About the role

About the Role

We're looking for a Senior Full Stack Developer to design, build, and operate end-to-end features across our Angular front end and Node.js back end, deployed on AWS. You'll own your work from architecture through production, including the CI/CD pipelines that ship it, and work closely with product and design to turn requirements into reliable, scalable systems.

Key Responsibilities

  • Design and build responsive, performant UI components in Angular, and robust REST/GraphQL APIs and services in Node.js Architect full-stack features end to end, making sound trade-offs between front-end and back-end implementation
  • Deploy and manage workloads on AWS (e.g., EC2, Lambda, ECS/EKS, S3, RDS, CloudWatch), optimizing for cost, scalability, and reliability
  • Build and maintain CI/CD pipelines (e.g., Jenkins, GitHub Actions, GitLab CI) to automate testing, builds, and deployments
  • Own code quality through testing (unit, integration, e2e), code reviews, and monitoring/observability in production
  • Collaborate with product managers, designers, and other engineers to scope, estimate, and deliver features
  • Mentor junior and mid-level developers, and contribute to technical standards and architecture decisions
  • Troubleshoot and resolve production issues, participating in on-call rotations as needed

Required Skills

& Experience Strong hands-on experience with Angular (v10+), including RxJS, component architecture, state management, and performance tuning Strong Node.js experience building scalable APIs and services (Express, NestJS, or similar) Solid AWS skill set: core services (EC2, Lambda, S3, RDS/DynamoDB), IAM, networking basics (VPC), and cost-aware architecture Hands-on CI/CD experience: building and maintaining pipelines, infrastructure as code (Terraform or CloudFormation), and automated deployment strategies Proficiency in TypeScript/JavaScript across the full stack Experience with relational and/or NoSQL databases (PostgreSQL, MongoDB, DynamoDB) Strong grasp of testing practices (Jest, Jasmine/Karma, Cypress or Playwright) Familiarity with containerization (Docker) and orchestration (Kubernetes or ECS) Comfortable owning systems in production, including debugging, monitoring, and incident response Good to Have Experience with serverless architectures (AWS Lambda, API Gateway, Step Functions) Exposure to microservices and event-driven architecture (SQS, SNS, EventBridge, Kafka) Experience with Infrastructure as Code (Terraform, CDK, or CloudFormation) and GitOps workflows Familiarity with observability tooling (Datadog, New Relic, Grafana/Prometheus) Exposure to security best practices (OWASP, secrets management, IAM least-privilege) Prior experience in a lead or architect-track role, or driving technical decisions across teams Qualifications 8-10 years of professional software development experience, with at least 5+ years in full-stack roles spanning Angular and Node.js Demonstrated experience owning production AWS infrastructure and CI/CD pipelines Strong communication skills and a track record of mentoring other engineers

Technical questions 5
Explain OOP (Object-Oriented Programming) principles with real-world examples in Leadership. Answer
Model answer: 1. Encapsulation (data hiding via private fields/getters). 2. Abstraction (hiding implementation complexity). 3. Inheritance (code reusability). 4. Polymorphism (method overriding/overloading).
What is the time and space complexity of QuickSort vs MergeSort? Answer
Model answer: QuickSort: Average O(N log N) time, O(log N) space. Worst O(N^2). MergeSort: Guaranteed O(N log N) time, but requires O(N) auxiliary space.
Explain the difference between SQL Indexing (B-Tree vs Hash) and when not to use an index. Answer
Model answer: Indexes speed up SELECT queries via B-Trees. However, they slow down INSERT, UPDATE, and DELETE operations because indexes must be updated on disk. Avoid on low-cardinality columns (e.g., boolean flags).
What happens under the hood when you enter a URL in a browser? Answer
Model answer: 1. DNS lookup (resolves IP). 2. TCP 3-way handshake (SYN, SYN-ACK, ACK). 3. TLS negotiation for HTTPS. 4. HTTP GET request sent. 5. Server responds with HTML/CSS/JS. 6. Browser renders DOM & CSSOM tree.
What is the difference between REST and GraphQL APIs? Answer
Model answer: REST uses multiple fixed endpoints with possible over/under-fetching. GraphQL uses a single endpoint allowing clients to query exact fields in a single request.
