Senior Frontend Engineer (Angular, Multi-Tenant, Micro-Frontends)

About Sotaog

At Sotaog , we build data-driven, intelligent platforms that power industrial operations across energy and manufacturing sectors. Our products combine real-time analytics, machine learning, and scalable cloud architecture to bring the precision and reliability of big tech to mission-critical industries.

You’ll lead the rebuild of our customer-facing frontend into a next-generation, multi-tenant, micro-frontend platform designed for scale, speed, and global deployment.

Location: Remote (US time zones preferred)

Stack: Angular, Nx, Module Federation, AWS (CloudFront, S3, Route53), CI/CD

What you’ll do

• Lead a greenfield rebuild of the Sotaog frontend using Angular + Nx (or Standalone Angular + MF) with Webpack Module Federation (or Angular Federated Modules) for modern micro-frontends.
• Architect multi-tenancy across theming, branding, routing, feature flags, per-tenant configurations, and entitlements.
• Define and own shared libraries — UI components, auth, data access layer, telemetry, and design tokens.
• Manage AWS-based frontend delivery : S3 static hosting, CloudFront distributions, Route53 DNS, cache strategies, and versioned rollouts.
• Build robust CI/CD pipelines (GitHub Actions / CodeBuild / CodePipeline) with automated tests, preview environments, and blue/green or canary deployments.
• Partner with product, design, and backend teams to ship with velocity and reliability , continuously optimizing performance and removing legacy bottlenecks.

Must-have

• 4+ years building Angular applications at scale — deep knowledge of RxJS, change detection, routing, forms, and performance profiling.
• Proven experience designing and maintaining multi-tenant apps (config-driven theming, per-tenant authorization, asset management).
• Hands-on understanding of micro-frontends — module federation, shared runtimes, version control, and cross-MFE contracts.
• Working knowledge of AWS (CloudFront, S3, Route53, IAM roles, build artifacts, environment promotion).
• Strong background in CI/CD for SPAs , including automated testing frameworks (Jest/Karma, Playwright/Cypress).
• Solid foundation in clean architecture , TypeScript discipline , and component-driven design systems .

Nice-to-have

• Nx Workspace, Angular Standalone APIs, Design Tokens (Style Dictionary), Storybook, OpenAPI/GraphQL, Sentry.
• Security best practices: CSP, subresource integrity, AWS WAF, signed cookies/URLs.

What success looks like (6 months)

• Production-grade micro-frontend shell with 2–3 independently deployable MFEs.
• Core routes achieving <2.5s p95 TTI and Lighthouse ≥ 90 across key tenants.
• Zero-downtime deployments with automated rollbacks and preview environments.
