Job Description

Role Summary

We are looking for a AI (Fullstack) Engineer to help evolve IFS.ai Logistics into an agent‑first, AI‑native product.

This is not a traditional “add AI to an existing system” role.

You will design and build LLM‑powered agents, simulation‑driven workflows, and AI‑native product capabilities that sit at the core of our logistics optimization platform.

You will work across frontend, backend, data, and infrastructure, owning problems end‑to‑end and shaping how we build software — not just what we build.

What You’ll Work On

AI‑Native & Agent‑First Development

Design and build LLM‑driven agents to support planning, optimization, and decision‑making workflows
Develop agent orchestration patterns (tools, memory, evaluation, guardrails)
Build and maintain RAG pipelines, structured prompting, and retrieval strategies
Treat simulation as a first‑class design tool (using synthetic data, scenario replay, and state machines to validate logic)

Fullstack Product Engineering

Build end‑to‑end product features spanning:
- Backend services (Python / TypeScript)
- APIs (REST / GraphQL / FastAPI)
- Frontend experiences (React)
Create human‑in‑the‑loop interfaces for AI systems (review, override, explainability)
Collaborate closely with Product and Design to ship usable, explainable AI features

Platform & Engineering Quality

Own services in production: performance, reliability, observability, and cost
Design systems that are secure, testable, and compliant by default
Use infrastructure‑as‑code and modern CI/CD practices
Champion simulation‑led design, testability, and fast feedback loops

What Success Looks Like (6–12 Months)

AI agents are shipping as core product capabilities, not experiments
Simulation and synthetic data are actively used to design and validate features
Product teams can move faster because AI systems are observable, testable, and trusted
Engineering quality improves without slowing delivery

Why IFS.ai Logistics

IFS.ai Logistics is building the next generation of logistics optimization software — combining AI, simulation, and human expertise to reduce cost, emissions, and complexity in global supply chains.

You’ll work on hard problems, with real‑world impact, alongside a team that values design‑led thinking, technical depth, and autonomy.

Qualifications

What We’re Looking For

Core Experience

Strong fullstack engineer with deep backend capability
Production experience with Python and/or TypeScript
Experience owning systems from concept to production
Comfortable working in small, high‑ownership teams

AI & Data (Practical, Not Theoretical)

Hands‑on experience with:
- LLMs and modern AI tooling
- RAG systems, embeddings, vector search
- Agentic patterns (tools, planners, evaluators)
Experience productionising ML/AI systems (monitoring, failure modes, iteration)
Pragmatic mindset: understands where AI adds value — and where it doesn’t

Ways of Working

Agent‑first, spec‑driven, or simulation‑led mindset
Comfortable operating with ambiguity
Strong collaborator with Product, Design, and other engineers
Bias toward shipping, learning, and iterating

Nice to Have (But Not Required)

Experience with logistics, optimization, or simulation‑heavy domains
Background in data engineering or ML platforms
Experience building developer tools or internal platforms
Exposure to regulated or security‑conscious environments

Tech Stack

Backend: Python (Django / FastAPI), TypeScript (Node.js)
Frontend: React
AI: LLMs, RAG pipelines, agent frameworks
Infra: Cloud (AWS / GCP), Docker, CI/CD, IaC
Data: SQL, event‑driven systems, analytics pipelines

Additional Information

We embrace flexibility and hybrid work opportunities to support diverse needs and lifestyles, while also valuing inclusive workplace experiences. By fostering a sense of community, we drive innovation, strengthen connections, and nurture belonging. Our commitment ensures you can work in a way that suits you best, while also engaging with colleagues to share ideas and build meaningful relationships.
