AI Product Engineer

Present in 96 countries, we are dedicated to changing the way the world uses energy through advanced electric vehicle charging and energy management systems. We have the headquarters in Barcelona and manufacturing facilities in Spain (Barcelona), and the US (Arlington, Texas). We are rapidly becoming a leading company in the market.

In 2021, we were listed on the New York Stock Exchange (NYSE WBX), allowing us to garner acclaim and win prestigious design awards (the IF Design, Good Design, and RedDot Awards).

In 2022, we acquired ARES (an assembly electronics company) and COIL (Installers of turnkey EV charging solutions). One year later, in 2023, we acquired ABL, the leading German EV charger manufacturer, which has allowed us to have a stronger presence in Europe.

We are looking for an AI Product Crafting Engineer who can turn AI capabilities into real product features that drive measurable business impact.

This role sits at the intersection of AI engineering, backend architecture, and product thinking. You will design and build AI-powered capabilities that integrate into real software ecosystems, enabling products to both consume and expose intelligence through APIs, services, and event-driven systems.

We value engineers who build AI that ships and delivers outcomes, not just prototypes or experiments.

What You’ll Do:

Build AI-powered product capabilities

Design and implement AI features such as:

Intelligent automation workflows

Recommendation and forecasting systems

AI copilots for operational teams

AI-powered APIs and services used by other products

Your goal is to turn AI into reusable product capabilities, not isolated experiments.

Develop AI products through iterative experimentation

You will apply a build–measure–learn approach to AI development:

Start with fast experiments or prototypes

Define leading metrics that signal product impact

Validate assumptions quickly

Iterate and evolve the solution

Evolve architecture from experiment to scalable system

You will progressively evolve the architecture from:

Experiment → Validated capability → Product-grade AI system

This includes designing systems such as:

AI microservices

API-first AI capabilities

event-driven architectures

AI inference services

data pipelines and AI evaluation systems

Focus on what moves the business

We prioritize solutions that deliver measurable impact:

reducing operational costs

accelerating time-to-market

unlocking new product capabilities

generating new revenue opportunities

What We’re Looking For:

Product-oriented engineering mindset

You think in terms of:

outcomes and impact

rapid iteration

business metrics

pragmatic solutions

You’re comfortable starting with fast prototypes and evolving them into robust systems once the value is proven.

Strong backend architecture fundamentals

Experience designing and evolving systems involving:

APIs and service-oriented architectures

event-driven systems

distributed systems

data pipelines

scalable backend services

You understand how to evolve architecture from prototype to production.

Experience building AI-powered systems

You have built AI systems with real-world usage, such as:

production systems

startup products

high-impact personal projects

open source tools

We care more about what you built than where you built it.

Hands-on experience with modern AI stack

Experience with technologies such as:

LLM APIs

RAG architectures

embeddings and vector databases

AI orchestration frameworks

prompt engineering and evaluation

What Success Looks Like

Within the first months you will:

Identify high-impact opportunities to apply AI

Ship AI capabilities that integrate with real products

Validate ideas through experiments and leading metrics

Help establish architectural patterns for scalable AI systems

Mindset We Value

We value engineers who think like product builders.The goal is not to build the most sophisticated AI system —the goal is to deliver measurable impact through intelligent software.

Benefits

Flexible working hours

Hybrid work schedule and half Fridays. 

First-class private health, dental, and life insurance after your first month at Wallbox

Flexible compensation tickets valid for transportation, childcare, and restaurant/food delivery apps

Variety of breakfast and lunch dishes, every day, at a discounted price at our canteen
