Senior FullStack Developer

• *Role Overview**

Aivar Innovations is seeking a Senior FullStack Developer to lead end\-to\-end product engineering across our AI\-powered accelerator platforms. This role owns both the frontend experience and backend service architecture — from real\-time data rendering and multi\-tenant UI isolation to scalable APIs, event\-driven pipelines, and cloud\-native infrastructure. You will shape the complete technical foundation of our enterprise\-grade

accelerators. **Roles \& Responsibilities*** Design and own the full\-stack architecture for AI\-powered accelerator products — component systems, API layers, database schemas, and cloud infrastructure.

• Build real\-time dashboards and pipeline monitoring UIs that visualise 6\-stage processing flows, handling live data streams via WebSockets and SSE.
• Implement role\-based access control (RBAC) end\-to\-end — enforcing multi\- tenant isolation at UI, API gateway, and database layers.
• Build the connector configuration UI and the corresponding backend integration layer for 50\+ enterprise data sources (APIs, databases, SaaS platforms).
• Design and expose REST and GraphQL APIs with versioning, auth token handling (OAuth2/JWT), rate\-limit management, and graceful error responses.
• Architect event\-driven backend pipelines using AWS Lambda, Step Functions, or Kafka for async AI workload orchestration.
• Implement audit\-trail interfaces and immutable logging infrastructure — surfacing decision timelines and transformation traces end\-to\-end.
• Enforce PII/PHI\-safe rendering client\-side and data masking/redaction at the API and persistence layers.
• Establish production engineering standards — CI/CD pipelines, comprehensive testing (unit, integration, E2E), performance budgets, and error monitoring.
• Collaborate with ML/AI engineers to integrate inference endpoints, handle async

model responses, and surface outputs in enterprise UI.

Must\-Have Technical Skills* React.js — deep expertise in hooks, context, concurrent rendering, and component architecture.

• TypeScript — strict typing across frontend components, API contracts, and shared libraries.
• State management — Zustand, Redux Toolkit, or React Query; managing complex async and real\-time state.
• Node.js / Python — proficiency in server\-side development with Express, FastAPI, or equivalent frameworks.
• REST and GraphQL API design — schema design, versioning, auth flows, and error boundary patterns.
• Relational and NoSQL databases — PostgreSQL or MySQL alongside DynamoDB or MongoDB for mixed workload patterns.
• AWS cloud\-native development — Lambda, API Gateway, S3, CloudFront, RDS, DynamoDB, Step Functions, or equivalent.
• Real\-time data — WebSockets, SSE, or polling patterns for live pipeline updates.
• Testing — Jest, React Testing Library, Cypress or Playwright; backend unit and integration testing.
• CI/CD — GitHub Actions, Docker, and production monitoring (Sentry or equivalent).

• *Nice to Have*** Experience integrating LLM inference endpoints (OpenAI, Bedrock, or self\-hosted models).
• Familiarity with vector databases (Pinecone, Weaviate, pgvector).
• Prior work on multi\-tenant SaaS platforms with enterprise compliance requirements.
• Knowledge of HIPAA, GDPR, or SOC2 data\-handling standards.
