About the Role

At Techdome, software architecture goes beyond design. It involves ownership, technical leadership, and accountability for how systems perform in production.

- Own the production performance and reliability of systems serving large user bases.
- Design secure solutions involving healthcare data, Protected Health Information (PHI), and payment workflows.
- Architect applications using the MERN stack (MongoDB, Express.js, React, Node.js) and modern cloud infrastructure.
- Work with AWS, GCP, or Azure, along with Kubernetes, CI/CD, Infrastructure as Code (IaC), networking, and secrets management.
- Drive decisions on microservices, event-driven systems, integrations, and build-versus-buy strategies.
- Identify and resolve production bottlenecks across performance, scalability, and availability.
- Establish engineering standards, reference architectures, and reusable design patterns.
- Participate in coding, architecture discussions, design reviews, and code reviews.
- Mentor senior engineers and develop future technical leaders.

Required Qualifications

- 8+ years of professional software engineering experience with strong system design and architecture ownership.
- Proven production experience running a system with a minimum of 100,000 users (mandatory).
