Description

Design it, build it, and own it in production.
Anyone can draw a system diagram. What sets great architects apart is what happens after: whether the design holds when traffic grows tenfold, whether security survives a real audit, and whether teams can still build on it two years later.

Techdome designs and runs production-grade platforms in FinTech, Healthcare, AI, SaaS, and more, including our own products JustInterview.ai (AI hiring) and Sparrow (API testing). Our systems handle sensitive patient data and real financial transactions at scale. We’re looking for a hands-on Software Architect to shape how these platforms are built, write code alongside the team, and stay accountable for how they perform in production.

What You’ll Do
  • Own the architecture: System design, APIs, data models, security, scalability, observability, and cloud cost.
  • Build security in: Design PHI and payment flows with compliance part of the architecture, not a retrofit.
  • Drive cloud-native delivery: MERN platforms on AWS/GCP/Azure with Kubernetes, CI/CD, IaC, and secrets management.
  • Make the hard calls: Monolith vs. microservices, event-driven design, integrations, build vs. buy. Decide, document, and stand behind it.
  • Own reliability: Uptime, latency, and throughput as usage grows; lead incident response and root-cause analysis.
  • Set the standard: Reference architectures, reusable patterns, and practical engineering guidelines.
  • Stay hands-on: Write code, run design reviews, and review PRs every week.
  • Think like the client: Translate business goals and constraints into architecture that fits.
  • Grow leaders: Mentor senior engineers and develop future tech leads.
Your First 90 Days
  • Days 1–30: Learn our products, codebases, and infrastructure, and identify the biggest architectural risks and opportunities.
  • Days 31–60: Lead a significant design decision from proposal to production and take a visible role in design reviews.
  • Days 61–90: Introduce standards or patterns that teams adopt, and become the go-to technical authority on a core platform.
Must Have
  • 6+ years in software engineering with clear ownership of architecture decisions
  • Experience running a production system with 100,000+ users
  • Proven track record of solving serious scale and performance bottlenecks
  • Strong hands-on Node.js and React (MERN preferred) with TypeScript
  • Solid cloud architecture experience on AWS, GCP, or Azure
  • Background in healthcare, fintech, payments, insurance, or another high-security domain
  • Deep understanding of distributed systems, API design, databases, and reliability
  • Ability to explain and defend technical decisions to technical and non-technical audiences
Nice to Have
  • HIPAA/PHI, PCI-DSS, GDPR, or SOC 2 compliance experience
  • Stripe, Braintree, Adyen, or tokenization experience
  • High-availability, event-driven, or microservices systems
  • Consultancy or product-studio experience across multiple clients
  • Daily use of AI coding tools (Claude Code, Cursor, GitHub Copilot)
Why Techdome
  • Independent and profitable: No investor pressure. We play the long game.
  • Real influence: Set engineering standards for an 80+ engineer team.
  • Fast path to production: Your designs ship quickly and reach real users.
  • Global team: Engineers across India, Dubai, and the US.
