Job Title – Full Stack Engineer
Job Type – Hybrid
Job Location – 151 Farmington Avenue, Hartford, CT 06156
Duration- 12 months contract
Job Description:
Required Qualifications
• 5+ years of software development experience in enterprise/web applications
• 5+ years of experience as a full stack developer building production REST APIs and microservices using Node.js/Express (or comparable Java Spring Boot/FastAPI stacks), including:
• OpenAPI/Swagger contract design — authoring and maintaining OpenAPI 3.x specs and generating Swagger UI documentation
• Authentication middleware — implementing JWT/OIDC validation and request-context propagation in Express (or equivalent)
• 4+ years of experience with Cloud Technologies such as Google Cloud Platform (preferred), Azure, or other public cloud
• services, including hands-on use of Google open-source SDKs and packages
• 3+ years of experience building front-end applications with Angular (v15+) and TypeScript, including Angular Material/CDK, RxJS, reactive forms, routing, and SCSS; ability to develop effective engineering practices and processes with responsive UI design and development. Experience with data visualization libraries such as Chart.js and client-side PDF/export tooling is highly desirable
• Experience building ETL pipelines using BigQuery, Python, and PySpark
• 3+ years of experience in Agile development practices, including:
• CI/CD with GitHub Actions — authoring workflows, reusable actions, matrix builds, secrets/OIDC-based cloud auth, and
• environment-gated deployments
• Containerized deployments to GKE — writing Dockerfiles, publishing images to Artifact Registry, and deploying via Helm
Core Kubernetes concepts — Deployments, Services, Ingress, ConfigMaps, Secrets, HPA, namespaces, RBAC, liveness/readiness probes, and resource requests/limits
GCP skill is totally negotiable if a candidate possesses another cloud experience. Please find the skill sets listed below:-
Must-Have Skills
• Python Frameworks: Strong mastery of FastAPI or Django.
• SQL: Deep understanding of database design and complex queries.
• AI Knowledge: Basic-to-mid level understanding of ML concepts or LLM integration.
• React: Expert proficiency in React 18+ and core hooks.
• OOP & Functional: Dual mindset for writing clean, optimized Python code.
• API Design: Proven experience building endpoints for high data throughput.
• Cloud Experience: Hands-on infrastructure knowledge with GCP or AWS.
Good-to-Have Skills
• Data Orchestration: Basic experience with tools like Apache Airflow.
• Performance Optimization: Frontend data virtualization (e.g., react-window) for massive datasets.
• NoSQL & Caching: Familiarity with Redis, MongoDB, or Elasticsearch.
• Data Libraries: Exposure to Python tools like Pandas, NumPy, or Pydantic.
• Next.js / Remix: Experience with modern SSR React frameworks.
Optional Skills
• Big Data Tools: Familiarity with PySpark for large-scale processing.
• CI/CD & DevOps: Experience with Docker, Kubernetes, and GitHub Actions.
