About the Role
Join our dynamic, forward-thinking engineering team to lead the architectural design and implementation of our next-generation billing, finance, and debt-management platform. You’ll craft world-class Node.js applications—defining standards, frameworks, and best practices to ensure scalability, maintainability, and fault tolerance across our microservices landscape. This is an 6-month long contract role.
What You’ll Do
- Architectural Leadership: Define and document Node.js microservice architectures, coding standards, and module structures.
- Framework & Pattern Selection: Evaluate and introduce design patterns (e.g., CQRS, event-sourcing) and frameworks to streamline development.
- API & Platform Design: Design robust RESTful and event-driven APIs, ensuring consistency, versioning, and backward compatibility.
- Code Reviews & Style Guides: Establish and enforce coding guidelines (ESLint, style conventions) through peer reviews and automated linting pipelines.
- Scalability & Performance: Lead capacity planning, performance profiling, and clustering strategies to handle high transaction volumes.
- Mentorship: Coach fellow engineers on architecture principles, system design trade-offs, and modularization techniques.
- CI/CD & DevOps Integration: Collaborate with DevOps to embed architectural guardrails into build pipelines, container images, and deployment workflows.
Requirements
- 3+ years’ professional experience with Node.js and Express.js, with a track record of architecting complex microservices.
- Deep understanding of system design fundamentals: SOLID principles, domain-driven design, and separation of concerns.
- Proven ability to create and maintain large-scale codebases with clear module boundaries.
- Hands-on familiarity with message brokers (e.g., RabbitMQ, Kafka) and asynchronous processing patterns.
- Experience defining and enforcing coding standards, linting, and automated style checks.
- Comfortable diagramming and documenting architectures using UML or C4 models.
- Strong communication skills with an emphasis on whiteboarding and design sessions.
Nice To Have
- Experience with GraphQL schema design.
- Knowledge of serverless architectures (AWS Lambda, Azure Functions).
- Exposure to Kubernetes Operators or custom controllers.
