tested code that reflects strong engineering standards.

• Design and maintain CI/CD workflows to support fast, reliable releases.

• Partner with cross-functional teams to refine requirements and translate them into scalable technical solutions.

• Review code, champion best practices, and help define engineering standards.

• Implement monitoring and performance tooling to ensure smooth user experiences.

• Integrate APIs, databases, and third-party services into cohesive systems.

• Investigate and resolve issues quickly to keep applications running at peak performance.

• Stay current with new tools, frameworks, and architectural patterns.

• Support and mentor other engineers while fostering a culture of curiosity and continuous improvement.

Required:

• 5+ years of professional software engineering experience, including full-stack development.

• Strong backend development skills with Python and Django.

• Solid experience building modern front-end applications, especially with React and ES6+.

• Deep understanding of HTML, CSS, and JavaScript fundamentals.

• Comfort with version control systems such as Git.

• Experience with automated testing and TDD practices (e.g., Jest, Playwright, Testing Library, or similar).

• Working knowledge of CI/CD concepts and implementation.

• Experience deploying and managing applications in cloud environments such as AWS (EC2, RDS, S3).

• Familiarity with containerization and orchestration tools like Docker and Kubernetes.

• Experience with relational and NoSQL databases.

• Strong grasp of web security fundamentals and common vulnerabilities (XSS, CSRF, etc.).

• Familiarity with design and prototyping tools such as Figma, Sketch, or Zeplin.

• Strong analytical thinking, problem-solving ability, and communication skills.

• Healthcare domain experience is a bonus, not a requirement.
