JOB SUMMARY:

We are seeking an expert-level Senior Back-End Developer with extensive experience in JavaScript, TypeScript, AWS, MongoDB, and Node.js. The ideal candidate is highly opinionated on backend development best practices, capable of tackling complex architectural challenges, and excels in scenarios with minimal support. This role requires someone who can handle feedback constructively, adapt to high-pressure situations, and deliver results from day one.

This is not a ‘learn on the job’ position—it is a role for a seasoned professional who thrives in complex technical environments and can independently navigate challenges while collaborating effectively with team members. Attendance at occasional in-person meetups in Chicago/Midwest is required.

KEY RESPONSIBILITIES:

• Architect, develop, and maintain robust, scalable server-side applications using Node.js and Express.

• Utilize AWS services to deploy, configure, and manage secure, HIPAA-compliant applications.

• Write and maintain clean, efficient, and secure code in JavaScript and TypeScript.

• Design and implement APIs, including RESTful services and integrations with external systems.

• Lead discussions on backend architecture, including refactoring monolithic APIs into microservices or serverless systems.

• Troubleshoot, debug, and optimize performance for mission-critical applications.

• Design and manage databases, focusing on MongoDB, Postgres, and data ingestion pipelines.

• Implement SOC2-compliant solutions, ensuring robust security and data integrity.

• Collaborate with cross-functional teams to integrate front-end and back-end components.

• Provide technical leadership, conduct code reviews, and mentor junior developers.

REQUIRED SKILLS AND QUALIFICATIONS:

• 10+ years of backend development experience (or 8 years with a degree in Computer Science, Software Engineering, or a related field).

• Proficiency in JavaScript and TypeScript for server-side development.

• Extensive hands-on experience with AWS services such as EC2, S3, Lambda, and RDS.

• Expertise in MongoDB and database design, including data ingestion and warehouse solutions.

• Strong understanding of security and performance best practices, including HIPAA and SOC2 compliance.

• Deep experience in building and consuming RESTful APIs.

• Ability to independently set up and configure AWS services without DevOps support.

• Proven ability to handle high-pressure situations and complex technical challenges.

• Experience in designing and leading the implementation of complex features from top to bottom, including architecture, decision-making, and code execution.

• Strong problem-solving skills, attention to detail, and excellent communication abilities.

PREFERRED QUALIFICATIONS:

• Familiarity with microservices architectures and serverless solutions.
• Experience with CI/CD pipelines and automated deployments.
• Strong knowledge of SQL and NoSQL databases (e.g., Postgres, MongoDB).
• Experience working in both monolithic and microservice architectures.
• Understanding of DevOps practices and the ability to function in a DevOps-light environment.
• Experience in the healthcare or startup industries.
• Ability to confidently articulate opinions on complex backend topics and adapt based on constructive feedback.

TECH STACK:

• Frontend: React, Redux Toolkit, TypeScript, MUI, Bootstrap
• Backend: Node.js, Express, Mongoose, TypeScript
• Database: MongoDB (Atlas), Postgres (AWS RDS)
• AWS Services: EC2, S3, Lambda, Glue, RDS
• CI/CD: CircleCI

ABOUT YOU:

• You’re a seasoned developer with deep expertise in backend technologies and architecture.
• You can work independently with minimal guidance and deliver results quickly.
• You thrive in challenging environments and can navigate high-stakes scenarios with confidence.
• You excel at receiving and incorporating feedback without resistance.
• You have strong opinions on backend best practices but are open to constructive feedback and collaborative problem-solving.
• You are capable of jumping into a complex codebase and contributing effectively from day one.
• You value collaboration, clear communication, and supporting the overall team’s success
