Own end-to-end architecture for scalable, secure, reliable systems serving large user bases. Design MERN applications on cloud platforms, lead decisions on distributed systems and integrations, resolve production bottlenecks, define engineering standards, remain hands-on in coding and reviews, and mentor senior engineers. The role focuses on healthcare, fintech, AI, and SaaS products with stringent security and reliability requirements.
About the Role
What You’ll Do
At Techdome, architects own their systems from design through production. You’ll design scalable, secure, and reliable systems, lead key technical decisions, and set engineering standards for an 80+ member team building products in healthcare, fintech, AI, and SaaS.
- Own end-to-end architecture: system design, APIs, data models, security, scalability, observability, and cost.
- Take responsibility for the performance and reliability of systems serving large user bases.
- Design secure solutions for healthcare data (PHI) and payment workflows.
- Architect MERN applications on AWS, GCP, or Azure, using Kubernetes, CI/CD, IaC, and secrets management.
- Drive decisions on microservices, event-driven systems, integrations, and build-versus-buy.
- Resolve production bottlenecks in performance, scalability, and availability.
- Define engineering standards, reference architectures, and reusable patterns.
- Stay hands-on through coding, design reviews, and code reviews.
- Mentor senior engineers and grow future technical leaders.
Must-haves
- 8+ years in software engineering with clear architecture ownership.
- Production experience running a system with 100,000+ users (mandatory).
- A track record of solving major production bottlenecks at scale.
- Strong hands-on Node.js and React skills; MERN preferred.
- Cloud architecture experience on AWS, GCP, or Azure.
- Experience in healthcare, fintech, payments, insurance, or another security-critical domain.
- Deep knowledge of distributed systems, APIs, databases, and reliability.
- Excellent communication and the ability to justify technical decisions.
Nice-to-haves
- HIPAA, PHI, or PCI-DSS compliance experience.
- Familiarity with Stripe, Braintree, or tokenization.
- Experience with high-availability, event-driven, or microservices systems.
- A SaaS, consulting, or venture-studio background.
- Use of AI coding tools like Claude Code, Cursor, or GitHub Copilot.
- Build real products used by customers worldwide.
- Own architecture decisions with direct production impact.
- Shape the engineering standards of an 80+ person team.
- Join a profitable, stable company with minimal bureaucracy.
