The team values engineers who use AI tools daily to develop faster and more effectively.

Responsibilities

• Develop user-facing features with Next.js (SSR/SSG, routing, data fetching) and Tailwind CSS (responsive, accessible UI).
• Design and implement backend services on Encore: define service boundaries, APIs, data flows, and integrations.
• Own features end-to-end: requirements, architecture, implementation, testing, deployment, and monitoring.
• Model data, manage database migrations, and optimize queries using ORMs (Prisma/Drizzle) on PostgreSQL.
• Improve quality with thoughtful code reviews, automated testing (Jest, Playwright), and efficient CI/CD workflows.
• Use AI/LLM tools daily for code generation, testing, refactoring, documentation, and prototyping; integrate AI capabilities into the product where beneficial.

Requirements

• 5+ years of professional full-stack experience in the Node.js + React ecosystem.
• Production experience with Next.js and Tailwind CSS.
• Strong understanding of backend and microservice architecture (service decomposition, API design, monitoring, observability).
• Hands-on backend experience with Express, Fastify, or similar frameworks; willingness to learn Encore (Encore experience preferred).
• Proficiency in TypeScript and working with ORMs (Prisma, Drizzle) on PostgreSQL/MySQL.
• Daily use of AI tools to support and accelerate development.
• Strong communication skills, ownership mindset, and ability to ship high-quality features consistently.

Nice to Have

• Experience with NestJS or other Node.js frameworks.
• Familiarity with GraphQL, WebSockets, message queues (BullMQ), and Redis caching.
• Cloud deployment experience (Vercel, AWS, GCP), Docker, and Infrastructure as Code basics.
• Knowledge of secure coding practices, including OWASP, OAuth2/JWT, and secrets management.
• Experience integrating LLM APIs or developing AI-assisted product features.

About Us

We are a well-funded startup in the logistics-tech space, building a high-performance B2B platform from the ground up. Our goal is to replace outdated, manual workflows with a modern, scalable, and real-time application.

We are tackling complex business logic head-on. Our system is built on a sophisticated multi-tenant architecture to support complex organizational structures and advanced, permission-based workflows.

We have a clear, developer-focused "Smart Hardcoding" strategy for our MVP: we build the "right" scalable API-first foundation now, while "hardcoding" the UI for speed. We are looking for a true engineer to lay this foundation with us.

The Role: Founding Engineer

As the first core engineer, you will be responsible for building the entire technical foundation based on a detailed specification. This is an architecture-heavy role for a self-motivated builder.

• Build the core Modular Monolith backend using NestJS.
• Implement a complex, secure multi-tenant architecture (managing Users, Profiles, and Tenants).
• Implement our "Smart Hardcoded" RBAC (Permissions) system.
• Build a clean, API-First service (JSON only), knowing it will be consumed by both React (Web) and React Native (Mobile).
• Implement the core business logic: a complex load/offer management system, internal collaboration tools.
• Integrate core third-party services like Clerk (Auth) and Pusher (Real-time).

Our Tech Stack (Non-Negotiable)

• Backend: NestJS, Prisma, PostgreSQL
• Frontend: React (Vite), MUI, React Query, React Hook Form
• Mobile (v2.0): React Native (Expo)
• Language: TypeScript (Monorepo with shared-types)
• Auth: Clerk
• Real-time: Pusher

Who We're Looking For (Requirements)

• 5+ years of professional software engineering experience.
• Proven, hands-on experience building Multi-Tenant SaaS applications. (This is the most critical requirement).
• Expert-level knowledge of Node.js + TypeScript, preferably with NestJS.
• Strong expertise in React and its modern ecosystem (React Query is a must).
• Deep understanding of API-First design and Prisma (or similar modern ORMs).
• You understand the difference between a "quick-hack" MVP and a "scalable-foundation" MVP.
• You are autonomous, a strong problem-solver, and can own the entire stack.

Bonus Points (Nice to Have):

• Experience with React Native (Expo).
• Experience in the Logistics or B2B Marketplace domain.
• A strong understanding of database security and performance.

What We Offer

• The chance to be the #1 engineer and build a complex product from scratch.
• A fascinating architectural challenge (not just another CRUD app).
• A clear product vision and detailed technical specification (MDD) ready for development.
• Fully remote (Ukraine).
• Competitive compensation (we are open to hourly, part-time, or full-time engagement).

How to Apply Please send your CV, GitHub/LinkedIn, and a brief note explaining why this specific technical challenge (B2B, Multi-Tenancy, API-First) is interesting to you.

About the role

We are hiring a Senior Full Stack Engineer to own major surfaces across backend, data, frontend, and system design in an early stage startup environment. This is a builder role: you will ship production features fast, make pragmatic tradeoffs, and iterate directly with customers. You will work across ingestion pipelines, graph and DAG workflows, LLM driven agent systems, copilot UX, and media generation.

You should be comfortable operating with ambiguity, changing priorities, and incomplete requirements. You will be expected to propose solutions, implement them end to end, and harden them for production.

What you will do

1. Build and ship production SaaS capabilities end to end across backend, data, and frontend.
2. Design and implement LLM powered agent workflows using LangChain and LangGraph, including tool calling, routing, memory patterns, evaluation, and guardrails.
3. Deliver GraphRAG experiences, including retrieval, citation, and copilot interactions inside the product.
4. Build ingestion pipelines for GEDCOM, images, and PDFs, handling real world variance, dedupe, entity resolution, and source classification (primary vs secondary).
5. Own AI and media generation integrations (Claude Sonnet, FAL.ai, Remotion and FFmpeg), including reliability, cost controls, and latency optimization.
6. Build graph visualization and interaction patterns for complex trees and DAGs (GoJS, and evaluate alternatives such as Cytoscape).
7. Lead frontend development using React, Vite, TypeScript, TanStack Router and Query, Tailwind, and shadcn/ui.
8. Lead backend architecture with Python, FastAPI, CopilotKit, and PydanticAI, integrating LangChain and LangGraph where appropriate.
9. Design data models and graph workflows using Neo4j (Neomodel) and PostgreSQL (SQLAlchemy).
10. Improve system reliability and operability: observability, tracing, error recovery, performance tuning, and safe deploys.
11. Drive technical decisions, simplify complexity, set engineering standards, and raise the bar on code quality.

Examples of projects you might own

1. Build discovery and ingestion pipelines that unify searches across APIs, parse structured metadata for import, dedupe entities, and auto tag sources as primary or secondary.
2. Implement verification and correlation engines using LangGraph to compute confidence scores, detect duplicates, flag conflicts, and generate explainable reports inside the copilot experience.
3. Build an agent tool layer with deterministic APIs for graph operations, retrieval, and data normalization, with evaluation harnesses to prevent regressions.

What success looks like (first 3 to 6 months)

1. You independently deliver large, chunked product features end to end and get them into customer hands.
2. You reduce complexity through better boundaries, data contracts, and reusable primitives across agents, ingestion, and graph ops.
3. You improve reliability and developer velocity via observability, stronger testing, evaluation for agent flows, and safer deployments.
4. You influence roadmap and architecture through strong judgment, crisp communication, and customer driven iteration.

Preferred experience

1. 7+ years building and shipping production systems with meaningful ownership.
2. Proven startup execution: shipping in small teams, moving fast, iterating with customers, and handling ambiguity and changing requirements.
3. Strong experience building LLM powered systems using LangChain and or LangGraph, including tool calling, retrieval workflows, memory strategies, and evaluation.
4. Experience with graph data models and performance tuning (Neo4j strongly preferred).
5. Experience with messy real world data ingestion and entity resolution.
6. Strong product and UX sensibility: simplify complex data workflows into usable end user experiences.
7. Strong judgment around interfaces, maintainability, and scope control.
