The Opportunity

We are seeking a Full Stack Engineer to develop and shape critical systems in Emerging Digital Organization.

Required Qualifications

Technical Skills

Frontend (Production Experience)

• 5+ years of Angular (including handling version migrations, optimizing change detection, and guiding teams through reactive patterns)

• Strong TypeScript skills with generics, discriminated unions, and strict mode

• RxJS depth: You understand hot vs. cold observables, unsubscription patterns, and can identify potential memory issues in reviews

• NgRx state management: You've designed stores at scale, optimized selectors, and evaluated architectural implications

• CSS Grid & Responsive Design: You can assess component hierarchy and layout decisions

• Material Design: You've worked within it and know when and how to extend it

Backend (Production Experience)

• 5+ years of Python (async/await, type hints, data modeling)

• FastAPI production experience: session management, dependency injection, middleware

• SQL and ORMs (SQLAlchemy): You write efficient queries and review them critically

• AWS services: Understanding of Lambda behavior, IAM least-privilege patterns, VPC networking

• REST API design: Versioning, error handling, idempotency

• Testing frameworks: pytest, testing strategies, integration patterns

Infrastructure (Production Experience)

• Terraform: 3+ years managing production infrastructure, understanding state and modules

• AWS fundamentals: VPC, security groups, IAM, API Gateway, RDS, DynamoDB, S3

• An understanding of why Terraform modules are structured certain ways and where conventions matter

Full-Stack Perspective

• Experience working on systems where decisions in one layer affect another

• Understanding of how Lambda cold-start implications affect frontend architecture

• Experience optimizing database queries based on how the frontend uses data

• Ability to trace a complete request flow: frontend event → HTTP request → API Gateway

→ Lambda → database → response

Education & Experience

• Bachelor's degree in Computer Science, Software Engineering, or equivalent professional experience

• 5+ years of professional software development

• 5+ years with emphasis on full stack

• 3+ years in a lead or senior engineer role

Desired Qualifications

Platform & SaaS Experience

• Low-code/No-code platform development: You've architected the infrastructure behind visual builders, workflow engines, configuration-driven systems, or similar platforms where users create applications/workflows/content

• Multi-tenant SaaS architecture: Experience with isolation strategies, namespace management, per-customer customization, and security considerations

• Dynamic content rendering systems: You've built backends that generate and serve user-created schemas (forms, workflows, layouts) where structure isn't known at compile time

• Schema evolution and versioning: You've navigated challenges like handling version transitions when users have existing data in old schemas

• Generator/builder architecture patterns: You understand the differences between code generation, configuration generation, and content rendering, and have made informed trade-off decisions

Design Systems & Component Architecture

• Enterprise design system experience: You've worked with or led component libraries (Helix, Fluent, Carbon, Material, Chakra) where design tokens, API contracts, and versioning are important

• Design system adoption: You've guided teams on using component libraries—when to use existing components, when to extend them, when to create new ones

• Theming and customization: Experience building theme systems where a base (like Material Design) can be customized for brand and enterprise requirements

• Component versioning: You've navigated breaking changes in component libraries, communicated upgrade paths to teams, and evaluated impact

• Design-engineering collaboration: You've worked with design teams to balance design intent with engineering constraints

• Styling at scale: You've made informed decisions about styling approaches (CSS-in-JS, scoped styles, etc.) in multi-team component libraries

Technical Stack Preferences

• Experience with LLM integration (prompt engineering, token optimization, error handling)

• NestJS or other enterprise Node.js frameworks

• Cypress for testing

• Azure AD/MSAL authentication

• AppSync and WebSocket communication patterns

• CI/CD pipeline design and GitHub Actions

• Mentoring developers through full-stack transitions

• Performance profiling and optimization across frontend and backend layers
