Founding Engineer

Bixoto is a tech company building an integrated commerce platform where AI is native to the stack, not added on top of a third-party store.

Over the last five years, we built the hard parts first: our own storefront, product and supplier data platform, order orchestration layer, warehouse management system, and internal backoffice. Today we operate in France and Spain, work with 50+ suppliers, manage a catalog normalized across 500k+ products, and run multi-country logistics on software we built ourselves.

The company was bootstrapped for almost six years. We grew to around €10M in annual revenue with a team of fewer than 10 people, then closed a €1M seed round to accelerate the next phase.

That next phase is our most ambitious one yet: building the first fully integrated agentic commerce platform. Our challenge now is not to add an AI layer on top of somebody else’s system. It is to use the infrastructure we already own, improve the data and automation underneath it, and turn that foundation into a much more powerful company.

How we build

Bixoto is, above all, a technology company.

We believe a small team can achieve very large goals when each person is empowered to help build the company, not just execute tickets. We believe great technology creates leverage: with the right systems, data, and tooling, a handful of people can do work that would require much larger teams elsewhere.

This shapes how we work:

• we keep teams small and give people real ownership
• we build internal systems when they create long-term leverage
• we care about automation because developer time is the main bottleneck
• we expect people to challenge what exists, test assumptions, and propose better ways to do things

This is a challenging environment. You will continuously learn new things, work on problems across multiple layers of the stack, and have a visible impact on the company.

Your mission

As part of the Bixoto team, your mission will be to improve the systems that power the business: data integration, internal tooling, automation, and the technical foundations for our next generation of agentic workflows.

As a key member of the team, you will:

• help shape technical strategy and discuss trade-offs
• design, build, and improve systems from scratch
• improve how we integrate, normalize, and use product and supplier data
• work in fast cycles of improvement and releases
• contribute to the systems behind the website, internal tools, and operational workflows
• use new technologies, including AI and agentic workflows, when they create real leverage
• think critically, measure results, and challenge existing assumptions
• see the impact of your work live on the website and in operations very quickly

Why are you the right person?

You are the right person if you are:

• passionate about software and new technologies
• motivated by impact, ownership, and building useful things
• excited to work in a place where there is a lot to learn
• ready to question what is in place and propose better solutions
• serious about craftsmanship in implementation
• self-starting and entrepreneurial

It is not a problem if you do not already know every technology or language we use. What matters more is that you are curious, learn fast, and want to contribute at a high level.

You are also:

• humble and eager to grow
• motivated to learn every day
• collaborative, and happy to learn from others and share what you know
• comfortable working across different types of problems when needed
• fluent in English

French and Spanish are strong advantages.

But above all, we are looking for curiosity, energy, and high potential.

If you bring a specific talent we did not think of, we want to hear about it.
