Engagement Length: Full Time

Frontend React Developer

We are looking for a talented Frontend React Developer to create engaging and user-friendly chat and flow interfaces for our web application. The ideal candidate will have a strong focus on front-end development and a good understanding of design and UX principles. This role will involve modernizing an existing platform and building new interfaces from the ground up.

Responsibilities:

Modern React & Hooks

• Architect, develop, and maintain React 18+ applications using functional components and hooks (e.g. useState, useEffect, useContext, custom hooks).

UX & User-Centric Design

• Translate user stories and wireframes into high-fidelity components, with a special emphasis on conversational/chat UIs and multi-step flows.
• Champion accessibility and intuitive design throughout the development lifecycle.

AI-Focused Chat Integrations

• Build robust chat interfaces that connect to AI/ML services (OpenAI, custom LLMs) via RESTful APIs.
• Handle streaming responses, partial renders, user interruptions, and graceful error handling.

RESTful API Connectivity

• Implement secure, CORS-compliant data flows using HTTP, JSON, and authentication schemes (OAuth2, JWT).
• Manage async state, loading indicators, retries, and rollbacks.

Flow Design & Execution Plans

• Design and execute multi-input → AI processing → visualization pipelines (e.g. forms + file uploads → LLM analysis → charting).
• Define clear loading/error states, retry logic, and rollback strategies.

Legacy Modernization

• Refactor or incrementally migrate class-based and jQuery-driven UIs into modular, testable React components.

Collaboration & Mentorship

• Own feature delivery end-to-end, from planning through QA and deployment.
• Collaborate with senior architects and peers

Documentation & Knowledge Transfer

• Maintain up-to-date architectural diagrams, design docs, inline code comments, and onboarding guides
• Ensure all code is well-documented for future team members and audit purposes

Qualifications:

Experience: proven experience of frontend development, with at least 2 years focused on React 18+ in a production environment.

Technical Skills:

• Deep expertise with React Hooks and functional components.
• Strong design sensibility; experience translating wireframes into polished, accessible UI.
• Proven track record integrating chat UIs with AI/ML services (e.g. OpenAI).
• Solid understanding of HTTP, CORS, JSON, OAuth2/JWT, and async state management.

Problem Solving: Skilled at architecting multi-step flows, error states, and retry/rollback mechanisms.

Modernization: Prior experience refactoring legacy front-ends into React.

Collaboration: Excellent communicator, able to work closely with designers, product managers, and backend teams.

Ownership: Self-starter mentality, comfortable owning features end-to-end and guiding junior teammates.

Backend Node.js Developer

We’re looking for a talented Backend Node.js Developer to help build and maintain a future-proof, enterprise-grade RESTful API platform. You’ll own the core infrastructure, orchestrate complex business logic and AI-driven chat flows, and ensure our system is secure, extensible, and well-documented for the whole team.

Responsibilities:

Design & Build RESTful APIs

• Develop versioned, standards-compliant endpoints (pagination, HATEOAS)
• Define clear Swagger/OpenAPI specs for frontend collaboration

Modern Authentication & Security

• Implement OAuth2, JWT, API keys and integrate with AWS Cognito or Okta
• Enforce input validation, encryption, vulnerability scanning, and IP protection

Dynamic Service Abstraction

• Architect a plugin/adapter framework so new external services (third-party or internal) can be onboarded via configuration or database entries
• Maintain a runtime service registry for discovery and connector instantiation

AI-Powered Chat & Flow Orchestration

• Build both API-side and DB-side support for conversational flows: session/state tracking, turn history, context windows
• Create abstractions over multiple LLM providers (OpenAI, Google AI, AWS Bedrock), handling streaming, retries, fallbacks, and context-sharding
• Persist “flow” definitions in your database that drive multi-step AI interactions (prompt → parse → enrich → respond)

Database Design & Access Layers

• Lead MySQL schema design, indexing strategies, connection pooling, and query optimization
• Develop or extend a custom ORM/data-mapper that can adapt to dynamic models defined in the database
• Integrate NoSQL/document stores for chat transcripts, audit logs, or session data

Scalable, OOP Architecture in Node.js

• Apply SOLID principles with layered architecture (Controllers → Services → Repositories → Models)
• Define abstract base classes and interfaces for adapters, using dependency injection for testability

Complex Business Logic & Workflow Engines

• Encode domain rules, state machines, conditional flows, audit trails, retry policies, and error-compensation strategies

Collaboration & Agile Rituals

• Partner closely with React frontend engineers: mock endpoints, demo new APIs, troubleshoot integration issues
• Participate in daily stand-ups, sprint planning, reviews, and retrospectives; track progress and blockers in Jira (or similar)

Documentation & Knowledge Transfer

• Maintain up-to-date architectural diagrams, design docs, inline code comments, and onboarding guides
• Ensure all code is well-documented for future team members and audit purposes

DevOps, Git & CI/CD

• Champion GitFlow/GitHub Flow, conduct PR reviews, and drive automated CI pipelines (GitHub Actions, CircleCI)
• Write unit and integration tests, enforce linting and static analysis

Containerization & Serverless Deployment

• Dockerize services, author AWS Fargate task definitions, and manage deployments via IaC (CloudFormation, CDK, or Terraform)

Qualifications:

• Proven experience as a Backend Node.js Developer designing and delivering production REST APIs
• Proven track record with modern auth (OAuth2, JWT, Cognito/Okta) and secure coding practices
• Deep expertise in MySQL schema design, performance tuning, connection pooling, and custom ORMs
• Solid understanding of OOP, SOLID design, and layered architecture in Node.js (ES modules, async/await)
• Hands-on experience integrating multiple LLM services (OpenAI, Google, AWS Bedrock), managing streaming and fallbacks
• Prior work on plugin/adapter or dynamic service registration architectures
• Strong collaboration skills with frontend peers; comfortable defining and iterating API schemas
• Familiarity with agile rituals (daily stand-ups, sprint ceremonies) and tools like Jira or Trello
• Excellent documentation skills: API specs, design docs, and inline comments
• Experience with Git strategies, CI/CD pipelines, and containerization (Docker, AWS Fargate)
• Bonus: experience with NoSQL/document stores for chat logs or state persistence

If you’re passionate about building secure, scalable, AI-driven backend systems and enjoy collaborating in a fast-paced Agile environment, we’d love to hear from you!
