Senior Fullstack Developer (Next.js & NestJS)

We are building a high- performance Data & Supply Chain platform where business logic and data integrity are paramount. We are looking for a Senior Engineer who can bridge the gap between complex system requirements and production- ready code.
RESPONSIBILITIES:

Technical Leadership: Establish coding standards, conduct rigorous code reviews, and mentor mid- level developers. You are the "Quality Gatekeeper."
Database Stewardship: Lead the database restructuring initiative. You will design normalized schemas, plan migration strategies to minimize downtime, and optimize complex queries for performance at scale.
System Architecture: Lead the implementation of scalable backend patterns using NestJS. You will be responsible for enforcing Clean Architecture boundaries and transitioning monolithic modules into decoupled services where necessary.
AI Integration: Design and implement the integration of AI modules (Vector Search, RAG pipelines) into the core business logic.
Advanced Frontend Engineering: Architect the Next.js 14+ frontend application. You will define patterns for Server Actions, caching strategies, and reusable component composition to ensure high performance (Core Web Vitals).

TECHNICAL REQUIREMENTS
Backend & Data

Database: Advanced proficiency in PostgreSQL.
Framework: Expert mastery of Node.js and NestJS. You understand the event loop, streams, and memory management deeply.
Vector & Search: Experience implementing Vector Databases (pgvector, LanceDB, or Weaviate) and designing data ingestion pipelines for RAG (Retrieval- Augmented Generation).

Frontend

UI Architecture: Ability to build complex, compound components using headless libraries (shadcn/ui, Radix UI) and Tailwind CSS.
Framework: Expert knowledge of React.js and Next.js (App Router). You can explain the architectural trade- offs between SSR, CSR, and ISR in depth.
Performance: Experience debugging render cycles, memory leaks, and optimizing bundle sizes.

Tools & Workflow

Scientific Rigor: You don‘t guess; you measure. You use metrics and logs to prove your optimizations work.
Mindset & Work Ethic
Outcome- Focused: You value shipping robust software over debating tools. You make pragmatic technical trade- offs and can articulate why you made them.
Product- Oriented: You don‘t just write code; you build products. You proactively identify gaps in the requirements and suggest improvements that align with business goals.
AI- Assisted Coding: You treat AI coding tools (Cursor, Copilot) as a force multiplier. You know how to prompt for architectural patterns and rigorously audit the output for security and logic flaws.
Independent & High Agency: You can take a vague requirement like "Improve search accuracy" and turn it into a concrete technical roadmap without needing to be managed.
Extreme Attention to Detail: You care about "invisible" quality—error handling, logging, data consistency, and edge cases. You assume things will break and code defensively.

Nice to Have

Deep knowledge of Authentication protocols (OAuth2, OIDC) and security best practices (OWASP).
Experience designing Microservices or Event- Driven Architectures (Kafka, RabbitMQ).
Experience with Headless CMS (Payload CMS) and designing content models.
Experience with Monorepo tooling (Turborepo/Nx) in a production environment.
