This role focuses on developing production-ready Python FastAPI services , React/Next.js front-end applications , and API-driven integrations across enterprise systems.
The engineer will contribute to building maintainable, testable, and secure solutions that align with ERM’s engineering standards and help strengthen internal capability as part of cross-functional delivery teams.

Key Accountabilities & Responsibilities

Full‑Stack Application Development

• Build and maintain backend API services using Python (FastAPI) and modern engineering patterns.

• Develop responsive front-end interfaces using React / Next.js , ensuring usability, consistency, and performance.

• Implement end-to-end application logic, connecting UI components with backend services and underlying data layers.

• Ensure API contracts, service logic, and integration patterns are maintainable, well‑documented, and aligned with solution architecture.

Systems Integration & API Connectivity

• Build integrations between internal/external systems using REST, GraphQL, and event-driven patterns.

• Work with architects and platform teams to implement secure API authentication/authorization (OAuth2, JWT, SSO, etc.).

• Ensure seamless interoperability across the broader application landscape by following standard integration patterns.

Quality, Reliability & Maintainability

• Apply solid engineering practices including automated testing (unit, integration), code reviews, and peer collaboration.

• Contribute to observability (logging, metrics, tracing) and troubleshooting across environments.

• Follow secure coding practices aligned with ERM standards and industry best practices.

Data, Storage & Application State

• Work with relational databases (e.g., PostgreSQL) and design efficient data access patterns.

• Support implementation of caching, session management, and state-handling aligned with product needs.

• Collaborate with data/AI engineers where relevant for backend integration scenarios.

Collaboration & Delivery

• Work closely with architects, designers, and AI/back-end engineers within pod-based delivery teams.

• Contribute to solution delivery in line with agreed engineering standards—including maintainability, security, and operational readiness.

• Participate in knowledge transfer, documentation, and continuous improvement of delivery practices.

• Support the transition of application capabilities from third‑party vendors to internal teams where relevant.

Influence And Decision-Making Authority

• Shape implementation approaches for full-stack workflows, API integration patterns, and design of user-facing components.

• Recommend improvements to application performance, maintainability, and usability based on testing and user feedback.

• Contribute technical inputs into reusable engineering components, coding standards, and delivery practices across teams.

Job Requirements & Capabilities

Education & Experience

• Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience.

• Typically 10 + years of full-stack development experience in production environments.

• Demonstrable experience delivering end-to-end applications—including UI, API services, and integrations.

• Experience working in cross-functional engineering teams (architects, product owners, DevOps/platform engineers, etc.).

Technical Skills

• Strong Python development skills and hands-on experience with FastAPI for backend service development.

• Experience building modern front‑end applications using React or Next.js .

• Strong understanding of API design, service-to-service communication, error handling, and integration patterns.

• Experience with relational databases (SQL), ORM frameworks, and data modelling.

• Familiarity with CI/CD pipelines and working in cloud environments (AWS/Azure).

Behavioural Skills

• Strong problem-solving ability with a delivery-oriented mindset.

• Clear communicator who can collaborate across technical and non-technical stakeholders.

• Pragmatic approach to maintainability, testing, and iterative development.

• Willingness to learn, adapt, and work in fast-evolving technology environments.

Desirable / Nice to Have

• Experience with AWS services (Lambda, ECS, S3, RDS, CloudFront, API Gateway).

• Familiarity with containerization (Docker) and Kubernetes deployments.

• Exposure to frontend performance optimization and UX best practices.

• Experience in pod-based delivery or cross-functional product engineering teams.

• Exposure to AI/LLM-integrated applications or backend interaction with RAG services.
